Networks allow computers to communicate. Understanding networking is important in cybersecurity because most attacks happen over networks.
- IP Address: Like a home address for your device on the network.
- Port: A door to a specific service or application.
- Protocol: Rules for communication, e.g., HTTP, HTTPS, SSH.
Example:
A website uses port 443 for HTTPS traffic. Hackers can try to exploit open ports, so you need to protect them.
