Tanium 7.x Operating System on TanOS Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The Tanium Operating System (TanOS) must use multifactor authentication for network access to privileged accounts.

    Without the use of multifactor authentication, the ease of access to privileged functions is greatly increased. Multifactor authentication requires using two or more factors to achieve authentica...
    Rule High Severity
  • The Tanium Operating System (TanOS) must use FIPS-validated SHA-2 or higher hash function to protect the integrity of hash message authentication code (HMAC), Key Derivation Functions (KDFs), Random Bit Generation, and hash-only applications.

    To protect the integrity of the authenticator and authentication mechanism used for the cryptographic module used by the network device, the application, operating system, or protocol must be confi...
    Rule Medium Severity
  • The Tanium Operating System (TanOS) must terminate all sessions and network connections when nonlocal maintenance is completed.

    Terminating an idle SSH 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 por...
    Rule Medium Severity
  • Tanium Operating System (TanOS) must terminate all network connections associated with a communications session at the end of the session, or as follows: For in-band management sessions (privileged sessions), the session must be terminated after 10 minutes of inactivity; for user sessions (nonprivileged session), the session must be terminated after 15 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 th...
    Rule Medium Severity
  • The Tanium Operating System (TanOS) must notify the ISSO and ISSM of failed security verification tests.

    If personnel are not notified of failed security verification tests, they will not be able to take corrective action and the unsecure condition(s) will remain. Security function is defined as the h...
