This article is very important, I shared it.

Enjoyed this read, it’s key to remember that some of these are design time vulnerabilities that you should consider and some are possible to miss in server / infrastructure setup like security http headers. Lots of angles to consider. Put your black hat on and start poking holes in your own project!

Just shared it with the team! It’s always good to remind ourselves this kind of things

Thank for sharing the article. It will be good guide for those who are starting with backend technology.

I can’t tell you the number of clients I have worked for, over the years that never implemented even the basic checks.
