6 Configuring SSL in Oracle Fusion Middleware

You can secure communications between Oracle Fusion Middleware components using SSL, which is an industry standard for securing communications. Oracle Fusion Middleware supports TLS version 1.

This chapter provides an overview of SSL and how you can use it with Oracle Fusion Middleware components and applications. It contains these topics:

• How SSL Works

• About SSL in Oracle Fusion Middleware

• Configuring SSL for Configuration Tools

• Configuring SSL for the Web Tier

• Configuring SSL for the Middle Tier

• Configuring SSL for the Data Tier

• Advanced SSL Scenarios

• Best Practices for SSL

• WLST Reference for SSL

Note:

Where SSL connections are configured within Oracle WebLogic Server, this chapter provides references to the relevant Oracle WebLogic Server documentation rather than duplicating the instructions here.

6.1 How SSL Works

This section introduces basic SSL concepts. It contains these topics:

• What SSL Provides

• About Private and Public Key Cryptography

• Keystores and Wallets

• How SSL Sessions Are Conducted

6.1.1 What SSL Provides

SSL secures communication by providing message encryption, integrity, and authentication. The SSL standard allows the involved components (such as browsers and HTTP servers) to negotiate which encryption, authentication, and integrity mechanisms to use.

• Encryption provides confidentiality by allowing only the intended recipient to read the message. SSL can use different encryption algorithms to encrypt messages. During the SSL handshake that occurs at the start of each SSL session, the client and the server negotiate which algorithm to use. Examples of encryption algorithms supported by SSL include AES, RC4, and 3DES.

• Integrity ensures that a message sent by a client is received intact by the server, untampered. To ensure message integrity, the client hashes the message into a digest using a hash function and sends this message digest to the server. The server also hashes the message into a digest and compares the digests. Because SSL uses hash functions that make it computationally infeasible to produce the same digest from two different messages, the server can tell that if the digests do not match, someone had tampered with the message. An example of a hash function supported by SSL is SHA1.

• Authentication enables the server and client to check that the other party is who it claims to be. When a client initiates an SSL session, the server typically sends its certificate to the client. Certificates are digital identities that are issued by trusted certificate authorities, such as Verisign. Chapter 7, "Managing Keystores, Wallets, and Certificates" describes certificates in more detail.

  The client verifies that the server is authentic and not an imposter by validating the certificate chain in the server certificate. The server certificate is guaranteed by the certificate authority (CA) who signed the server certificate.

  The server can also require the client to have a certificate, if the server needs to authenticate the identity of the client.

6.1.2 About Private and Public Key Cryptography

To provide message integrity, authentication, and encryption, SSL uses both private and public key cryptography.

Secret Key Cryptography

Symmetric key cryptography requires a single, secret key shared by two or more parties to secure communication. This key is used to encrypt and decrypt secure messages sent between the parties. It requires prior and secure distribution of the key to each party. The problem with this method is that it is difficult to securely transmit and store the key.

In SSL, each party calculates the secret key individually using random values known to each side. The parties then send encrypted messages using the secret key.

Public Key Cryptography

Public key cryptography solves this problem by employing public and private key pairs and a secure method for key distribution. The freely available public key is used to encrypt messages that can only be decrypted by the holder of the associated private key. Together with other security credentials, private key is securely stored in an encrypted container such as an Oracle wallet.

Public key algorithms can guarantee the secrecy of a message. However, they do not necessarily guarantee secure communication because they do not verify the identities of the communicating parties. To establish secure communication, it is important to verify that the public key used to encrypt a message does in fact belong to the target recipient. Otherwise, a third party can potentially eavesdrop on the communication and intercept public key requests, substituting its own public key for a legitimate key (the man-in-the-middle attack).

To avoid such an attack, it is necessary to verify the owner of the public key with a process called authentication. trusted by both of the communicating parties, a third party known as a certificate authority (CA) can accomplish the authentication process.

The CA issues public key certificates that contain an entity's name, public key, and certain other security credentials. Such credentials typically include the CA name, the CA signature, and the certificate effective dates (From Date, To Date).

The CA uses its private key to encrypt a message, while the public key is used to decrypt it, thus verifying that the message was encrypted by the CA. The CA public key is well known, and does not have to be authenticated each time it is accessed. Such CA public keys are stored in wallets.

6.1.3 Keystores and Wallets

In Oracle Fusion Middleware, some components use the Oracle Wallet as their storage mechanism. An Oracle wallet is a container that stores your credentials, such as certificates, trusted certificates, certificate requests, and private keys. You can store Oracle wallets on the file system or in LDAP directories such as Oracle Internet Directory. Oracle wallets can be auto-login or password-protected wallets.

Oracle HTTP Server uses Oracle wallet. Configuring SSL for Oracle HTTP Server thus requires setting up and using Oracle wallets.

Other components use a JKS keystore or KSS keystore to store keys and certificates, and configuring SSL for these components requires setting up and using the appropriate keystores.

For more information about configuring keystores and wallets, see:

• Section 6.2, "About SSL in Oracle Fusion Middleware" for a fuller description of keystore and wallet usage in Oracle Fusion Middleware

• Chapter 7, "Managing Keystores, Wallets, and Certificates" for a discussion of these terms, and administration details

6.1.4 How SSL Sessions Are Conducted

The SSL protocol has two phases: the handshake phase and the data transfer phase. The handshake phase authenticates the server and optionally the client, and establishes the cryptographic keys that will be used to protect the data to be transmitted in the data transfer phase.

When a client requests an SSL connection to a server, the client and server first exchange messages in the handshake phase. (A common scenario is a browser requesting a page using the https:// instead of http:// protocol from a server. The HTTPS protocol indicates the usage of SSL with HTTP.)

