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 based on account type, role, or access type is helpful in limiting risks related to denial of service (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 must be defined based upon mission needs and the operational environment for each system. At a minimum, limits must be set for SSH, HTTPS, account of last resort, and root account sessions.
Checks: C-33860r603629_chk

Determine if Forescout requires a limit of one session per user. This requirement may be verified by demonstration or configuration review. 1. Log on to the Forescout Administrator UI. 2. From the menu, select Tools >> Options >> CounterAct user profiles >> Password and Sessions >> Session. 3. Verify the "allow only one login session per user", "Terminate existing session upon new login", and "Console and web portal sessions cannot exist concurrently". If Forescout does not enforce one session per user, this is a finding.

Fix: F-33833r603630_fix

Configure Forescout to require a limit of one session per user. 1. Log on to the Forescout Administrator UI. 2. From the menu, select Tools >> Options >> CounterAct user profiles >> Password and Sessions >> Session. 3. Check "allow only one login session per user". 4. Select the "Terminate existing session upon new login" radio button. 5. Select "Console and web portal sessions cannot exist concurrently".

b
Forescout must terminate the account of last resort password when members with access to the password leave the group.

A shared/group account credential is a shared form of authentication that allows multiple individuals to access the network device using a single account. If shared/group account credentials are not terminated when individuals leave the group, the user that left the group can still gain access even though they are no longer authorized. There may also be instances when specific user actions need to be performed on the network device without unique administrator identification or authentication. Examples of credentials include passwords and group membership certificates.
Checks: C-33861r603632_chk

Review the documentation to verify a procedure exists to change the account of last resort and root account password when users with knowledge of the password leave the group. If a procedure does not exist to change the account of last resort and root account password when users with knowledge of the password leave the group, this is a finding.

Fix: F-33834r603633_fix

Establish and document a procedure that requires the changing of the account of last resort and root account password when users with knowledge of the password leave the group. To change the password: 1. Log on to the Forescout Administrator UI. 2. From the menu, select Tools >> Options >> Console Preferences >> Password and Sessions. 3. Click the Password tab. 4. Click "User must change password at next logon if changed by admin user". Note: the next time the account of last resort is accessed, the user will be prompted to change their password. Note: Use of a cryptographically generated password is recommended. Password must be stored in a locked safe and used only when necessary since individual accounts are required to be used to ensure non-repudiation.

b
Forescout must be configured with only one web account and one CLI account of last resort with limited access and used only when 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 is down or connectivity between the device and the authentication server is not operable. This account is referred to as the "account of last resort" since it is intended to be used as a last resort and when immediate administrative access is absolutely necessary. The account of last resort logon credentials must be stored in a sealed envelope and kept in a safe. The safe must be periodically audited to verify the envelope remains sealed. The signature of the auditor and the date of the audit must be added to the envelope as a record. Administrators must secure the credentials and disable the root account (if possible) when not needed for system administration functions.
Checks: C-33862r603635_chk

Verify only one local account exists and that it has full administrator privileges. 1. Log on to the Forescout Administrator UI. 2. From the menu, select Tools >> Options >> CounterACT User Profiles. If local accounts in the CounterACT User profile or CLI exist other than the accounts of last resort, this is a finding.

Fix: F-33835r603636_fix

There are two default accounts. The CLIAdmin root account can only be used with the CLI. To access the CLI, an account must be created that only has access to the CLI. Accounts created in CounterACT user profile in the web management tools do not have access to login to the CLI. The default console account "Admin" allows access to the web management tool. These accounts can be used as the accounts of last resort or two other accounts may be created for this purpose as long as a strong password that meets DoD requirements is used for both. 1. Log on to the Forescout Administrator UI. 2. From the menu, select Tools >> Options >> CounterACT user profiles. Remove unauthorized local accounts not identified as the account of last resort.

b
Forescout must be configured to enforce the limit of three consecutive invalid logon attempts, after which time it must lock out the user account from accessing the device for 15 minutes.

By limiting the number of failed login attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced.
Checks: C-33863r603638_chk

Determine if Forescout is configured either to enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period, or to use an authentication server to perform this function. 1. Log on to the Forescout Administrator UI. 2. From the menu, select Tools >> Options >> CounterACT User Profiles >> Password and Sessions. 3. Verify the "Lock account after" radio button is selected. 4. Verify that "3" password failures for "15 minutes" is configured. If the limit of three consecutive invalid logon attempts by a user during a 15-minute time period is not enforced, this is a finding.

Fix: F-33836r603639_fix

Configure Forescout or its associated authentication server to enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period. 1. Log on to the Forescout Administrator UI. 2. From the menu, select Tools >> Options >> CounterACT User Profiles >> Password and Sessions. 3. Ensure the "Lock account after" radio button is selected. 4. Ensure that "3" password failures for "15" minutes is configured.

