9. Auditing

Auditing is one of the more overlooked security features in the Solaris OS. It gives you the ability to collect data about security-related system events. The data is used for accountability purposes, and is used to assign responsibility for actions that take place on a host.

Auditing has been a security feature since SunOS 3.5e, and the current implementation has been in the Solaris OS since version 2.3. However, recent regulatory requirements, such as SOX (Sarbanes-Oxley Act) and HIPAA (Health Insurance Portability and Accountability Act), which require that all activity on the systems be attributed to the users, have highlighted the necessity of auditing.
