Fault Tolerance
Fault Tolerance: The ability of a system to continue functioning properly in the event of a hardware or software failure. This is achieved through the incorporation of redundancy in the system’s components or through techniques like replication of tasks so that in the event of a component failure, the system’s operation continues without disruption.
Fault tree analysis
Fault tree analysis: A method used to systematically analyze the causes of a failure or undesirable event in a system. Using a tree-like diagram, it represents the relationships between the system’s components, highlighting potential problems or threats that could lead to a failure.
Fence
Fence: In a physical security context, a fence is a barrier used to enclose or secure an area, typically made from posts connected by boards, wire, or rails, and is designed to prevent intrusion or escape. In computing, fencing can refer to a network security measure that isolates a node or system to protect the […]
Fail secure
Fail secure: A security term describing a feature or state where, upon failure, a system remains secure. In a fail-secure setup, if a component or system fails, it defaults to a locked or protected state rather than an open or unsecured one. This concept is commonly applied to access control systems, such as locked doors […]
Fail-open
Fail-open: A fail-open design refers to a security system’s configuration that, in the event of a system failure, defaults to an “open” state, allowing all traffic or access. This approach prioritizes availability and continuity of operations over strict access control, often used in scenarios where service disruption is unacceptable despite the potential security risks it […]
Fail-Over (Fail-over)
Fail-Over (Fail-over): A backup operational mode in which the functions of a system component (such as a processor, server, network, or database) are assumed by secondary system components when the primary component becomes unavailable through either failure or scheduled downtime. Fail-over helps maintain high availability and reliability by ensuring that services continue to operate in […]
