Access Token Manager
In computer systems security, role-based access control (RBAC) or role-based security is an approach to restricting system access to authorized users, and to implementing mandatory access control (MAC) or discretionary access control (DAC). 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. RBAC can be used to facilitate administration of security in large organizations with hundreds of users and thousands of permissions. Although RBAC is different from MAC and DAC access control frameworks, it can enforce these policies without any complication. Design Within an organization, roles are created for various job functions. The permissions to perform certain operations are assigned to spe ...

Mandatory Access Control
In computer security, mandatory access control (MAC) refers to a type of access control by which a secured environment (e.g., an operating system or a database) constrains the ability of a ''subject'' or ''initiator'' to access or modify on an ''object'' or ''target''. In the case of operating systems, the subject is a process or thread, while objects are files, directories, TCP/ UDP ports, shared memory segments, or IO devices. Subjects and objects each have a set of security attributes. Whenever a subject attempts to access an object, the operating system kernel examines these security attributes, examines the authorization rules (aka ''policy'') in place, and decides whether to grant access. 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 p ...

XACML
__NOTOC__ The eXtensible Access Control Markup Language (XACML) is an XML-based standard markup language for specifying access control policies. The standard, published by OASIS (organization), OASIS, defines a declarative fine-grained, attribute-based access control policy language, an architecture, and a processing model describing how to evaluate access requests according to the rules defined in policies. XACML is primarily an attribute-based access control system. In XACML, attributes – information about the subject accessing a resource, the resource to be addressed, and the environment – act as inputs for the decision of whether access is granted or not. XACML can also be used to implement role-based access control.See for example In XACML, access control decisions to be taken are expressed as Rules. Each Rule comprises a series of conditions which decide whether a given request is approved or not. If a Rule is applicable to a request but the conditions within t ...

PERMIS
PERMIS (PrivilEge and Role Management Infrastructure Standards) is a sophisticated policy-based authorization system that implements an enhanced version of the U.S. National Institute of Standards and Technology (NIST) standard Role-Based Access Control (RBAC) model. PERMIS supports the distributed assignment of both roles and attributes to users by multiple distributed attribute authorities, unlike the NIST model which assumes the centralised assignment of roles to users. PERMIS provides a cryptographically secure privilege management infrastructure ( PMI) using public key encryption technologies and X.509 Attribute certificates to maintain users' attributes. PERMIS does not provide any authentication mechanism, but leaves it up to the application to determine what to use. PERMIS's strength comes from its ability to be integrated into virtually any application and any authentication scheme like Shibboleth (Internet2), Kerberos, username/passwords, Grid proxy certificates and Pub ...

Identity Driven Networking
Identity driven networking (IDN) is the process of applying network controls to a network device access based on the identity of an individual or a group of individuals responsible to or operating the device. Individuals are identified, and the network is tuned to respond to their presence by context. The OSI model provides a method to deliver network traffic, not only to the system but to the application that requested or is listening for data. These applications can operate either as a system based user- daemon process, or as a user application such as a web browser. Internet security is built around the idea that the ability to request or respond to requests should be subjected to some degree of authentication, validation, authorization, and policy enforcement. Identity driven networking endeavors to resolve user and system based policy into a single management paradigm. Since the internet comprises a vast range of devices and applications there are also many boundaries an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AGDLP
AGDLP (an abbreviation of "account, global, domain local, permission") briefly summarizes Microsoft's recommendations for implementing role-based access controls (RBAC) using nested groups in a native-mode Active Directory (AD) domain: User and computer accounts are members of global groups that represent business roles, which are members of domain local groups that describe resource permissions or user rights assignments. AGUDLP (for "account, global, universal, domain local, permission") and AGLP (for "account, global, local, permission") summarize similar RBAC implementation schemes in Active Directory forests and in Windows NT domains, respectively. Details Role based access controls (RBAC) simplify routine account management operations and facilitate security audits. System administrators do not assign permissions directly to individual user accounts. Instead, individuals acquire access through their roles within an organization, which eliminates the need to edit a po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Risk-based Authentication
In authentication Authentication (from ''authentikos'', "real, genuine", from αὐθέντης ''authentes'', "author") is the act of proving an Logical assertion, assertion, such as the Digital identity, identity of a computer system user. In contrast with iden ..., risk-based authentication is a non-static authentication system which takes into account the profile (IP address, User-Agent HTTP header, time of access, and so on) of the agent requesting access to the system to determine the risk profile associated with that transaction. The risk profile is then used to determine the complexity of the challenge. Higher risk profiles leads to stronger challenges, whereas a static username/password may suffice for lower-risk profiles. Risk-based implementation allows the application to challenge the user for additional credentials only when the risk level is appropriate. The point is that user validation accuracy is improved without inconveniencing a user, and risk-based authenticat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capability-based Security
Capability-based security is a concept in the design of secure computing systems, one of the existing security models. A capability (known in some systems as a key) is a communicable, unforgeable token of authority. It refers to a value that references an object along with an associated set of access rights. A user program on a capability-based operating system must use a capability to access an object. Capability-based security refers to the principle of designing user programs such that they directly share capabilities with each other according to the principle of least privilege, and to the operating system infrastructure necessary to make such transactions efficient and secure. Capability-based security is to be contrasted with an approach that uses traditional UNIX permissions and access control lists. Although most operating systems implement a facility which resembles capabilities, they typically do not provide enough support to allow for the exchange of capabilitie ...

Organisation-based Access Control
In computer security, organization-based access control (OrBAC) is an access control model first presented in 2003. The current approaches of the access control In physical security and information security, access control (AC) is the action of deciding whether a subject should be granted or denied access to an object (for example, a place or a resource). The act of ''accessing'' may mean consuming ... 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. OrBAC allows the policy designer to define a security policy independently of the implementation. The chosen method to fulfill this goal is the introduction of an abstract level. * Subjects are abstracted into roles. A role is a set of subjects to which the same security rule apply. * Similarly, an activity is a set of actions to which the same security rule apply. * And, a view is a set of ...

Access Control List
In computer security, an access-control list (ACL) is a list of permissions associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. Each entry in a typical ACL specifies a subject and an operation. For instance, * If a file object has an ACL that contains, this would give Alice permission to read and write the file and give Bob permission only to read it. * If the Resource Access Control Facility (RACF) profile CONSOLE CLASS(TSOAUTH) has an ACL that contains, this would give ALICE permission to use the TSO CONSOLE command. Implementations Many kinds of operating systems implement ACLs or have a historical implementation; the first implementation of ACLs was in the filesystem of Multics in 1965. Filesystem ACLs A filesystem ACL is a data structure (usually a table) containing entries that specify individual user or group rights to ...

Research Triangle Institute
Research Triangle Institute, operating as RTI International, is a nonprofit organization headquartered in the Research Triangle Park in North Carolina, USA. RTI provides research and technical services. It was founded in 1958 with $500,000 in funding from local businesses and the three North Carolina universities that form the Research Triangle. RTI research has covered topics like HIV/AIDS, healthcare, education curriculum and the environment. History In 1954, a building contractor, met with the North Carolina state treasurer and the president of Wachovia to discuss building a research park in North Carolina to attract new industries to the region. They obtained support for the concept from the state governor, Luther Hodges, and the three universities that form the research triangle: University of North Carolina at Chapel Hill, Duke University and North Carolina State University. The Research Triangle Institute (now RTI International) was formed by the park's founders as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
