Improving Enterprise Patching for General IT Systems

• The report highlights the long-standing issue of cybersecurity attacks due to unpatched software. Despite widespread awareness of this vulnerability, many organizations struggle to update their software.
• NIST outlines several challenges in patch management, such as the difficulty of prioritizing and testing patches, the resource intensity of the process, and the potential impact on system and service availability.
• The guide offers solutions to these challenges by demonstrating how existing tools can be utilized more effectively for patching needs.

This NIST publication addresses the critical challenge of patch management in cybersecurity. Authored by experts from the National Cybersecurity Center of Excellence (NCCoE) at NIST and collaborators from various organizations, including Microsoft and The MITRE Corporation, the publication provides practical guidance for enhancing patching practices within IT systems.

The executive summary highlights the long-standing issue of cybersecurity attacks due to unpatched software. Despite widespread awareness of this vulnerability, many organizations struggle to update their software. The report emphasizes using a risk-based approach. A successful patching strategy must balance security with business objectives and mission impact. The NCCoE collaborated with cybersecurity technology providers to explore better approaches for enterprise patching, aiming to improve security hygiene and reduce the likelihood of data breaches.

The report outlines several challenges in patch management, such as the difficulty of prioritizing and testing patches, the resource intensity of the process, and the potential impact on system and service availability. Delaying patch deployment can increase the risk of attacks. The guide offers solutions to these challenges by demonstrating how existing tools can be utilized more effectively for patching needs, including routine and emergencies, and exploring alternative methods like isolation when not feasible.

The PDF is divided into several volumes, including an executive summary, detailed security risks and capabilities analyses, and practical how-to guides. It is intended for various professionals, from business decision-makers to IT professionals, providing comprehensive insights into improving patching practices. The guide also underscores the importance of patch management in the broader context of cybersecurity hygiene and the journey toward zero trust architecture.
