Program Purpose: Develop and publish policies to protect the IRS against potential security threats, risks, and vulnerabilities to ensure compliance with federal mandates and legislation. Audience: The provisions in this manual apply to: All offices and business, operating, and functional units within the IRS. Individuals and organizations having contractual arrangements with the IRS, including employees, contractors, vendors, and outsourcing providers, who use or operate systems that store, process or transmit IRS information or connect to an IRS network or system. Policy Owner: Chief Information Officer Program Owner: Cybersecurity, Cybersecurity Threat Response and Remediation, an organization within Cybersecurity. Program Goals: To protect the confidentiality, integrity, and availability of IRS information and systems.

Background

10.8.2.1.1 (04-29-2025) Background IRM 10.8.2 has been aligned to the roles and responsibilities described in National Institute of Standards and Technology (NIST) Special Publication (SP) 800-100, Information Security Handbook: A Guide for Managers and SP 800-37 Revision 2, Risk Management Framework for Information Systems and Organizations: A System Life Cycle Approach for Security and Privacy IRM 10.8.2 is part of the IRM 10.8, Information Technology (IT) Security series for IRS IT Cybersecurity.

Authority

10.8.2.1.2 (04-29-2025) Authority All IRS systems and applications are required to comply with Executive Orders (EOs), Office of Management and Budget (OMB), Federal Information Security Modernization Act of 2014 (FISMA), NIST, Department of Homeland Security (DHS), Treasury, and IRS guidelines as they apply. Treasury Directive Publication (TD P) 85-01, Department of the Treasury Information Technology Security Program and federal regulations require senior management/executive officials establish an IT security program, which includes the identification of roles and responsibilities that support IT security.

Roles and Responsibilities

10.8.2.1.3 (04-29-2025) Roles and Responsibilities The IRS implements IT security roles and responsibilities to ensure the confidentiality, integrity, and availability of its systems, applications, and information. This IRM covers roles and responsibilities that support the IT security program. Note: Refer to IRM 10.5.1, Privacy and Information Protection, Privacy Policy, for a description of privacy roles and responsibilities. Although IRM 10.8.2 is intended to be the primary source for general IT security roles and responsibilities, all documents in the 10.8 series, additional applicable policy suites of IRMs and applicable business unit procedural guidance (e.g., standard operating procedures (SOP)) must be carefully reviewed for an individual to comprehensively understand their role and specific responsibilities in their environmental context. IRMs in the 10.8 series provide explicit requirements where security roles and responsibilities are delineated. Due to each document having its own update lifecycle, there may be instances where updated roles and responsibilities are published in supplementary policies which have not yet been added to this IRM. In those instances, the newer published roles and responsibilities must be implicitly followed along with those stated in this IRM.

Program Management and Review

10.8.2.1.4 (04-29-2025) Program Management and Review The IRS security policy program establishes a framework of controls to ensure the inclusion of security into the IRS IT environment. This framework is provided through the issuance of security policies via the IRM 10.8 series and the development of security requirements checklists. Stakeholders are notified when revisions to the security policies and security requirements checklists are made. It is the policy of the IRS to: Establish and manage an information security program within its organizations. This IRM provides uniform policies and guidance to be used by each organization. Protect all IT resources belonging to, or used by, the IRS at a level commensurate with the risk and magnitude of harm that could result from loss, misuse, or unauthorized access to that IT resource. Protect its information resources and allow the use, access, disposition, and disclosure of information in accordance with applicable laws, policies, federal regulations, OMB guidance, Treasury Directives (TDs), NIST Publications, National Archives and Records Administration (NARA) guidance, other regulatory guidance, and best practice methodologies. Use best practice methodologies (e.g., Capability Maturity Model Integration (CMMI), Information Technology Infrastructure Library (ITIL), and Lean Six Sigma (LSS)) to document and improve IRS IT process and service efficiency and effectiveness.

Program Controls

10.8.2.1.5 (11-07-2023) Program Controls Each IRM in the 10.8 series is assigned an author who reviews the IRM to ensure accuracy. The IRM authors continuously monitor federal guidance (e.g., OMB, Cybersecurity and Infrastructure Security Agency (CISA), NIST, DISA) for potential revisions to security policies and security requirements checklists. Revisions to security policies and checklists are reviewed by the security policy team, in collaboration with applicable stakeholders, for potential impact to the IRS operational environment. Security policy provides a report identifying security policies and security requirements checklists that have recently been revised or are in the revision process. For information systems that store, process, or transmit classified information, refer to IRM 10.9.1 , Classified National Security Information (CNSI), for guidance on protecting classified information. In the event there is a discrepancy between this IRM and IRM 10.8.1, Information Technology (IT) Security, Security Policy, IRM 10.8.1 has precedence, unless the security controls/requirements in this IRM are more restrictive.

