📡 Detection & Monitoring

Log Indicators:

  • Unexpected file modification events in configuration directories
  • Failed file permission errors
  • Application restart logs without authorized changes

Network Indicators:

  • Unusual network connections to configuration management ports
  • Unexpected file transfer patterns

SIEM Query:

file_modification AND (path:"*/config/*" OR path:"*.conf" OR path:"*.ini") AND NOT user:authorized_user
