Abstract: An illustrative method includes a data protection system determining a first compressibility metric associated with write traffic processed by a storage system, the first compressibility metric indicating an amount of storage space saved if the write traffic is compressed; determining a second compressibility metric associated with read traffic processed by a storage system, the second compressibility metric indicating an amount of storage space saved if the read traffic is compressed; determining, based on a comparison of the first compressibility metric with the second compressibility metric, that the write traffic is less compressible than the read traffic; determining, based on the write traffic being less compressible than the read traffic, that the storage system is possibly being targeted by a security threat; and performing, based on the determining that the storage system is possibly being targeted by the security threat, a remedial action with respect to the storage system.

Abstract: An illustrative method includes a data protection system determining that a total amount of read traffic and write traffic processed by a storage system during a time period exceeds a threshold, the read traffic representing data read from the storage system during the time period and the write traffic representing data written to the storage system during the time period, determining that the write traffic is less compressible than the read traffic, and determining, based on the total amount of read traffic and write traffic exceeding the threshold and on the write traffic being less compressible than the read traffic, that the storage system is possibly being targeted by a security threat.