Terms and Acronyms

10.8.2.1.6 (11-07-2023) Terms and Acronyms Refer to Exhibit 10.8.2-2, Terms and Acronyms for a list of terms, acronyms, and definitions.

Related Resources

10.8.2.1.7 (04-29-2025) Related Resources In addition to federal guidance cited throughout this IRM, this IRM incorporates IRS-defined policy, regulatory and mandated guidance, and policy from other sources. Refer to Exhibit 10.8.2-3, Related Resources for a list of related resources and references.

Risk Acceptance and Risk-Based Decisions (RBD)

10.8.2.2 (04-29-2025) Risk Acceptance and Risk-Based Decisions (RBD) Any exception to this IRM requires that the authorizing official (AO) make a risk acceptance decision. Users must submit risk-based decision (RBD) requests in accordance with Cybersecurity's Security Risk Management (SRM) risk acceptance process documented in the Request for Risk Acceptance and Risk Based Decision (RBD) standard operating procedures (SOP).

IT Security Roles and Responsibilities

10.8.2.3 (04-29-2025) IT Security Roles and Responsibilities This IRM establishes the IT security roles and responsibilities for the IRS. In accordance with IRM 10.8.1, the IRS must implement security roles and responsibilities in accordance with federal laws and IT security guidelines that are appropriate for specific operations and functions. The following roles and responsibilities are based on FISMA, NIST, and Department of the Treasury guidance and policies. Throughout this IRM, roles may be identified as being responsible for creating, updating, and maintaining documentation. This may be accomplished through agreements and coordination with other organizational entities. When this is done, it does not relieve the individual with the role of the responsibility, but rather requires effective communication between the two parties. The IRS must ensure there are no conflicts of interest when assigning the same individual to multiple risk management roles. [NIST: SP 800-37 | NIST: SP 800-100] Example: Authorizing officials cannot occupy the role of system owner or common control provider for systems or common controls they are authorizing. In addition, combining multiple roles for security and privacy requires care because the two disciplines may require different expertise, and in some circumstances, the priorities may be competing. Note: If a conflict of interest is unavoidable, only the agency head can formally waive the conflict of interest.

Key Governance and Related Roles & Responsibilities

10.8.2.3.1 (04-29-2025) Key Governance and Related Roles & Responsibilities There are several governance stakeholders common to most organizations that span the organization. These stakeholders include senior management/executive official, a chief information officer (CIO), information security personnel, and a chief financial officer (CFO), among others. The specific requirements of each role may differ with the degree of information security governance centralization or in response to the specific missions and needs of an organization. [NIST: SP 800-100] The following subsections provide functional roles and responsibilities for personnel who have security-related governance responsibility for the protection of information systems they operate, manage and support.

Database Administrator (DBA)

10.8.2.3.1.23 (11-27-2019) Database Administrator (DBA) Database administrators (DBAs) perform all activities related to maintaining a correctly performing and secure database environment. Responsibilities include design (in conjunction with application developers), implementation, and maintenance of the database system as described in IRM 10.8.21, Information Technology (IT) Security, Database Security Policy, and associated IRMs. The primary security role of any DBA is to administer and maintain database repositories for proper use by authorized individuals. Individuals assigned security responsibilities for database management system (DBMS) environments, including the security specialist (SecSpec) and DBA, must obtain database security technical training necessary to implement the requirements of this IRM. The training must cover the security features specific to the DBMS products the individuals are required to support. DBA role accounts have the least level of elevated privileges required to perform DBA-related duties and do not include root or root-level access. DBAs who require the ability to perform certain system administrator functions such as account creation or the editing of system configuration files use a separate system administrator role account that provides these capabilities, but do not receive full system administrator privileges. DBA's system administrator accounts with limited privileges must be monitored and audited in accordance with IRM 10.8.1. The implementing organization is required to coordinate this activity with the ACIO Cybersecurity. At a minimum, the DBA have the following responsibilities: Establish security for database objects within the database and for the DBMS according to IRS security policies; Support disaster/recovery planning, documentation and implementation efforts for the database(s); Establish database points of consistency; Coordinate with the SA to integrate database backups into the system related backup and recovery, including creating the backups if necessary; Periodically test backup copies of the databases; Recover the database to a current or previous state, if necessary; Recover individual objects (e.g., data rows) to a current or previous state; Identify database requirements of system resources; Provide network requirements for the database to the organizations responsible for designing and implementing network services; Manage the database configuration (e.g., architecture, internal settings) according to the SA&A operating system security configuration; Support Security Assessments and Authorization efforts; Monitor/manage database performance and capacity; Monitor user activities where appropriate; and Enable and configure audit logging on all IRS systems in accordance with IRM 10.8.1, and all other applicable configuration IRMs.