Figure 6-1 shows the handshake messages for a typical SSL connection between a Web server and a browser. The following steps are shown in the figure:

1. The client sends a Hello message to the server.

   The message includes a list of algorithms supported by the client and a random number that will be used to generate the keys.

2. The server responds by sending a Hello message to the client. This message includes:

   • The algorithm to use. The server selected this from the list sent by the client.

   • A random number, which will be used to generate the keys.

3. The server sends its certificate to the client.

4. The client authenticates the server by checking the validity of the server's certificate, the issuer CA, and optionally, by checking that the host name of the server matches the subject DN. The client sends a Session ID for session caching.

5. The client generates a random value ("pre-master secret"), encrypts it using the server's public key, and sends it to the server.

6. The server uses its private key to decrypt the message to retrieve the pre-master secret.

7. The client and server separately calculate the keys that will be used in the SSL session.

   These keys are not sent to each other because the keys are calculated based on the pre-master secret and the random numbers, which are known to each side. The keys include:

   • Encryption key that the client uses to encrypt data before sending it to the server

   • Encryption key that the server uses to encrypt data before sending it to the client

   • Key that the client uses to create a message digest of the data

   • Key that the server uses to create a message digest of the data

   The encryption keys are symmetric, that is, the same key is used to encrypt and decrypt the data.

8. The client and server send a Finished message to each other. These are the first messages that are sent using the keys generated in the previous step (the first "secure" messages).

   The Finished message includes all the previous handshake messages that each side sent. Each side verifies that the previous messages that it received match the messages included in the Finished message. This checks that the handshake messages were not tampered with.

9. The client and server now transfer data using the encryption and hashing keys and algorithms.

• SSL in the Oracle Fusion Middleware Architecture

• Keystores and Oracle Wallets

• Authentication Modes

• Tools for SSL Configuration

Description of "Figure 6-2 SSL in Oracle Fusion Middleware"

Notes:

• In Figure 6-2, the label "Oracle Enterprise Manager" refers to the Fusion Middleware Control user interface.

• Other administrative tools are available for specific tasks.

In the Oracle Fusion Middleware architecture shown in Figure 6-2, the numbered circles represent the endpoints that can be SSL-enabled. For configuration details about each endpoint, see:

1. Section 6.4.2.1, "Enable SSL for Inbound Requests to Oracle HTTP Server Virtual Hosts Using Fusion Middleware Control" and Section 6.4.2.2, "Enable SSL for Inbound Requests to Oracle HTTP Server Virtual Hosts Using WLST"

2. Section 6.4.2.3, "Enable SSL for Outbound Requests from Oracle HTTP Server"

3. Section 6.5.1.1, "Inbound SSL to Oracle WebLogic Server"

4. Outbound connections to the LDAP server can originate from Oracle Platform Security Services or from Oracle WebLogic Server:

   1. Section 6.5.1.2.1, "Outbound SSL from Oracle Platform Security Services to LDAP"

   2. Section 6.5.1.2.3, "Outbound SSL from LDAP Authenticator to LDAP"

8. Section 6.5.1.2, "Outbound SSL from Oracle WebLogic Server"

9. Section 6.6.1.1, "SSL-Enable Oracle Database"

Keystores and Wallets

Keystores and wallets are central to SSL configuration and are used to store certificates and keys.

For details, see Section 6.2.2, "Keystores and Oracle Wallets."

6.2.2 Keystores and Oracle Wallets

Oracle Fusion Middleware 12c (12.1.2) supports different types of keystores for keys and certificates:

• JKS-based keystore and truststore

  Oracle WebLogic Server uses JKS keystores in upgraded environments.

  JDK's keytool utility manages JKS keystores and certificates.

• Oracle wallet

  System components like Oracle HTTP Server use the Oracle wallet.

  Use Fusion Middleware Control, or the command-line WLST and orapki interfaces, to manage wallets and their certificates for system components. You can use either the Fusion Middleware Control or WLST to SSL-enable the listeners for these components.

• OPSS Keystore Service (KSS) keystore and truststore

  The Keystore Service provides an alternative mechanism to manage keys and certificates. Oracle WebLogic Server uses KSS keystores out-of-the-box in new 12c (12.1.2) installations.

  Use Fusion Middleware Control or WLST to manage KSS keystores and their certificates. Use the WebLogic console to SSL-enable the listeners for WebLogic servers.

For more information about these types of stores, and when to use which type of store, see Section 6.1.3, "Keystores and Wallets".

See Also:

Section 7.1, "Key and Certificate Storage in Oracle Fusion Middleware" for keystore management

6.2.3 Authentication Modes

The following authentication modes are supported:

• In no-authentication mode, neither server nor client are required to authenticate.

  Other names for this mode include Anonymous SSL/No Authentication/Diffie-Hellman. This mode is considered unsecured.

• In server authentication mode, a server authenticates itself to a client.

  This mode is also referred to as One-way SSL/Server Authentication.

• In mutual authentication mode, a client authenticates itself to a server and that server authenticates itself to the client.

  This mode is also known as Two-way SSL/Client Authentication.

• In optional client authentication mode, the server authenticates itself to the client, but the client may or may not authenticate itself to the server. Even if the client does not authenticate itself, the SSL session still goes through.

6.2.4 Tools for SSL Configuration

Oracle Fusion Middleware uses two kinds of configuration tools, common and advanced.

Common Tools

• Fusion Middleware Control

• WLST command-line interface

• Oracle WebLogic Server Administration Console

• keytool command-line tool

These tools allow you to configure SSL and manage Oracle Wallet/JKS keystore for any listener or component in Oracle Fusion Middleware.

The first three tools on this list are usable when the component is associated with the application server domain (when the component is not a stand-alone installation).

