<GroupDescription></GroupDescription>
The Tanium application must be configured to send audit records from multiple components within the system to a central location for review and analysis.
Medium Severity
<VulnDiscussion>Successful incident response and auditing relies on timely, accurate system information and analysis to allow the organization to identify and respond to potential incidents in a proficient manner. If the application does not provide the ability to centrally review the application logs, forensic analysis is negatively impacted. Segregation of logging data to multiple disparate computer systems is counterproductive and makes log analysis and log event alarming difficult to implement and manage, particularly when the system or application has multiple logging components written to different locations or systems. Automated mechanisms for centralized reviews and analyses include, for example, security information and event management (SIEM) products.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Tanium Client processes must be excluded from On-Access scan.
Medium Severity
<VulnDiscussion>Similar to any other host-based applications, the Tanium Client is subject to the restrictions other system-level software may place on an operating environment. Antivirus, intrusion prevention system (IPS), encryption, or other security and management stack software may disallow the Client from working as expected.

1 Rule
<GroupDescription></GroupDescription>
The Tanium application must uniquely identify and authenticate nonorganizational users (or processes acting on behalf of nonorganizational users).
Medium Severity
<VulnDiscussion>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 compromise resources within the application or information system. Nonorganizational users include all information system users other than organizational users, which includes organizational employees or individuals the organization deems to have equivalent status of employees (e.g., contractors and guest researchers). Nonorganizational users must be uniquely identified and authenticated for all accesses other than those accesses explicitly identified and documented by the organization when related to the use of anonymous access, such as accessing a web server.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
SRG-APP-000211
1 Rule
<GroupDescription></GroupDescription>
The Tanium application must separate user functionality (including user interface services) from information system management functionality.
Medium Severity
<VulnDiscussion>Application management functionality includes functions necessary for administration and requires privileged user access. Allowing nonprivileged users to access application management functionality capabilities increases the risk that nonprivileged users may obtain elevated privileges. The separation of user functionality from information system management functionality is either physical or logical and is accomplished by using different computers, different central processing units, different instances of the operating system, different network addresses, different TCP/UDP ports, virtualization techniques, combinations of these methods, or other methods as appropriate. An example of this type of separation is observed in web administrative interfaces that use separate authentication methods for users of any other information system resources. This may include isolating the administrative interface on a different security domain and with additional access controls.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
The Tanium Server and Client applications must have logging enabled.
Medium Severity
<VulnDiscussion>Failure to a known state can address safety or security in accordance with the mission/business needs of the organization. Failure to a known secure state helps prevent a loss of confidentiality, integrity, or availability in the event of a failure of the information system or a component of the system. Preserving application state information helps to facilitate application restart and return to the operational mode of the organization with less disruption to mission-essential processes.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
The Tanium application must restrict the ability of individuals to use information systems to launch organization-defined denial-of-service (DoS) attacks against other information systems.
Medium Severity
<VulnDiscussion>The Tanium Action Approval feature provides a two-person integrity control mechanism designed to achieve a high level of security and reduce the possibility of error for critical operations and DoS conditions. When this feature is enabled, an action configured by one Tanium console user will require a second Tanium console user with a role of Action Approver (or higher) to approve the action before it is deployed to targeted computers.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
The Tanium application must manage bandwidth throttles to limit the effects of information flooding types of denial-of-service (DoS) attacks.
Medium Severity
<VulnDiscussion>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 of application DoS attacks, care must be taken when designing the application to ensure the application makes the best use of system resources. SQL queries have the potential to consume large amounts of CPU cycles if they are not tuned for optimal performance. Web services containing complex calculations requiring large amounts of time to complete can bog down if too many requests for the service are encountered within a short period of time. The methods employed to meet this requirement will vary depending on the technology the application uses. However, a variety of technologies exist to limit or, in some cases, eliminate the effects of application-related DoS attacks. Employing increased capacity and bandwidth combined with specialized application layer protection devices and service redundancy may reduce the susceptibility to some DoS attacks.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
