The cryptographic libraries for SSL included in Oracle Database 10g are designed to meet FIPS 140-2 Level 2 certification. Oracle Advanced Security makes use of these cryptographic libraries for SSL authentication. Please verify the current status of the certification at the Cryptographic Modules Validation Program Web site address:
The security policy, which would be available at the NIST site upon successful certification, includes requirements for secure configuration of the host operating system.
The following topics are covered in this appendix:
Oracle Advanced Security SSL adapter can be configured to run in FIPS mode by setting the
SSLFIPS_140 parameter to
TRUE in the
This parameter is set to
FALSE by default. It must be set to
TRUE on both the client and the server for FIPS mode operation.
Make sure that the
fips.ora file is either located in the
/ldap/admin directory, or is pointed to by the
FIPS_HOME environment variable. This procedure can be repeated in any Oracle home for any database server or client.
SSLFIPS_140parameter replaces the
SQLNET.SSLFIPS_140parameter used in Oracle Database 10g Release 2 (10.2). The parameter needs to be set in the
fips.orafile, and not the
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 as to which cipher suite they will use when transmitting messages back and forth.
Only the following cipher suites are approved for FIPS validation:
Oracle Advanced Security SSL cipher suites are automatically set to FIPS approved cipher suites. If you wish to configure specific cipher suites, you can do so by editing the
SSL_CIPHER_SUITES parameter in the
sqlnet.ora or the
You can also use Oracle Net Manager to set this parameter on the server and the client.
See Also:"Step 2C: Set the Secure Sockets Layer Cipher Suites on the Server (Optional)" and "Step 3D: Set the Client Secure Sockets Layer Cipher Suites (Optional)" for more information on setting cipher suites.
After installation, the following permissions must be verified in the operating system:
Execute permissions must be set on all Oracle executable files so as to prevent execution of Oracle Cryptographic Libraries by users who are unauthorized to do so in accordance with the system security policy.
Read and write permissions must be set on all Oracle executable files so as to prevent accidental or deliberate reading or modification of Oracle Cryptographic Libraries by any user.
To comply with FIPS 140-2 Level 2 requirements, the security policy must include procedures to prevent unauthorized users from reading, modifying or executing Oracle Cryptographic Libraries processes and the memory they are using in the operating system.
To check if FIPS mode is enabled, tracing can be added to the
sqlnet.ora file. FIPS self-test messages can be found in the trace file. Add the following lines to
sqlnet.ora to enable tracing:
trace_directory_server=trace_dir trace_file_server=trace_file trace_level_server=trace_level
trace_directory=/private/oracle/owm trace_file_server=fips_trace.trc trace_level_server=6
Trace level 6 is the minimum trace level required to check the results of the FIPS self-tests.
