Cyber hygiene describes recommended mitigations for the small number of root causes responsible for many cybersecurity incidents. Implementing a few simple practices can address these common root causes. Patching is a particularly important component of cyber hygiene, but existing tools and processes are frequently insufficient to rapidly mitigate this risk in many environments and situations. The objective of this project is to demonstrate a proposed approach for improving enterprise patching practices for general IT systems. Commercial and open source tools will be used to aid with the most challenging aspects of patching, including system characterization and prioritization, patch testing, and patch implementation tracking and verification. These tools will be accompanied by actionable, prescriptive guidance on establishing policies and processes for the entire patching life cycle, in the form of a freely available NIST Cybersecurity Practice Guide.
