𝗤𝘂𝗶𝗰𝗸 𝗜𝗻𝘀𝗶𝗴𝗵𝘁:
Audit logs are critical for detection, investigation, and compliance.
But in many environments, the same administrators being logged are also able to 𝘃𝗶𝗲𝘄, 𝗺𝗼𝗱𝗶𝗳𝘆, 𝗼𝗿 𝗱𝗲𝗹𝗲𝘁𝗲 𝘁𝗵𝗼𝘀𝗲 𝗹𝗼𝗴𝘀.

When log integrity isn’t protected, forensic truth becomes negotiable.

Common audit log governance risks include:

• Admins with permission to delete or truncate logs 🔑
• Log storage located on the same systems being monitored 🕳️
• No immutability or write-once protections ⚠️
• Lack of separation between system admins and log administrators
• Log retention shortened for “storage optimization” reasons
• No alerting when logging is disabled or altered

⚠️ If attackers gain admin rights and can alter logs, detection becomes optional — and attribution becomes impossible.

𝗔𝘂𝗱𝗶𝘁 𝗧𝗶𝗽:
📜 During SOC, infrastructure, and governance audits, validate:

• Logs are stored in 𝗰𝗲𝗻𝘁𝗿𝗮𝗹𝗶𝘇𝗲𝗱, 𝗶𝗺𝗺𝘂𝘁𝗮𝗯𝗹𝗲 𝗿𝗲𝗽𝗼𝘀𝗶𝘁𝗼𝗿𝗶𝗲𝘀
• Administrative access to logs follows 𝘀𝘁𝗿𝗶𝗰𝘁 𝘀𝗲𝗽𝗮𝗿𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝗱𝘂𝘁𝗶𝗲𝘀
• Log deletion, truncation, or configuration changes are logged and alerted
• Retention policies align with forensic and regulatory requirements
• Backup copies of critical logs are protected separately
• Logging systems themselves are monitored for tampering

𝗔𝗰𝘁𝗶𝗼𝗻𝗮𝗯𝗹𝗲 𝗥𝗲𝗺𝗶𝗻𝗱𝗲𝗿:
Ask your SOC or infrastructure team:

• Who can delete or modify audit logs today?
• Are logs protected from the same admins they monitor?
• Would we detect if logging were disabled during an attack?
• Can we guarantee forensic integrity during an investigation?

If logs can be altered by those they observe, trust in your detection pipeline collapses.
