TMA-AIX-2.5

Ensure Allowlist violations are enabled

MediaNivel 2Automatizadaaix

Descripción

This takes allowlist aka whitelisting to the next level - where all software, libraries and scripts that are not in the trusted signature database (TSD) in /etc/security/tsd/tsd.dat are blocked. Trusted Execution (TE) provides an additional layer of access controls to processes on top of the base Discretionary Access Controls. Monitoring how processes access system resources can improve awareness of system integrity. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
