Enable module signature verification
An XCCDF Rule
Description
Check modules for valid signatures upon load.
Note that this option adds the OpenSSL development packages as a kernel build dependency so
that the signing tool can use its crypto library.
The configuration that was used to build kernel is available at /boot/config-*.
To check the configuration value for CONFIG_MODULE_SIG, run the following command:
grep CONFIG_MODULE_SIG /boot/config-*
For each kernel installed, a line with value "y" should be returned.
warning alert: Warning
There is no remediation for this besides re-compiling the kernel with the appropriate value for the config.
Rationale
Loaded modules must be signed.