The Tanium application must generate error messages that provide information necessary for corrective actions without revealing information that could be exploited by adversaries.
Medium Severity
<VulnDiscussion>Any application providing too much information in error messages risks compromising the data and security of the application and system. The structure and content of error messages must be carefully considered by the organization and development team. Organizations carefully consider the structure/content of error messages. The extent to which information systems are able to identify and handle error conditions is guided by organizational policy and operational requirements. Information that could be exploited by adversaries includes, for example, erroneous logon attempts with passwords entered by mistake as the username, mission/business information that can be derived from (if not stated explicitly by) information recorded, and personal information, such as account numbers, Social Security numbers, and credit card numbers.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
The Tanium application must reveal error messages only to the information system security officer (ISSO), information system security manager (ISSM), and system administrator (SA).
Medium Severity
<VulnDiscussion>Only authorized personnel must be aware of errors and the details of the errors. Error messages are an indicator of an organization's operational state or can identify the application. Additionally, personally identifiable information (PII) and operational information must not be revealed through error messages to unauthorized personnel or their designated representatives. The structure and content of error messages must be carefully considered by the organization and development team. The extent to which the information system is able to identify and handle error conditions is guided by organizational policy and operational requirements.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
The Tanium application must allocate audit record storage capacity in accordance with organization-defined audit record storage requirements.
Medium Severity
<VulnDiscussion>To ensure applications have a sufficient storage capacity in which to write the audit logs, applications must be able to allocate audit record storage capacity. The task of allocating audit record storage capacity is usually performed during initial installation of the application and is closely associated with the database administrator and system administrator roles. The database administrator or system administrator will usually coordinate the allocation of physical drive space with the application owner/installer, and the application will prompt the installer to provide the capacity information, the physical location of the disk, or both.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
The Tanium application must provide an immediate real-time alert to the system administrator and information system security officer, at a minimum, of all audit failure events requiring real-time alerts.
Medium Severity
<VulnDiscussion>It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability, and system operation may be adversely affected. Alerts provide organizations with urgent messages. Real-time alerts provide these messages immediately (i.e., the time from event detection to alert occurs in seconds or less).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
SRG-APP-000378
1 Rule
<GroupDescription></GroupDescription>
The Tanium application must prohibit user installation of software without explicit privileged status.
Medium Severity
<VulnDiscussion>Allowing regular users to install software, without explicit privileges, creates the risk that untested or potentially malicious software will be installed on the system. Explicit privileges (escalated or administrative privileges) provide the regular user with explicit capabilities and control that exceeds the rights of a regular user. Application functionality will vary, and while users are not permitted to install unapproved applications, there may be instances where the organization allows the user to install approved software packages, such as from an approved software repository. The application must enforce software installation by users based on what types of software installations are permitted (e.g., updates and security patches to existing software) and what types of installations are prohibited (e.g., software whose pedigree with regard to being potentially malicious is unknown or suspect) by the organization. This requirement applies, for example, to applications that provide the ability to extend application functionality (e.g., plug-ins, add-ons) and software management applications.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
The application must enforce access restrictions associated with changes to application configuration.
Medium Severity
<VulnDiscussion>Failure to provide logical access restrictions associated with changes to application configuration may have significant effects on the overall security of the system. When dealing with access restrictions pertaining to change control, any changes to the hardware, software, and/or firmware components of the information system and/or application can have significant effects on the overall security of the system. Accordingly, only qualified and authorized individuals should be allowed to obtain access to application components to initiate changes, including upgrades and modifications. Logical access restrictions include, for example, controls that restrict access to workflow automation, media libraries, abstract layers (e.g., changes implemented into third-party interfaces rather than directly into information systems), and change windows (e.g., changes occur only during specified times, making unauthorized changes easy to discover).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
The application must employ a deny-all, permit-by-exception (allowlist) policy to allow the execution of authorized software programs.
Medium Severity