Advanced Tools

• orapki command-line interface

This tool is needed to manage wallets for certain stand-alone installations.

In addition, this tool allows you to configure advanced features like managing file-based CRLs, PKCS11-based wallets, and so on.

See Also:

Section 7.1, "Key and Certificate Storage in Oracle Fusion Middleware" for keystore management

6.3 Configuring SSL for Configuration Tools

Several tools are available for Oracle Fusion Middleware configuration. This section describes how to configure SSL for these tools to enable them to connect to an SSL-enabled Oracle WebLogic Server.

See Also:

Section 6.5.1.1 for details about enabling inbound SSL on Oracle WebLogic Server.

For a list of all the configuration tools, see Section 6.2.4, "Tools for SSL Configuration.".

This section contains these topics:

• Oracle Enterprise Manager Fusion Middleware Control

• Oracle WebLogic Server Administration Console

• WLST Command-Line Tool

6.3.1 Oracle Enterprise Manager Fusion Middleware Control

Take these steps:

• Ensure that the SSL port is enabled on the Oracle WebLogic Server instance on which Fusion Middleware Control is deployed, and that the browser (from which you will launch Fusion Middleware Control) trusts the server certificate.

• Now launch Fusion Middleware Control using an SSL-based URL, in the format https://host:port.

6.3.2 Oracle WebLogic Server Administration Console

Ensure that the SSL port is enabled on the Oracle WebLogic Server instance. Now launch the administration console by providing the SSL port in the URL. You may get a warning that the certificate is not trusted; accept this certificate and continue.

6.3.3 WLST Command-Line Tool

For details about configuring SSL for WLST, take these steps:

1. Launch the WLST shell.

2. Execute the WLST command:

   help('connect')
   

Follow the instructions described in the help text to set up the WLST shell in SSL mode.

See Also:

Section 6.9 for details about using WLST.

6.4 Configuring SSL for the Web Tier

This section contains these topics:

• Configuring Load Balancers

• Enabling SSL for Oracle HTTP Server Virtual Hosts

Note:

• This discussion applies to the Web Tier in the context of an Oracle WebLogic Server domain.

• The order in which these topics appear should not be confused with the sequence in which SSL is enabled (which varies depending on topology). Rather, they are arranged in order starting with the most front-ending component.

6.4.1 Configuring Load Balancers

Use the instructions specific to your load-balancing device to configure load balancers in your Oracle Fusion Middleware environment.

6.4.2 Enabling SSL for Oracle HTTP Server Virtual Hosts

This section shows how to manage SSL configuration for Oracle HTTP Server virtual hosts operating in an Oracle WebLogic Server environment.

Note:

For Oracle HTTP Server in standalone mode, see Administering Oracle HTTP Server.

For inbound traffic:

• Section 6.4.2.1 (using Fusion Middleware Control)

• Section 6.4.2.2 (using WLST)

For outbound traffic:

• Section 6.4.2.3 (using either Fusion Middleware Control or WLST)

6.4.2.1 Enable SSL for Inbound Requests to Oracle HTTP Server Virtual Hosts Using Fusion Middleware Control

You can SSL-enable inbound traffic to Oracle HTTP Server virtual hosts using these steps:

1. Select the Oracle HTTP Server instance in the navigation pane on the left.

2. Create a wallet, if necessary, by navigating to Oracle HTTP Server, then Security, then Wallets.

   For details about wallet creation and maintenance, see Chapter 7, "Managing Keystores, Wallets, and Certificates".

3. Navigate to Oracle HTTP Server, then Administration, then Virtual Hosts.

   This page shows what hosts are currently configured, and whether they are configured for http or https.

   
   Description of the illustration ohsssl1.gif
   
   

4. Select the virtual host you wish to update, and click Configure, then SSL Configuration. (Note: If creating a new virtual host, see Administering Oracle HTTP Server.)

   
   Description of the illustration ohsssl2.gif
   
   

   The SSL Configuration page appears.

5. You can convert an https port to http by simply unchecking Enable SSL.

   To configure SSL for a virtual host that is currently using http:

   • Check the Enable SSL box.

   • Select a wallet from the drop-down list.

     
     Description of the illustration ohsssl3.gif
     
     

   • From the Server SSL properties, select the SSL authentication type, cipher suites to use, and the SSL protocol version.

     Note:

     The default values are appropriate in most situations.

     Note:

     • This assumes that the certificate is available in Fusion Middleware Control. If it was created through orapki, import it first as explained in Section 7.4.4.9.

     • The choice of authentication type determines the available cipher suites, and the selected cipher suites determine the available protocol versions. For more information about ciphers and protocol versions, see Section 6.9.16.

6. Click OK to apply the changes.

7. On Windows platforms only, open Windows Explorer and navigate to your cwallet.sso file. Under properties, security, add SYSTEM in "group or user names".

8. Restart the Oracle HTTP Server instance by navigating to Oracle HTTP Server, then Control, then Restart.

9. Open a browser session and connect to the port number that was SSL-enabled.

6.4.2.2 Enable SSL for Inbound Requests to Oracle HTTP Server Virtual Hosts Using WLST

Take these steps:

1. Determine the virtual hosts for this Oracle HTTP Server instance by running the following command:

   listListeners('inst1','ohs1' )
   

   This command lists all the virtual hosts for this instance. Select the one that needs to be configured for SSL. For example, you can select vhost1. For details about this command, see WLST Command Reference for WebLogic Server.

2. Configure the virtual host with SSL properties:

   configureSSL('inst1',
      'ohs1',
      'ohs',
      'vhost1')
   

   Note:

   • configureSSL uses defaults for all SSL attributes; see Table 6-4 for details.

