How to Add an Audit Class

Language:

When you create your own audit class, you can place into it just those audit events that you want to audit for your site. This strategy can reduce the number of records that are collected and reduce noise in your audit trail.

When you add the class on one system, copy the change to all systems that are being audited. Best practice is to create audit classes before the first users log in.

For information about the effects of modifying an audit configuration file, see Audit Configuration Files and Packaging.

Tip - In Oracle Solaris you can create your own package that contains files and replace the Oracle Solaris packages with your site-customized files. When you set the preserve attribute to true in your package, the pkg subcommands, such as verify, fix, revert, and so on, will run relative to your packages. For more information, see the pkg(1) and pkg(5) man pages.

Before You Begin

Choose free bits for your unique entry. Verify which bits are available for customer use in the /etc/security/audit_class file.

You must become an administrator who is assigned the solaris.admin.edit/etc/security/audit_class authorization. By default, only the root role has this authorization. For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2.

(Optional) Save a backup copy of the audit_class file.

# cp /etc/security/audit_class /etc/security/audit_class.orig

Add new entries to the audit_class file.
Each entry has the following format:
```
0x64bitnumber:flag:description
```
For a description of the fields, see the audit_class (4) man page. For the list of existing classes, read the /etc/security/audit_class file.

Example 3-15 Creating a New Audit Class

This example creates a class to hold administrative commands that are executed in a role. The added entry to the audit_class file is as follows:

0x0100000000000000:pf:profile command

The entry creates the new pf audit class. Example 3–16 shows how to populate the new audit class.

Troubleshooting

If you have customized the audit_class file, make sure that any audit flags that are assigned directly to users or rights profiles are consistent with the new audit classes. Errors occur when an audit_flags value is not a subset of the audit_class file.
