I just completed How Websites Work room on TryHackMe! To exploit a website, you first need to know how they are created. https://t.co/ZEMj1QUt9m #tryhackme via @tryhackme
Stateful = remembers previous interactions (Think personal relationship)
Stateless = every request is treated independently with no past memory (Who are you stranger?)
Will you remember me if I give you a 🍪?
Networking Layer Continued 🔌
Why the switch from MAC → IP❓
A data packet can travel through many different networks, meaning it must change/exchange MAC at each stop. IP, on the other hand, stays the same as it travels across networks.

OSI Layer 3: Network
This layer is where IP addresses are used. Routers handle sending data between different networks using these IP addresses.

Data Link Continued:
How does this work?
Simple answer:
Each device has a unique MAC address, like a fingerprint.
When one device sends data, it first asks, “Who has this MAC address?”
Once it knows, the MAC is attached to the data so it goes straight to the right device.
OSI layer 1: Physical
This layer deals with the physical hardware and explains how raw bits of data are converted to signals to eventually be sent in packets across the network.
Think Matrix!

When it comes to Carna bot I'm curious if each country quietly fixed it on their own or if they just ignored it all together?
#CyberSecurity#cyberquestions
@thatoppsdev I am currently just diving into security for a certification. I have a little knowledge in development but am moving towards cyber security.
🧠Memory Summary :
CIA Triad
1. Confidentiality - Privacy: Who can see it?
2. Integrity - Trust: Is it Unchanged?
3. Availability - Access: Can I get to it?

Then there is Non-repudiation that says "You can’t deny that you did something once there’s proof that you did it."
Non = "not"
repudiate (repudiare) = "to deny"
-ion = "the act of"
