Prevent Ransomware with Ransomware Self-Assessment Tools

Ransomware is a type of malicious software that encrypts data, demanding a ransom, often paid in cryptocurrency, to attackers in exchange for a decryption key to regain access.?The issue with ransomware is that even if companies decide to pay malicious actors, there is no guarantee they will receive a decryption key. For example, in the two largest ransomware attacks in history, WannaCry and NotPetya, it was rare and unlikely that victims would actually receive a working decryption key. That’s what makes ransomware so disruptive, putting both users and security specialists in a dead-end.

A Ransomware Self-Assessment Tool (R-SAT) is a structured questionnaire designed to help organizations, particularly financial institutions, evaluate their preparedness against ransomware attacks. By systematically reviewing security measures, policies, and response strategies, organizations can identify vulnerabilities and areas for improvement, strengthening their defenses against ransomware threats."

Tools like the CISA Ransomware Readiness Assessment, NIST Cybersecurity Framework, and FFIEC Cybersecurity Assessment Tool are related to ransomware preparedness and will definitely help with security posture against ransomware, but they aren't as directly focused on ransomware as the CSBS R-SAT is.

CSBS covers a wide range of cybersecurity topics like risk management, critical infrastructure protection, event detection, incident response, and recovery strategies. It addresses key areas such as identifying vulnerabilities, protecting resources, detecting threats, ensuring recovery capabilities, and verifying the proper configuration of cybersecurity tools and solutions.

To have a better idea of how CSBS R-SAT looks and works, let’s break down a few questions from it.

So, the first question is assessing the security posture of the company by asking whether the institution has implemented cybersecurity controls to prevent cyber-attacks, and if so, which standards or frameworks. The second question is assessing whether the institution has conducted a gap analysis to identify any cybersecurity controls that have not been implemented but are recommended by the standards and frameworks the institution follows.

The questionnaire has vendor and third-party related questions, questions about preparing for different attack vectors, employee security awareness training, backup, preventative controls, and more.

Ransomware Self-Assessment Tools are not mandatory for compliance with the Gramm-Leach-Bliley Act, NIST RMF, PCI DSS, or other frameworks, but they can be used as part of a broader cybersecurity preparedness strategy, providing valuable insights into an organization’s resilience against ransomware attacks.
