F5-402 key terms

An F5 toolchain role for relevant initial system-level configuration under supported versions, distinct from AS3 application-service configuration on a prepared system.

A schema-governed representation of intended application-service configuration whose acceptance still requires operation completion and actual service verification.

A processing workflow in which initial acceptance and final outcome occur at different times, requiring supported status, retry and concurrency handling.

A BIG-IP backend address and service combination eligible under its actual pool and health configuration, distinct from the node address alone.

Terminating one encrypted connection and establishing a separate encrypted connection under the selected model, with independently relevant certificate and trust requirements.

A BIG-IP DNS object associating a name and record type with configured DNS selection behavior, whose answer does not itself proxy the later application session.

An APM policy evaluated for subsequent supported web requests in the configured model, distinct from initial session establishment and identity collection.

The Traffic Management Microkernel associated with BIG-IP traffic processing in the classic architecture, distinct from configuration and administrative management responsibilities.

Propagation of eligible device-group configuration under supported rules, which does not universally include every runtime connection or external application dependency.

A package of system observations for an approved support investigation that can contain sensitive operational information and needs controlled handling.

A traffic-processing arrangement with distinct client-side and server-side connection contexts, whose reuse and protocol behavior depend on the actual configuration.

The configured value used to associate later traffic with a destination, distinct from the application’s own stored user-session state.

A controlled health check that tests relevant application behavior using defined requests and expected results, rather than only establishing a transport connection.

The principle that users and systems should be granted only the minimum access rights necessary to perform their tasks, reducing the potential damage from accidents or malicious activity.

A control that divides critical tasks among different individuals so that no single person can complete a sensitive action alone, helping to prevent fraud and errors.

An access control model where permissions are assigned to roles rather than individual users, and users are assigned to roles based on their job responsibilities.

An authentication method that requires two or more independent credentials from different categories (something you know, have, or are) to verify a user's identity.

The process of verifying the identity of a user, device, or system, typically through credentials such as passwords, tokens, or biometrics.

The process of determining what actions or resources an authenticated entity is permitted to access, often enforced through access control policies.

A mechanism that allows a user to log in once and access multiple applications or systems without re-entering credentials, improving usability and centralizing access control.

The process of converting plaintext into ciphertext using an algorithm and a key, so that only authorized parties can read the original information.

An encryption method that uses the same secret key for both encryption and decryption, offering speed but requiring secure key distribution.

Encryption using a suitable public-key scheme and a corresponding private key for decryption. Authenticated key distribution and the specified padding/protocol remain essential; signatures and key agreement are distinct constructions.

A digest construction mapping input to an output under its defined algorithm, with cryptographic versions designed for appropriate resistance properties. Password storage needs a suitable salted password-hashing/KDF scheme rather than a bare fast digest.

An electronic signature that uses asymmetric cryptography to verify the authenticity and integrity of a message or document.

The policies and mechanisms that determine who can access which systems, data, or facilities and under what conditions.

A network security device or software that monitors and controls incoming and outgoing traffic based on predetermined security rules, acting as a barrier between trusted and untrusted networks.

A system that monitors network or system activities for malicious actions or policy violations and generates alerts, but does not typically take active blocking measures.

A system that monitors network traffic for malicious activity and can actively block or prevent detected threats, unlike an IDS which only alerts.

The practice of dividing a computer network into smaller subnetworks or segments to improve security, limit lateral movement, and contain breaches.
