Administrators can use the security log to help identify any potential unauthorized access to the system. The security log is configured with the parameter icm/security_log.

The following irregularities are logged:

  • Data with invalid syntax

  • Attempted access to objects that do not exist (NOT found)

  • Access to objects that is not permitted due to filter rules (permission denied)

  • Logon errors to Web administration (in ICM and Web Dispatcher)

Examples of Log Entries
  • Error: Permission denied (-13), authorization failed for user >sap< [http_auth_mt.c 745]

  • Error: Protocol error (-21), illegal request version: 1009

  • Error: Protocol error (-21), NULL bytes in HTTP request [http_plg_mt.c 4037]

Depending on the configuration the data that gave rise to the log entry is also output:

Note Note

The security log gives an indication of the possible security procedures that could be followed. In particular cases a decision must be made as to whether the entry really is a serious security risk.

End of the note.
