Statement of Policy
Washington University in St. Louis (WashU) is committed to conducting all university activities in compliance with all applicable laws, regulations and university policies. WashU has adopted this policy to outline the security measures required to protect electronic information systems and related equipment from unauthorized use.
This policy and associated guidance covers a well-defined and organized approach for vulnerability management to reduce infrastructure risks and integrate with patch management. To ensure confidentiality, integrity, and availability of WashU systems Information Security Office (ISO) and Information Technology (IT) will develop a documented vulnerability management process for the efficient and effective assessment and mitigation of IT infrastructure risks.
This policy is applicable to all WashU IT infrastructures – shared and distributed.
The audience for this policy is all WashU faculty, staff, and students. It also applies for all other agents of the university with access to WashU information and network for contracted services. This includes, but not limited to partners, affiliates, contractors, temporary employees, trainees, guests, and volunteers. The titles will be referred collectively hereafter as “WashU community”.
The Information Security Office (ISO) will document, implement, and maintain a vulnerability management process for WashU. The process will be integrated into the IT flaw remediation (patch) process managed by IT.
Appropriate vulnerability assessment tools and techniques will be implemented. Selected personnel will be trained in their use and maintenance. The ISO will periodically test the security posture by scanning the information systems owned and managed by WashU with vulnerability tools. The frequency of the scans will be scheduled based upon the level of risk and data classification.
The ISO will analyze the scans and their reports for vulnerability impact for WashU. The ISO will deliver a formal report that will identify the vulnerabilities requiring remediation or mitigation based on risk, patch requirements, and classification documented in the Vulnerability Management Operational Process. Departments and schools will remediate or mitigate the vulnerability within 90 days. The ISO will assist with remediation or mitigation planning as needed.
The information obtained from the vulnerability scanning process will be shared with appropriate personnel throughout the organization on a “need to know” basis to help eliminate similar vulnerabilities in other information systems.
Systems that are not remediated or granted an exception within the 90 days will be escalated to the area business director and recommended that the vulnerable device be removed from the network until such a time that the device can be brought into compliance.
The ISO will measure the compliance to this policy through various methods, including but not limited to, reports, internal and external audits, and feedback to the policy owner. Exceptions to the policy must be approved by the ISO in advance. Non-compliance will be addressed with management, Area Specific Compliance Office, Human Resources, or the Office of Student Conduct.
