The invention relates to a system for protecting a computerized device from a malicious activity resulting from a malicious code, which comprises^ (a) a first DC supply monitoring unit which is located within a separate computerized environment, namely an environment which is totally separated and isolated both physically and in terms of connectivity from the hardware and software of the computerized environment of the device! (b) a memory database for storing one or more signatures of known malicious events, each of said signatures describes the temporal effect of a malicious event, respectively, on the power consumption from the DC supply of the device! and (c) a microprocessor within said DC supply monitoring unit for continuously monitoring the power consumption from said DC supply of the device, comparing temporal characteristics of the power consumption with said malicious events signatures in said database, and alerting upon detection of a match, wherein said DC supply monitoring unit is at most physically connected to the DC supply of the device. |
