Patch management policy
Updated on 28 April 2020
Outlines the University’s approach to the patch management of its infrastructure assets
This policy outlines the University’s approach to the patch management of its infrastructure assets. It provides the guiding principles and responsibilities to ensure the University’s patch management objectives are met.
This policy is applicable across the University and applies to:
- all individuals who have access to University information and technologies
- all facilities, technology and services that are used to process University information
- all information processed, accessed, manipulated, or stored (in any format) by the University pursuant to its operational activities
- internal and external processes used to process University information
- external parties that provide information processing services to the University
The policy will be communicated to users and relevant external parties.
The University’s objectives for this policy are to:
- safeguard the University’s information from security threats that could have an adverse effect on its operations or reputation
- fulfil the University’s duty of care toward the information with which it has been entrusted
- protect the confidentiality, integrity, availability, and value of information through the optimal use of controls
- Patching of University-owned systems will be centrally managed.
- Assessment of the criticality of vulnerabilities will be carried out by the Security and Risk Management Officer in conjunction with Product Engineers in UoD IT
- University systems, devices, and applications must be updated within seven days of any release of a patch that fixes High vulnerabilities. Based on the assessed severity and potential/actual impact, the Assistant Director of IT for Security, Infrastructure, and Research Computing may mandate a shorter timeframe for any particular instance.
- Patches to Medium and Low vulnerabilities must be installed within fourteen (14) days of availability.
- Unpatched user and/or BYOD devices (laptops, smartphones, tablets etc.) may be blocked from accessing the University network or systems.
- Non-compliant systems may be quarantined or otherwise switched off.
- The University has no mandate to require that personally-owned devices are kept up-to-date. Unpatched personally-owned devices may, however, be blocked from accessing the University’s network if they pose an identifiable risk.
- Patching will normally occur during the published IT at-risk windows which are Tuesday each week 7am until 9am and Thursday 7am until 9am, Where the IT at-risk windows are insufficient, communication of alternate times and durations will be provided through official University channels. Patching will normally be carried out by the Data Centre Operations team members.
