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.
Discussion
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 administrator is helpful in limiting risks related to DoS attacks. This requirement addresses concurrent sessions for administrative accounts and does not address concurrent sessions by a single administrator via multiple administrative accounts. The maximum number of concurrent sessions should be defined based upon mission needs and the operational environment for each system.
Fix Text
Configure the HP FlexFabric Switch to limit the number of concurrent sessions to an organization-defined number for all administrator accounts and administrator account types as shown in the following example: [HP] local-user admin [HP-luser-manage-admin] access-limit 3
Check Content
Review the HP FlexFabric Switch configuration to see if it limits the number of concurrent sessions to an organization-defined number for all administrator accounts and/or administrator account types: [HP] display local-user Device management user test: State: Active Service type: None Access limit: Enabled Max access number: 3 Current access number: 0 User group: system Bind attributes: Authorization attributes: Work directory: cfa0: User role list: network-admin If "Max access number:" line is not present, this is a finding.
The HP FlexFabric Switch must automatically disable accounts after a 35-day period of account inactivity.
Discussion
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. Inactive accounts could be reactivated or compromised by unauthorized users, allowing exploitation of vulnerabilities and undetected access to the HP FlexFabric Switch. This control does not include emergency administration accounts, which are meant for access to the HP FlexFabric Switch components in case of network failure.

The HP FlexFabric Switch must automatically audit account creation.
Discussion
Upon gaining access to a network device, an attacker will often first attempt to create a persistent method of reestablishing access. One way to accomplish this is to create a new account. Notification of account creation helps to mitigate this risk. Auditing account creation provides the necessary reconciliation that account management procedures are being followed. Without this audit trail, personnel without the proper authorization may gain access to critical network nodes.

The HP FlexFabric Switch must automatically audit account modification.
Discussion
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 authority ensures access to the HP FlexFabric Switch is being controlled in a secure manner by granting access to only authorized personnel with the appropriate and necessary privileges. Auditing account modification along with an automatic notification to appropriate individuals will provide the necessary reconciliation that account management procedures are being followed. If modifications to management accounts are not audited, reconciliation of account management procedures cannot be tracked.

The HP FlexFabric Switch must enforce the assigned privilege level for each administrator and authorizations for access to all commands relative to the privilege level in accordance with applicable policy for the device.
Discussion
To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoD-approved PKIs, all DoD systems must be properly configured to incorporate access control methods that do not rely solely on the possession of a certificate for access. Successful authentication must not automatically give an entity access to an asset or security boundary. Authorization procedures and controls must be implemented to ensure each authenticated entity also has a validated and current authorization. Authorization is the process of determining whether an entity, once authenticated, is permitted to access a specific asset. Network devices use access control policies and enforcement mechanisms to implement this requirement. Access control policies include identity-based policies, role-based policies, and attribute-based policies. Access enforcement mechanisms include access control lists, access control matrices, and cryptography. These policies and mechanisms must be employed by the HP FlexFabric Switch to control access between administrators (or processes acting on behalf of administrators) and objects (e.g., device commands, files, records, processes) in the HP FlexFabric Switch.

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.
Discussion
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 authorizations, the HP FlexFabric Switch may become compromised. Information flow control regulates where management information is allowed to travel within a network device. The flow of all management information must be monitored and controlled so it does not introduce any unacceptable risk to the HP FlexFabric Switch or data. Application-specific examples of enforcement occur in systems that employ rule sets or establish configuration settings that restrict information system services or message-filtering capability based on message content (e.g., implementing key word searches or using document characteristics). Applications providing information flow control must be able to enforce approved authorizations for controlling the flow of management information within the system in accordance with applicable policy.
Fix Text
Configure the HP FlexFabric Switch for controlling the flow of management information within the HP FlexFabric Switch based on information flow control policies. Below is an example for an ACL configuration: [HP] acl number 3000 [HP-acl-adv-3000] description ACL to block traffic with invalid address [HP-acl-adv-3000] rule 0 permit icmp source 10.0.0.0 0.255.255.255 [HP-acl-adv-3000] rule 1 deny ip source 172.16.0.0 0.15.255.255 [HP-acl-adv-3000] rule 2 deny ip source 192.168.0.0 0.0.255.255 [HP-acl-adv-3000] rule 3 deny ip source 169.254.0.0 0.0.255.255 [HP-acl-adv-3000] rule 6 deny ip source 127.0.0.0 0.255.255.255 [HP] interface Vlan-interface 192 [HP-Vlan-interface192] packet-filter 3000 inbound

The HP FlexFabric Switch must display the Standard Mandatory DoD Notice and Consent Banner before granting access to the device.
Discussion
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, Executive Orders, directives, policies, regulations, standards, and guidance. System use notifications are required only for access via logon interfaces with human users.

