Extranet
Extranet: A private network that uses internet technology and the public telecommunication system to securely share part of a business’s information or operations with suppliers, vendors, partners, customers, or other businesses. It can be viewed as part of a company’s intranet that is extended to users outside the company, offering controlled access while maintaining privacy […]
Extreme Programming (XP)
Extreme Programming (XP): A software development methodology that is intended to improve software quality and responsiveness to changing customer requirements. As a type of agile software development, XP advocates frequent “releases” in short development cycles, which are intended to improve productivity and introduce checkpoints where new customer requirements can be adopted. Key practices include pair […]
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 […]
Fall-through Logic
Fall-through Logic: In programming, fall-through logic occurs in switch-case statements where the absence of a break statement causes the execution to continue from one case into the subsequent case. It’s intentional in certain programming scenarios but should be used cautiously to prevent logic errors. In security, careful design is required to avoid unintended actions from […]
False Acceptance Rate (FAR)
False Acceptance Rate (FAR): A measure used in biometric security systems to indicate the probability that the system will incorrectly accept an unauthorized user. It is one of the key metrics, along with the False Rejection Rate (FRR), used to assess the performance of a biometric system. A low FAR is desired as it reflects […]
