The Importance of Role-Based Access Controls in Securing Your Data

With RBAC, it’s easier to meet compliance standards for data security, privacy, accessibility, and availability. It also reduces IT workload and minimizes user downtime by avoiding the need to manage personalized permissions for every individual user. Rolling out a complete RBAC implementation is an enormous task, so work through it in stages to minimize excessive workload and business interruption. Start by addressing your most critical networks and applications first.

Security

Role-based access control (RBAC) is an alternative to the traditional model that grants security permissions to users based on their identity. It focuses on the principle of least privilege, which dictates that employees should only have access to the software, files, or actions required to perform their jobs. It also allows for a more manageable and simplified approach to security administration, eliminating the need for users to be assigned specific permissions individually. When properly implemented, role-based access controls can offer several significant benefits to both users and IT administrators. The system can help users do their jobs more efficiently without asking for or waiting for approvals. It also prevents them from accidentally navigating to inappropriate or confidential information. For IT personnel, it can make it easier to comply with general and industry-specific data protection regulations, such as GDPR, PIPEDA, and 23 NYCRR 500. However, it is essential to remember that RBAC requires some additional administration compared with the traditional method. It is essential to inventory the systems and processes that require access and work with management and human resources to identify roles that best meet those needs. These roles should be assigned to employees with appropriate authority, then permissions should be mapped to those roles.

Compliance

A sound role-based access control system enables you to limit access based on roles. This reduces cybersecurity risk by making it harder for cyber-attacks to spread. It also ensures that employees can only perform the tasks required by their jobs, avoiding the danger of accidental or malicious data leaks. While implementing RBAC, you must carefully consider the different roles and their privileges to ensure they fit your organization. This includes user types, security clearances, and financial knowledge. Then, you must implement the best governance processes to ensure changes in a role’s permissions are authorized and kept on track even as your company grows. Both RBAC and Attribute-based Access Control (ABAC) use policies to define access levels for users, roles, operations, objects, and permissions. However, RBAC is typically used for larger organizations with a more structured hierarchy.

In contrast, ABAC can be used in smaller environments where access permissions may need to be adjusted based on changing circumstances. In both models, you must ensure that all roles have a purpose and are maintained regularly. This is important because the granular access provided by a well-mapped role prevents users from accessing inappropriate data or functionality. It also helps to keep your organization on track with your compliance goals by preventing the unauthorized sharing of sensitive information.

Automation

Role-based access control models allow organizations to reduce the risk of security breaches by ensuring users have only the minimum permissions needed for their job duties. This ensures that unauthorized access by malicious insiders can’t harm the business or expose sensitive information to third parties. Organizations can also avoid compliance issues and fines by ensuring that only the right people can access the necessary information. Role-based access control’s benefits include reduced costs and overhead, higher security, and improved productivity. It also helps with regulatory and statutory compliance, essential for companies handling third-party data. An excellent way to implement RBAC is by inventorying your system, including programs, servers, documents, and files. Once you’ve determined what systems to protect, you can begin identifying roles and assigning permissions. Reviewing and adjusting them regularly is essential to ensure that your roles accurately reflect current job responsibilities and duties. A significant difference between RBAC and MAC is that RBAC allows you to customize access on a user-by-user basis, while MAC limits access to a predefined policy. This makes it easier for businesses to change user permissions based on changes to job responsibilities or other factors, which can lead to less data loss. It also enables you to provide a more streamlined onboarding process for new employees, as they can access the correct systems on day one.

Scalability

Roles are a helpful tool for simplifying the process of granting permissions. But it’s important to remember that roles don’t replace the need for access management policies and permissions. Permissions are the foundation of RBAC; they define what a role can and cannot do, such as opening embedded links in documents or deleting them. They also determine what objects and operations a user can access. For example, a contributor may be granted the ability to edit the content of a document (an operation) but not the permission to open or delete it (an object). It is also vital to note that although using roles makes it easier for data teams to access users, the system will still require monitoring and adjusting as the organization grows and changes. This requires a centralized privileged access management (PAM) solution that can automate these processes, monitor identities and permissions in real time, and enforce the principle of least privilege. Implementing a PAM strategy based on roles will allow you to meet compliance standards like PCI DSS, ISO-IEC 27001, NERC-CIP, GDPR, and others in just a few clicks. It will also help you improve your security posture, ensure business continuity, and reduce operational overhead. The key to success is to include a recurring cadence of reviewing and iterating your RBAC.
