Abstract: A processing device in one embodiment comprises a processor coupled to a memory and is configured to intercept a storage communication directed over a storage channel between a potentially infected machine and an associated storage system, and to determine if the intercepted storage communication is from a security agent deployed on the potentially infected machine. If the intercepted storage communication is from the security agent, at least a portion of the communication is provided to a security system. If the intercepted storage communication is not from the security agent, the communication is forwarded to the storage system. Accordingly, the security agent is configured to communicate with the security system using storage communications sent over the storage channel in a manner that avoids detection of the security agent by malware that may be installed on the machine and configured to monitor network communications.
