cyberstrikeus 2.2.2 Ensure rsh client is not installed (Automated)
Profile
- Level 1 - Server
- Level 1 - Workstation
Description
The rsh-client package contains the client commands for the rsh services.
Rationale
These legacy clients contain numerous security exposures and have been replaced with the more secure SSH package. Even if the server is removed, it is best to ensure the clients are also removed to prevent users from inadvertently attempting to use these commands and therefore exposing their credentials. Note that removing the rsh package removes the clients for rsh, rcp and rlogin.
Audit Procedure
Command Line
Run the following command to verify rsh-client is not installed:
# dpkg-query -W -f='${binary:Package}\t${Status}\t${db:Status-Status}\n' rsh-client
Verify rsh-client is not installed.
Expected Result
rsh-client package should not be installed.
Remediation
Command Line
Run the following command to remove rsh-client:
# apt purge rsh-client
Default Value
rsh-client is not installed by default.
