Yesterday I revisited the fundamentals of HTTP Requests.

Today I explored another layer of web security: HTTP Security Headers: the guards against XSS, clickjacking, insecure redirects & data leaks.

Yesterday, I revisited the foundations of HTTP Requests.
Today, I shifted to the other side of the communication flow: HTTP Responses: how servers talk back to clients, and the subtle clues these messages give attackers.

Day 61 of Learning:

Today I explored two OSINT (Open-Source Intelligence) tools that highlight just how much information is available online if you know where to look.

Day 59 of Learning:
I explored WhatWeb (aggression level 3) in my lab environment to understand the depth of reconnaissance possible.

Key findings included:
🔵 HTTP headers & server banners
🔵 TLS certificate details

Here's a little math problem about GRID 🤔

Multiple agentic capabilities available in one place
Data sources across industries
+ Reasoning to bring it all together

Day 52 of My Cybersecurity Journey – The Power of Reporting:

Let’s talk about something that separates script kiddies from professionals.
How we report findings after a penetration test.

It’s not just what you find - it’s how you communicate it.🧵👇
