T1070.002 Clear Linux or Mac System Logs Mappings

Adversaries may clear system logs to hide evidence of an intrusion. macOS and Linux both keep track of system or user-initiated actions via system logs. The majority of native system logging is stored under the <code>/var/log/</code> directory. Subfolders in this directory categorize logs by their related functions, such as:(Citation: Linux Logs)

  • <code>/var/log/messages:</code>: General and system-related messages
  • <code>/var/log/secure</code> or <code>/var/log/auth.log</code>: Authentication logs
  • <code>/var/log/utmp</code> or <code>/var/log/wtmp</code>: Login records
  • <code>/var/log/kern.log</code>: Kernel logs
  • <code>/var/log/cron.log</code>: Crond logs
  • <code>/var/log/maillog</code>: Mail server logs
  • <code>/var/log/httpd/</code>: Web server access and error logs

Comments
The Amazon Inspector Best Practices assessment package can assess security control "Configure permissions for system directories" that prevents privilege escalation by local users and ensures only the root account can modify/execute system configuration information and binaries. Amazon Inspector does not directly protect against system modifications rather it just checks to see if security controls are in place which can inform decisions around hardening the system. Due to this and the fact the security control is only supported for Linux platforms, the score is Minimal.
