Role-based access control (RBAC) allows organisations to restrict access to certain systems, allowing only certain authorised users access to certain and specific information. Though the term may be little known among the mainstream, as a tool RBAC has the potential to protect the security of information organizations protect.
The following are five reasons why the use of RBAC is a natural fit any environment:
1. Improve the security of systems and applications
Do you know exactly who has access to what at information in every area of the organisation? Often when new employees need accounts, a copy of another account is made, which is called a “template user.” This creates a security risk since access to applications and systems are also copied and are often never revoked. RBAC allows IT administrators to quickly and easily see the resources that employees have available to them based upon their role in the organisation. This allows IT leaders to ensure that nobody has access to secure systems and applications that they are not supposed to, and make changes as necessary.
2. Security changes made easy
Employees frequently change roles and jobs within an organisation and subsequently need different access privileges. With RBAC in place, changes that occur are no longer difficult no matter how complicated the changes may be. Complex changes, such as a part-time employee working in two different departments, can also be handled without significant effort.
3. Audit requirements easily met
Employing a role-based access control system makes meeting strict audit requirements easy. Every organisation needs to be able to show that their information is secure. RBAC easily ensures that secure information remains that way, and organisational leaders can easily access this information for audits, if needed.
4. Increase employee productivity
Assigning new employees their correct access rights can be time consuming both the IT employee and the end user. With RBAC, new employees do not have to wait for their privileges to be assigned and are able to begin working with the necessary applications, such as word processing, email and departmental shares, even if they are assigned more specific privileges later on. RBAC allows for automated access to these “base” systems and allow new system users to be able to get to work in a much more efficient manner than a paper-based access system, which can take days to set up and deploy.
5. Reduce internal costs, cut unneeded programs and licenses
With RBAC, an organisation’s IT leaders can determine which internal applications are being used and how often to determine which are necessary for their business needs. Programs deemed unnecessary can be eliminated or have licensing counts reduced, thus saving the organisation money while creating additional efficiencies.
