Ensure modification to TE system is audited

SrednjaNivo 1Automatskaaix

Opis

At Level 1, Trusted Execution (TE) should be actively monitoring for applications not yet allowlisted. The recommendation for this is in section two. Additionally, the AIX AUDIT system needs to be configured for modifications to the TE subsystem. Modification to security mechanisms need to be monitored to maintain system integrity. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

Kako se proverava

Metod provere: Komanda ljuske

shell

out=$(grep -E "^[[:blank:]]*default[[:blank:]]*=" /etc/security/audit/config 2>/dev/null) || exit 1; r=compliant; for p in '(=|,)[[:blank:]]*TE_Untrusted([[:blank:]]*,|[[:blank:]]*$)' '(=|,)[[:blank:]]*TE_FileWrite([[:blank:]]*,|[[:blank:]]*$)' '(=|,)[[:blank:]]*TE_Policies([[:blank:]]*,|[[:blank:]]*$)' '(=|,)[[:blank:]]*TEAdd_Stnz([[:blank:]]*,|[[:blank:]]*$)' '(=|,)[[:blank:]]*TEDel_Stnz([[:blank:]]*,|[[:blank:]]*$)' '(=|,)[[:blank:]]*TESwitch_algo([[:blank:]]*,|[[:blank:]]*$)' '(=|,)[[:blank:]]*TEQuery_Stnz([[:blank:]]*,|[[:blank:]]*$)'; do printf '%s\n' "$out" | grep -Eq -- "$p" || r="missing: $p"; done; echo "$r"

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

Ensure AUDIT Trusted Execution events are in the class default. 1. Edit the file /etc/security/audit/config 2. Find the stanza named classes: 3. If the class default does not exist add a line with: default = TE_Untrusted,TE_FileWrite,TE_Policies,TEAdd_Stnz,TEDel_Stnz,TESwitch_algo,TEQ uery_Stnz 4. If the class default already exists ensure the following audit events are included in the class definition TE_Untrusted,TE_FileWrite,TE_Policies,TEAdd_Stnz,TEDel_Stnz,TESwitch_algo,TEQ uery_Stnz
