The Palo Alto Networks security platform must display the Standard Mandatory DoD Notice and Consent Banner before granting access to the device.
Low Severity
<VulnDiscussion>Display of the DoD-approved use notification before granting access to the network device ensures privacy and security notification verbiage used is consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. System use notifications are required only for access via logon interfaces with human users.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
The Palo Alto Networks security platform must generate audit records when successful/unsuccessful attempts to access privileges occur.
Medium Severity
<VulnDiscussion>Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. By default, the Configuration Log contains the administrator username, client (Web or CLI), and date and time for any changes to configurations and for configuration commit actions. The System Log also shows both successful and unsuccessful attempts for configuration commit actions. The System Log and Configuration Log can be configured to send log messages by severity level to specific destinations; the Panorama management console, an SNMP console, an e-mail server, or a syslog server. Since both the System Log and Configuration Log contain information concerning the use of privileges, both must be configured to send messages to a syslog server at a minimum.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
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.
Low Severity
<VulnDiscussion>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 process within the device or an external session, administrator, or device. Associating information about where the source of the event occurred provides a means of investigating an attack; recognizing resource utilization or capacity thresholds; or identifying an improperly configured device. The device must have a unique hostname that can be used to identify the device; fully qualified domain name (FQDN), hostname, or management IP address is used in audit logs to identify the source of a log message.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
SRG-APP-000142-NDM-000245
1 Rule
<GroupDescription></GroupDescription>
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.
Medium Severity
<VulnDiscussion>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 unused or unnecessary physical and logical ports/protocols on information systems. Network devices are capable of providing a wide variety of functions and services. Some of the functions and services provided by default may not be necessary to support essential organizational operations. Additionally, it is sometimes convenient to provide multiple services from a single component (e.g., email and web services); however, doing so increases risk over limiting the services provided by any one component. To support the requirements and principles of least functionality, the network device must support the organizational requirements providing only essential capabilities and limiting the use of ports, protocols, and/or services to only those required, authorized, and approved to conduct official business or to address authorized quality of life issues. The Palo Alto Networks security platform uses a hardened operating system in which unnecessary services are not present. The device has a DNS, NTP, update, and e-mail client installed. Note that these are client applications and not servers; additionally, each has a valid purpose. However, local policy may dictate that the update service, e-mail client, and statistics (reporting) service capabilities not be used. DNS can be either "Server" or "Proxy"; both are allowed unless local policy declares otherwise. NTP and SNMP are necessary functions.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Palo Alto Networks security platform must uniquely identify and authenticate organizational administrators (or processes acting on behalf of organizational administrators).
Medium Severity
<VulnDiscussion>To assure accountability and prevent unauthenticated access, organizational administrators must be uniquely identified and authenticated for all network management accesses to prevent potential misuse and compromise of the system.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
SRG-APP-000156-NDM-000250
1 Rule
<GroupDescription></GroupDescription>
The Palo Alto Networks security platform must implement replay-resistant authentication mechanisms for network access to privileged accounts.
Medium Severity
<VulnDiscussion>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 vulnerable to a replay attack. An authentication process resists replay attacks if it is impractical to achieve a successful authentication by recording and replaying a previous authentication message. Techniques used to address this include protocols using nonces (e.g., numbers generated for a specific one-time use) or challenges (e.g., TLS, WS_Security). Additional techniques include time-synchronous or challenge-response one-time authenticators. Of the three authentication protocols on the Palo Alto Networks security platform, only Kerberos is inherently replay-resistant. If LDAP is selected, TLS must also be used. If RADIUS is used, the device must be operating in FIPS mode.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
If multifactor authentication is not available and passwords must be used, the Palo Alto Networks security platform must enforce a minimum 15-character password length.
Medium Severity
<VulnDiscussion>Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password length is one factor of several that helps to determine strength and how long it takes to crack a password. The shorter the password, the lower the number of possible combinations that needs to be tested before the password is compromised. Use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
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.
Medium Severity
<VulnDiscussion>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 guessing and brute-force attacks. The number of changed characters refers to the number of changes required with respect to the total number of positions in the current password. In other words, characters may be the same within the two passwords; however, the positions of the like characters must be different.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
The Palo Alto Networks security platform must prohibit the use of unencrypted protocols for network access to privileged accounts.
Medium Severity
<VulnDiscussion>Passwords need to be protected at all times, and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily compromised. Network devices can accomplish this by making direct function calls to encryption modules or by leveraging operating system encryption capabilities.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
SRG-APP-000190-NDM-000267
1 Rule
<GroupDescription></GroupDescription>
The Palo Alto Networks security platform must terminate management sessions after 10 minutes of inactivity except to fulfill documented and validated mission requirements.
