What is Host Based Security System (HBSS)?

Host Based Security System (HBSS) is a suite of security software applications used by the U.S. Department of Defense (DoD) to monitor, detect, and respond to cyber threats on individual computer systems (hosts). It provides capabilities such as intrusion detection, host-based firewalls, data loss prevention, and vulnerability scanning. HBSS is commonly used to enforce security policies, improve situational awareness, and protect sensitive data on DoD networks. It is often deployed and managed centrally to ensure consistent security across a large number of systems.
