Description
To prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable unused or unnecessary physical and logical ports/protocols on information systems. Network devices are capable of providing a wide variety of functions and services. Some of the functions and services provided by default may not be necessary to support essential organizational operations. Additionally, it is sometimes convenient to provide multiple services from a single component (e.g., email and web services); however, doing so increases risk over limiting the services provided by any one component. To support the requirements and principles of least functionality, the network device must support the organizational requirements providing only essential capabilities and limiting the use of ports, protocols, and/or services to only those required, authorized, and approved. Some network devices have capabilities enabled by default; if these capabilities are not necessary, they must be disabled. If a particular capability is used, then it must be documented and approved.

ℹ️ Check
Determine if the network device prohibits the use of all unnecessary and/or nonsecure functions, ports, protocols, and/or services. Verify the configuration does not include unnecessary or nonsecure protocols and services: ip telnet server enable rest api restconf eula-consent support-assist accept If any unnecessary or nonsecure functions are permitted, this is a finding.

✔️ Fix
Configure the OS10 Switch to prohibit the use of all unnecessary and/or nonsecure functions, ports, protocols, and/or services: OS10(config)# no ip telnet server enable OS10(config)# no rest api restconf OS10(config)# eula-consent support-assist reject