<VulnDiscussion>Using an allowlist provides a configuration management method for allowing the execution of only authorized software. Using only authorized software decreases risk by limiting the number of potential vulnerabilities. The organization must identify authorized software programs and permit execution of authorized software. The process used to identify software programs that are authorized to execute on organizational information systems is commonly referred to as allowlisting. Verification of allowlisted software can occur either prior to execution or at system startup. This requirement applies to configuration management applications or similar types of applications designed to manage system processes and configurations (e.g., HBSS and software wrappers).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Tanium application must accept Personal Identity Verification (PIV) credentials from other federal agencies.
Medium Severity
<VulnDiscussion>Access may be denied to authorized users if federal agency PIV credentials are not accepted. PIV credentials are issued by federal agencies and conform to FIPS Publication 201 and supporting guidance documents. OMB Memorandum 11-11 requires federal agencies to continue implementing the requirements specified in HSPD-12 to enable agencywide use of PIV credentials.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
The Tanium application must install security-relevant software updates within the time period directed by an authoritative source (e.g., IAVM, CTOs, DTMs, and STIGs).
Medium Severity
<VulnDiscussion>Security flaws with software applications are discovered daily. Vendors are constantly updating and patching their products to address newly discovered security vulnerabilities. Organizations (including any contractor to the organization) are required to promptly install security-relevant software updates (e.g., patches, service packs, and hot fixes). Flaws discovered during security assessments, continuous monitoring, incident response activities, or information system error handling must also be addressed expeditiously. Organization-defined time periods for updating security-relevant software may vary based on a variety of factors including, for example, the security category of the information system or the criticality of the update (i.e., severity of the vulnerability related to the discovered flaw). This requirement will apply to software patch management solutions that are used to install patches across the enclave and also to applications that are not part of that patch management solution. For example, many browsers can install their own patch software. Patch criticality, as well as system criticality, will vary. Therefore, the tactical situations regarding the patch management process will also vary. This means the time period used must be a configurable parameter. Time frames for application of security-relevant software updates may depend on the Information Assurance Vulnerability Management (IAVM) process. The application will be configured to check for and install security-relevant software updates within an identified time period from the availability of the update. The specific time period will be defined by an authoritative source (e.g., IAVM, CTOs, DTMs, and STIGs).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
Tanium must alert the ISSO, ISSM, and other individuals designated by the local organization when the following Indicators of Compromise (IOCs) or potential compromise are detected: real-time intrusion detection; threats identified by authoritative sources (e.g., CTOs); and Category I, II, IV, and VII incidents in accordance with CJCSM 6510.01B.
Medium Severity
<VulnDiscussion>When a security event occurs, the application that has detected the event must immediately notify the appropriate support personnel so they can respond appropriately. Alerts may be generated from a variety of sources, including audit records or inputs from malicious code protection mechanisms, intrusion detection, or prevention mechanisms. Alerts may be transmitted, for example, telephonically, by electronic mail messages, or by text messaging. Individuals designated by the local organization to receive alerts may include, for example, system administrators, mission/business owners, or system owners. IOCs are forensic artifacts from intrusions that are identified on organizational information systems (at the host or network level). IOCs provide organizations with valuable information on objects or information systems that have been compromised. These indicators reflect the occurrence of a compromise or a potential compromise. This requirement applies to applications that provide monitoring capability for unusual/unauthorized activities including but are not limited to host-based intrusion detection, antivirus, and malware applications.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Tanium application must authenticate endpoint devices (servers) before establishing a local, remote, and/or network connection using bidirectional authentication that is cryptographically based.
Medium Severity
<VulnDiscussion>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, such as remote connections. This requires device-to-device authentication. Information systems must use IEEE 802.1x, Extensible Authentication Protocol [EAP], Radius server with EAP-Transport Layer Security [TLS] authentication, or Kerberos to identify/authenticate devices on local and/or wide area networks.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Tanium endpoint must have the Tanium Server's pki.db in its installation.
Medium Severity
<VulnDiscussion>Without cryptographic integrity protections in the Tanium Client, information could be altered by unauthorized users without detection. Cryptographic mechanisms used for protecting the integrity of Tanium communications information include signed hash functions using asymmetric cryptography, enabling distribution of the public key to verify the hash information while maintaining the confidentiality of the secret key used to generate the hash.

