Authentication Dial-Up Networking Services (RADIUS) is a client-server architecture that verifies remote user identity. It allows authorized user profiles to be hosted on a home server, and if credentials are valid, access is granted. After three failed login attempts, the user file is blocked. RADIUS ensures secure remote access to databases and key servers for […]
RADIUS is a network protocol for authentication, authorization, and accounting between a client and network service. It’s used on untrusted systems, like the Internet, to manage communication through AAA. The protocol verifies identity, determines access parameters, and monitors usage for billing purposes. RADIUS (Remote Authentication Dial In User Service) is a network protocol that handles […]
An authentication server controls access to a computer network, with goals of authorization, privacy, and non-repudiation. It can be software on a network access point, and uses algorithms like passwords or Kerberos. Proxy servers can also act as authentication servers. Security requirements should be analyzed before implementation. An authentication server is a device that controls […]
An authentication server controls network access, providing authorization, privacy, and non-repudiation. It can be hardware or software-based and use various algorithms, including passwords and Kerberos. Proxy servers can also act as authentication servers, and security requirements should be analyzed before implementation. An authentication server is a device that controls who can access a computer network. […]
A proxy server acts as a receptionist for internet users, verifying their credentials and directing them to the appropriate website. It can also provide encryption, prevent DoS attacks, and filter content for children or employees. A proxy server is analogous to the receptionist in an office. The receptionist checks the identification and credentials of the […]
Kerberos uses authentication tickets to prove identity and permissions between client and server. There are two types of tickets: TGTs and session tickets. A key distribution center (KDC) manages the ticketing system, granting TGTs and session tickets. The system is encrypted, but if the KDC is compromised, all users’ identities and passwords are at risk. […]
Anonymous authentication allows users to access web pages or services without revealing their identity, protecting personal safety and security. It also prevents tracking and monitoring of online behavior, making it useful for professionals and children. However, websites using anonymous authentication cannot limit access or identify users. Anonymous authentication is the process of confirming a user’s […]
Authorized capital is the maximum amount of funds a company can use for ongoing operations or issue to shareholders, as specified in constitutional documents. It is often expressed in the currency of the company’s home country and is controlled to ensure the business remains viable. Shareholders refer to authorized capital as nominal capital, which can […]
A merchant authorization is when a card issuer records an authorization amount as unavailable to the cardholder until the merchant resolves the transaction or the card issuer releases the hold. The transaction typically settles within a few days for debit card purchases, and a clearance reversal can stop a merchant’s clearance. Problems can arise with […]
