Discussion

Changes to any software components can have significant effects on the overall security of the network device. Verifying software components have been digitally signed using a certificate that is recognized and approved by the organization ensures the software has not been tampered with and has been provided by a trusted vendor. Accordingly, patches, service packs, or application components must be signed with a certificate recognized and approved by the organization. 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 has been provided by a trusted vendor. Self-signed certificates are disallowed by this requirement. The device should not have to verify the software again. This requirement does not mandate DOD certificates for this purpose; however, the certificate used to verify the software must be from an approved certificate authority (CA).

Check Content

Determine if the OS10 Switch prevents the installation of patches, service packs, or application components without verifying the software component has been digitally signed using a certificate that is recognized and approved by the organization. 

Image install commands verify signatures if OS10 secure-boot is enabled. Verify that OS10 secure-boot feature is enabled with the following command:

OS10# show secure-boot status
Last boot was via secure boot : yes
Secure boot configured : yes
Latest startup config protected: yes
BIOS secure boot:
BIOS Secure boot configured: yes

If BIOS Secure boot is not configured, this is a finding.

Fix Text

Install OS10 images with digital signature verification using the following command.

Enable OS10 secure-boot, if necessary, with the following command. Reload the switch after enabling secure boot.

OS10# secure-boot enable

With OS10 secure-boot enabled, install OS10 images with the following command:

OS10# image secure-install <image-filepath> {sha256 signature <signature-filepath> | gpg signature <signature-filepath> | pki signature <signature-filepath> publickey
<key-file>}
