CSP
Content Security Policy (CSP) is a security feature that helps protect websites from various types of attacks. Think of it as a security guard for websites that controls what content can be loaded and from where. When you see CSP mentioned in a resume, it usually means the candidate has experience making websites more secure. It's similar to setting up rules about who can enter a building and what they can bring in. This is increasingly important as more companies prioritize web security to protect their users' data.