IRS Patch and Vulnerability Group (PVG)

10.8.2.3.2.5 (04-29-2025) IRS Patch and Vulnerability Group (PVG) An IRS PVG is created to facilitate the identification and distribution of patches within the IRS. The PVG is tasked to implement the patch and vulnerability management program throughout the IRS. The PVG is the central point for vulnerability remediation efforts, such as OS and application patching and configuration changes. [NIST: SP 800-40r2] The PVG has the following duties: [NIST: SP 800-40r2] System Inventories: Use existing inventories of the organization's IT resources to determine which hardware equipment, operating systems, and software applications are used within the organization. The PVG also maintains a manual inventory of IT resources not captured in the existing inventories. Monitor for Vulnerabilities, Remediations, and Threats: Monitor security sources for vulnerability announcements, patch and non-patch remediations, and emerging threats that correspond to the software within the PVG's system inventory. Prioritize Vulnerability Remediation: Prioritize the order in which the organization addresses vulnerability remediation; Create an Organization-Specific Remediation Database: Create a database of remediations that need to be applied organization-wide; Conduct Generic Testing of Remediations: Test patches and non-patch remediations on IT devices that use standardized configurations. This will avoid the need for local administrators to perform redundant testing. The PVG also works closely with local administrators to test patches and configuration changes on important systems. Deploy Vulnerability Remediations: Oversee vulnerability remediation; Distribute Vulnerability and Remediation Information to Local Administrators: Inform local administrators about vulnerabilities and remediations that correspond to software packages included within the PVG scope and that are in the organizational software inventory. Perform Automated Deployment of Patches: Deploy patches automatically to IT devices using enterprise patch management tools. Alternately, the PVG works closely with the group actually running the patch management tools. Note: Automated patching tools allow an administrator to update hundreds or even thousands of systems from a single console. Deployment is fairly simple when there are homogeneous computing platforms, with standardized desktop systems and similarly configured servers. Multi-platform environments, nonstandard desktop systems, legacy computers, and computers with unusual configurations may also be integrated. Configure Automatic Update of Applications Whenever Possible and Appropriate: Many newer applications provide a feature that checks the vendor's web site for updates. This feature can be very useful in minimizing the level of effort required to identify, distribute, and install patches. However, some organizations may not wish to implement this feature because it might interfere with their configuration management process. A recommended option would be a locally distributed automated update process, where the patches are made available from the organization's network. Applications can then be updated from the local network instead of from the Internet. Verify Vulnerability Remediation Through Network and Host Vulnerability Scanning: Verify that vulnerabilities have been successfully remediated. Vulnerability Remediation Training: Train administrators on how to apply vulnerability remediations. Note: Refer to IRM 10.8.50 for additional guidance. Note: NIST SP 800-40 currently has four versions. The original SP 800-40, Procedures for Handling Security Patches (2002), provided basic information on patching procedures and sources of patch and vulnerability information. SP 800-40 Version 2.0, Creating a Patch and Vulnerability Management Program (2005), built on the original by adding content on processes, metrics, and common issues. Although SP 800-40 and SP 800-40 Version 2.0 are primarily of interest from a historical perspective, they address many of the same topics that organizations are still struggling with today. The third version, SP 800-40, Revision 3, Guide to Enterprise Patch Management Technologies (2013), was written under the assumption that readers already understood the basics of patch management and that what they most needed help with was implementing, configuring, securing, and using enterprise patch management technologies. The latest SP 800-40 version is based on the assumption that, in the overall scope of enterprise patch management, organizations would benefit more from rethinking their patch management planning than their patch management technology.
