    SV-77037r1_rule PANW-AG-000015 CCI-000067 MEDIUM The Palo Alto Networks security platform, if used to provide intermediary services for remote access communications traffic (TLS or SSL decryption), must ensure inbound and outbound traffic is monitored for compliance with remote access security policies. Automated monitoring of remote access traffic allows organizations to detect cyber attacks and also ensure ongoing compliance with remote access policies by inspecting connection activities of remote access capabilities. Remote access methods include bot

Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. Encryption provides a means to secure the remote connection so as to prevent unauthorized access to the data tra
    SV-77041r3_rule PANW-AG-000017 CCI-000068 MEDIUM The Palo Alto Networks security platform that stores secret or private keys must use FIPS-approved key management technology and processes in the production and control of private/secret cryptographic keys. Private key data is used to prove that the entity presenting a public key certificate is the certificate's rightful owner. Compromise of private key data allows an adversary to impersonate the key holder. Private key data associated with software certif

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 crypto
    SV-77045r1_rule PANW-AG-000024 CCI-000133 LOW The Palo Alto Networks security platform must log violations of security policies. Without establishing the source of the event, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. In order to compile an accurate risk assessment and provide forensic analysis, security personnel need to
    SV-77047r1_rule PANW-AG-000035 CCI-000381 MEDIUM The Palo Alto Networks security platform must only enable User-ID on trusted zones. User-ID can use Windows Management Instrumentation (WMI) probing as a method of mapping users to IP addresses. If this is used, the User-ID Agent will send a probe to each learned IP address in its list to verify that the same user is still logged in. The

A certificate's certification path is the path from the end entity certificate to a trusted root certification authority (CA). Certification path validation is necessary for a relying party to make an informed decision regarding acceptance of an end entit
    SV-77057r2_rule PANW-AG-000047 CCI-001094 MEDIUM The Palo Alto Networks security platform must protect against the use of internal systems from launching Denial of Service (DoS) attacks against other networks or endpoints. DoS attacks can take multiple forms but have the common objective of overloading or blocking a network or host to deny or seriously degrade performance. If the network does not provide safeguards against DoS attack, network resources will be unavailable t
    SV-77059r1_rule PANW-AG-000049 CCI-001094 MEDIUM The Palo Alto Networks security platform must block phone home traffic. A variety of Distributed Denial of Service (DDoS) attacks and other attacks use "botnets" as an attack vector.
