SRG-NET-000075-IDPS-00060
Group -
The Cisco ASA must be configured to produce audit records containing information to establish when the events occurred.
Without establishing the time (date/time) an event occurred, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack. Associating the date and ti...Rule Medium Severity -
SRG-NET-000076-IDPS-00061
Group -
The Cisco ASA must be configured to produce audit records containing information to establish where the event was detected.
Associating where the event was detected with the event log entries provides a means of investigating an attack or identifying an improperly configured IDPS. This information can be used to determi...Rule Medium Severity -
SRG-NET-000077-IDPS-00062
Group -
The Cisco ASA must be configured to produce audit records containing information to establish the source of the event.
Associating the source of the event with detected events in the logs provides a means of investigating an attack or suspected attack. While auditing and logging are closely related, they are not t...Rule Medium Severity -
SRG-NET-000078-IDPS-00063
Group -
The Cisco ASA must be configured to produce audit records containing information to establish the outcome of events associated with detected harmful or potentially harmful traffic.
Associating event outcome with detected events in the log provides a means of investigating an attack or suspected attack. While auditing and logging are closely related, they are not the same. Lo...Rule Medium Severity -
SRG-NET-000113-IDPS-00013
Group -
The Cisco ASA must be configured to log events based on policy access control rules, signatures, and anomaly analysis.
Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident, or identify those responsible for one. While au...Rule Medium Severity -
SRG-NET-000334-IDPS-00191
Group -
The Cisco ASA must be configured to off-load log records to a centralized log server.
Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading ensures audit information does not get overwritten if the limited audit storage capa...Rule Medium Severity -
SRG-NET-000113-IDPS-00189
Group -
The Cisco ASA must be configured to send log records to the syslog server for specific facility and severity level.
Without the capability to generate audit records with a severity code it is difficult to track and handle detection events. While auditing and logging are closely related, they are not the same. L...Rule Medium Severity -
SRG-NET-000089-IDPS-00010
Group -
The Cisco ASA must be configured to queue log records locally In the event that the central audit server is down or not reachable.
It is critical that when the IDPS is at risk of failing to process audit logs as required, it take action to mitigate the failure. Audit processing failures include: software/hardware errors; fail...Rule Medium Severity -
SRG-NET-000192-IDPS-00140
Group -
The Cisco ASA must be configured to block outbound traffic containing denial-of-service (DoS) attacks by ensuring an intrusion prevention policy has been applied to outbound communications traffic.

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
