PANW-AG-000020 - The Palo Alto Networks security platform, if used as a TLS gateway/decryption point or VPN concentrator, must use NIST FIPS-validated cryptography to protect the integrity of remote access sessions.

Details

Without cryptographic integrity protections, information can be altered by unauthorized users without detection. Cryptographic mechanisms used for protecting the integrity of information include, for example, signed hash functions using asymmetric cryptography enabling distribution of the public key to verify the hash information while maintaining the confidentiality of the secret key used to generate the hash.



Remote access is access to DoD nonpublic information systems by an authorized user (or an information system) communicating through an external, non-organization-controlled network. Remote access methods include broadband and wireless connections. Remote access methods include, for example, proxied remote encrypted traffic (e.g., TLS gateways, web content filters, and webmail proxies).



NOTE: Please review the benchmark to ensure target compliance.


Solution

If the Palo Alto Networks security platform is used as a TLS gateway/decryption point or VPN concentrator, it must use NIST FIPS-validated cryptography.

Power off the device by unplugging it from the electrical outlet.

Connect a console cable from the console port to a computer serial port, and use a terminal program to connect to the Palo Alto Networks device.

The serial parameters are 9600 baud, 8 data bits, no parity, and 1 stop bit.

A USB to serial adapter will be necessary if the computer does not have a serial port.

During the boot sequence, this message will appear:
'Autoboot to default partition in 5 seconds'.

Enter 'maint' to boot to 'maint' partition.

Enter 'maint' to enter maintenance mode.

Press 'Enter', and the 'Maintenance Recovery tool' menu will appear.

Select 'Set FIPS Mode' (or select fips-cc for more recent versions) from the menu; once the device has finished rebooting, it will be in FIPS mode.

Note: This will remove all installed licenses and disable the serial port.
