The HP FlexFabric switch must be configured to send log data to a syslog server for the purpose of forwarding alerts to the administrators and the ISSO.

The HP FlexFabric switch must be configured to send SNMP traps and notifications to the SNMP manager for the purpose of sending alarms and notifying appropriate personnel as required by specific events.
If appropriate actions are not taken when a network device failure occurs, a denial of service condition may occur which could result in mission failure since the network would be operating without...Rule Medium Severity -
The HP FlexFabric Switch must limit the number of concurrent sessions to an organization-defined number for each administrator account and/or administrator account type.
Device management includes the ability to control the number of administrators and management sessions that manage a device. Limiting the number of allowed administrators and sessions per administr...Rule Low Severity -
The HP FlexFabric Switch must automatically audit account modification.
Since the accounts in the HP FlexFabric Switch are privileged or system-level accounts, account management is vital to the security of the HP FlexFabric Switch. Account management by a designated a...Rule Medium Severity -
The HP FlexFabric Switch must enforce approved authorizations for controlling the flow of management information within the HP FlexFabric Switch based on information flow control policies.
A mechanism to detect and prevent unauthorized communication flow must be configured or provided as part of the system design. If management information flow is not enforced based on approved autho...Rule Medium Severity -
The HP FlexFabric Switch must enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period.
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.Rule Medium Severity -
The HP FlexFabric Switch must display the Standard Mandatory DoD Notice and Consent Banner before granting access to the device.
Display of the DoD-approved use notification before granting access to the HP FlexFabric Switch ensures privacy and security notification verbiage used is consistent with applicable federal laws, E...Rule Medium Severity -
The HP FlexFabric Switch must provide audit record generation capability for DoD-defined auditable events within the HP FlexFabric Switch.
Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit re...Rule Low Severity -
The HP FlexFabric Switch must produce audit records containing information to establish where the events occurred.
In order to compile an accurate risk assessment and provide forensic analysis, it is essential for security personnel to know where events occurred, such as device hardware components, device softw...Rule Low Severity -

The HP FlexFabric Switch must enforce a minimum 15-character password length.
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 d...Rule Medium Severity -
If multifactor authentication is not supported and passwords must be used, the HP FlexFabric Switch must enforce password complexity by requiring that at least one lower-case 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 -
The HP FlexFabric Switch, when utilizing PKI-based authentication, must validate certificates by constructing a certification path (which includes status information) to an accepted trust anchor.
Without path validation, an informed trust decision by the relying party cannot be made when presented with any certificate not already explicitly trusted. A trust anchor is an authoritative entit...Rule Medium Severity -
The HP FlexFabric Switch must terminate all network connections associated with a device management session at the end of the session, or the session must be terminated after 10 minutes of inactivity except to fulfill documented and validated mission requirements.

The HP FlexFabric Switch must allocate audit record storage capacity in accordance with organization-defined audit record storage requirements.
In order to ensure network devices have a sufficient storage capacity in which to write the audit logs, they need to be able to allocate audit record storage capacity. The task of allocating audit ...Rule Medium Severity -
The HP FlexFabric Switch must synchronize internal information system clocks to the authoritative time source when the time difference is greater than the organization-defined time period.
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 Medium Severity -
The HP FlexFabric Switch 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 -
Applications used for nonlocal maintenance sessions must implement cryptographic mechanisms to protect the integrity of nonlocal maintenance and diagnostic communications.
