FGAC has been integrated into several relational access control models, such as, for instance, the purpose-based model proposed in [6], and the action aware access control model in [9].
To reduce the energy cost of underwater acoustic sensor networks (UWSNs), the duty cycle (i.e., periodic wake-up and sleep) concept has been used in several medium access control (MAC) protocols.
Specifically in the domain of policy-based access control, several other authors have also focused on the problem of policy decomposition and distribution.
These pieces of software should have several features such as access control, metadata storage on the produced reads, quality control including known bias verification and standard analysis.
Safety analysis has been the main research area in access control for several decades.
It also provides access control and several collaboration features, such as a wikis and basic task management tools for every project.
In order to improve performance of multiple hop systems, several control methods on medium access control (MAC) layer have been proposed, i.e, S-MAC [3], T-MAC [4], B-MAC [5], X-MAC [6], Wise-MAC [7], etc.
However, the applicability of XACML is still not clear in collaborative and distributed environments composed of several security domains sharing the access control over some specific resources.
FreeBSD provides several security-related features including access control lists (ACLs), security event auditing, extended file system attributes, mandatory access controls (MAC) and fine-grained capabilities.
The architecture addresses the power-saving issue on several protocol layers, including network, medium access control (MAC), and physical layers.
