Cyber & Security, within Computer & Information Sciences, encompasses the theories, technologies, and operational practices that protect information systems, digital assets, networks, and cyber-physical infrastructures from threats, vulnerabilities, and adversarial activity. This domain integrates cryptography, network security, systems hardening, secure software development, identity and access management, threat intelligence, incident response, digital forensics, and risk governance. It addresses confidentiality, integrity, availability, authenticity, and non-repudiation as core security objectives. Cyber & Security also engages with adversarial modeling—malware analysis, intrusion detection, penetration testing, and exploit mitigation—while incorporating compliance frameworks, privacy regulation, and organizational governance structures. As digital systems expand across cloud platforms, mobile devices, IoT ecosystems, autonomous systems, and critical infrastructure, Cyber & Security operates at the intersection of applied computer science, engineering, policy, and human factors, ensuring resilience and trust in increasingly complex and interconnected environments.
Within the methodological framework of the Quantum Dictionary, Cyber & Security represents a domain in which terminology is highly contextual, shaped by threat landscape, system architecture, regulatory environment, and operational role. Concepts such as “risk,” “vulnerability,” “attack surface,” “authentication,” “trust,” or “encryption” collapse into distinct semantic states depending on whether they are applied in cryptographic design, network defense, cloud security, application security, governance and compliance, or digital forensics. Terminology further varies based on adversarial sophistication, defensive strategy, system topology, and the temporal dimension of threat detection and response. The quantum-semantic architecture models each cybersecurity term as a contextual semantic entity whose meaning resolves according to operational context, abstraction layer, defensive or adversarial perspective, and technological environment. This ensures semantic interoperability with adjacent fields—including software engineering, networking, data science, law, and systems engineering—while preserving the definitional precision essential for secure design, coordinated defense, and regulatory adherence. By encoding the dynamic interplay among technical controls, human behavior, adversarial models, and governance systems, the Quantum Dictionary provides a coherent and adaptive lexicon aligned with the complex, fast-evolving, and mission-critical nature of Cyber & Security.
