Access Control Systems: Security, Identity Management and by Messaoud Benantar

By Messaoud Benantar

Access regulate structures: safety, id administration and belief Models offers a radical advent to the principles of programming structures safeguard, delving into identification administration, belief versions, and the speculation at the back of entry regulate types. The publication info entry regulate mechanisms which are rising with the newest web programming applied sciences, and explores all versions hired and the way they paintings. the most recent role-based entry keep an eye on (RBAC) usual can also be highlighted.

This special technical reference is designed for safeguard software program builders and different safeguard execs as a source for environment scopes of implementations with recognize to the formal versions of entry keep watch over platforms. The ebook is usually compatible for advanced-level scholars in safety programming and approach design.

It encompasses the following assurance families: Ö Covert channel analysis Addresses the potential for illicit information flows which can be exploited to breach the security defenses implemented by the TOE; 34 1. Foundations of Security and Access Control in Computing o Misuse Investigates the existence of TOE configurations that may lead to insecure operations when users and administrators reasonably believe the TOE is operating in a secure manner; o Strength of TOE security functions Provides a measurement as to the strength of the mechanisms implementing the security functions of the TOE; Ö Vulnerability analysis An assessment to determine whether any identified vulnerabilities of the TOE can be exploitable to cause the violation of the security policy intended to be enforced by the TOE.

In either case, one entity performs functions on behalf of another entity. Recall that acting on behalf of an entity implies the use of that entity's security context and hence its identity and entitlements. Masquerading under someone's identity, however, is a security violation. The key distinction between delegation and masquerading is that delegation implies the presence of two entities both of which are aware of one another and one is consenting that the other assumes its identity. Masquerading, on the other hand, happens when an entity assumes the identity of another entity without explicit or implicit consent.

The computational aspects of asserting each of these authentication factors have no commonality. Passwords rely on secretive information, while physical tokens are based on the premise that the token is safely kept and guarded by its owner. Biometrics, on the other hand, depends on the uniqueness of biological properties among humans. 1 and contrast them in terms of benefits and disadvantages. Regardless of which authentication factor is used, remote authentication requires a secure channel for the transmission of secrets or the distinguishing biometric attributes or some derivative thereof Such a secure channel generally requires end-to-end encryption of exchanged information.
