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.
Without cryptographic integrity protections, information can be altered by unauthorized users without detection. Cryptographic mechanisms used for protecting the integrity of information include, ...Rule Medium Severity -

The Palo Alto Networks security platform must deny network communications traffic by default and allow network communications traffic by exception (i.e., deny all, permit by exception).
A deny-all, permit-by-exception network communications traffic policy ensures that only those connections that are essential and approved are allowed. As a managed boundary interface between netwo...Rule Medium Severity -

The Palo Alto Networks security platform must update malicious code protection mechanisms and signature definitions whenever new releases are available in accordance with organizational configuration management policy and procedures.
In order to minimize any potential negative impact to the organization caused by malicious code, malicious code must be identified and eradicated. Malicious code includes viruses, worms, Trojan hor...Rule Medium Severity -
