Tanium 7.x Application on TanOS Security Technical Implementation Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The Tanium application must prohibit user installation, modification, or deletion of software without explicit privileged status.

    Allowing regular users to install, modify, or delete software, without explicit privileges, creates the risk that the application performs in an inconsistent manner from its design. Explicit privil...
    Rule Medium Severity
  • Firewall rules must be configured on the Tanium Server for Client-to-Server communications.

    In addition to the client-to-server TCP communication that takes place over port 17472, Tanium Clients also communicate to other Tanium-managed computers over port 17472. Without proper firewall co...
    Rule Medium Severity
  • The Tanium Application Server must be configured to prohibit or restrict the use of organization-defined functions, ports, protocols, and/or services, as defined in the PPSM CAL and vulnerability assessments.

    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 or restr...
    Rule Medium Severity
  • The Tanium application must enforce a minimum 15-character password length.

    The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised. Password complexity, or strength, is a measure of the effectivene...
    Rule Medium Severity
  • The Tanium application must uniquely identify and authenticate nonorganizational users (or processes acting on behalf of nonorganizational users).

    Lack of authentication and identification enables nonorganizational users to gain access to the application or possibly other information systems and provides an opportunity for intruders to compro...
    Rule Medium Severity
  • The Tanium application must separate user functionality (including user interface services) from information system management functionality.

    Application management functionality includes functions necessary for administration and requires privileged user access. Allowing nonprivileged users to access application management functionality...
    Rule Medium Severity
  • The Tanium application must manage bandwidth throttles to limit the effects of information flooding types of Denial of Service (DoS) attacks.

    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. In the case...
    Rule Medium Severity
  • Tanium must notify system administrator (SA) and the information system security officer (ISSO) when accounts are created.

    Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of re-establishing access. One way to accomplish this is for the attacker to simpl...
    Rule Medium Severity
  • Tanium must notify system administrators (SAs) and the information system security officer (ISSO) for account disabling actions.

    When application accounts are disabled, user accessibility is affected. Accounts are utilized for identifying individual users or for identifying the application processes themselves. Sending notif...
    Rule Medium Severity
  • Tanium must notify system administrators (SAs) and the information system security officer (ISSO) for account removal actions.

    When application accounts are removed, user accessibility is affected. Accounts are utilized for identifying users or for identifying the application processes themselves. Sending notification of a...
