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