Using nmap to scan facebook.com

 Using nmap

-- My understanding of nmap

Nmap (network mapper) is like a detective for computer networks. It finds all the devices on a network and checks what doors (called ports) are open on them. It then guesses what type of devices they are , and even looks for security weakness. It is used to make sure networks are safe and working correctly.

In this blog, I will be using nmap to perform a scan on facebook.com

1. Using ping to verify reachability of facebook.com

facebook.com has been pinged succesfully

2.Performing a basic nmap search using nmap facebook.com

The only two ports open are :

• 80 ; used to http
• 443 ; used for https

2.Using a more aggressive nmap search (nmap -A facebook.com)

useful information obtained:

1. facebook.com uses proxygen-bolt

2.Traceroute is obtained

conclusion:

• only ports for http and https are opened
• facebook.com uses proxygen-bolt

Disclamer:

I am still in the early stages of learning pen-testing and am still unable to perform more  sophisticated attacks.
