Abstract
A method for securing a data storage device (DSD) against rogue behaviour by a host, the method executed by a controller of the DSD and comprising: determining a host type of the host; detecting one or more access activities performed by the host on the DSD; processing the one or more access activities to determine a security threat level of the host, wherein the security threat level is determined by weighting one or more corresponding access activity parameters by one or more impact weights; and in response to determining that the security threat level of the host is greater than or equal to a rogue host threat level, controlling the access activities performable by the host on the DSD to safeguard the DSD against the host, wherein the one or more impact weights are dynamically determined based on the host type.
