A sailor checks an identification card (ID) before allowing a vehicle to enter a military installation. In physical security and information security, access control ( AC) is the selective restriction of access to a place or other resource, while access management describes the process. The act of accessing may mean consuming, entering, or ...
Basic access control. Basic access control (BAC) is a mechanism specified to ensure only authorized parties [1] can wirelessly read personal information from passports with an RFID chip. It uses data such as the passport number, date of birth and expiration date to negotiate a session key. This key can then be used to encrypt the communication ...
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.
Tunnels. PPP. MAC. more... v. t. e. In computing, Internet Protocol Security ( IPsec) is a secure network protocol suite that authenticates and encrypts packets of data to provide secure encrypted communication between two computers over an Internet Protocol network. It is used in virtual private networks (VPNs).
Attribute-based access control. Attribute-based access control ( ABAC ), also known as policy-based access control for IAM, defines an access control paradigm whereby a subject's authorization to perform a set of operations is determined by evaluating attributes associated with the subject, object, requested operations, and, in some cases ...
Access control matrix. In computer science, an access control matrix or access matrix is an abstract, formal security model of protection state in computer systems, that characterizes the rights of each subject with respect to every object in the system. It was first introduced by Butler W. Lampson in 1971. [1]
Computer access control. In computer security, general access control includes identification, authorization, authentication, access approval, and audit. A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject ...
Mandatory access control. In computer security, mandatory access control ( MAC) refers to a type of access control by which the operating system or database constrains the ability of a subject or initiator to access or generally perform some sort of operation on an object or target. [1] In the case of operating systems, a subject is usually a ...
