audit_get_session - Linux

Overview

audit_get_session retrieves the current audit session ID. This is a unique identifier for a set of audit events generated within a specific context or timeframe.

Syntax

audit_get_session [options]

Options/Flags

  • -w: Wait for a session to become active.

Examples

Get the current audit session ID:

$ audit_get_session
3025

Wait for a session to become active:

$ audit_get_session -w
3042

Common Issues

  • If no session ID is available, the command exits with an error message.
  • The -w flag may block indefinitely if no session becomes active.

Integration

audit_get_session can be used with other audit commands to manage audit events. For example:

# Get the session ID
session_id=$(audit_get_session)

# Enable auditing for a specific session
auditctl -a exit,always -S $session_id

# Print all events in the session
ausearch -k $session_id
