Védfunkció

Védfunkció is a Hungarian term used to describe a function or mechanism that provides defense against threats within a system. It is not a single formal mathematical concept, but a descriptive label used across disciplines such as biology, information technology, and engineering to denote protective action or responses. The term combines véde- (defense) and funkció (function), and its precise meaning depends on the field and context.

In biology and medicine, védfunkció refers to the immune defense or protective capabilities of an organism. This includes physical barriers like skin and mucous membranes, cellular responses such as phagocytosis and cytotoxic activity, and humoral responses including antibodies and the complement system. In physiology and immunology, the védfunkció is often discussed in terms of effectiveness, capacity, and regulatory mechanisms that maintain homeostasis against pathogens or injuries.

In cybersecurity and information systems, védfunkció describes the protective capabilities of a system against threats such as malware, intrusion, or data leakage. Components contributing to the védfunkció include firewalls, authentication and access controls, encryption, intrusion detection systems, and incident response procedures. The concept emphasizes the function or role of safeguards rather than any single technology.

In engineering and safety disciplines, védfunkció denotes safety or defense-related functions designed to prevent harm or limit consequences. Examples include emergency shutdowns, fail-safe designs, protective interlocks, and redundancy strategies. These functions are typically designed to meet reliability and safety criteria and may be verified through testing and certification.
