The OWASP Top 10, Explained for People Who Ship Code

The OWASP Top 10 is the industry's shared list of the most critical web application risks. If you write code for a living, it is the single most useful security document to internalise.

Broken access control tops the list for a reason: it is everywhere and it is devastating. Always check authorisation on the server, for every request, for every object.

Injection remains stubbornly common. The fix is old and boring and works: parameterised queries, everywhere, no exceptions.

Security misconfiguration and vulnerable dependencies round out the risks most teams actually hit. Automate the checks so they happen on every commit.

Our Secure Coding for Developers course walks through all ten with real vulnerable code you fix yourself.
