    Abstract: A method includes a data protection system determining, based on a first security threat detection process, that a storage system is possibly being targeted by a security threat; performing, based on the determining that the storage system is possibly being targeted by the security threat, a first remedial action with respect to the storage system, the first remedial action comprising generating a snapshot of data stored by the storage system; confirming, based on a second security threat detection process, whether the storage system is possibly being targeted by the security threat; and performing, based on the confirming whether the storage system is possibly being targeted by the security threat, a second remedial action with respect to the storage system, the second remedial action comprising specifying a retention duration with respect to the snapshot.

    Abstract: An illustrative method includes determining that a total amount of read traffic and write traffic processed by a storage system during a time period exceeds a threshold; determining a first compressibility metric associated with the write traffic; determining a second compressibility metric associated with the read traffic; 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 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; and modifying, in response to the determining that the storage system is possibly being targeted by the security threat, a data protection parameter set for one or more recovery datasets generated by the storage system.