   • You could also specify a properties file as a parameter to configureSSL. See Table 6-3 for details about the parameters. See configureSSL in the WLST Command Reference for WebLogic Server for examples of how to use a properties file.

   • For details about this command, see Section 6.9.

3. On Windows platforms only, open Windows Explorer and navigate to your cwallet.sso file. Under properties, security, add SYSTEM in "group or user names".

6.4.2.3 Enable SSL for Outbound Requests from Oracle HTTP Server

You enable SSL for outbound requests from Oracle HTTP Server by configuring mod_wl_ohs.

One-way SSL

The steps are as follows:

1. Generate a custom keystore for Oracle WebLogic Server (see Section 6.5.1) containing a certificate.

2. Import the certificate used by Oracle WebLogic Server from Step 1 into the Oracle HTTP Server wallet as a trusted certificate. You can use any available utility such as WLST or Fusion Middleware Control for this task. (Note: The wallet mentioned here is the one that the Oracle HTTP Server listen port uses for SSL. The trusted (root) CA certificate that signed the Oracle WebLogic Server certificate must exist in this wallet. For details on importing trusted certificates see Section 7.4.7.5.)

3. Edit the Oracle HTTP Server configuration file DOMAIN_HOME/config/fmwconfig/components/OHS/instance_name/ssl.conf and add the following line to the SSL configuration under mod_weblogic:

   WlSSLWallet  "$(DOMAIN_HOME}/config/fmwconfig/components/COMPONENT_TYPE/COMPONENT_NAME/keystores/default"
   

   where default is the name of the Oracle HTTP Server wallet in Step 2.

   Here is an example of how the configuration should look:

   <IfModule mod_weblogic.c>
   WebLogicHost myweblogic.server.com
   WebLogicPort 7002
   MatchExpression *.jsp
   SecureProxy On
   WlSSLWallet "$(DOMAIN_HOME}/config/fmwconfig/components/OHS/ohs1/keystores/default"
   </IfModule>
   

   Save the file and exit.

4. On Windows platforms only, open Windows Explorer and navigate to your cwallet.sso file. Under properties, security, add SYSTEM in "group or user names".

5. Restart Oracle HTTP Server to activate the changes. See Administering Oracle HTTP Server for details.

6. Ensure that your Oracle WebLogic Server instance is configured to use the custom keystore generated in Step 1, and that the alias points to the alias value used in generating the certificate. Restart the Oracle WebLogic Server instance.

Two-way SSL

mod_wl_ohs also supports two-way SSL communication. To configure two-way SSL:

1. Perform Steps 1 through 4 of the preceding procedure for one-way SSL.

2. Generate a trust store, trust.jks, for Oracle WebLogic Server.

   The keystore created for one-way SSL (Step 1 of the preceding procedure) could also be used to store trusted certificates, but it is recommended that you create a separate truststore for this procedure.

3. Export the user certificate from the Oracle HTTP Server wallet, and import it into the truststore created in Step 2.

   You can use any available utility such as WLST or Fusion Middleware Control for export, and the keytool utility for import.

4. From the Oracle WebLogic Server Administration Console, select the Keystores tab for the server being configured.

5. Set the custom trust store with the trust.jks file location of the trust store that was created in Step 2 (use the full name).

6. Set the keystore type as JKS, and set the passphrase used to create the keystore.

7. Under the SSL tab, ensure that Trusted Certificate Authorities is set as from Custom Trust Keystore.

8. Ensure that Oracle WebLogic Server is configured for two-way SSL. For details, see "Configuring SSL" in Administering Security for Oracle WebLogic Server.

6.5 Configuring SSL for the Middle Tier

Using SSL in the middle tier includes:

• SSL-enabling the application server

• SSL-enabling components and applications running on the application server

This section addresses mid-tier SSL configuration and contains these topics:

• Configuring SSL for Oracle WebLogic Server

• Client-Side SSL for Applications

6.5.1 Configuring SSL for Oracle WebLogic Server

This section describes configuration for the application server.

6.5.1.1 Inbound SSL to Oracle WebLogic Server

For information and details about implementing SSL to secure Oracle WebLogic Server, see the following topics in Administering Security for Oracle WebLogic Server:

• "Configuring Oracle OPSS Keystore Service "

• "Configuring SSL"

6.5.1.2 Outbound SSL from Oracle WebLogic Server

This section describes how to SSL-enable outbound connections from Oracle WebLogic Server.

• Outbound SSL from Oracle Platform Security Services to LDAP

• Outbound SSL from Oracle Platform Security Services to Oracle Database

• Outbound SSL from LDAP Authenticator to LDAP

• Outbound SSL to Database

6.5.1.2.1 Outbound SSL from Oracle Platform Security Services to LDAP

This section explains how to configure SSL (needs server- and client-side) for policy store and credential store connections to an LDAP directory. It supports anonymous and one-way SSL.

See Securing Applications with Oracle Platform Security Services for details about the jps-config.xml file referenced in this section.

Anonymous SSL (Server-side)

Start the LDAP server in anonymous authentication mode.

Consult your LDAP server documentation for information on this task.

Anonymous SSL (Client-side)

In your jps-config.xml file, you must set the protocol to ldaps and specify the appropriate port for the property ldap.url. This information needs to be updated for policy store, credential store, key store and any other service instances that use ldap.url.

One-Way SSL (Client-side)

The following must be in place for the client-side configuration:

1. The JVM needs to know where to find the trust store that it uses to trust certificates from LDAP. You do this by setting:

   -Djavax.net.ssl.trustStore=path_to_jks_file
   

   This property is added either to the JavaSE program, or to the server start-up properties in a JavaEE environment.

2. In your jps-config.xml file, you must set the protocol to ldaps and specify the appropriate port for the property ldap.url. This information needs to be updated for policy store, credential store, key store and any other service instances that use ldap.url.

