Vulnerability discussion

It is detrimental for operating systems to provide, or install by default, functionality exceeding requirements or mission objectives. These unnecessary capabilities or services are often overlooked and therefore may remain unsecured. They increase the risk to the platform by providing additional attack vectors.Operating systems 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 (e.g., key missions, functions). Examples of non-essential capabilities include but are not limited to games, software packages, tools, and demonstration software not related to requirements or providing a wide array of functionality not required for every mission but that cannot be disabled.The "rshd" service must be disabled.

Check content

To check if the "rshd" service is disabled, use the following command: /usr/bin/sudo /bin/launchctl print-disabled system | /usr/bin/grep com.apple.rshd If the results do not show the following, this is a finding: "com.apple.rshd" => true

Fix text

To disable the "rshd" service, run the following command: /usr/bin/sudo /bin/launchctl disable system/com.apple.rshd The system may need to be restarted for the update to take effect.

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.
