Cisco IOS Switch RTR Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The Cisco switch must be configured to enable routing protocol authentication using FIPS 198-1 algorithms with keys not exceeding 180 days of lifetime.
A rogue router could send a fictitious routing update to convince a site's perimeter router to send traffic to an incorrect or even a rogue destination. This diverted traffic could be analyzed to l...Rule Medium Severity -
The Cisco switch must be configured to have all inactive Layer 3 interfaces disabled.
An inactive interface is rarely monitored or controlled and may expose a network to an undetected attack on that interface. Unauthorized personnel with access to the communication facility could ga...Rule Low Severity -
The Cisco switch must be configured to have gratuitous ARP disabled on all external interfaces.
A gratuitous ARP is an ARP broadcast in which the source and destination MAC addresses are the same. It is used to inform the network about a host IP address. A spoofed gratuitous ARP message can c...Rule Medium Severity -
The Cisco switch must be configured to have IP directed broadcast disabled on all interfaces.
An IP directed broadcast is a datagram sent to the broadcast address of a subnet that is not directly attached to the sending machine. The directed broadcast is routed through the network as a unic...Rule Low Severity -
The Cisco switch must be configured to have Internet Control Message Protocol (ICMP) unreachable messages disabled on all external interfaces.
The ICMP supports IP traffic by relaying information about paths, routes, and network conditions. Switches automatically send ICMP messages under a wide variety of conditions. Host unreachable ICMP...Rule Medium Severity -
The Cisco switch must be configured to have Internet Control Message Protocol (ICMP) mask reply messages disabled on all external interfaces.
The ICMP supports IP traffic by relaying information about paths, routes, and network conditions. Switches automatically send ICMP messages under a wide variety of conditions. Mask Reply ICMP messa...Rule Medium Severity -
The Cisco switch must be configured to have Internet Control Message Protocol (ICMP) redirect messages disabled on all external interfaces.
The ICMP supports IP traffic by relaying information about paths, routes, and network conditions. Switches automatically send ICMP messages under a wide variety of conditions. Redirect ICMP message...Rule Medium Severity -
The Cisco switch must be configured to log all packets that have been dropped at interfaces via an access control list (ACL).
Auditing and logging are key components of any security architecture. It is essential for security personnel to know what is being done or attempted to be done, and by whom, to compile an accurate ...Rule Low Severity -
The Cisco switch must be configured to produce audit records containing information to establish where the events occurred.
Without establishing where events occurred, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. To compile an accurate risk assessment and prov...Rule Medium Severity -
The Cisco switch must be configured to produce audit records containing information to establish the source of the events.
Without establishing the source of the event, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. To compile an accurate risk assessment and pr...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.
