Web Security: Common Vulnerabilities And Their Mitigation - Direct object reference mitigations

The video tutorial discusses three key techniques to mitigate security risks: authorization, indirection layers, and randomized identifiers. Authorization ensures users can only access data they are permitted to, preventing unauthorized access. Indirection layers add a mapping layer between internal and external IDs, protecting sensitive data. Randomized identifiers replace predictable IDs with random strings to thwart brute force attacks. These methods, when combined, significantly enhance security by addressing direct object reference vulnerabilities.
