The SMS must be configured to remove or disable nonessential capabilities on SMS and TPS, which are not required for operation or not related to IDPS functionality. |
An IDPS can be capable of providing a wide variety of capabilities. Not all of these capabilities are necessary. Unnecessary services, functions, and applications increase the attack surface (sum of attack vectors) of a system. These unnecessary capabilities are often overlooked and therefore, may remain unsecured.
Examples of unneeded services... |

In the event of a logging failure caused by the lack of audit record storage capacity, the SMS must continue generating and storing audit records, overwriting the oldest audit records in a first-in-first-out manner using Audit Log maintenance. |
It is critical that when the TPS is at risk of failing to process audit logs as required, it takes action to mitigate the failure.
The IDPS performs a critical security function, so its continued operation is imperative. Since availability of the TPS is an overriding concern, shutting down the... |
|
V-242177
|
Medium |
The TPS must provide audit record generation capability for events where communication traffic is blocked or restricted based on policy filters, rules, signatures, and anomaly analysis. |
To support the centralized analysis capability, the IDPS components must be able to provide the information in a format (e.g., Syslog) that can be extracted and used, allowing the application to effectively review and analyze the log records. |
|
V-242176
|
Medium |
The TPS must provide audit record generation capability for detection events based on implementation of policy filters, 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 auditing and logging are closely related, they are not the same. Logging is recording data about events that take place in... |
