B. Required Actions
This policy identifies the required actions when it is determined that an IS incident has likely occurred. Specific procedures are outlined in the UW System IR Plan. The UW System IR Plan will be exercised for any multi-institution IS incident and/or when UW System leads an enterprise-wide IS incident response.
- UW System employees who suspect that an incident has likely occurred, must report it to their organization’s Information Security lead and Chief Information Officer. Individuals involved in IS incidents must cooperate with investigation teams and provide access to all impacted UW System assets. Depending on the severity and breadth of the incident, investigation teams may be comprised of local IT personnel, UW System Administrative and/or UW Shared Services entities and/or local law enforcement. In situations involving personally owned device may be necessary to ensure university owned data have not been compromised.
- Verbal or written initial notification to the UW System AVP for Information Security is required within one (1) business day of discovery, if a confirmed incident meets reportable criteria outlined above. If the UW System AVP for Information Security is not available, notification must be made to the UW System Director of Information Security/Chief Information Security Officer (CISO). Required reporting elements, to the extend known, include:
- date of incident;

- type of incident (examples include but are not limited to fraud, data breach/exposure, theft, malware, phishing, etc);
- estimated number of individuals impacted and/or records exposed/breached; and

Notification must include above reporting elements in addition to designation of an incident commander, periodicity of planned communication to UW System Administration, updated incident information, and next steps including any anticipated request for assistance.
- The Traffic Light Protocol (TLP) must be used for all written correspondence. See the link here for TLP details.
- Threat intelligence must be shared with other UW institutions as prescribed in the UW System IS IR Plan.
- Once the closure criteria outlined in the UW System IS IR Plan are met, institutions must communicate the closure date to the UW System Office of Information Security.
- Once an incident is closed, institutions must submit a Final Findings Report as prescribed in the UW System IS IR Plan.
- The UW System Office of Information Security must maintain a record of all confirmed IS incidents and their resolutions.
- Each Chancellor, or designee, and the UW System Vice President for Administration or central administration designee must review their organization’s IS incident events on a quarterly basis.