If such a banner is not presented, this is a finding.
The HP FlexFabric Switch must retain the Standard Mandatory DoD Notice and Consent Banner on the screen until the administrator acknowledges the usage conditions and takes explicit actions to log on for further access.
Discussion
The banner must be acknowledged by the administrator prior to allowing the administrator access to the HP FlexFabric Switch. This provides assurance that the administrator has seen the message and accepted the conditions for access. If the consent banner is not acknowledged by the administrator, DoD will not be in compliance with system use notifications required by law. To establish acceptance of the network administration policy, a click-through banner at management session logon is required. The device must prevent further activity until the administrator executes a positive action to manifest agreement by clicking on a box indicating "OK".

The HP FlexFabric Switch must protect against an individual (or process acting on behalf of an individual) falsely denying having performed organization-defined actions to be covered by non-repudiation.
Discussion
This requirement supports non-repudiation of actions taken by an administrator and is required in order to maintain the integrity of the configuration management process. All configuration changes to the HP FlexFabric Switch are logged, and administrators authenticate with two-factor authentication before gaining administrative access. Together, these processes will ensure the administrators can be held accountable for the configuration changes they implement. To meet this requirement, the HP FlexFabric Switch must log administrator access and activity.

The HP FlexFabric Switch must provide audit record generation capability for DoD-defined auditable events within the HP FlexFabric Switch.
Discussion
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 records can be generated from various components within the HP FlexFabric Switch (e.g., process, module). Certain specific device functionalities may be audited as well. The list of audited events is the set of events for which audits are to be generated. This set of events is typically a subset of the list of all events for which the system is capable of generating audit records. DoD has defined the list of events for which the device will provide an audit record generation capability as the following: (i) Successful and unsuccessful attempts to access, modify, or delete privileges, security objects, security levels, or categories of information (e.g., classification levels); (ii) Access actions, such as successful and unsuccessful logon attempts, privileged activities or other system level access, starting and ending time for user access to the system, concurrent logons from different workstations, successful and unsuccessful accesses to objects, all program initiations, and all direct access to the information system; and (iii) All account creation, modification, disabling, and termination actions.

The HP FlexFabric Switch must generate audit records containing the full-text recording of privileged commands.
Discussion
Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information. Organizations consider limiting the additional audit information to only that information explicitly needed for specific audit requirements. The additional information required is dependent on the type of information (i.e., sensitivity of the data and the environment within which it resides). At a minimum, the organization must audit full-text recording of privileged commands. The organization must maintain audit trails in sufficient detail to reconstruct events to determine the cause and impact of compromise.

The HP FlexFabric Switch must use internal system clocks to generate time stamps for audit records.
Discussion
In order to determine what is happening within the network infrastructure or to resolve and trace an attack, the HP FlexFabric Switch must support the organization's capability to correlate the audit log data from multiple network devices to acquire a clear understanding of events. In order to correlate auditable events, time stamps are needed on all of the log records. If the internal clock is not used, the system may not be able to provide time stamps for log messages. Additionally, externally generated time stamps may not be accurate. Applications can use the capability of an operating system or purpose-built module for this purpose. (Note that the internal clock is required to be synchronized with authoritative time sources by other requirements.)

The HP FlexFabric Switch must protect audit information from any type of unauthorized read access.
Discussion
Audit information includes all information (e.g., audit records, audit settings, and audit reports) needed to successfully audit information system activity. If audit data were to become compromised, then competent forensic analysis and discovery of the true source of potentially malicious system activity is difficult, if not impossible, to achieve. In addition, access to audit records provides information an attacker could use to his or her advantage. To ensure the veracity of audit data, the information system and/or the HP FlexFabric Switch must protect audit information from any and all unauthorized read access. This requirement can be achieved through multiple methods which will depend upon system architecture and design. Commonly employed methods for protecting audit information include least privilege permissions as well as restricting the location and number of log file repositories. Additionally, network devices with user interfaces to audit records should not allow for the unfettered manipulation of or access to those records via the device interface. If the device provides access to the audit data, the device becomes accountable for ensuring audit information is protected from unauthorized access.

