Discussion

In order 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 HP FlexFabric Switch 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 to conduct official business or to address authorized quality of life issues.

Check Content

Check if unsecured protocols and services are disabled on the HP FlexFabric Switch:

[HP] display ftp-server

FTP is not configured.

[HP] display current-configuration | include telnet

Note: When Telnet server is enabled, the output for this command is telnet server enable.

If all unnecessary and non-secure functions, ports, protocols, and services are not disabled, this is a finding.
