About:
AIDE (Advanced Intrusion Detection Environment) is a file and directory integrity checker that creates a database of file checksums and metadata. It periodically compares the current state of the filesystem against this baseline to detect unauthorized modifications, deletions, or additions. This tool is essential for security auditing and monitoring critical system files for changes.
Key Features:
  • Supports multiple strong hash algorithms including SHA256, SHA512, and MD5
  • Can detect changes in file permissions, ownership, and timestamps
  • Database can be stored securely and compared from a read-only medium
  • Flexible configuration allows for selective monitoring of directories
  • Supports compression of the integrity database
Use Cases:
  • Monitoring critical system files and binaries for rootkits or unauthorized changes
  • Verifying the integrity of web server content and application files
  • Compliance auditing for security standards that require file integrity monitoring
Alternatives:
  • Tripwire – Tripwire is another industry-standard FIM tool, but AIDE is open-source and often considered easier to configure for basic use cases.
  • OSSEC – OSSEC is a host-based intrusion detection system (HIDS) that includes log analysis and rootkit detection in addition to file integrity monitoring.
