Defining and granting access rights is a constant challenge for IT departments. Managing access rights based on a role-based approach makes controlling system authorisations for users in complex IT environments clear and simple. On one hand, as many regular users – whether employees, external contractors or others – require the same or similar access rights to perform their work, the assignment of access rights can be greatly simplified by grouping employees based on their tasks and associated competences within the organisation.
On the other hand, a lack of access control or automatic provisioning of rights and access can be costly and risky for the enterprise in a number of ways. It means that new employees and contractors may not be up and running as quickly as necessary, they may gain access to systems they shouldn’t have access to, they may retain their access rights when they change roles or leave the organisation, and they may inadvertently compromise the organisation’s security profile.
The power of RBAC
Role-based access control is a procedure for managing and controlling access to files or services. Instead of giving users in the network direct access rights to various systems or making spontaneous decisions about who can access what and for how long, access is granted according to a role previously assigned to the user. When used systematically, RBAC reduces the risk of a user being granted too much access and thus promotes the implementation of a least privilege strategy.
With clearly defined roles, protocols are created that specify exactly which role is suitable for which type of user, which prevents inappropriate inheritance of authorisations. In the event of a compromise, authorisations can also be blocked extremely quickly and on a large scale, effectively preventing the spread of cyberattacks. This is the reason why the RBAC concept is often used, particularly in companies with more than 500 employees. This ensures that employees always have the rights they need and that there are no interruptions to operations.
- RBAC provides flexibility
RBAC allows organizations to define roles and permissions based on their specific business requirements and security policies. Roles can be tailored to reflect different job functions, departments, or projects, and permissions can be fine-tuned to accommodate variations in access needs across different user groups.
With RBAC, companies can react more flexibly to employee changes according to the Joiner, Mover Leaver (JML) process. Especially when employees join, change departments or leave the company, RBAC makes work much easier and safer. At the same time rights can be granted and withdrawn at any time via role memberships, which makes RBAC very adaptable and dynamic.
Role-Based Access Control also makes the time-consuming assignment of individual authorisations obsolete by predefined authorisations to roles once and can be rolled out to several people in one go or withdrawn again. If the roles are named in a way that is easy to understand, this also increases Transparency and traceability on the user side.
- RBAC Increases security and efficiency
The allocation of individual authorisations without RBAC is not only time-consuming. It also means less control and overview of who has access to what. It also leaves room for errors and over-authorisation. Thus, security gaps can arise if the individual authorisations are no longer withdrawn or are retained for longer than necessary. If users are given too many authorisations, this can lead to errors.
With a well thought-out and predefined authorisation concept, the company not only saves work but is also on the safe side: access rights are defined exclusively via the role concept. Over-authorisation of individual employees is thus avoided in accordance with the Principle of Least Privilege (PoLP) in order to fulfil compliance requirements.
In this way, RBAC helps to significantly increase efficiency and security in IT and throughout the entire company. Changes are made automatically, rights no longer have to be applied for and assigned individually and the waiting time for approval is also eliminated. This not only makes managing access rights easier, but more error-resistant, as well.
- RBAC reduces complexity
Role-based access control includes role authorisations and user roles and can be used to meet a variety of company requirements, from security and compliance to efficiency and cost control. With role-based access control, organisations reduce both the complexity of assigning access rights and the associated costs. It provides the ability to review access rights to ensure compliance with various regulations and streamline processes so that new employees are up and running from day one by pre-defining which systems the new employee should have access to based on their role in the organisation.
- RBAC improves compliance
RBAC facilitates auditing and reporting by providing a structured framework for access control. Audit logs can track user activities and access attempts based on role assignments and permissions, enabling organizations to monitor compliance with regulatory requirements and internal policies. RBAC helps demonstrate accountability and transparency by documenting who has access to sensitive resources and how access is being used, which is essential for compliance audits and investigations.
- RBAC supports Segregation of Duties (SoD)
RBAC supports segregation of duties by defining roles with mutually exclusive sets of permissions. This prevents conflicts of interest and reduces the risk of fraud and errors by ensuring that no single user has excessive privileges that could be abused. SoD controls help prevent unauthorized activities such as unauthorized transactions, data tampering, and fraud, thereby enhancing security.
Having in mind the above listed advantages, we can conclude that RBAC is important for businesses in terms of enhanced security, facilitated compliance with regulatory requirements, mitigated risks, and improved operational efficiency. By implementing RBAC, businesses can strengthen their security posture, protect sensitive information, and maintain trust with customers, partners, and regulatory authorities.
