OWASP TOP 10: Access control vulnerabilities ~2024

Access control is a critical aspect of modern information security, determining who is authorized to access sensitive data, systems, and facilities.

The OWASP Top 10 provides rankings of—and remediation guidance for—the top 10 most critical web application security risks. Leveraging the extensive knowledge and experience of the OWASP's open community contributors, the report is based on a consensus among security experts from around the world.

What is Access Control?

Access control is a security technique that regulates who or what can view or use resources in a computing environment. It is a fundamental concept in security that minimizes risk to the business or organization.

There are two types of access control: physical and logical. Physical access control limits access to campuses, buildings, rooms and physical IT assets. Logical access control limits connections to computer networks, system files and data.

A comprehensive course on access control would cover the following topics:

• Introduction to access control: Explanation of access control concepts and importance in information security.

• Types of access control: Overview of the different access control models, such as discretionary access control, mandatory access control, role-based access control, and others.

• Authentication: Explanation of the various authentication methods, including username and password, biometric authentication, smart cards, and others.

• Authorization: Description of how authorization works, including access control lists, access control matrices, and role-based authorization.

• Access control technologies: Overview of the various access control technologies, including firewalls, intrusion detection systems, and other security measures.

• Physical access control: Overview of the measures used to control physical access to sensitive areas, including access cards, biometrics, and other identification methods.

• Network access control: Explanation of how access control is implemented in network systems, including the use of virtual private networks, firewalls, and other security measures.

• Access control in cloud computing: Overview of the challenges and solutions of implementing access control in cloud computing environments.

• Compliance and audits: Explanation of the various regulations, standards, and best practices related to access control and how they are audited and enforced.

• Case studies and real-world scenarios: Discussion of real-world examples of access control implementation, including lessons learned and best practices.

This course would also provide hands-on experience through lab exercises and case studies, allowing students to apply the concepts they have learned to real-world scenarios. With a comprehensive understanding of access control, students will be well-equipped to secure their own systems and data, and protect against threats such as unauthorized access, data theft, and malicious attacks.
