There are four types of protocols IP, UDP, TCP, ICMP and these are the protocols that are used by Nmap to perform scans on any target.

IP – Internet Protocol

TCP – Transmission Control Protocol

UDP – User Datagram Protocol

ICMP – Internet Control Message Protocol

What is a Protocol?

We are talking about protocols and about some heck around here but before we proceed let’s discuss what actually protocol is?

Hi! Nmap is the most powerful tool to check the security level of your website so in this post, I am going to say how to perform it.

There are several scan techniques to know about the server but the plain scan gives you the ports. A plain scan can be filtered by the firewall so every website ports cannot be detected.

Open cmd in windows or terminal in Linux

What is TCP/IP and how it works?

TCP stands for Transmission Control Protocol. If you want what is protocol you can read this tutorial, networking protocols with Nmap. I already said to you that it is the most used protocol on the net and if you want to know why it is used that much heavily continue to read. Another point is TCP is also called an Internet protocol and TCP/IP.

Here now I am on the best topic on how to change the MAC address (Media Access Control). Yeah! Your MAC address can be spoofed.

There are many ways to change the MAC address which I will show them in my later posts but now in this tutorial, I am going to use a utility named TMAC which lets you change.

TMAC stands for Technitium MAC Address Changer. Click here to download it. Once after installing if you ran that software you can find different adapters or network cards you are using and thereafter selecting the card you can enter your own customized address or you can select from the preloaded profiles.

Hello Everybody! This is article again on techsoftcenter to discuss worms, some creepy worms in computers. In my previous post, I have already discussed the virus, top 10 hacks, iloveyou virus, and its source code.

What is a worm?

The worm is an animal which moves very slowly and this is according to science. In computers, the worm is something which makes the computer slow by replicating itself. Maximum worms won’t do any harm but they will replicate themselves and captures free space.
