Technical Glossary

SEC001 Physical and Cyber Security Convergence
The integration of physical security systems including access control, video surveillance, and intrusion detection with cybersecurity infrastructure to create unified defense platforms that address threats spanning both physical and digital domains. Convergence enables correlated analysis where a physical badge swipe triggers verification against network login activity, and a cybersecurity incident prompts physical access restrictions to sensitive areas. AI analytics platforms process data streams from both domains to identify multi-vector attacks that exploit gaps between traditionally siloed security functions. NIST and CISA promote converged security approaches as essential for protecting critical infrastructure facilities.

SEC002 Access Control Systems Architecture
The design and implementation of integrated systems that regulate entry to physical spaces and digital resources through credential verification, authentication, and authorization mechanisms deployed across an organization's facilities and information systems. Modern access control architectures combine smart card readers, biometric scanners, mobile credentials, and network authentication servers into unified platforms managed through centralized policy engines. AI enhances access control by enabling continuous authentication, adaptive risk-based access decisions, and anomaly detection across physical and logical access events. NIST SP 800-116 provides guidelines for the use of PIV credentials in physical access control systems.

SEC004 Intrusion Detection and Prevention
Integrated security systems that combine sensors, controllers, and analytics platforms to detect unauthorized physical entry and network intrusion attempts while automatically triggering prevention and response actions. Physical intrusion detection employs motion sensors, door contacts, glass break detectors, and vibration sensors while network IDS/IPS analyzes packet flows and system logs for malicious patterns. AI-enhanced systems correlate alerts from both physical and cyber sensors to reduce false positives and identify coordinated multi-vector intrusion attempts. NIST SP 800-94 provides the guide for intrusion detection and prevention system selection, deployment, and management.

SEC005 Security System Integration Platform
A middleware architecture that enables interoperability and data exchange between diverse security subsystems including access control, video management, alarm monitoring, and cybersecurity tools through standardized APIs and protocols. Integration platforms normalize data formats, synchronize events, and orchestrate automated responses across traditionally siloed security technologies to create unified situational awareness. Open standards such as ONVIF for video systems and OSDP for access control facilitate vendor-neutral integration and prevent technology lock-in. These platforms serve as the operational backbone for converged security operations centers managing both physical and cyber security domains.

SEC006 Industrial Control System Security
The protection of supervisory control and data acquisition systems, distributed control systems, and programmable logic controllers that manage physical processes in critical infrastructure sectors including energy, water, manufacturing, and transportation. ICS security addresses unique challenges including legacy system vulnerabilities, real-time operational requirements, safety constraints, and the convergence of operational technology with information technology networks. AI-powered monitoring solutions detect anomalous control commands, unauthorized configuration changes, and network intrusions specific to industrial protocol communications. NIST SP 800-82 provides the comprehensive guide to operational technology security for industrial control system environments.

SEC007 Security System Lifecycle Management
The structured management of security infrastructure from initial requirements analysis and design through procurement, installation, commissioning, operation, maintenance, and eventual decommissioning. Lifecycle management ensures that security systems remain effective through regular technology refreshes, software updates, performance testing, and alignment with evolving threat landscapes and compliance requirements. AI-driven asset management tools track system health, predict component failures, and optimize maintenance schedules to maximize security system availability and performance. ISO 55001 and NIST frameworks provide guidance on asset lifecycle management practices applicable to security infrastructure.

SEC008 Alarm Management and Response
The systematic process of receiving, prioritizing, validating, and dispatching responses to security alarms generated by physical sensors, access control violations, and cybersecurity monitoring systems. Effective alarm management reduces operator fatigue and missed critical events through intelligent alarm filtering, correlation, and suppression of nuisance alerts based on contextual analysis. AI-powered alarm systems learn normal operational patterns to dynamically adjust alarm thresholds, predict alarm cascades, and recommend optimal response actions based on historical incident data. ISA-18.2 and IEC 62682 provide industry standards for alarm management practices in security and industrial environments.

SEC009 Perimeter Security Technology
Advanced detection and deterrence systems deployed along facility boundaries that combine physical barriers with electronic sensors, AI-powered video analytics, and automated response mechanisms to prevent unauthorized access to protected sites. Modern perimeter systems integrate radar, lidar, thermal imaging, and fiber-optic sensing with intelligent video analytics that distinguish between genuine threats and environmental false alarms.
