Earlier this month, a White House memo was published to “Corporate Executives and Business Leaders” with recommended best practices to help mitigate the risk of ransomware. According to the memo, “(the U.S. Government) selected a small number of highly imactful steps to help you focus and make rapid progress on driving down risk.”

BlueOrange certainly agrees with the below list. Infact, if you have worked with us on a recent Security Risk Assessment these items will look familiar!

 

What (the U.S. Government) Urges You To Do Now:

  • Implement the five best practices from the President’s Executive Order: President Biden’s Improving the Nation’s Cybersecurity Executive Order is being implemented with speed and urgency across the Federal Government. We’re leading by example because these five best practices are high impact:
    • multifactor authentication (because passwords alone are routinely compromised),
    • endpoint detection & response (to hunt for malicious activity on a network and block it),
    • encryption (so if data is stolen, it is unusable)
    • and a skilled, empowered security team (to patch rapidly, and share and incorporate threat information in your defenses). These practices will significantly reduce the risk of a successful cyberattack.
  • Backup your data, system images, and configurations, regularly test them, and keep the backups offline: Ensure that backups are regularly tested and that they are not connected to the business network, as many ransomware variants try to find and encrypt or delete accessible backups. Maintaining current backups offline is critical because if your network data is encrypted with ransomware, your organization can restore systems.
  • Update and patch systems promptly: This includes maintaining the security of operating systems, applications, and firmware, in a timely manner. Consider using a centralized patch management system; use a risk-based assessment strategy to drive your patch management program.
  • Test your incident response plan: There’s nothing that shows the gaps in plans more than testing them. Run through some core questions and use those to build an incident response plan: Are you able to sustain business operations without access to certain systems? For how long? Would you turn off your manufacturing operations if business systems such as billing were offline?
  • Check Your Security Team’s Work: Use a 3rd party pen tester to test the security of your systems and your ability to defend against a sophisticated attack. Many ransomware criminals are aggressive and sophisticated and will find the equivalent of unlocked doors.
  • Segment your networks: There’s been a recent shift in ransomware attacks – from stealing data to disrupting operations. It’s critically important that your corporate business functions and manufacturing/production operations are separated and that you carefully filter and limit internet access to operational networks, identify links between these networks and develop workarounds or manual controls to ensure ICS networks can be isolated and continue operating if your corporate network is compromised. Regularly test contingency plans such as manual controls so that safety critical functions can be maintained during a cyber incident.”