Access to Tanium logs on each endpoint must be restricted by permissions.
Medium Severity
<VulnDiscussion>For the Tanium Client software to run without impact from external negligent or malicious changes, the permissions on the Tanium log files and their directory must be restricted. Tanium is deployed with a Client Hardening Solution. This solution, when applied, will ensure directory permissions are in place.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

<GroupDescription></GroupDescription>
The Tanium cryptographic signing capabilities must be enabled on the Tanium Clients to safeguard the authenticity of communications sessions when answering requests from the Tanium Server.
Medium Severity
<VulnDiscussion>All of Tanium's signing capabilities should be enabled upon install. Tanium supports the cryptographic signing and verification before execution of all Sensors, Questions, Actions, Sensor Libraries, File Shards, etc. Enabling signing removes the ability of an attacker to conduct man-in-the-middle (MitM) attacks for remote code execution and precludes the modification of the aforementioned data elements in transit. Additionally, Tanium supports object-level signing for content ingested into the Tanium platform. This allows for the detection and rejection of changes to objects (sensors, actions, etc.) by even a privileged user within Tanium. Tanium has built-in signing capabilities enabled by default when installed. Cryptographic signing and verification of all Sensors, Questions, Actions, Sensor Libraries, File Shards, etc., before execution will be enforced by Tanium. Signing will prevent MitM remote code execution attacks and will protect data element in transit. Tanium also supports object-level signing for content within the Tanium platform.

Firewall rules must be configured on the Tanium endpoints for client-to-server communications.
Medium Severity
<VulnDiscussion>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 configurations, proper TCP communications may not take place as necessary for application functionality. The Tanium environment can perform hundreds or thousands of times faster than other security or systems management tools because the Tanium Clients communicate in secure, linearly controlled peer-to-peer rings. Because clients dynamically communicate with other nearby agents based on proximity and latency, rings tend to form automatically to match a customer's topology. For example, endpoints in California will form one ring while endpoints in Germany will form a separate ring.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The ability to uninstall the Tanium Client service must be disabled on all managed clients.
Medium Severity
<VulnDiscussion>By default, end users have the ability to uninstall software on their clients. In the event the Tanium Client software is uninstalled, the Tanium Server is unable to manage the client and must redeploy to the client. Preventing the software from being displayed in the client's Add/Remove Programs will lessen the risk of the software being uninstalled by non-Tanium system administrators.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Tanium applications must be configured to filter audit records for events of interest based on organization-defined criteria.
Medium Severity
<VulnDiscussion>The ability to specify the event criteria that are of interest enables those reviewing the logs to quickly isolate and identify these events without having to review entries that are of little or no consequence to the investigation. Without this capability, forensic investigations are impeded. Events of interest can be identified by the content of specific audit record fields including, for example, identities of individuals, event types, event locations, event times, event dates, system resources involved, IP addresses involved, or information objects accessed. Organizations may define audit event criteria to any degree of granularity required, for example, locations selectable by general networking location (e.g., by network or subnetwork) or by specific information system component. This requires applications to provide the capability to customize audit record reports based on organization-defined criteria.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Tanium cryptographic signing capabilities must be enabled on the Tanium Server.
Medium Severity
<VulnDiscussion>All of Tanium's signing capabilities should be enabled upon install. Tanium supports the cryptographic signing and verification before execution of all Sensors, Questions, Actions, Sensor Libraries, File Shards, etc. Enabling signing does away with the ability of an attacker to conduct man-in-the-middle (MitM) attacks for remote code execution and precludes the modification of the aforementioned data elements in transit. Additionally, Tanium supports object level signing for content ingested into the Tanium platform. This allows for the detection and rejection of changes to objects (sensors, actions, etc.) by even a privileged user within Tanium. Tanium has built-in signing capabilities enabled by default when installed. Cryptographic signing and verification of all Sensors, Questions, Actions, Sensor Libraries, File Shards, etc., before execution will be enforced by Tanium. Signing will prevent MitM remote code execution attacks and will protect data elements in transit. Tanium also supports object-level signing for content within the Tanium platform.

