SRG-APP-000099-NDM-000229
Group -
The Cisco ASA must be configured to produce audit records that contain information to establish the outcome of the event.
Without information about the outcome of events, security personnel cannot make an accurate assessment as to whether an attack was successful or if changes were made to the security state of the sy...Rule Medium Severity -
SRG-APP-000101-NDM-000231
Group -
The Cisco ASA must be configured to generate audit records containing the full-text recording of privileged commands.
