In this data access scheme, controlled access, which is generally used for genotype and phenotype databases (Mailman et al. [2007]; The International Cancer Genome Consortium [2010]), is different from open access: controlled access requires the database user to obtain prior permission or authorization from an appropriate committee when browsing or downloading registered data.
It defines technologies used for remote access such as remote authentication dial-in user service (RADIUS), terminal access controller access control system+ (TACACS+); secure sockets layer (SSL), VPN, and Citrix solutions.
In the second case (Figure 3), the MIH service access control is not applied through any access controller.
Moreover, controlled access is provided via access control mechanisms.
Three most widely used traditional access control models are: Discretionary Access Control (DAC), Mandatory Access Control (MAC), and Role Based Access Control (RBAC).
Role-Based Access Control (RBAC) and Mandatory Access Control (MAC) are widely used access control models.
The objectives include control access to information, manage user access rights, apply good access practices, control access to network services, control access to operating systems, and control access to applications and systems [42].
The FAPs can operate in three different access control modes: closed access, open access, and hybrid access [2, 3].
Inappropriate user accesses are inhibited by access control policies according the proposed access denying rules.
There are three main strategies: discretionary access control (DAC), mandatory access control (MAC), and role-based access control (RBAC).
