The sybsecurity device is created as part of the auditing installation process. The sybsecurity device stores the sybsecurity database and the auditing system procedures with which you can configure auditing for your system.
The auditing system records system security information in an Adaptive Server audit trail. You can use this audit trail to monitor the use of Adaptive Server or system resources.
For information about installing and using the auditing system, see Auditing in the System Administration Guide: Volume 1.
