Discussion

Installation of any nontrusted software, patches, service packs, device drivers, or operating system components can significantly affect the overall security of the operating system. Ensuring all packages' cryptographic signatures are valid prior to installation ensures the provenance of the software and protects against malicious tampering.

Check Content

At the command line, run the following command:

# grep -s nosignature /usr/lib/rpm/rpmrc /etc/rpmrc ~root/.rpmrc

If the command returns any output, this is a finding.

Fix Text

Open the file containing "nosignature" with a text editor and remove the option.
