Getting Started with Web Security

Before we jump into specific attacks and defenses, let us take a step back and understand the big picture. Why does web security even matter? How do we practice safely? What does the security landscape look like right now?

This chapter is all about setting the foundation. Think of it as warming up before the real workout. We will talk about real world breaches and why they matter, how to set up a safe lab so you can practice without getting into trouble, and what the current threat landscape looks like.

But here is the thing I really want you to take away from this chapter. Web security is not just about memorizing a list of vulnerabilities. It is about developing a security mindset. That means always asking questions like:

• What could go wrong here?
• How could someone misuse this feature?
• What am I assuming that might not be true?
• If I were an attacker, what would I target?

Once you start thinking this way, you will notice security issues everywhere. Not just in code, but in everyday life. That is when you know the mindset is kicking in. And that is honestly more valuable than knowing any specific attack technique.

So let us start from the beginning. Why should you even care about web security?