The HP FlexFabric Switch must protect audit information from unauthorized modification.
Discussion
Audit information includes all information (e.g., audit records, audit settings, and audit reports) needed to successfully audit network device activity. If audit data were to become compromised, then forensic analysis and discovery of the true source of potentially malicious system activity is impossible to achieve. To ensure the veracity of audit data, the HP FlexFabric Switch must protect audit information from unauthorized modification. This requirement can be achieved through multiple methods, which will depend upon system architecture and design. Some commonly employed methods include ensuring log files receive the proper file system permissions and limiting log data locations. Network devices providing a user interface to audit data will leverage user permissions and roles identifying the user accessing the data and the corresponding rights that the user enjoys in order to make access decisions regarding the modification of audit data.

The HP FlexFabric Switch 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.
Discussion
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 HP FlexFabric Switch 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 HP FlexFabric Switch must disable identifiers (individuals, groups, roles, and devices) after 35 days of inactivity.
Discussion
Inactive identifiers pose a risk to network devices. Attackers that are able to exploit an inactive identifier can potentially obtain and maintain undetected access to the device. Owners of inactive accounts will not notice if unauthorized access to their account has been obtained. Network devices need to track periods of inactivity and disable application identifiers after 35 days of inactivity.

The HP FlexFabric Switch must enforce a minimum 15-character password length.
Discussion
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 need 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.

The HP FlexFabric Switch must enforce 24 hours/1 day as the minimum password lifetime.
Discussion
Enforcing a minimum password lifetime helps prevent repeated password changes to defeat the password reuse or history enforcement requirement. Restricting this setting limits the user's ability to change their password. Passwords need to be changed at specific policy-based intervals; however, if the HP FlexFabric Switch allows the user to immediately and continually change their password, then the password could be repeatedly changed in a short period of time to defeat the organization's policy regarding password reuse.

The HP FlexFabric Switch must enforce a 60-day maximum password lifetime restriction.
Discussion
Any password, no matter how complex, can eventually be cracked. Therefore, passwords need to be changed at specific intervals. One method of minimizing this risk is to use complex passwords and periodically change them. If the HP FlexFabric Switch does not limit the lifetime of passwords and force users to change their passwords, there is the risk that the passwords could be compromised. This requirement does not include emergency administration accounts which are meant for access to the HP FlexFabric Switch in case of failure. These accounts are not required to have maximum password lifetime restrictions.

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.
Discussion
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 entity represented via a public key and associated data. It is used in the context of public key infrastructures, X.509 digital certificates, and DNSSEC. When there is a chain of trust, usually the top entity to be trusted becomes the trust anchor; it can be, for example, a Certification Authority (CA). A certification path starts with the subject certificate and proceeds through a number of intermediate certificates up to a trusted root certificate, typically issued by a trusted CA. This requirement verifies that a certification path to an accepted trust anchor is used for certificate validation and that the path includes status information. Path validation is necessary for a relying party to make an informed trust decision when presented with any certificate not already explicitly trusted. Status information for certification paths includes certificate revocation lists or online certificate status protocol responses. Validation of the certificate status information is out of scope for this requirement.

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.
Discussion
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.

The HP FlexFabric Switch must automatically audit account enabling actions.
Discussion
Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply enable a new or disabled account. Notification of account enabling is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail which documents the creation of application user accounts and notifies administrators and Information System Security Officers (ISSO).

The HP FlexFabric Switch must generate an immediate alert for account enabling actions.
Discussion
Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply enable a new or disabled account. Notification of account enabling is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail which documents the creation of application user accounts and notifies administrators and ISSOs. Such a process greatly reduces the risk that accounts will be surreptitiously enabled and provides logging that can be used for forensic purposes. In order to detect and respond to events that affect network administrator accessibility and device processing, network devices must audit account enabling actions and, as required, notify the appropriate individuals so they can investigate the event.

