The National Institute of Standards and Technology (NIST) has released two new guides to help address data integrity challenges poses by ransomware attacks and other “destructive” events, which include destructive malware. Organizations can use the first guide, SP 1800-25, to develop a strategy for identifying and protecting assets against one of these events. They can use the second, SP 1800-26, to develop a strategy for detecting and responding to events that occur, while ensuring the integrity and availability of data critical to supporting operations. These two new publications complement SP 1800-11, which was published in September 2020 and addresses recovering from ransomware and other destructive events.
