Database security concerns the use of a broad range of information security controls to protect databases against compromises of their confidentiality, integrity and availability. [1] It involves various types or categories of controls, such as technical, procedural or administrative, and physical. Security risks to database systems include ...
The basic principle is that the key embodies a secret that is shared between the lock and the key, and the same principle underlies possession factor authentication in computer systems. A security token is an example of a possession factor. Disconnected tokens have no connections to the client computer. They typically use a built-in screen to ...
Authenticated Encryption (AE) is an encryption scheme which simultaneously assures the data confidentiality (also known as privacy: the encrypted message is impossible to understand without the knowledge of a secret key) and authenticity (in other words, it is unforgeable: the encrypted message includes an authentication tag that the sender can calculate only while possessing the secret key).
Zero trust security model. The zero trust security model, also known as zero trust architecture ( ZTA ), and sometimes known as perimeterless security, describes an approach to the strategy, design and implementation of IT systems. The main concept behind the zero trust security model is "never trust, always verify", which means that users and ...
The Central Authentication Service ( CAS) is a single sign-on protocol for the web. [1] Its purpose is to permit a user to access multiple applications while providing their credentials (such as user ID and password) only once. It also allows web applications to authenticate users without gaining access to a user's security credentials, such as ...
An authentication system is then classified as either offering or not offering a specific benefit within the categories of usability deployability and security. Measuring usability of web authentication systems will allow for formal evaluation of a web authentication system and determine the ranking of the system relative to others.
Web Authentication ( WebAuthn) is a web standard published by the World Wide Web Consortium (W3C). [1] [2] [3] WebAuthn is a core component of the FIDO2 Project under the guidance of the FIDO Alliance. [4] The goal of the project is to standardize an interface for authenticating users to web-based applications and services using public-key ...
Simple Authentication and Security Layer ( SASL) is a framework for authentication and data security in Internet protocols. It decouples authentication mechanisms from application protocols, in theory allowing any authentication mechanism supported by SASL to be used in any application protocol that uses SASL. Authentication mechanisms can also ...