If the HP FlexFabric Switch uses discretionary access control, the HP FlexFabric Switch must enforce organization-defined discretionary access control policies over defined subjects and objects.
Discussion
Discretionary Access Control (DAC) is based on the notion that individual network administrators are "owners" of objects and therefore have discretion over who should be authorized to access the object and in which mode (e.g., read or write). Ownership is usually acquired as a consequence of creating the object or via specified ownership assignment. DAC allows the owner to determine who will have access to objects they control. An example of DAC includes user-controlled file permissions. When discretionary access control policies are implemented, subjects are not constrained with regard to what actions they can take with information for which they have already been granted access. Thus, subjects that have been granted access to information are not prevented from passing (i.e., the subjects have the discretion to pass) the information to other subjects or objects. A subject that is constrained in its operation by Mandatory Access Control policies is still able to operate under the less rigorous constraints of this requirement. Thus, while Mandatory Access Control imposes constraints preventing a subject from passing information to another subject operating at a different sensitivity level, this requirement permits the subject to pass the information to any subject at the same sensitivity level. The policy is bounded by the information system boundary. Once the information is passed outside of the control of the information system, additional means may be required to ensure the constraints remain in effect. While the older, more traditional definitions of discretionary access control require identity-based access control, that limitation is not required for this use of discretionary access control. The discretionary access control policies and the subjects and objects are defined uniquely for each network device, so they cannot be specified in the requirement.

If the HP FlexFabric Switch uses role-based access control, the HP FlexFabric Switch must enforce organization-defined role-based access control policies over defined subjects and objects.
Discussion
Organizations can create specific roles based on job functions and the authorizations (i.e., privileges) to perform needed operations on organizational information systems associated with the organization-defined roles. When administrators are assigned to the organizational roles, they inherit the authorizations or privileges defined for those roles. RBAC simplifies privilege administration for organizations because privileges are not assigned directly to every administrator (which can be a significant number of individuals for mid- to large-size organizations) but are instead acquired through role assignments. RBAC can be implemented either as a mandatory or discretionary form of access control. The RBAC policies and the subjects and objects are defined uniquely for each network device, so they cannot be specified in the requirement.

Administrators need to be aware of activity that occurs regarding their account. Providing them with information deemed important by the organization may aid in the discovery of unauthorized access or thwart a potential attacker.

The HP FlexFabric Switch must allocate audit record storage capacity in accordance with organization-defined audit record storage requirements.
Discussion
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 record storage capacity is usually performed during initial device setup if it is modifiable. The value for the organization-defined audit record storage requirement will depend on the amount of storage available on the HP FlexFabric Switch, the anticipated volume of logs, the frequency of transfer from the HP FlexFabric Switch to centralized log servers, and other factors.

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. Sources outside of the configured acceptable allowance (drift) may be inaccurate.

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.
Discussion
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. Organizations should consider setting time periods for different types of systems (e.g., financial, legal, or mission-critical systems). Organizations should also consider endpoints that may not have regular access to the authoritative time server (e.g., mobile, teleworking, and tactical endpoints). This requirement is related to the comparison done every 24 hours in CCI-001891 because a comparison must be done in order to determine the time difference. The organization-defined time period will depend on multiple factors, most notably the granularity of time stamps in audit logs. For example, if time stamps only show to the nearest second, there is no need to have accuracy of a tenth of a second in clocks.

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.
Discussion
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. The HP FlexFabric Switch must utilize an authoritative time server and/or be configured to use redundant authoritative time sources. This requirement is related to the comparison done in CCI-001891. 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 than the primary time source.

The HP FlexFabric Switch must protect against or limit the effects of all known types of Denial of Service (DoS) attacks on the HP FlexFabric Switch management network by employing organization-defined security safeguards.
Discussion
DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity. This requirement addresses the configuration of network devices to mitigate the impact of DoS attacks that have occurred or are ongoing on device availability. For each network device, known and potential DoS attacks must be identified and solutions for each type implemented. A variety of technologies exist to limit or, in some cases, eliminate the effects of DoS attacks (e.g., limiting processes or restricting the number of sessions the device opens at one time). Employing increased capacity and bandwidth, combined with service redundancy, may reduce the susceptibility to some DoS attacks. The security safeguards cannot be defined at the DoD level because they vary according to the capabilities of the individual network devices and the security controls applied on the adjacent networks (for example, firewalls performing packet filtering to block DoS attacks).

