This means understanding security gaps and opportunities so you can address them with technical controls -- yet, you're not so overloaded that your responsibilities for managing so many security systems are getting in the way of security. | {{course.flashcardSetCount}} What are the OWASP Security Design Principles? One of the first steps in security design is developing a security plan.

This security design principle says that the security mechanisms design to protect the system should not interfere with the working of the user every now and then. The technical requirements of a network can be understood as the technical aspects that a network infrastructure must provide in terms of security, availability, and integration.
