Cisco IOS Switch NDM Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The Cisco switch must be configured to authenticate Network Time Protocol (NTP) sources using authentication that is cryptographically based.
If NTP is not authenticated, an attacker can introduce a rogue NTP server. This rogue server can then be used to send incorrect time information to network devices, which will make log timestamps i...Rule Medium Severity -
The Cisco switch must be configured to use FIPS-validated Keyed-Hash Message Authentication Code (HMAC) to protect the integrity of remote maintenance sessions.
Unapproved mechanisms that are used for authentication to the cryptographic module are not verified and therefore cannot be relied on to provide confidentiality or integrity, and DOD data may be co...Rule High Severity -
The Cisco switch must be configured to generate audit records when successful/unsuccessful logon attempts occur.
Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an in...Rule Medium Severity -
The Cisco switch must be configured to support organizational requirements to conduct backups of the configuration when changes occur.
System-level information includes default and customized settings and security attributes, including access control lists (ACLs) that relate to the network device configuration, as well as software...Rule Medium Severity -
The Cisco switch must be configured to send log data to at least two central log servers for the purpose of forwarding alerts to the administrators and the information system security officer (ISSO).
The aggregation of log data kept on a syslog server can be used to detect attacks and trigger an alert to the appropriate security personnel. The stored log data can used to detect weaknesses in se...Rule High Severity -
The Cisco switch must be running an IOS release that is currently supported by Cisco Systems.
Network devices running an unsupported operating system lack current security fixes required to mitigate the risks associated with recent vulnerabilities. Running a supported release enables operat...Rule High 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.
