To establish policy for the proper use of District government provided electronic mail (email) services.
DC Official Code § 1-1401 et seq., provides the Office of the Chief Technology Officer (“OCTO”) with the authority to provide information technology (IT) services, write and enforce IT policies, and secure the network and IT systems for the District. This document can be found at: https://code.dccouncil.us/dc/council/code/sections/1-1402.html.
This policy applies to all District workforce members responsible for application identity and role definition on behalf of the District, and/or any District agency/District/entity who receive enterprise services from OCTO. In addition, this policy applies to any providers and third-party entities with access to District information, networks, and applications.
DC agencies must adopt the framework provided in this policy when responding to cybersecurity incidents to ensure that they safeguard the information systems and information technology contained on the internal District of Columbia Wide Area Network (DC Government system).
4.1. Identification of Incidents
4.1.1. All users of the DC Government system must refer cybersecurity-related suspicious activities or concerns ("security incident") to OCTO for security incident handling.
4.1.2. After the security incident is reported to OCTO, or after it is discovered by OCTO's internal monitoring, OCTO will take the following actions:
22.214.171.124. Log and the track reported incidents; and
126.96.36.199. Take steps to investigate, escalate, remediation, refer, otherwise address the incident.
4.1.3. Agency Chief lnformation Officers (CIO) and/or Agency Information Security Officers (ISO) must participate in all CSIRT security incident-related communications regarding his or her DC Agency until CSIRT remediates or stabilizes the security incident.
4.2. Cyber Security Incident Response Team (CSIRT) and Coordinator
4.2.1. CSIRT Coordinator: OCTO will have a dedicated CSIRT coordinator that is responsible for all communication regarding security incidents. The CSTRT coordinator is responsible for resolving and reporting security incidents and assembling a CSTRT team. The Chief Technology Officer or his or her designee must designate an OCTO employee to serve as the CSIRT coordinator.
4.2.2. CSIRT Team: The CSIRT coordinator must identify and recruit DC Agency CIOs, DC Agency ISOs, and associated stakeholders to form the CSIRT. The membership of the CSIRT depends upon the severity level of an incident.
4.3. Security Incident Classification Matrix
OCTO must establish a Security Incident Assessment Classification Matrix ("Matrix") to guide CSIRT's response to each security incident. The Matrix must establish a class of security incidents and specific procedures for responding to each class of security incident. The description of each class of security incidents must also identify the OCTO personnel and DC Agency personnel that must be contacted and engaged to resolve the security incident. The Matrix must establish escalation procedures that identify contact persons within OCTO and, if applicable DC Agencies, to respond to each level of escalation.
4.4. Documentation and Communication of Incidents
OCTO will ensure that incidents are appropriately logged and archived. The CSIRT Coordinator will be responsible for communicating the incident to appropriate personnel and provide updates and instruction for the duration of the incident.
4.5. Subordinate Procedures
The OCTO Chief Information Security Officer (CISO) or IT Security Director must maintain standard procedures to respond to and investigate each security incident. He or she must also secure the custody of any evidence obtained during the investigation. The Incident classification matrix will govern the application of these procedures.
Exceptions to this policy shall be requested in writing to the Agency’s CIO and the request will be escalated to the OCTO Chief Information Security Officer (“CISO”) for approval.