<VulnDiscussion>Changes to any software components can have significant effects on the overall security of the application. 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 that it has been provided by a trusted vendor. 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 that it has been provided by a trusted vendor. Self-signed certificates are disallowed by this requirement. The application 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 is from an approved certificate authority (CA).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Firewall rules must be configured on the Tanium Server for client-to-server communications.

<VulnDiscussion>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 configurations, proper TCP communications may not take place as necessary for application functionality. The Tanium environment can perform hundreds or thousands of times faster than other security or systems management tools because the Tanium Clients communicate in secure, linearly controlled peer-to-peer rings. Because clients dynamically communicate with other nearby agents based on proximity and latency, rings tend to form automatically to match a customer's topology. For example, endpoints in California will form one ring while endpoints in Germany will form a separate ring.

Applications 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.

<VulnDiscussion>Discretionary Access Control (DAC) is based on the notion that individual users 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 DAC 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.

This requirement addresses the configuration of applications to mitigate the impact of DoS attacks that have occurred or are ongoing on application availability. For each application, 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 application opens at one time). Employing increased capacity and bandwidth, combined with service redundancy, may reduce the susceptibility to some DoS attacks.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Tanium Server files must be excluded from host-based intrusion prevention intervention.
Medium Severity
<VulnDiscussion>Similar to any other host-based applications, the Tanium Server is subject to the restrictions other system-level software may place on an operating environment. Antivirus, intrusion prevention system (IPS), encryption, or other security and management stack software may disallow the Tanium Server from working as expected.

The Tanium application must set an inactive timeout for sessions.
Medium Severity
<VulnDiscussion>Leaving sessions open indefinitely is a major security risk. An attacker can easily use an already authenticated session to access the hosted application as the previously authenticated user. By closing sessions after a set period of inactivity, the web server can ensure sessions that are not closed when the user logs out of an application are eventually closed. Acceptable values are 5 minutes for high-value applications, 10 minutes for medium-value applications, and 20 minutes for low-value applications.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Tanium application service must be protected from being stopped by a nonprivileged user.
Medium Severity
<VulnDiscussion>Denial of service (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 applications to mitigate the impact of DoS attacks that have occurred or are ongoing on application availability. For each application, 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 application opens at one time). Employing increased capacity and bandwidth, combined with service redundancy, may reduce the susceptibility to some DoS attacks. A web server not properly tuned may become overwhelmed and cause a DoS condition even with expected traffic from users. To avoid a DoS, the web server must be tuned to handle the expected traffic for the hosted applications.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

The Tanium Application, SQL, and Module servers must all be configured to communicate using TLS 1.2 Strict Only.

The SchUseStrongCrypto registry value must be set.
High Severity
<VulnDiscussion>Without protection of the transmitted information, confidentiality and integrity may be compromised since unprotected communications can be intercepted and either read or altered. This requirement applies only to applications that are either distributed or can allow access to data nonlocally. Use of this requirement will be limited to situations where the data owner has a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process. When transmitting data, applications must leverage transmission protection mechanisms, such as TLS, SSL VPNs, or IPsec. FIPS 140-2 approved TLS versions must be enabled, and non-FIPS-approved SSL versions must be disabled. NIST SP 800-52 defines the approved TLS versions for government applications. Communication paths outside the physical protection of a controlled boundary are exposed to the possibility of interception and modification. Protecting the confidentiality and integrity of organizational information can be accomplished by physical means (e.g., employing physical distribution systems) or by logical means (e.g., employing cryptographic techniques). If physical means of protection are employed, then logical means (cryptography) do not have to be employed, and vice versa.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
