How do you handle role conflicts and segregation of duties in role-based access control?

由人工智能和领英社区提供技术支持

Role-based access control (RBAC) is a common method of managing user permissions and access to resources in an organization. RBAC assigns users to roles, and roles to permissions, based on their job functions and responsibilities. However, RBAC also poses some challenges, such as role conflicts and segregation of duties, that need to be handled carefully to ensure security and compliance. In this article, you will learn what role conflicts and segregation of duties are, why they are important, and how to handle them in RBAC.

1 What are role conflicts and segregation of duties?

Role conflicts occur when a user has two or more roles that grant them incompatible or conflicting permissions. For example, a user who has both the role of a developer and a tester may have access to both the source code and the test environment, which could compromise the integrity and quality of the software. Segregation of duties (SoD) is a principle that aims to prevent role conflicts by separating the tasks and permissions that are critical, sensitive, or risky among different users or roles. For example, a user who has the role of a cashier should not have the role of a manager who can approve refunds, as this could create a fraud opportunity.

Something I've found helpful is that any action has an implementation and a validation aspect. I am cognisant of this and always seek to separate these roles during change, project, and incident completion. An example would be validating all applications, services and systems after system patching in both development and production. The patching team patches all night. The next morning a validation bridge is opened and all teams validate on the bridge that their respective applications and services are working as expected. Those that are not can be addressed by the application team with the assistance of a sysadmin who is on the bridge also. This approach has decreased the amount of major incidents, and has added check and balances.

2 Why are role conflicts and segregation of duties important?

Role conflicts and segregation of duties are important for several reasons. First, they help to prevent unauthorized access, misuse, or abuse of resources and data by limiting the scope and power of each user and role. Second, they help to ensure accountability and auditability by creating clear and traceable records of who did what and when. Third, they help to comply with regulatory and industry standards, such as SOX, PCI-DSS, HIPAA, or ISO 27001, that require proper controls and safeguards over access and permissions. Fourth, they help to reduce errors and improve quality by ensuring that each task and permission is performed by the appropriate and qualified user or role.

3 How to identify role conflicts and segregation of duties?

The first step to handle role conflicts and segregation of duties is to identify them. This can be done by conducting a role-based access control testing (RBAC testing) process, which involves reviewing and analyzing the existing roles, permissions, users, and resources in the organization. RBAC testing can help to detect and report any potential or existing role conflicts, as well as any gaps or redundancies in the access and permission structure. RBAC testing can be done manually or with the help of automated tools, such as role mining, role engineering, or role analytics software.

One thing that we should consider is isolating domain admins from doing work in the environment that doesn't require domain admin access. This opens the highly privileged account to attack. These should be used only when necessary and privileged accounts with more appropriate access should be used for daily work.

4 How to resolve role conflicts and segregation of duties?

The second step to handle role conflicts and segregation of duties is to resolve them, which can be done by implementing one or more strategies such as role redesign, restriction, exception, or monitoring. Role redesign involves modifying the roles and permissions to reduce the conflicts. Role restriction limits access to certain resources or actions. Role exception grants temporary access to otherwise conflicting roles. Lastly, role monitoring tracks activities and transactions of a user with a role conflict. For example, a user with both the roles of a cashier and manager may be monitored by an auditor or alert system to ensure no fraud or abuse occurs.

5 How to maintain role conflicts and segregation of duties?

The third step to handle role conflicts and segregation of duties is to maintain them. This involves regularly reviewing and updating the roles, permissions, users, and resources in the organization, as well as the strategies and policies for resolving role conflicts and segregation of duties. This can help to ensure that the RBAC system is aligned with the changing needs and goals of the organization, as well as the evolving threats and risks in the environment. Maintaining role conflicts and segregation of duties can also involve conducting periodic RBAC testing, training, and awareness programs for the users and stakeholders.
