  script_tag(name:"summary", value:"Audit Other Logon/Logoff Events determines whether Windows
generates audit events for other logon or logoff events.

These other logon or logoff events include:

  - A Remote Desktop session connects or disconnects.

  - A workstation is locked or unlocked.

  - A screen saver is invoked or dismissed.

  - A replay attack is detected. This event indicates that a Kerberos request was received twice with
identical information. This condition could also be caused by network misconfiguration.

  - A user is granted access to a wireless network. It can be either a user account or the computer
account.

  - A user is granted access to a wired 802.1x network. It can be either a user account or the
computer account.

Logon events are essential to understanding user activity and detecting potential attacks.
