Most encryption ransomware can encrypt only the data that the user who activated the payload has permissions to access. Therefore, limiting each user's access rights to that user's role in keeping with the least privilege principle is a solid strategy for narrowing ransomware's ability to cripple your files.

With ransomware attacks growing in both number and sophistication, organizations need a solid, multi-layer defense strategy that helps them block attacks and quickly discover any infections in progress, so they can limit the impact on data and operations. A solid file backup and recovery process is of top importance among these measures.
