Description
The unauthorized-access-log documents any login attempt that fails due to incorrect credentials, expired accounts, or security policy violations (e.g., IP bans, MFA failure). This log is crucial for detecting brute-force attacks, insider threats, or users unknowingly using outdated credentials.
It typically includes the attempted username, source IP address, timestamp, service being accessed, and failure reason. In advanced setups, the log may also capture user agent strings or geolocation info, which can help identify suspicious patterns.
These logs are often tied into automatic protection tools like Fail2Ban or firewalls that temporarily block IPs after multiple failed attempts. They also feed into incident detection platforms for behavioral analysis (e.g., “User X failed to log in 12 times from three countries in one hour”).
Over time, these logs help harden services by revealing which endpoints are frequently targeted, which usernames attackers are guessing, or which timeframes see spikes in attempts.
