Description
A compromised switch introduces risk to the entire network infrastructure as well as data resources that are accessible via the network. The perimeter defense has no oversight or control of attacks by malicious users within the network. Preventing network breaches from within is dependent on implementing a comprehensive defense-in-depth strategy, including securing each device connected to the network. This is accomplished by following and implementing all security guidance applicable for each node type. A fundamental step in securing each switch is to enable only the capabilities required for operation.

Who does this work

5 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-253948r843877_chk)

Review the switch configuration and verify the switch does not have an unnecessary or non-secure services enabled. For example, the following directives should not be in the configuration (deleted) or, if present, must be disabled (inactive): Verify the following commands are not present: [edit system services] finger; ftp; rlogin; telnet; xnm-clear-text; tftp; rest { http; } web-management { http; https; } Note: If the services listed above are marked "inactive", they are not enabled. For example, although the FTP stanza is present in the following snippet, it is disabled (inactive): [edit system services] inactive: ftp; Because J-Web was not included in the FIPS certification, verify the web-management process is disabled. [edit system services] web-management disable; If any unnecessary services are enabled, this is a finding.

Fix Text (F-57351r843876_fix)

Disable the following services: If present, delete the following directives: delete system services finger delete system services ftp delete system services rlogin delete system services telnet delete system services xnm-clear-text delete system services tftp delete system services rest http delete system services web-management Disable the web-management process: set system processes web-management disable
