The Host Based Security System (HBSS) is the official name given to the Department of Defense (DOD) commercial-off-the-shelf (COTS) suite of software applications used within the DOD to monitor, detect and counter attacks against the DOD computer networks and systems. The Enterprise-wide Information Assurance and computer Network Defense Solutions Steering Group (ESSG) sponsored the acquisition of the HBSS System for use within the DOD Enterprise Network. HBSS is deployed on both the Non-Classified Internet Protocol Routed Network (NIPRNet) and Secret Internet Protocol Routed Network (SIPRNet) networks, with priority given to installing it on the NIPRNet. HBSS is based on McAfee, Inc`s ePolicy Orchestrator (ePO) and other McAfee point product security applications such as Host Intrusion Prevention System (HIPS).
