TACACS (Terminal Access Controller Access-Control System) authentication is a protocol used in IBM QRadar SIEM V7.5 for authenticating users by forwarding their credentials to an external server. Here's how it works:

Encryption: TACACS encrypts the entire payload of the authentication packet, including the username and password, ensuring secure transmission.

Forwarding Credentials: After encryption, the credentials are forwarded to an external TACACS server, which performs the actual authentication.

Authentication Process: The external server checks the credentials against its database and sends a response back to QRadar indicating whether the authentication is successful or not.

Reference IBM QRadar SIEM documentation explains TACACS authentication in detail, highlighting its secure encryption and external server verification process.

Impact: If this limit is reached, QRadar will not generate new offenses until some of the existing offenses are closed or archived.

Configuration: Administrators can adjust this setting based on their organizational needs, but the default value is 2500.

Reference This information is detailed in the QRadar SIEM configuration and tuning guides, which specify default settings and provide instructions for modifying the maximum number of active offenses if necessary.
