Chapter 21. Using the Automated Security Enhancement Tool (ASET)

The automated security enhancement tool (ASET) enables you to monitor and control system security by automatically performing tasks that you would otherwise do manually.

ASET consists of seven tasks, each performing specific checks and adjustments to file systems.

• System files permissions verification.

• System files checks.

• User/group checks.

• System configuration files check.

• Environment check.

• eeprom check.

• Firewall setup.

The ASET tasks tighten file permissions, check the contents of critical system files for security weaknesses, and monitor crucial areas. ASET can contribute to safeguarding a network by applying the basic requirements of a firewall system to a system that serves as a gateway system.

Each task generates a report noting detected security weaknesses and changes the task has made to the system files. When run at the highest security level, ASET tries to modify all system security weaknesses. If it cannot correct a potential security problem, ASET reports the existence of the problem.
