In computer security, organization-based access control (OrBAC) is an access control model first presented in 2003. The current approaches of the access control rest on the three entities ( subject , action , object ) to control the access the policy specifies that some subject has the permission to realize some action on some object.
A database management system, in its access control mechanism, can also apply mandatory access control; in this case, the objects are tables, views, procedures, etc. In mandatory access control, the security policy is centrally controlled by a policy administrator and is guaranteed (in principle) to be enforced for all users.
These components and events were the "interface specifications" or "ispecs" and contained the database definitions, screen designs, and business rules of the application system. LIRC (Logic and Information Report Compiler) was part of LINC and was developed to allow the programmer to produce reports (e.g. "purchase orders", "invoices", "credit ...
Logical access controls enforce access control measures for systems, programs, processes, and information. The controls can be embedded within operating systems, applications, add-on security packages, or database and telecommunication management systems.
Role-based access control is a policy-neutral access control mechanism defined around roles and privileges. The components of RBAC such as role-permissions, user-role and role-role relationships make it simple to perform user assignments. A study by NIST has demonstrated that RBAC addresses many needs of commercial and government organizations. [4]
Network access control (NAC) is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement.
Common physical security access control with a finger print 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.
In computer systems security, Relationship-based access control (ReBAC) defines an authorization paradigm where a subject's permission to access a resource is defined by the presence of relationships between those subjects and resources. In general, authorization in ReBAC is performed by traversing the directed graph of relationships.
