Ransomware Preparedness Assessment

Proactive Preparation Is the Best Protection Against Ransomware

While completely preventing ransomware attacks is nearly impossible, security and risk management professionals can take proactive steps to neutralize or mitigate their harm. Basic cyber hygiene remains fundamental. First, that means taking the time to accurately and regularly document the entire configuration of your network.  

 

When a local government was victimized by ransomware, it impacted the municipality’s police and fire dispatch systems, online utility payment system, centralized accounting system and many other critical segments on its network. Unfortunately, the IT director was unaware of how many servers were on the network. This lack of awareness delayed the initial remediation, especially when combined with limited viable backups for restoration.

Second, data mapping inventories are more important than ever. Starting last year, many ransomware actors threatened to release stolen data to pressure victims into paying ransoms. Almost overnight, ransomware attacks morphed from mainly expensive operational disruptions to crises fraught with regulatory data privacy and breach notification issues. Knowing what kind of data you have and everywhere it is collected, used and stored is imperative.

In Kroll’s experience, six fundamental security steps can deliver immediate layers of protection from ransomware:

• Institute least privilege policies for data/system access
• Delete unused email addresses
• Enforce strong password policies
• Implement multifactor authentication
• Create, update, segregate and protect viable backups
• Whitelist safe applications
• Accurately map network configurations

In the event that ransomware strikes, organizations should have a plan to take immediate action with six response steps that include:

• Isolate impacted systems from other computers and servers within the network and disconnect from both wired and wireless networks.
• Identify the infection, which sometimes is stated in the ransom note, but can also be determined from numerous open-source sites. Kroll can also help pinpoint not only the ransomware type, but any other malware and persistence mechanisms still present in your environment. 
• Report the incident to the appropriate local law enforcement agency – e.g., in the U.S., that’d be your local FBI field office or through the FBI Internet Crime Complaint Center, the police or the national Action Fraud website for the UK, or via the ReportCyber website for Australia.
• Think before you pay, which involves decision-making processes that should already be outlined in your incident response plan. If applicable, contact your cyber insurance carrier for any ransomware-related coverage. 
• Retain log data! Because many log types roll off quickly, timely action is necessary to retain any potentially relevant event data for subsequent investigation.
• Restore systems and ensure your organization has prioritized effective backup policies and protocols.

14 Key Security Areas of a Ransomware Protection Assessment

Kroll’s ransomware preparedness assessment aims to identify where your defenses are strong and where vulnerabilities exist that ransomware actors can exploit. Our methodology focuses on the cyber kill chain, a comprehensive examination that includes remote access configuration, phishing prevention, email and web protections, access controls and endpoint monitoring and end user awareness. At the end of our assessment, we will provide you with a prioritized, customized set of recommendations to help your organization deflect, detect or respond to a ransomware attack.

Kroll cyber experts will first focus on controls, processes and technology solutions to reduce the likelihood of ransomware-based attacks. During this step, we will:

• Analyze relevant firewall and network device configurations for security weaknesses 
• Review user activity logging and audit configurations to aid potential investigative efforts
• Review network and endpoint security monitoring solutions and processes
• Evaluate email and web filtering options and configurations to prevent phishing attacks and malicious payload delivery
• Review access and privileged access controls and processes
• Evaluate vulnerability and patch management controls and processes 

Kroll will conduct up to four remote interviews with technical teams to assess the secondary defensive measures in place to protect the organization against email-based attacks. This review will encompass:

• Remote access controls
• Email and web controls
• Application whitelisting and audit controls
• Endpoint protection controls
• Employee awareness and training
• Backup and audit logging controls
• Incident response
• Business processes related to vendor management
