    SV-230943r615886_rule FORE-NM-000150 CCI-001851 LOW The Forescout must configure a remote syslog where audit records are stored on a centralized logging target that is different from the system being audited. 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.
    SV-230944r615886_rule FORE-NM-000160 CCI-000366 MEDIUM Forescout must be configured to synchronize internal information system clocks 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 functions. Multiple time sources provide redundancy by i
    SV-230945r615886_rule FORE-NM-000170 CCI-001890 MEDIUM Forescout must be configured to use Coordinated Universal Time (UTC). 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
    SV-230946r615886_rule FORE-NM-000190 CCI-001812 MEDIUM Forescout must prohibit installation of software without explicit privileged permission by only authorized individuals. Allowing anyone to install software, without explicit privileges, creates the risk that untested or potentially malicious software will be installed on the system. This requirement applies to code changes and upgrades for all network devices.
    SV-230947r615886_rule FORE-NM-000200 CCI-001813 MEDIUM Forescout must enforce access restrictions associated with changes to device configuration.

    SV-230961r615886_rule FORE-NM-000350 CCI-001967 HIGH Forescout must be configured to authenticate SNMP messages using a FIPS-validated Keyed-Hash Message Authentication Code (HMAC). 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 gre
    SV-230962r615886_rule FORE-NM-000361 CCI-001967 MEDIUM Before establishing a connection with a Network Time Protocol (NTP) server, Forescout must authenticate using a bidirectional, cryptographically based authentication method that uses a FIPS-validated Advanced Encryption Standard (AES) cipher block algorithm to authenticate with the NTP server. 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.
    SV-230963r615886_rule FORE-NM-000370 CCI-000192 MEDIUM Forescout must enforce password complexity by requiring that at least one uppercase character be used. Use of a complex passwords helps to increase the time and resources required to compromise the password.

    SV-230968r615886_rule FORE-NM-000420 CCI-000195 LOW Forescout must require that when a password is changed, the characters are changed in at least eight of the positions within the password. If the application allows the user to consecutively reuse extensive portions of passwords, this increases the chances of password compromise by increasing the window of opportunity for attempts at guessing and brute-force attacks. The number of changed c
    SV-230969r615886_rule FORE-NM-000430 CCI-000803 HIGH Forescout must use FIPS 140-2 approved algorithms for authentication to a cryptographic module. 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
    SV-230970r615886_rule FORE-NM-000440 CCI-001133 HIGH Forescout 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. 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 terminat
