Palo Alto Networks NDM Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The Palo Alto Networks security platform must produce audit log records containing information (FQDN, unique hostname, management IP address) to establish the source of events.
In order to compile an accurate risk assessment and provide forensic analysis, it is essential for security personnel to know the source of the event. The source may be a component, module, or pro...Rule Low Severity -
The Palo Alto Networks security platform must be configured to prohibit the use of all unnecessary and/or nonsecure functions, ports, protocols, and/or services, as defined in the PPSM CAL and vulnerability assessments.
In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable...Rule Medium Severity -
The Palo Alto Networks security platform must uniquely identify and authenticate organizational administrators (or processes acting on behalf of organizational administrators).
To assure accountability and prevent unauthenticated access, organizational administrators must be uniquely identified and authenticated for all network management accesses to prevent potential mis...Rule Medium Severity -
The Palo Alto Networks security platform must implement replay-resistant authentication mechanisms for network access to privileged accounts.
A replay attack may enable an unauthorized user to gain access to the application. Authentication sessions between the authenticator and the application validating the user credentials must not be ...Rule Medium Severity -
If multifactor authentication is not available and passwords must be used, the Palo Alto Networks security platform must enforce password complexity by requiring that at least one uppercase character be used.
Use of a complex passwords helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisti...Rule Medium Severity -
If multifactor authentication is not available and passwords must be used, the Palo Alto Networks security platform must enforce password complexity by requiring that at least one numeric character be used.
Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resistin...Rule Medium Severity -
If multifactor authentication is not available and passwords must be used, the Palo Alto Networks security platform must require that when a password is changed, the characters are changed in at least 8 of the positions within the password.
If the application allows the user to consecutively reuse extensive portions of passwords, this increases the chances of password compromise by increasing the window of opportunity for attempts at ...Rule Medium Severity -
The Palo Alto Networks security platform must terminate management sessions after 10 minutes of inactivity except to fulfill documented and validated mission requirements.
Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port th...Rule High Severity -
The Palo Alto Networks security platform must automatically lock the account until the locked account is released by an administrator when three unsuccessful logon attempts in 15 minutes are exceeded.
By limiting the number of failed logon attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced. Limits are imposed by locking the a...Rule Medium Severity -
The Palo Alto Networks security platform must have alarms enabled.
It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impe...Rule Low Severity -
The Palo Alto Networks security platform must compare internal information system clocks at least every 24 hours with an authoritative time server.
Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when condu...Rule Low Severity -
The Palo Alto Networks security platform must synchronize internal information system clocks to the authoritative time source when the time difference is greater than one second.
Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when condu...Rule Low Severity -
The Palo Alto Networks security platform must be configured to synchronize internal information system clocks with the primary and secondary time sources located in different geographic regions using redundant authoritative time sources.
The loss of connectivity to a particular authoritative time source will result in the loss of time synchronization (free-run mode) and increasingly inaccurate time stamps on audit events and other ...Rule Medium Severity -
The Palo Alto Networks security platform must record time stamps for audit records that can be mapped to Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT).
If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis. Time stamps generated by the application include date and time and ...Rule Medium Severity -
The Palo Alto Networks security platform must only allow the use of secure protocols that implement cryptographic mechanisms to protect the integrity of maintenance and diagnostic communications for nonlocal maintenance sessions.
This requires the use of secure protocols instead of their unsecured counterparts, such as SSH instead of telnet, SCP instead of FTP, and HTTPS instead of HTTP. Note that HTTP OCSP is permitted to ...Rule Medium Severity -
The Palo Alto Networks security platform must use automated mechanisms to alert security personnel to threats identified by authoritative sources (e.g., CTOs) and IAW CJCSM 6510.01B.
CJCSM 6510.01B, "Cyber Incident Handling Program", in subsection e.(6)(c) sets forth three requirements for Cyber events detected by an automated system: If the cyber event is detected by an automa...Rule Medium Severity -
The Palo Alto Networks security platform must use DoD-approved PKI rather than proprietary or self-signed device certificates.
DoD Instruction 8520.02, Public Key Infrastructure (PKI) and Public Key (PK) Enabling mandates that certificates must be issued by the DoD PKI or by a DoD-approved PKI for authentication, digital s...Rule Medium Severity -
The Palo Alto Networks security platform must not use the default admin account password.
To assure accountability and prevent unauthenticated access, organizational administrators must be uniquely identified and authenticated for all network management accesses to prevent potential mis...Rule High Severity -
The Palo Alto Networks security platform must authenticate Network Time Protocol sources.
If Network Time Protocol is not authenticated, an attacker can introduce a rogue NTP server. This rogue server can then be used to send incorrect time information to network devices, which will ma...Rule Medium Severity -
The Palo Alto device must be configured with only one local account to be used as the account of last resort in the event the authentication server is unavailable.
Authentication for administrative (privileged level) access to the device is required at all times. An account can be created on the device's local database for use when the authentication server i...Rule Medium Severity

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