3. Using keytool, import the LDAP server's certificate into the trust store specified in step 1.

6.5.1.2.2 Outbound SSL from Oracle Platform Security Services to Oracle Database

You can set up a one-way or two-way SSL connection to a database-based OPSS security store.

For details about configuring the database server and clients, see Securing Applications with Oracle Platform Security Services.

6.5.1.2.3 Outbound SSL from LDAP Authenticator to LDAP

For details about outbound SSL to LDAP directories, see "How SSL Certificate Validation Works in WebLogic Server" in Administering Security for Oracle WebLogic Server.

6.5.1.2.4 Outbound SSL to Database

See "Configuring Secure Sockets Layer Authentication" in the Oracle Advanced Security Administrator's Guide at http://docs.oracle.com/cd/E11882_01/network.112/e10746/asossl.htm for more information about configuring SSL for the database listener.

6.5.2 Client-Side SSL for Applications

For information on how to write SSL-enabled applications, see "Using SSL Authentication in Java Clients" in Developing Applications with the WebLogic Security Service.

For best practices, refer to Section 6.8.2, "Best Practices for Application Developers."

6.6 Configuring SSL for the Data Tier

This section contains this topic:

• Configuring SSL for the Database

6.6.1 Configuring SSL for the Database

This section contains these topics:

• SSL-Enable Oracle Database

• SSL-Enable a Data Source

6.6.1.1 SSL-Enable Oracle Database

Take these steps to SSL-enable Oracle database:

1. Create a root CA and a certificate for the DB. Here is an example:

   Note:

   Self-signed certificates are not recommended for production use. For information about obtain production wallets, see Section 7.4.8.3, "Changing a Self-Signed Wallet to a Third-Party Wallet.".

   mkdir root
   mkdir server
    
   # Create root wallet, add self-signed certificate and export
   orapki wallet create -wallet ./root -pwd password
   orapki wallet add -wallet ./root -dn CN=root_test,C=US -keysize 2048 -self_signed -validity 3650 -pwd password
   orapki wallet display -wallet ./root -pwd password
   orapki wallet export -wallet ./root -dn CN=root_test,C=US -cert ./root/b64certificate.txt -pwd password
    
   #Create server wallet, add self-signed certificate and export
   orapki wallet create -wallet ./server -pwd password
   orapki wallet add -wallet ./server -dn CN=server_test,C=US -keysize 2048 -pwd password
   orapki wallet display -wallet ./server -pwd password
   orapki wallet export -wallet ./server -dn CN=server_test,C=US -request ./server/creq.txt -pwd password
    
   # Import trusted certificates
   orapki cert create -wallet ./root -request ./server/creq.txt -cert ./server/cert.txt -validity 3650 -pwd password
   orapki cert display -cert ./server/cert.txt -complete
   orapki wallet add -wallet ./server -trusted_cert -cert ./root/b64certificate.txt -pwd password
   orapki wallet add -wallet ./server -user_cert -cert ./server/cert.txt -pwd password
   orapki wallet create -wallet ./server -auto_login -pwd password}}
   

2. Update listener.ora, sqlnet.ora, and tnsnames.ora for the database.

   1. This example shows the default listener.ora:

      SID_LIST_LISTENER =
      (SID_LIST =(SID_DESC =(SID_NAME = PLSExtProc)(ORACLE_HOME = /path_to_O_H)(PROGRAM = extproc)))
      LISTENER =(DESCRIPTION_LIST =(DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = mynode.mycorp.com)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCPS)(HOST = mynode.mycorp.com)(PORT = 2490))
      ))
       
      WALLET_LOCATION=(SOURCE=(METHOD=FILE)(METHOD_DATA=(DIRECTORY=/wallet_location)))
       
      SSL_CLIENT_AUTHENTICATION=FALSE}}
      

      And here is an updated listener.ora file, illustrating a scenario with no client authentication:

      SID_LIST_LISTENER =
        (SID_LIST =
          (SID_DESC =
            (GLOBAL_DBNAME = dbname)
            (ORACLE_HOME = /path_to_O_H)
            (SID_NAME = sid)
          )
        )
       
      SSL_CLIENT_AUTHENTICATION = FALSE
       
      WALLET_LOCATION =
        (SOURCE =
          (METHOD = FILE)
          (METHOD_DATA =
            (DIRECTORY = /wallet_path)
          )
        )
       
      LISTENER =
        (DESCRIPTION_LIST =
          (DESCRIPTION =
            (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
          )
          (DESCRIPTION =
            (ADDRESS = (PROTOCOL = TCP)(HOST = mynode.mycorp.com)(PORT = 1521))
          )
          (DESCRIPTION =
            (ADDRESS = (PROTOCOL = TCPS)(HOST = mycorp.com)(PORT = 2490))
          )
        )
      

      Note that the SSL port has been added.

   2. Likewise, a modified sqlnet.ora file may look like this:

      NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
      SQLNET.AUTHENTICATION_SERVICES=(BEQ,TCPS,NTS)
      WALLET_LOCATION=(SOURCE=(METHOD=FILE)(METHOD_DATA=(DIRECTORY=/directory)))
      SSL_CLIENT_AUTHENTICATION=FALSE
      

   3. A modified tnsnames.ora file may look like this:

      OID =
        (DESCRIPTION =
          (ADDRESS = (PROTOCOL = TCP)(HOST = mynode.mycorp.com)(PORT = 1521))
          (CONNECT_DATA =
            (SERVER = DEDICATED)
            (SERVICE_NAME = mynode.mycorp.com)
          )
        )
         
      SSL =
        (DESCRIPTION =
          (ADDRESS_LIST =
            (ADDRESS = (PROTOCOL = TCPS)(HOST = mynode.mycorp.com)(PORT = 2490))
          )
          (CONNECT_DATA =
            (SERVICE_NAME = mynode.mycorp.com)
            or
            (SID = mynode.mycorp.com)
          )
          (SECURITY=(SSL_SERVER_CERT_DN=\"CN=server_test,C=US\"))
        )
      

3. Test the connection to the database using the new connect string. For example:

   $ tnsping ssl
   $ sqlplus username/password@ssl

The chapter "Configuring Secure Sockets Layer Authentication" in the Oracle Database Advanced Security Administrator's Guide.

