A plan that outlines how a business can prepare against cybersecurity threats and respond to incidents can help limit the damages related to loss of data and operations. It can also improve the chances of avoiding many types of incidents, including ransomware. The following guidelines can help dealerships create a response framework that can be tailored to their specific organization and capacity for planning. KEY ELEMENTS OF A RANSOMWARE RESPONSE PLAN Ransomware response depends on a timely assessment of a live incident’s severity and impact, clearly defined roles and reactions and a thorough investigation to ensure the threat is neutralized and operations can be brought back to a secure state. To be effective, your strategy must be in place before an incident occurs. Here’s how to get started. BEFORE AN INCIDENT 1. Prepare • Educate key personnel regarding current cyber-risks and objectives of cybercriminals. • Appoint the most qualified individual to lead the creation, implementation and updating of the response plan. Alternatively, you can supervise a contract with a professional security vendor that creates the response plan. • Conduct a company risk assessment and be sure to include data inventory. • Create and maintain encrypted, offline or immutable backups of essential company and customer data. • Implement strong protections around identity and access management, such as multifactor authentication on all devices that can access company networks. • Formulate, test and continuously evolve the response plan. It should identify stakeholders and their roles, communication tactics and off-network channels, reporting procedures required by regulatory bodies or local law enforcement, and criteria for restoration of safe states. 2. Backup and Test • Regularly confirm the integrity of backups. • Do not look at backups as the “last line of defense.” No backup method is 100% cybersecure, and stealthy bad actors can corrupt backups even before they launch ransomware. DURING AN INCIDENT 3. Detection and Assessment • Use security tools to monitor network traffic for evidence of an adversary’s presence or movement and issue alerts. • Assess which systems are easily compromised by ransomware and isolate them. Coordinate a shutdown of all devices that cannot disconnect from the affected systems. • Reset all credentials and passwords connected to affected systems. 4. Communication and Reporting • Inform all internal teams and stakeholders on a preselected communication channel to ensure individuals essential to the response are engaged. • As needed, report the incident to affected third parties or vendors that assist your dealership with security and incident response. • Notify cybersecurity agencies and/or local law enforcement to maintain regulatory compliance and to receive additional assistance or guidance. • Communicate with third parties and clients to ensure they have not experienced financial impacts after the incident. 5. Containment and Remediation • Disable any system involved in the initial breach, as well as connected systems that malicious actors could use to access other parts of the company network or data systems. • Analyze network traffic and endpoints for evidence of the malicious actors’ persistence. Remediate vulnerabilities. • Rebuild the systems that are most critical to business operations. • Reset passwords and permissions. 8