High Severity
<VulnDiscussion>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 that has been left unattended. In addition, quickly terminating an idle session will also free up resources committed by the managed network element. Terminating network connections associated with communications sessions includes, for example, de-allocating associated TCP/IP address/port pairs at the operating system level, or de-allocating networking assignments at the application level if multiple application sessions are using a single, operating system-level network connection. This does not mean that the device terminates all sessions or network access; it only ends the inactive session and releases the resources associated with that session. Device management sessions are normally ended by the Administrator when he or she has completed the management activity. The session termination takes place from the web client by selecting "Logout" (located at the bottom-left of the GUI window) or using the command line commands "exit" or "quit" at Operational mode.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
Administrators in the role of Security Administrator, Cryptographic Administrator, or Audit Administrator must not also have the role of Audit Administrator.
Medium Severity
<VulnDiscussion>The Palo Alto Networks security platform has both pre-configured and configurable Administrator roles. Administrator roles determine the functions that the administrator is permitted to perform after logging in. Roles can be assigned directly to an administrator account, or define role profiles, which specify detailed privileges, and assign those to administrator accounts. There are three preconfigured roles designed to comply with Common Criteria requirements - Security Administrator, Audit Administrator, and Cryptographic Administrator. Of the three, only the Audit Administrator can delete audit records. The Palo Alto Networks security platform can use both pre-configured and configurable Administrator roles.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
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.
Medium Severity
<VulnDiscussion>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 account. This should not be configured in Device >> Setup >> Management >> Authentication Settings; instead, an authentication profile should be configured with lockout settings of three failed attempts and a lockout time of zero minutes. The Lockout Time is the number of minutes that a user is locked out if the number of failed attempts is reached (0-60 minutes, default 0). 0 means that the lockout is in effect until it is manually unlocked.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Palo Alto Networks security platform must generate an immediate alert when allocated audit record storage volume reaches 75% of repository maximum audit record storage capacity.
Low Severity
<VulnDiscussion>If security personnel are not notified immediately upon storage volume utilization reaching 75%, they are unable to plan for storage capacity expansion. This could lead to the loss of audit information. Note that while the network device must generate the alert, notification may be done by a management server.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
The Palo Alto Networks security platform must have alarms enabled.
Low Severity
<VulnDiscussion>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 impending failure of the audit capability, and system operation may be adversely affected. Alerts provide organizations with urgent messages. Real-time alerts provide these messages immediately (i.e., the time from event detection to alert occurs in seconds or less).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
The Palo Alto Networks security platform must compare internal information system clocks at least every 24 hours with an authoritative time server.
Low Severity
<VulnDiscussion>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 conducting forensic analysis and investigating system events. Synchronizing internal information system clocks provides uniformity of time stamps for information systems with multiple system clocks and systems connected over a network. Network Time Protocol (NTP) is used to synchronize the system clock of a computer to reference time source. The Palo Alto Networks security platform can be configured to use specified Network Time Protocol (NTP) servers. For synchronization with the NTP server(s), NTP uses a minimum polling value of 64 seconds and a maximum polling value of 1024 seconds. These minimum and maximum polling values are not configurable on the firewall.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<VulnDiscussion>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 conducting forensic analysis and investigating system events. Synchronizing internal information system clocks provides uniformity of time stamps for information systems with multiple system clocks and systems connected over a network. The Palo Alto Networks security platform can be configured to use specified Network Time Protocol (NTP) servers. Network Time Protocol (NTP) is used to synchronize the system clock of a computer to reference time source. Sources outside of the configured acceptable allowance (drift) may be inaccurate. When properly configured, NTP will synchronize all participating computers to within a few milliseconds of the reference time source.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
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.
Medium Severity
<VulnDiscussion>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 functions. Multiple time sources provide redundancy by including a secondary source. Time synchronization is usually a hierarchy; clients synchronize time to a local source while that source synchronizes its time to a more accurate source. DoD-approved solutions consist of a combination of a primary and secondary time source using a combination or multiple instances of the following: a time server designated for the appropriate DoD network (NIPRNet/SIPRNet); United States Naval Observatory (USNO) time servers; and/or the Global Positioning System (GPS). The secondary time source must be located in a different geographic region from the primary time source.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

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).
Medium Severity
<VulnDiscussion>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 must be expressed in Coordinated Universal Time (UTC), also known as Zulu time, a modern continuation of Greenwich Mean Time (GMT).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Palo Alto Networks security platform must accept and verify Personal Identity Verification (PIV) credentials.
Medium Severity
<VulnDiscussion>The use of PIV credentials facilitates standardization and reduces the risk of unauthorized access. DoD has mandated the use of the CAC to support identity management and personal authentication for systems covered under HSPD 12 and as a primary component of layered protection for national security systems.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Palo Alto Networks security platform must allow the use of a temporary password for system logons with an immediate change to a permanent password.
