The last few years the biggest buzzword was shifting left. You have seen it everywhere. The concept is pretty simple when you think about the evolution of application security. We started out with a huge focus on penetration testing and providing a report back to the development team.

This method of app security was easy because it was in a time where … [Read more...] about Don’t Shift Left, Expand

Hashing is used to create data signatures or comparison only features. For example, user passwords … [Read more...] about What is the difference between encryption and hashing?
When you think of application security testing, one of the most common tools is a web proxy. Whether it is Burp Suite from Portswigger, ZAP from OWASP, Fiddler, or Charles Proxy, a proxy is heavily used. From time to time, you may find yourself testing a locally running application. Outside of some test labs or local development, this isn't really that common. But if you do find yourself testing a site on localhost, you may run into a roadblock in your browser. If you are using a recent version … [Read more...] about Proxying localhost on FireFox