The banner must be acknowledged by the administrator prior to the device allowing the administrator access to the network device. 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. In the case of CLI access using a terminal client, entering the username and password when the banner is presented is considered an explicit action of acknowledgement. Entering the username, viewing the banner, then entering the password is also acceptable. The web management tool configuration setting works for both the CLI and the web management tool.
Checks: C-33865r615880_chk

Verify Forescout retains the Standard Mandatory DoD-approved Notice and Consent Banner on the screen until users acknowledge the usage conditions and takes explicit actions to log on for further access. Attempt to log on to the Forescout device as a system administrator using the web management tool. If Forescout does not retain the Standard Mandatory DoD-approved Notice and Consent Banner on the screen until users acknowledge the usage conditions and take explicit actions to log on for further access, this is a finding.

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 the source synchronizes time to a more accurate source. The network device 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.
Checks: C-33874r603671_chk

Determine if Forescout is configured to synchronize internal clocks with the organization's primary and secondary NTP servers. 1.

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. Time is commonly expressed in Coordinated Universal Time (UTC), a modern continuation of Greenwich Mean Time (GMT), or local time with an offset from UTC.
Checks: C-33875r603674_chk

Determine if Forescout records time stamps for log records that can be mapped to UTC. This requirement may be verified by demonstration or configuration review. Verify by connecting to the appliance via SSH using standard user/operator privilege. 1. Type "date" at the command prompt. 2. Verify the date references accurate time and "UTC" shows just before the year. If Forescout does not record time stamps for log records that can be mapped to UTC, this is a finding.

Fix: F-33848r603675_fix

Configure Forescout to record time stamps for log records that can be mapped to UTC. Note: Updating time preferences will force Forescout into maintenance mode and the service must be restarted. Use a scheduled outage for planned maintenance and stop Forescout service prior to adjusting time settings. 1. Type the following command at the prompt using the IP address of the required NTP server: fstool ntp <ip address> 2.

Changes to any software components can have significant effects on the overall security of the network device. Verifying software components have been digitally signed using a certificate that is recognized and approved by the organization ensures the software has not been tampered with and has been provided by a trusted vendor. Accordingly, patches, service packs, or application components must be signed with a certificate recognized and approved by the organization. Verifying the authenticity of the software prior to installation validates the integrity of the patch or upgrade received from a vendor. This ensures the software has not been tampered with and has been provided by a trusted vendor. Self-signed certificates are disallowed by this requirement. The device should not have to verify the software again. This requirement does not mandate DOD certificates for this purpose; however, the certificate used to verify the software must be from an approved Certificate Authority (CA). Customer portal updates file download section on the vendor website has the MD5 hashes for the updates files. Currently, this is the method used by DOD to pull down files rather than using the internal connection to the Forescout server.
Checks: C-33879r603686_chk

Verify by inspecting the SSP or documentation to determine if there is a procedure for validating the MD5 hash against the Forescout updates.forescout.com portal to ensure that the software has come from the Forescout server.

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. Forescout has three predefined user roles: Admin, Web Access, and Console User. The Admin role has access to all data and management functions. By default, the Console role has access to the management console and the Web role has access to the view-only portal. However, both roles may be assigned one or more permissions, each with its own set of privileges to the data and functions.

Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Bidirectional authentication provides stronger safeguards to validate the identity of other devices for connections that are of greater risk. A local connection is any connection with a device communicating without the use of a network. A network connection is any connection with a device that communicates through a network (e.g., local area or wide area network, internet). A remote connection is any connection with a device communicating through an external network (e.g., the internet). Because of the challenges of applying this requirement on a large scale, organizations are encouraged to only apply the requirement to those limited number (and type) of devices that truly need to support this capability.

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 affect scheduled actions. NTP authentication is used to prevent this tampering by authenticating the time source. Currently, AES block cipher algorithm is approved for use in DoD for both applying cryptographic protection (e.g., encryption) and removing or verifying the protection that was previously applied (e.g., decryption). NTP devices use MD5 authentication keys. The MD5 algorithm is not specified in either the FIPS or NIST recommendation. However, MD5 is preferred to no authentication at all. The trusted-key statement permits authenticating NTP servers. The product must be configured to support separate keys for each NTP server. Severs must have a PKI device certificate involved for use in the device authentication process. Configurable to use SHA-1 when SNMPv3 is configured which is recommended by the vendor and required by DoD. Vendor cautions that this may impact performance with other devices. Downgrade to not a finding if correctly configured.

Unapproved mechanisms used for authentication to the cryptographic module are not validated and therefore cannot be relied upon to provide confidentiality or integrity, and DoD data may be compromised. Network devices utilizing encryption are required to use FIPS-compliant mechanisms for authenticating to cryptographic modules. FIPS 140-2 is the current standard for validating that mechanisms used to access cryptographic modules utilize authentication that meets DoD requirements. However, authentication algorithms must configure security processes to use only FIPS-approved and NIST-recommended authentication algorithms.

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.