6.6.1.2 SSL-Enable a Data Source

Take these steps to configure your data sources on Oracle WebLogic Server to use SSL.

1. Create a truststore and add the root certificate (which is created when SSL-enabling the database) as a trusted certificate to the truststore.

2. In the Oracle WebLogic Server Administration Console, navigate to the Connection pool tab of the data source that you are using.

   Note:

   The data source can be an existing source such as an Oracle WebCenter Portal data source, or a new data source. See Creating a JDBC Data Source in Administering JDBC Data Sources for Oracle WebLogic Server for details.

   The properties you need to specify in the JDBC Properties text box depend on the type of authentication you wish to configure.

   • If you will require client authentication (two-way authentication):

     javax.net.ssl.keyStore=..(password of the keystore)
            javax.net.ssl.keyStoreType=JKS
            javax.net.ssl.keyStorePassword=...(password of the keystore)
            javax.net.ssl.trustStore=...(the truststore location on the disk)
            javax.net.ssl.trustStoreType=JKS
            javax.net.ssl.trustStorePassword=...(password of the truststore)
     

   • If you will require no client authentication:

     javax.net.ssl.trustStore=...(the truststore location on the disk)
            javax.net.ssl.trustStoreType=JKS
            javax.net.ssl.trustStorePassword=...(password of the truststore)
     

3. In the URL text box, enter the JDBC connect string. Ensure that the protocol is TCPS and that SSL_SERVER_CERT_DN contains the full DN of the database certificate.

   Use the following syntax if tnsnames.ora uses "SERVICE_NAME":

   jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCPS)(HOST=host-name)(PORT=port-number)))(CONNECT_DATA=(SERVICE_NAME=service))(SECURITY=(SSL_SERVER_CERT_DN="CN=server_test,C=US")))
   

   Use the following syntax if tnsnames.ora uses "SID":

   jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCPS)(HOST=host-name)(PORT=port-number)))(CONNECT_DATA=(SID=service))(SECURITY=(SSL_SERVER_CERT_DN="CN=server_test,C=US")))
   

4. Test and verify the connection. Your data source is now configured to use SSL.

6.7 Advanced SSL Scenarios

This section explains how to handle additional SSL configuration scenarios beyond the basic topologies described earlier:

• Hardware Security Modules and Accelerators

• CRL Integration with SSL

• Oracle Fusion Middleware FIPS 140-2 Settings

For details and examples of the commands used in this section see Section 6.9.

6.7.1 Hardware Security Modules and Accelerators

A Hardware Security Module (HSM) is a physical plug-in card or an external security device that can be attached to a computer to provide secure storage and use of sensitive content.

Note:

This discussion applies only to Oracle HTTP Server, which is a system component supporting HSM.

Oracle Fusion Middleware supports PKCS#11-compliant HSM devices that provide a secure storage for private keys.

Take these steps to implement SSL for a component using a PKCS#11 wallet:

1. Install the HSM libraries on the machine where the component is running. This is a one-time task and is device-dependent.

2. Next, create a wallet using the orapki command-line tool. Note the following:

   1. Choose PKCS11 as the wallet type.

   2. Specify the device-specific PKCS#11 library used to communicate with the device. This library is part of the HSM software.

      On Linux, the library is located at:

      For LunaSA (Safenet):  /usr/lunasa/lib/libCryptoki2.so
      For nCipher:  /opt/nfast/toolkits/pkcs11/libcknfast.so
      

      On Windows, the library is located at:

      For LunaSA (Safenet): C:\Program Files\LunaSA\cryptoki.dll
      

3. Now follow the standard procedure for obtaining third-party certificates: create a certificate request; get the request approved by a Certificate Authority (CA); and install the certificate signed by that CA.

   The wallet you set up is used like any other wallet.

4. Verify the wallet with the orapki utility. Use the following command syntax:

   orapki wallet p11_verify [-wallet [wallet]] [-pwd password]
   

   See Also:

   Appendix G, "orapki" for details about orapki

5. Configure SSL on your component listener using the configureSSL WLST command, providing a properties file as input. Your properties file should specify the full path of the PKCS#11 wallet directory on the machine where the component is running. (Note: Do not save the PKCS#11 wallet in the instance home directory. Only wallets created and managed through Fusion Middleware Control or WLST should reside in the instance home.)

   A sample properties file could look like this:

   SSLEnabled=true
   AuthenticationType=Server
   PKCS11Wallet=/tmp/lunasa/wallet 
   

Note:

You must use the WLST command configureSSL to configure the PKCS11 wallet. You cannot do this task using Fusion Middleware Control or any other tool.

6.7.2 CRL Integration with SSL

Note:

• This discussion applies only to Oracle HTTP Server in the context of an Oracle WebLogic Server environment. For SSL configuration in standalone components, see Administering Oracle HTTP Server.

• Manage CRL validation through WLST. You cannot perform this task through Fusion Middleware Control.

Components that use SSL can optionally turn on certificate validation using a certificate revocation list (CRL). This allows them to validate the peer certificate in the SSL handshake and ensure that it is not on the list of revoked certificates issued by the Certificate Authority (CA).

