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 ...
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 ...
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 ...
Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [3] NAC might integrate the automatic remediation process (fixing non-compliant nodes before allowing access ...
Lattice-based access control. In computer security, lattice-based access control ( LBAC) is a complex access control model based on the interaction between any combination of objects (such as resources, computers, and applications) and subjects (such as individuals, groups or organizations). In this type of label-based mandatory access control ...
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 ...
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.
