Host-Based Security System (HBSS) is a commercial, off-the-shelf (COTS) endpoint security software that the Department of Defense uses to monitor, detect, and defend IT assets and systems . Recently, the Defense Information Systems Agency (DISA) has rebranded HBSS into a new suite called Endpoint Security Solutions (ESS), which adds new capabilities on top of the existing HBSS software . ESS is a multi-point product designed to meet known intrusion points, discover gaps, and reduce the likelihood of unauthorized device and network access .
The latest development in this sector is the release of HIPS 8.0 Migration Tool Supplemental Training Aide by DISA HBS Program Management office in support of USCYBERCOM TASKORD 12-0789 “Upgrading to Host Based Security System (HBSS) ePO 4.5 MR 4” .
Features of Host Based Security System (HBSS)
Host-Based Security System (HBSS) is a commercial, off-the-shelf (COTS) endpoint security software that the Department of Defense uses to monitor, detect, and defend IT assets and systems . It provides host-level protection for several threat vectors that typically target desktop operating systems . HBSS is based on McAfee, Inc’s ePolicy Orchestrator (ePO) and other McAfee point product security applications such as Host Intrusion Prevention System (HIPS) . The system comprises several modules, including:
- Host Intrusion Prevention System (HIPS): A module that provides intrusion detection and prevention capabilities to protect against known and unknown threats .
- Policy Auditor (PA): A module that enables administrators to audit and enforce compliance with security policies across the enterprise .
- Assets Baseline Module (ABM): A module that enables administrators to establish a baseline of authorized software and configuration settings for each host ¹.
- Rogue System Detection (RSD): A module that detects unauthorized devices on the network and prevents them from accessing sensitive data .
- Device Control Module (DCM): A module that enables administrators to control access to peripheral devices such as USB drives, CD/DVD drives, and printers .
- Asset Publishing Service (APS): A module that enables administrators to publish asset information to other HBSS servers in the enterprise .

Difference between HIPS and PA modules in HBSS
Host Intrusion Prevention System (HIPS) and Policy Auditor (PA) are two of the several modules that comprise the Host-Based Security System (HBSS) .
HIPS is a module that provides intrusion detection and prevention capabilities to protect against known and unknown threats . It is designed to monitor system activity and detect suspicious behavior, such as unauthorized access attempts, malware infections, and other security breaches . HIPS can also block or quarantine malicious activity in real-time, preventing it from causing further damage to the system .
PA, on the other hand, is a module that enables administrators to audit and enforce compliance with security policies across the enterprise . It provides a centralized view of the security posture of all endpoints in the network, allowing administrators to identify vulnerabilities and take corrective action as needed . PA can also generate reports that demonstrate compliance with regulatory requirements such as HIPAA, PCI-DSS, and SOX .

HBSS protects against threats by providing a multi-layered defense mechanism that includes both signature-based and behavior-based detection techniques . The HIPS module uses signature-based detection to identify known threats such as viruses, malware, and spyware .
It also uses behavior-based detection to identify unknown threats by monitoring system activity for suspicious behavior patterns . The PA module ensures compliance with security policies by auditing endpoints for vulnerabilities and enforcing corrective action as needed .
The ABM module helps prevent unauthorized changes to system configurations by establishing a baseline of authorized software and configuration settings for each host . The RSD module detects unauthorized devices on the network and prevents them from accessing sensitive data .
The DCM module controls access to peripheral devices such as USB drives, CD/DVD drives, and printers, thereby reducing the risk of data loss or theft . Finally, the APS module enables administrators to publish asset information to other HBSS servers in the enterprise, ensuring that all endpoints are protected against known threats .
FAQ
10 FAQ and relevant answers on host-based security systems
1. What is a host-based security system?
A host-based security system is a set of security controls that are implemented on individual computer systems, such as servers, workstations, and laptops. Host-based security systems protect these systems from unauthorized access, use, disclosure, disruption, modification, or destruction.
2. What are the benefits of using a host-based security system?
Host-based security systems offer a number of benefits, including:
- Protection against a wide range of threats: Host-based security systems can protect against a wide range of threats, including viruses, malware, spyware, ransomware, and denial-of-service attacks.
- Defense in depth: Host-based security systems provide an additional layer of security beyond network-based security systems. This helps to protect systems even if a network-based security system is compromised.
- Flexibility: Host-based security systems can be tailored to the specific needs of each system. This makes them a good choice for both small and large organizations.
3. What are the different types of host-based security systems?
There are a variety of different types of host-based security systems, including:
