C2 auditing in the X Display Manager

This paper describes the implementation of C2 auditing in the MIT X Consortium X Display Manager (XDM) on a Sun Workstation. This custom implementation of XDM audits user logins, attempted logins and logouts by creating a C2 audit trail in the workstation's audit file. Additionally, when a user has exceeded a specified number of failed login attempts, the user's account and/or workstation may be disabled.<
