Which SDLC model is best and why?

As with most endeavors, good planning gets you only halfway to success. In IT, product quality largely depends on quality of planning, which is why the Software Development Life Cycle (SDLC) is so important.

What is Owasp firewall?

Description. A ”’web application firewall (WAF)”’ is an application firewall for HTTP applications. It applies a set of rules to an HTTP conversation. Generally, these rules cover common attacks such as Cross-site Scripting (XSS) and SQL Injection. While proxies generally protect clients, WAFs protect servers.

What is cyber threat modeling?

Threat modeling is a procedure for optimizing network security by identifying objectives and vulnerabilities, and then defining countermeasures to prevent, or mitigate the effects of, threats to the system. … The key to threat modeling is to determine where the most effort should be applied to keep a system secure.
