SRG-NET-000018-IDPS-00018
Group -
The Palo Alto Networks security platform must enable Antivirus, Anti-spyware, and Vulnerability Protection for all authorized traffic.
The flow of all communications traffic must be monitored and controlled so it does not introduce any unacceptable risk to the network infrastructure or data. Restricting the flow of communications...Rule Medium Severity -
SRG-NET-000077-IDPS-00062
Group -
The Palo Alto Networks security platform must produce audit records containing information to establish the source of the event, including, at a minimum, originating source address.
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 Palo Alto Networks security platform must capture traffic of detected/dropped malicious code.
Associating event outcome with detected events in the log provides a means of investigating an attack or suspected attack. The logs should identify what servers, destination addresses, application...Rule Medium Severity -
SRG-NET-000089-IDPS-00069
Group -
In the event of a logging failure caused by the lack of audit record storage capacity, the Palo Alto Networks security platform must continue generating and storing audit records if possible, overwriting the oldest audit records in a first-in-first-out manner.
It is critical that when the Palo Alto Networks security platform is at risk of failing to process audit logs as required, it takes action to mitigate the failure. The Palo Alto Networks security ...Rule Medium Severity -
SRG-NET-000192-IDPS-00140
Group -
The Palo Alto Networks security platform must have a denial-of-service (DoS) Protection Profile for outbound traffic applied to a policy for traffic originating from the internal zone going to the external zone.
The Palo Alto Networks security platform must include protection against DoS attacks that originate from inside the enclave which can affect either internal or external systems. These attacks may u...Rule Medium Severity -
SRG-NET-000229-IDPS-00163
Group -
The Palo Alto Networks security platform must detect and deny any prohibited mobile or otherwise malicious code at the enclave boundary.
Mobile code is defined as software modules obtained from remote systems, transferred across a network, and then downloaded and executed on a local system without explicit installation or execution ...Rule Medium Severity -
SRG-NET-000246-IDPS-00205
Group -
The Palo Alto Networks security platform must install updates for application software files, signature definitions, detection heuristics, and vendor-provided rules when new releases are available in accordance with organizational configuration management policy and procedures.
Failing to update malicious code protection mechanisms, including application software files, signature definitions, and vendor-provided rules, leaves the system vulnerable to exploitation by recen...Rule Medium Severity -
SRG-NET-000249-IDPS-00176
Group -
The Palo Alto Networks security platform must detect and drop any prohibited mobile or otherwise malicious code at internal boundaries.
Mobile code is defined as software modules obtained from remote systems, transferred across a network, and then downloaded and executed on a local system without explicit installation or execution ...Rule Medium Severity -
SRG-NET-000249-IDPS-00222
Group -
The Palo Alto Networks security platform must send an immediate (within seconds) alert to, at a minimum, the SA when malicious code is detected.
Without an alert, security personnel may be unaware of an impending failure of the audit capability, and the ability to perform forensic analysis and detect rate-based and other anomalies will be i...Rule Medium Severity -
SRG-NET-000251-IDPS-00178
Group -
The Palo Alto Networks security platform must automatically install updates to signature definitions, detection heuristics, and vendor-provided rules.
Failing to automatically update malicious code protection mechanisms, including application software files, signature definitions, and vendor-provided rules, leaves the system vulnerable to exploit...Rule Medium Severity

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.
