The 'gpgcheck' option controls whether
RPM packages' signatures are always checked prior to installation.
To configure yum to check package signatures before installing
them, ensure the following line appears in '/etc/yum.conf' in
the '[main]' section:
'gpgcheck=1'
Parameter:
[yes/no]
Technical Mechanism:
Verifying the authenticity of the software prior to installation
validates the integrity of the patch or upgrade received from
a vendor. This ensures the software has not been tampered with and
that it has been provided by a trusted vendor. Self-signed
certificates are disallowed by this requirement. Certificates
used to verify the software must be from an approved Certificate
Authority (CA).
