Broken Access Control

Definition of Broken Access Control

Broken access control occurs when users can perform actions or access data they aren't supposed to due to insufficient security restrictions. This can range from a standard user gaining access to an admin's functionalities to an external user retrieving sensitive files that should be confidential. It's like having a bank vault that should only open with the correct code, but due to a flaw, it swings wide open with a gentle push.

Origin of Broken Access Control

The origin of broken access control can be traced back to the early days of computer networks when systems were less complex, and security was not the foremost concern. As the internet evolved, so did the complexity of systems and the importance of stringent access controls. Broken access control was formally recognized as a security issue with the inception of the Open Web Application Security Project (OWASP), which included it in their list of top 10 web application security risks.

Practical Application of Broken Access Control

In the realm of web applications, a practical application of understanding broken access control is to prevent security breaches. For instance, a banking app must ensure that a user can only view and manage their accounts, not the accounts of others. Developers apply role-based access control checks, stringent authentication, and authorization techniques to ensure that each user session is correctly managed and limited to its respective privileges.

Benefits of Broken Access Control

Identifying and addressing broken access control can significantly bolster an application's security. It helps in safeguarding personal and business data, maintaining user trust, and ensuring compliance with data protection regulations. Effective access control is not just a barrier but also a facilitator for secure and efficient user interaction with systems, creating a safe digital environment where users can confidently perform their tasks.

FAQ

Broken access control can be caused by misconfigurations, flawed design, software bugs, or the failure to properly implement security controls like authentication and authorization mechanisms.

Preventing broken access control requires a multi-layered approach including thorough testing, code reviews, adopting least privilege principles, regular updates, and employing robust authentication and authorization frameworks.

Not exactly. An application with broken access control may have some level of security in place, but due to certain flaws, the restrictions on what authenticated users are allowed to do are not enforced correctly. This differs from having no security, where there are no measures in place to protect data or functionalities from the outset.
