@rick.theengineer: Your firewall let the attack in, and it was doing its job perfectly 👇 A firewall and a WAF both protect your server, but they look at completely different things. 🚧 A network firewall is a checkpoint. It only reads the outside of each request: → where it's coming from (IP address) → where it's going, which port, which protocol → allow web traffic on 443, allow admin access only from the office, block everything else It's fast, and it closes every door you don't need. But your store has to accept web traffic, so port 443 stays open to everyone. A real customer and an attacker look exactly the same there. 🩻 A WAF (web application firewall) is the X-ray. It reads what's inside the actual web request: the URL, headers, cookies and form data. That's how it catches what a firewall never could: 💉 SQL injection: database commands typed into your login box 📜 Cross-site scripting: hidden JavaScript in a product review that runs in other shoppers' browsers 🤖 Credential stuffing: a bot trying thousands of stolen passwords per minute To read HTTPS traffic, the WAF usually sits right in front of your web server and decrypts it first. 💡 The firewall decides who can reach your server and through which doors. The WAF inspects what they say once they're through the web door. That's why real systems use both: the firewall shrinks the attack surface, and the WAF guards the one door you can never close. Is your app sitting behind a WAF, or just a firewall? 👀 #cybersecurity #firewall #websecurity #webdev #techexplained
