In contrast, basic access authentication uses the easily reversible Base64 encoding instead of hashing, making it non-secure unless used in conjunction with TLS. Technically, digest authentication is an application of MD5 cryptographic hashing with usage of nonce values to prevent replay attacks. It uses the HTTP protocol.
A secure access service edge ( SASE) is technology used to deliver wide area network (WAN) and security controls as a cloud computing service directly to the source of connection ( user, device, Internet of things (IoT) device, or edge computing location) rather than a data center. [1] It uses cloud and edge computing technologies to reduce the ...
SOA security. SOA security addresses the issue of combining services in a service-oriented architecture (SOA) in a secure manner. These issues arise as an effect of the main premise of SOA, which is to erase application boundaries and technology differences. Prior to the application of SOA methodologies, security models have traditionally been ...
A gateway is a piece of networking hardware or software used in telecommunications networks that allows data to flow from one discrete network to another. Gateways are distinct from routers or switches in that they communicate using more than one protocol to connect multiple networks [1] [2] and can operate at any of the seven layers of the OSI ...
Network security consists of the policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. [1] Network security involves the authorization of access to data in a network, which is controlled by the network administrator.
Brewer and Nash model. The Brewer and Nash model was constructed to provide information security access controls that can change dynamically. This security model, also known as the Chinese wall model, was designed to provide controls that mitigate conflict of interest in commercial organizations and is built upon an information flow model.
Secure by design, in software engineering, means that software products and capabilities have been designed to be foundationally secure. Alternate security strategies, tactics and patterns are considered at the beginning of a software design, and the best are selected and enforced by the architecture, and they are used as guiding principles for ...
The following outline is provided as an overview of and topical guide to computer security: Computer security is commonly known as security applied to computing devices such as computers and smartphones, as well as computer networks such as private and public networks, including the whole Internet. The field covers all the processes and ...
