Abstract
In one embodiment, an encryption system may protect user login metadata from hammering attacks. A data storage may store an integrity protected data set for an operating system in a storage location. A processor may register a counter reading from a remote counter in a secure location separate from the storage location. The processor may determine a lockout state of the integrity protected data set based on the counter reading.
