Access Control Testing: Principles, Vulnerabilities & Tools
Blog post from Keploy
Access control, or authorization, is a vital aspect of application security that ensures users only access resources they are permitted to use, preventing unauthorized data exposure and other security risks. The text provides a comprehensive overview of access control testing, highlighting principles such as least privilege, separation of duties, and role-based access control (RBAC). It explains different access control types, including discretionary, mandatory, role-based, attribute-based, and rule-based access controls, and underscores common vulnerabilities like broken access control and insecure direct object references (IDOR). Various testing methodologies, both manual and automated, are discussed, along with tools like Burp Suite, OWASP ZAP, and Keploy, which aid in identifying and mitigating access control vulnerabilities. The importance of regular security assessments, multi-factor authentication, and centralized access control management is emphasized to strengthen application security. The text also explores how access control mechanisms adapt to microservices architecture and the role of user feedback in refining access control policies.
