Ransomware detection on block storage

See this idea on ideas.ibm.com

“How IBM FlashSystem can recognize the possible cyber ransomware attack?”



The ransomware do data encryption. Most of our Clients uses data that are eligible for compression and the average ratio is around 2:1. The idea is to measure compression ratio trends on vdisk level (built in comprestimator "analyzevdiskbysystem") to recognize rapid changes and alert about those vdisks with lower "day to day" compression as candidates of an possible attack. Why vdisk level? To achieve the alert faster, global measurement on DRP or FCM level could be to slow and do not show possible affected hosts. On top of this not all systems uses compression on all vdisks.
 The "analyzevdiskbysystem" process do not impact array performance at all and what is simply needed is to perform the analyzes, download results to e.g. Spectrum Control and show trends. The best solution is to have build in function in GUI in FlashSystem.