This section describes how to configure a component to use CRL-based validation, and how to create and set up CRLs on the file system.

6.7.2.1 Configuring CRL Validation for a Component

Configure SSL on your component listener using the configureSSL WLST command, providing a properties file as input.

The properties file must be set up as follows:

1. The CertValidation attribute must be set to url.

2. The CertValidationPath attribute must be of the form file://file_path or dir://directory_path.

   • Use the first format if you are using a single CRL file for certificate validation. This CRL file should contain a concatenation of all CRLs.

   • Use the second format if you are specifying a directory path that contains multiple CRL files in hashed form.

     See Section 6.7.2.2, "Manage CRLs on the File System" on how to create CRLs in hashed form.

In this example, the properties file specifies a single CRL file:

SSLEnabled=true
AuthenticationType=Server
CertValidation=crl
KeyStore=ohs1 
CertValidationPath=file:///tmp/file.crl

In this example, the properties file specifies a directory path to multiple CRL files:

SSLEnabled=true
AuthenticationType=Server
KeyStore=ohs1 
CertValidation=crl
CertValidationPath=dir:///tmp

6.7.2.2 Manage CRLs on the File System

Note:

LDAP-based CRLs or CRL distribution points are not supported.

You use the orapki command-line tool to manage CRLs on the file system. For details on this topic, see Section G.1.5, "Managing Certificate Revocation Lists (CRLs) with orapki Utility."

CRL Renaming to Hashed Form

If specifying a CRL storage location, the CRL must be renamed. This enables CRLs to be loaded in an efficient manner at runtime. This operation creates a symbolic link to the actual CRL file. On Windows, it copies the CRL to a file with a new name.

To rename a CRL:

orapki crl hash 
[-crl [url|filename]] [-wallet wallet] [-symlink directory] 
[-copy directory] [-summary] [-pwd password]

For example:

orapki crl hash -crl nzcrl.txt -symlink wltdir -pwd password

If the CRL file name is specified at runtime, multiple CRLs can be concatenated in that file. The CRL created in this example is in Base64 format, and you can use a text editor to concatenate the CRLs.

CRL Creation

Note:

CRL creation and Certificate Revocation are for test purposes and only used in conjunction with self-signed certificates. For production use, obtain production certificates from well-known CAs and obtain the CRLs from those authorities.

To create a CRL:

orapki crl create 
[-crl [url|filename]] [-wallet [cawallet]] [-nextupdate [days]] [-pwd password]

For example:

orapki crl create 
-crl nzcrl.crl -wallet rootwlt -nextupdate 3650 -pwd password

Certificate Revocation

Revoking a certificate adds the certificate's serial number to the CRL.

To revoke a certificate:

orapki crl revoke 
[-crl [url|filename]] [-wallet [cawallet]] [-cert   [revokecert]] [-pwd password]

For example:

orapki crl revoke 
-crl nzcrl.txt -wallet rootwlt -cert cert.txt -pwd password

6.7.2.3 Test a Component Configured for CRL Validation

To test that a component is correctly configured for CRL validation, take these steps:

1. Set up a wallet with a certificate to be used in your component.

2. Generate a CRL with this certificate in the revoked certificates list. Follow the steps outlined in Section 6.7.2.2, "Manage CRLs on the File System."

3. Configure your component to use this CRL. Follow the steps outlined in Section 6.7.2.1, "Configuring CRL Validation for a Component."

4. The SSL handshake should fail when this revoked certificate is used.

6.7.3 Oracle Fusion Middleware FIPS 140-2 Settings

This section describes how to configure Oracle Fusion Middleware components to comply with the FIPS 140-2 advanced security standard. Topics include:

• FIPS-Configurable Products

• Setting the SSLFIPS_140 Parameter

• Selecting Cipher Suites

• Other Configuration Parameters

See Also:

For more information about this standard, refer to the Cryptographic Modules Validation Program Web site at:

http://csrc.nist.gov/groups/STM/index.html

6.7.3.1 FIPS-Configurable Products

Any product using the Oracle SSL SDK can be configured to run in the FIPS mode. Specifically, you can configure Oracle HTTP Server in FIPS mode.

6.7.3.2 Setting the SSLFIPS_140 Parameter

You can configure these components to run in the FIPS mode by setting the SSLFIPS_140 parameter to TRUE in the fips.ora file:

SSLFIPS_140=TRUE

This file does not exist out-of-the-box and has to be created. Locate fips.ora either in the $ORACLE_HOME/ldap/admin directory, or in the directory pointed to by the FIPS_HOME environment variable.

The SSLFIPS_140 parameter is set to FALSE by default. You must set it to TRUE for FIPS mode operation.

6.7.3.3 Selecting Cipher Suites

A cipher suite is a set of authentication, encryption, and data integrity algorithms used for exchanging messages between network nodes. During an SSL handshake, for example, the two nodes negotiate to see which cipher suite they will use when transmitting messages back and forth.

Only the following cipher suites are approved for use in FIPS mode:

SSL_RSA_WITH_3DES_EDE_CBC_SHA
SSL_DH_anon_WITH_3DES_EDE_CBC_SHA
TLS_RSA_WITH_AES_128_CBC_SHA
TLS_RSA_WITH_AES_256_CBC_SHA

Any other ciphers should not be used while running in FIPS mode.

You can configure one or more of these ciphers using comma-separated values. These should be specified in the SSL properties file for the key 'Ciphers' in the WLST configureSSL command, or through Fusion Middleware Control.

See Section 6.9.16, "Properties Files for SSL" for details about specifying the SSL properties file with the configureSSL command.

6.7.3.4 Other Configuration Parameters

The minimum key size for enabling FIPS mode is 1024 bits. You need to ensure that the keys used in FIPS mode are at least 1024 bits. This is because the certificate in the wallet used by components like Oracle HTTP Server must have a minimum public key size of 1024 bits.