Medium Severity
<VulnDiscussion>Without providing this capability, an account may be created without a password. Non-repudiation cannot be guaranteed once an account is created if a user is not forced to change the temporary password upon initial logon. Temporary passwords are typically used to allow access to applications when new accounts are created or passwords are changed. It is common practice for administrators to create temporary passwords for user accounts that allow the users to log on yet force them to change the password once they have successfully authenticated.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
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.
Medium Severity
<VulnDiscussion>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 support OCSP where used. If unsecured protocols (lacking cryptographic mechanisms) are used for sessions, the contents of those sessions will be susceptible to manipulation, potentially allowing alteration and hijacking of maintenance sessions.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Palo Alto Networks security platform must not use SNMP Versions 1 or 2.
High Severity
<VulnDiscussion>SNMP Versions 1 and 2 are not considered secure. Without the strong authentication and privacy that is provided by the SNMP Version 3 User-based Security Model (USM), an unauthorized user can gain access to network management information used to launch an attack against the network. SNMP Versions 1 and 2 cannot authenticate the source of a message nor can they provide encryption. Without authentication, it is possible for nonauthorized users to exercise SNMP network management functions. It is also possible for nonauthorized users to eavesdrop on management information as it passes from managed systems to the management system.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Palo Alto Networks security platform must off-load audit records onto a different system or media than the system being audited.
Medium Severity
<VulnDiscussion>Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity. The Palo Alto Networks security platform has multiple log types; at a minimum, the Traffic, Threat, System, and Configuration logs must be sent to a Syslog server.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
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.
Medium Severity
<VulnDiscussion>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 automated system, an alert will be sent to the POC designated for receiving such automated alerts. CC/S/A/FAs that maintain automated detection systems and sensors must ensure that a POC for receiving the alerts has been defined and that the IS configured to send alerts to that POC. The POC must then ensure that the cyber event is reviewed as part of the preliminary analysis phase and reported to the appropriate individuals if it meets the criteria for a reportable cyber event or incident. By immediately displaying an alarm message, potential security violations can be identified more quickly even when administrators are not logged on to the network device. An example of a mechanism to facilitate this would be through the utilization of SNMP traps. The Palo Alto Networks security platform can be configured to send messages to an SNMP server and to an e-mail server as well as a Syslog server. SNMP traps can be generated for each of the five logging event types on the firewall: traffic, threat, system, hip, config. For this requirement, only the threat logs must be sent. Note that only traffic that matches an action in a rule will be logged and forwarded. In the case of traps, the messages are initiated by the firewall and sent unsolicited to the management stations. The use of e-mail as a notification method may result in a very larger number of messages being sent and possibly overwhelming the e-mail server as well as the POC. The use of SNMP is preferred over e-mail in general, but organizations may want to use e-mail in addition to SNMP for high-priority messages.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
The Palo Alto Networks security platform must employ centrally managed authentication server(s).
Medium Severity
<VulnDiscussion>The use of authentication servers or other centralized management servers for providing centralized authentication services is required for network device management. Maintaining local administrator accounts for daily usage on each network device without centralized management is not scalable or feasible. Without centralized management, it is likely that credentials for some network devices will be forgotten, leading to delays in administration, which itself leads to delays in remediating production problems and in addressing compromises in a timely fashion. Only the emergency administration account, also known as the account of last resort, can be locally configured on the device.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Palo Alto Networks security platform must not use the default admin account password.
High Severity
<VulnDiscussion>To assure accountability and prevent unauthenticated access, organizational administrators must be uniquely identified and authenticated for all network management accesses to prevent potential misuse and compromise of the system. The use of a default password for any account, especially one for administrative access, can quickly lead to a compromise of the device and subsequently, the entire enclave or system. The "admin" account is intended solely for the initial setup of the device and must be disabled when the device is initially configured. The default password for this account must immediately be changed at the first login of an authorized administrator.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Palo Alto Networks security platform must generate an audit log record when the Data Plane CPU utilization is 100%.
Medium Severity
<VulnDiscussion>Auditing and logging are key components of any security architecture. Logging the actions of specific events provides a means to investigate an attack; to recognize resource utilization or capacity thresholds; or to identify an improperly configured network device. If auditing is not comprehensive, it will not be useful for intrusion monitoring, security investigations, and forensic analysis. If the Data Plane CPU utilization is 100%, this may indicate an attack or simply an over-utilized device. In either case, action must be taken to identify the source of the issue and take corrective action.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Palo Alto Networks security platform must authenticate Network Time Protocol sources.
Medium Severity
<VulnDiscussion>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 make log timestamps inaccurate and affected scheduled actions. NTP authentication is used to prevent this tampering by authenticating the time source.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
