What they're saying: "All organizations must recognize that no company is safe from being targeted by ransomware, regardless of size or location," White House deputy national security adviser Anne Neuberger wrote in the memo to businesses. "Much as our homes have locks and alarm systems and our office buildings have guards and security to meet the threat of theft, we urge you to take ransomware crime seriously and ensure your corporate cyber defenses match the threat," it continues. Neuberger recommended that businesses enable multi-factor authentication for sensitive accounts, use endpoint detection and response tools, and encrypt and regularly back up their data. She also called on businesses to separate corporate business functions and manufacturing/production operations to ensure certain networks can be isolated and continue to operate in the event of an attack.
