Blueprint for Ransomware Defense: An Action Plan for Ransomware Mitigation, Response, and Recovery for Small- and Medium-Sized Enterprises
Ransomware Task Force
In response to Action 3.1.1 of the Ransomware Task Force (RTF) report, which calls for the cybersecurity community to “develop a clear, actionable framework for ransomware mitigation, response, and recovery,” the Blueprint for Ransomware Defense Working Group developed a Blueprint comprised of a curated subset of essential cyber hygiene Safeguards from the Center for Internet Security Critical Security Controls® (CIS Controls®) v8. These Safeguards represent a minimum standard of information security for all enterprises and are what should be applied to defend against the most common attacks. This Blueprint for Ransomware Defense represents a set of Foundational and Actionable Safeguards, aimed at small- and medium-sized enterprises (SMEs).
Consequently, this Blueprint for Ransomware Defense utilizes the CIS Controls, a prioritized and prescriptive set of actions developed by a global community of cybersecurity experts. The forty (40) recommended Safeguards included in the Blueprint have been carefully selected not only for their ease-of-implementation but their effectiveness in defending against ransomware attacks. This has been backed by analysis from the CIS Community Defense Model v2.0 (CIS CDM v2.0), where implementing the Safeguards in this Blueprint defends against over 70% of the attack techniques associated with ransomware. It is important to note that this Blueprint is not intended to serve as an implementation guide, but rather a recommendation of defensive actions that can be taken to protect against and respond to ransomware and other common cyber attacks.download pdf