You can only use wallets created using Oracle tools such as orapki. Third-party PKCS#12 wallet files cannot be used in FIPS mode.

6.8 Best Practices for SSL

This section outlines some best practices for Oracle Fusion Middleware component administrators and application developers. It contains these topics:

• Best Practices for Administrators

• Best Practices for Application Developers

6.8.1 Best Practices for Administrators

Best practices for system administrators include the following:

• Use self-signed wallets only in test environment. You should obtain a CA signed certificate in the wallet before moving to production environment. For details, see Chapter 7, "Managing Keystores, Wallets, and Certificates."

• It is recommended that components (at least in the Web tier) use certificates that have the system host name or virtual host or site name as the DN. This allows browsers to connect in SSL mode without giving unsettling warning messages.

• A minimum key size of 1024 bits is recommended for certificates used for SSL. Higher key size provides more security but at the cost of reduced performance. Pick an appropriate key size value depending on your security and performance requirements.

• Lack of trust is one of the most common reasons for SSL handshake failures. Ensure that the client trusts the server (by importing the server CA certificate into the client keystore) before starting SSL handshake. If client authentication is also required, then the reverse should also be true.

6.8.2 Best Practices for Application Developers

The following practices are recommended:

• Use Java Key Store (JKS) to store certificates for your Java EE applications.

• Externalize SSL configuration parameters like keystore path, truststore path, and authentication type in a configuration file, rather than embedding these values in the application code. This allows you the flexibility to change SSL configuration without having to change the application itself.

6.9 WLST Reference for SSL

WLST commands are available to manage Oracle wallets and to configure SSL for Oracle Fusion Middleware components.

Use the commands listed in Table 6-1 and Table 6-2 for this task.

See Also:

Section 7.2, "Command-Line Interface for Keystores and Wallets" for important instructions on how to launch the WLST shell to run SSL-related commands. Do not launch the WLST interface from any other location.

Note:

All WLST commands for SSL configuration must be run in online mode.

You can obtain help for each command by issuing:

help('command_name')

Certain commands require parameters like instance name, ias-component and process type. You can obtain this information with the command:

state('serverName') [in WebLogic domain]

nmServerStatus(serverName='name', serverType='type') [in Standalone domain]

6.9.16 Properties Files for SSL

SSL configuration employs certain properties files for use with the WLST configureSSL command. The files contain parameters to specify the desired SSL configuration, such as authentication type, cipher values, and SSL version.

You can use descriptive names if you need to manage multiple properties files for different components. For example, you could have properties files named ohs-ssl-properties.prop or ovd-ssl-properties.prop.

6.9.16.1 Structure of Properties Files

All the SSL properties files have a consistent structure.

Table 6-3 provides details about the key-value structure and usage of these files.

Table 6-3 Parameters in Properties File

Key	Mandatory?	Allowed Values for Oracle HTTP Server	Usage
SSLEnabled	No	true false	Either value
Ciphers	No	See "SSLCipherSuite" in Administering Oracle HTTP Server.	One or more comma separated values
SSLVersions	No	See "SSLProtocol" in Administering Oracle HTTP Server.	One or more comma separated values
CertValidation	No	none crl	Either value
CertValidation Path	No	file://crl_file_path dir://crl_dir_path	Path of the CRL file, or directory containing CRL files
KeyStore	No	Valid wallet name
TrustStore	No	N/A
AuthenticationType	No	None Server Optional Mutual	Any one value

Table 6-4 shows the default values:

Table 6-4 Default Values of Parameters

Key	Default Value for Oracle HTTP Server
SSLEnabled	true
Ciphers	null
SSLVersions	null
CertValidation	none
CertValidation Path	null
KeyStore	default
TrustStore	-
Authentication Type	Server

Note:

• At least one DH_anon cipher must be used in SSL no-auth mode. For all other modes, at least one RSA cipher must be used.

• The value of the KeyStore parameter must be specified when configuring SSL in server-auth, mutual-auth, or optional client auth.

• If only AES ciphers have been specified, the SSLVersions parameter must contain TLSv1 or nzos_Version_1_0.

• If you are doing CRL-based validation, the value of the CertValidation parameter should be crl and the value of the CertValidationPath parameter should point to the CRL file/directory.

6.9.16.2 Examples of Properties Files

Some examples demonstrating the use of the properties files follow.

Example 1: Basic Properties File

SSLEnabled=true
AuthenticationType=None
CertValidation=none

This properties file specifies no authentication mode, and default values will be used during SSL configuration for ciphers and SSL version. Keystore and truststore properties are not specified since the authentication type is None. For other authentication types, keystore must be specified.

Example 2: Basic Properties File

SSLEnabled=
AuthenticationType=None
CertValidation=none

This properties file is exactly the same as above, except that SSLEnabled is explicitly specified without any value. This is the same as not specifying the key at all. In both cases, the default value will be used.

Therefore, all the following three settings have the same meaning:

• The setting:

  SSLEnabled=true
  

  Here the value true is explicitly specified.

• The setting:

  SSLEnabled=
  

  Since no value is mentioned here, the default value of SSLEnabled (true) is used.

• The key SSLEnabled is not present in the properties file.

  Since the key is not present, its default value (true) is used.

Example 3: Properties File with Version for OHS

SSLEnabled=true
AuthenticationType=Mutual
SSLVersion=nzos_Version_1_0
CertValidation=crl
CertValidationPath=file:///tmp/file.crl
KeyStore=ohs1

This properties file has:

• Default values for ciphers

• Keystore

• SSL version v1

• CRL validation turned on

• Mutual Authentication mode
