Vulnerability discussion

Privileged access contains control and configuration information and is particularly sensitive, so additional protections are necessary. This is maintained by using cryptographic mechanisms such as encryption to protect confidentiality.Nonlocal maintenance and diagnostic activities are those activities conducted by individuals communicating through a network, either an external network (e.g., the Internet) or an internal network. Local maintenance and diagnostic activities are those activities carried out by individuals physically present at the information system or information system component and not communicating across a network connection. This requirement applies to hardware/software diagnostic test equipment or tools. This requirement does not cover hardware/software components that may support information system maintenance, yet are a part of the system (e.g., the software implementing "ping," "ls," "ipconfig," or the hardware and software implementing the monitoring port of an Ethernet switch).The operating system can meet this requirement through leveraging a cryptographic module.

Check content

Verify the operating system implements cryptographic mechanisms to protect the confidentiality of nonlocal maintenance and diagnostic communications, when used for nonlocal maintenance sessions. If it does not, this is a finding.

Fix text

Configure the operating system to implement cryptographic mechanisms to protect the confidentiality of nonlocal maintenance and diagnostic communications, when used for nonlocal maintenance sessions.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
