Cisco ASA IPS Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • SRG-NET-000074-IDPS-00059

    Group
  • The Cisco ASA must be configured to produce audit records containing sufficient information to establish what type of event occurred.

    Without establishing what type of event occurred, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack. Associating an event type with each ev...
    Rule Medium Severity
  • 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
  • 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
  • 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 IDPS must include protection against DoS attacks that originate from inside the enclave which can affect either internal or external systems. These attacks may use legitimate or rogue endpoints...
    Rule Medium Severity
  • The Cisco ASA must block any prohibited mobile code at the enclave boundary when it is detected.

    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
  • The Cisco ASA must be configured to install updates for signature definitions and vendor-provided rules.

    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
  • The Cisco ASA must be configured to automatically install updates to signature definitions 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...

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.
