AUDIT_USER(5) File Formats Manual AUDIT_USER(5) NAME audit_user -- events to be audited for given users DESCRIPTION The audit_user file specifies which audit event classes are to be audited for the given users. If specified, these flags are combined with the sys- tem-wide audit flags in the audit_control(5) file to determine which classes of events to audit for that user. These settings take effect when the user logs in. Each line maps a user name to a list of classes that should be audited and a list of classes that should not be audited. Entries are of the form: username:alwaysaudit:neveraudit In the format above, alwaysaudit is a set of event classes that are always audited, and neveraudit is a set of event classes that should not be au- dited. These sets can indicate the inclusion or exclusion of multiple classes, and whether to audit successful or failed events. See audit_con- trol(5) for more information about audit flags. Example entries in this file are: root:lo,ad:no jdoe:-fc,ad:+fw These settings would cause login/logout and administrative events that are performed on behalf of user "root" to be audited. No failure events are audited. For the user "jdoe", failed file creation events are audited, ad- ministrative events are audited, and successful file write events are never audited. IMPLEMENTATION NOTES Per-user and global audit preselection configuration are evaluated at time of login, so users must log out and back in again for audit changes relat- ing to preselection to take effect. Audit record preselection occurs with respect to the audit identifier asso- ciated with a process, rather than with respect to the UNIX user or group ID. The audit identifier is set as part of the user credential context as part of login, and typically does not change as a result of running setuid or setgid applications, such as su(1). This has the advantage that events that occur after running su(1) can be audited to the original authenticated user, as required by CAPP, but may be surprising if not expected.

It was subsequently adopted by the TrustedBSD Project as the foundation for the OpenBSM distribution.
