Diameter
Diameter: Diameter is an authentication, authorization, and accounting (AAA) protocol designed as an upgrade to RADIUS. While it offers advancements like better security, scalability, and flexibility, Diameter is predominantly employed in mobile IP-based networks rather than replacing RADIUS in all contexts. RADIUS remains widely used, particularly in traditional network environments.
Distance-Vector Routing Protocol
Distance-Vector Routing Protocol: A network routing protocol that calculates the best path for data delivery by using metrics or distances. Each router communicates with its immediate neighbors to exchange information about network topology. Changes in the network are communicated across routers to prevent loops and ensure reliable data transmission.
Dictionary Attack
Dictionary Attack: An attack that uses a list of predefined values (often common or predictable passwords) in an attempt to gain unauthorized access to a system. Attackers systematically try all the words or phrases from this ‘dictionary’ against a user account or encrypted file. While the method can be time-consuming, its success rate is considerably […]
Distributed Data Processing Network
Distributed Data Processing Network: A computational network structure in which data processing tasks are divided and managed across multiple geographically dispersed computers or nodes. Each node in the network works on a portion of the overall task, and the nodes may communicate with each other to share resources, balance load, and provide redundancy. This type […]
Differential Cryptanalysis
Differential Cryptanalysis: A method of analyzing and potentially breaking cryptographic systems, especially symmetric key schemes. It involves the study of how differences in an input can affect the resultant difference in the output. By observing these differences, an attacker might be able to infer the secret key used for encryption, thereby decrypting the contents without […]
Distributed Denial-of-Service (DDoS) Attack
Distributed Denial-of-Service (DDoS) Attack: A malicious attempt to disrupt normal traffic to a targeted server, service, or network by overwhelming the target or its surrounding infrastructure with a flood of internet traffic. DDoS attacks are performed using multiple compromised computer systems as sources of attack traffic, which could include computers and other networked resources such […]
