A Detailed Guide to the OWASP Top 10 - #4 Insecure Design Prevention

The video tutorial covers six key security principles for software development: least privilege, input validation, segregation of tenants, encryption, fail securely, and observing running code. Each principle is explained with examples, emphasizing the importance of minimizing privileges, validating inputs, separating environments, encrypting data, handling errors securely, and monitoring application use. These principles aim to prevent insecure designs and enhance software security.
