Security virtual machine for advanced auditing

摘要

A security system collects an audit trail on a computer outside of a boundary created by one or more virtual machines. The security system uses a privileged virtual machine to collect audit logs for each protected virtual machine. As the protected virtual machines run, they send auditing information to the privileged virtual machine. The privileged virtual machine can collect auditing information from protected virtual machines much more quickly than a network server, as well as collecting auditing events from multiple protected virtual machines. Because the auditing destination is located on the same computer as the virtual machine monitored by the audit trail, no network dependency is present. Thus, the security system allows for monitoring the activity of administrators and other users while preventing tampering with the audit trail of each user's actions.