If the HP FlexFabric Switch uses mandatory access control, the HP FlexFabric Switch must enforce organization-defined mandatory access control policies over all subjects and objects.
Discussion
Mandatory access control policies constrain what actions subjects can take with information obtained from data objects for which they have already been granted access, thus preventing the subjects from passing the information to unauthorized subjects and objects. This class of mandatory access control policies also constrains what actions subjects can take with respect to the propagation of access control privileges; that is, a subject with a privilege cannot pass that privilege to other subjects. Enforcement of mandatory access control is typically provided via an implementation that meets the reference monitor concept. The reference monitor enforces (mediates) access relationships between all subjects and objects based on privilege and need to know. The mandatory access control policies are defined uniquely for each network device, so they cannot be specified in the requirement. An example of where mandatory access control may be needed is to prevent administrators from tampering with audit objects.

The HP FlexFabric Switch must notify the administrator of the number of successful logon attempts occurring during an organization-defined time period.
Discussion
Administrators need to be aware of activity that occurs regarding their network device management account. Providing administrators with information regarding the date and time of their last successful logon allows the administrator to determine if any unauthorized activity has occurred. This incorporates all methods of logon including, but not limited to, SSH, HTTP, HTTPS, and physical connectivity. The organization-defined time period is dependent on the frequency with which administrators typically log on to the HP FlexFabric Switch.

The HP FlexFabric Switch must generate audit log events for a locally developed list of auditable events.
Discussion
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.

The HP FlexFabric Switch must enforce access restrictions associated with changes to the system components.
Discussion
Changes to the hardware or software components of the HP FlexFabric Switch can have significant effects on the overall security of the network. Therefore, only qualified and authorized individuals should be allowed administrative access to the HP FlexFabric Switch for implementing any changes or upgrades. This requirement applies to updates of the application files, configuration, ACLs, and policy filters.

The HP FlexFabric Switch must support organizational requirements to conduct backups of system level information contained in the information system when changes occur or weekly, whichever is sooner.
Discussion
System-level information includes default and customized settings and security attributes, including ACLs that relate to the HP FlexFabric Switch configuration, as well as software required for the execution and operation of the device. Information system backup is a critical step in ensuring system integrity and availability. If the system fails and there is no backup of the system-level information, a denial of service condition is possible for all who utilize this critical network component. This control requires the HP FlexFabric Switch to support the organizational central backup process for system-level information associated with the HP FlexFabric Switch. This function may be provided by the HP FlexFabric Switch itself; however, the preferred best practice is a centralized backup rather than each network device performing discrete backups.

The HP FlexFabric Switch must employ automated mechanisms to assist in the tracking of security incidents.
Discussion
Despite the investment in perimeter defense technologies, enclaves are still faced with detecting, analyzing, and remediating network breaches and exploits that have made it past the HP FlexFabric Switch. An automated incident response infrastructure allows network operations to immediately react to incidents by identifying, analyzing, and mitigating any network device compromise. Incident response teams can perform root cause analysis, determine how the exploit proliferated, and identify all affected nodes, as well as contain and eliminate the threat. The HP FlexFabric Switch assists in the tracking of security incidents by logging detected security events. The audit log and network device application logs capture different types of events. The audit log tracks audit events occurring on the components of the HP FlexFabric Switch. The application log tracks the results of the HP FlexFabric Switch content filtering function. These logs must be aggregated into a centralized server and can be used as part of the organization's security incident tracking and analysis.

The HP FlexFabric switch must be configured to utilize an authentication server for the purpose of authenticating privilege users, managing accounts, and to centrally verify authentication settings and Personal Identity Verification (PIV) credentials.
Discussion
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. Protecting access authorization information ensures that authorization information cannot be altered, spoofed, or otherwise compromised during transmission. 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.

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.
Discussion
Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply create a new account. Notification of account creation is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail which documents the creation of accounts and notifies administrators and Information System Security Officers (ISSOs). Such a process greatly reduces the risk that accounts will be surreptitiously created and provides logging that can be used for forensic purposes.

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.
Discussion
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 a critical security monitoring and prevention function. Upon detecting a failure of network device security components, the HP FlexFabric Switch must activate a system alert message, send an alarm, or shut down. By immediately displaying an alarm message, potential security violations can be identified more quickly even when administrators are not logged on to the device. This can be facilitated by the switch sending SNMP traps to the SNMP manager that can then have the necessary action taken by automatic or operator intervention.
