Post-Install Configuration Tasks

4.1 Audit Vault Server Post-Installation Tasks

Complete these recommended post-installation tasks after installing the Audit Vault Server.

Complete the steps in section Accessing the Audit Vault Server Post-Install Configuration Page and set up user names and passwords.
Apply the patch to remove deprecated ciphers after an Audit Vault Server install or upgrade: Deprecated-Cipher-Removal.zip.

Note:

Apply this patch on Oracle Audit Vault Server 20.1 after an install or upgrade. For an upgrade, before applying the patch, make sure that all Audit Vault Agents are upgraded to 20.1 and Host Monitor Agents are in the Installed state.
Review the DNS and NTP system service configuration. See Configuring or Changing the Oracle Audit Vault Server Services.
If using high availability, configure resilient pair of Audit Vault Servers. See Configuring High Availability for Audit Vault Servers.
Register the targets for monitoring with Oracle Audit Vault and Database Firewall. See Configuring Targets, Audit Trails, and Database Firewall Monitoring Points.
Configure the data retention policy for every target before configuring audit trails. See Configuring Archive Locations and Retention Policies.
Configure each audit trail for native audit collection. See Preparing Targets for Audit Data Collection.
1. Deploy an Audit Vault Agent on the machine where the target is installed or on a machine that can connect to the target.
  
  Note:
  Starting in Oracle AVDF 20.9, you can use agentless collection instead of the Audit Vault Agent for up to 20 Oracle Database table audit trails. Starting in Oracle AVDF 20.10, you can also use agentless collection for Microsoft SQL Server directory audit trails for .sqlaudit and .xel (extended events). The total number of audit trails for agentless collection should not exceed 20. See Adding Audit Trails with Agentless Collection.
2. Enable native database auditing on the target.
3. Review and configure the audit trails for the target.
4. Configure the audit trail cleanup wherever necessary.
For Oracle Database targets, consider provisioning Oracle recommended audit policies. See Creating Audit Policies for Oracle Databases.
Consider configuring alert policies. See Creating Alerts.

Note:

The Audit Vault Server reads the audit log from the target that contains the time stamp of the event. Without this synchronization, events may appear to be archived to the Audit Vault Server before they occur and alerts may appear to be sent before their triggering events occur.
Set the user names and passwords of the Audit Vault Server administrator and auditor, as well as the passwords of its root and support users. You can also set the time and domain name service (DNS) servers of the Audit Vault Server.

4.2 Database Firewall Post-Installation Tasks

Learn about Database Firewall post-installation tasks.

After installing the Database Firewall, set the password for support user. This is the Linux operating system user account on Database Firewall. Follow these steps to set the password:

Execute the following command to set the password for the support user:
```
passwd support
```
Enter the new password for the support user when prompted.

4.3 Accessing the Audit Vault Server Post-Install Configuration Page

Access the Audit Vault Server post-installation configuration page.

To access the Audit Vault Server Post-Install Configuration page:

Using a browser, go to the Audit Vault Server console. Ensure that the browser version you are using supports TLS 1.2 protocol. See Supported Browsers for complete information.
```
https://ip_address
```
For ip_address, use the IP address of the Audit Vault Server. See Installing Audit Vault Server or Database Firewall.

You may see a message about a problem with the website security certificate. This is due to a self-signed certificate. Click the Continue to this website (or similar) link. You can generate a certificate request later to avoid this message. This is one of the possible reasons. However, there may be other reasons where the browser may prompt about the website being insecure. Use your due caution, verify, and then connect to the correct website.

See Oracle Audit Vault and Database Firewall Administrator's Guide.
You are prompted to enter the root password.
Click Login. The post-install configuration page appears.

The administrator and auditor user names must follow these rules:

The first character has to be alphabetical.
1 to 30 characters long.
Each remaining character is either alphanumeric or an underscore (_), dollar sign ($), or number sign (#).

Note:

The administrator and auditor user names are upshifted (that is, any lowercase alphabetic characters are replaced by their uppercase equivalents). Also, the Audit Vault Server does not support quoted user names.

See Also:

Separation of Duties for a description of each user account.

4.4.2 Password Requirements

Set password management guidelines for the Audit Vault and Database Firewall (Oracle AVDF) user accounts.

For example, you may require that users change their passwords on a regular basis, such as every 120 days, and that they create passwords that are not easily guessed.

The following sections describe the minimum password requirements for Oracle Audit Vault and Database Firewall.

Requirements for Passwords Containing Unicode Characters

If your password contains unicode characters (such as non-English characters with accent marks), the password requirement is that it:

Be between 8 and 30 characters long.
