TMA-AIX-2.2
Ensure Trusted Execution Path is enabled
Deskripsi
The recommendation is to activate TE to enhance system integrity by specifying authorized locations for applications to hamper attacks from unauthorized locations using Trojan horse style tactics. TE provides a robust system integrity checking process. Hackers utilize any opening they can find to infiltrate a system. One common attack pattern includes getting an unauthorized program (aka Trojan horse) installed anywhere on the target system. Audit: trustchk -p TE TEP must report TE=ON and TEP=ON (review the TEP path list manually).
Cara pemeriksaan
Metode audit: Perintah shell
command -v trustchk >/dev/null 2>&1 || exit 1; out=$(trustchk -p TE TEP 2>/dev/null) || exit 1; r=compliant; for p in '^TE=ON$' '^TEP=ON$'; do printf '%s\n' "$out" | grep -Eq -- "$p" || r="missing: $p"; done; echo "$r"- Output yang diharapkan

NOTE: Your configuration of TE is dependent on the unique requirements of your environment. To configure TE to enforce a Trusted Execution Path (TEP) you need to know the intended secure path. e.g., SecurePath="/usr/bin:/usr/sbin" Perform the following: # First disable both TE and TEP trustchk -p TE=OFF TEP=OFF # Set the secure TEP variable trustchk -p TEP=${SecurePath} # Enable TE and TEP trustchk -p TE=ON TEP=ON Further details regarding planning and implementation of TE can be found within the IBM AIX 7 Infocentre: https://www.ibm.com/docs/en/aix/7.3?topic=configuration-trusted-execution
