What is Metasploit? [Explained for Beginners]

Metaspoit Framework is a open source penetration tool used for developing and executing exploit code against a remote target machine it, Metasploit frame work has the world's largest database of public, tested exploits. In simple words, Metasploit can be used to test the Vulnerability of computer systems in order to protect them and on the other hand it can also be used to break into remote systems.

Its a powerful tool used for penetration testing. Learning to work with metasploit needs a lot of efforts and time. Ofcourse to can learn metasploit overnight, it needs lots of practice and patience

 Just give a look at following basic steps for beginners to break into a system using metasploit after gathering some information about the target system.

1. Select a right exploit and then set the target.
2.Verify the exploit options to determine whether the target system is vulnerable to the exploit.
3.Select a payload
4.Execute the exploit.

You must be confused !!!!

Now carefully read the following basic terms to get an idea about these four steps mentioned above .I have defined the terms technically and side by side explained in layman language to clarify the things. I have taken an example that an attacker wants to break into a house . I hope my this approach will give you a great idea about these basic terms .

Vulnerability -A weakness which allows an attacker to break into or compromise a system's security.

Like the main gate of house with a weak lock (can be easily opened) , a glass window of house(can be easily broken) etc can be the vulnerabilities in the systems which make it easy for an attacker to break into.

Exploit - Code which allows an attacker to take advantage of a vulnerability system.

The set of different keys which he can try one by one to open the lock , the hammer with him which he can use to break the glass window etc can be the exploits.

Payload- Actual code which runs on the system after exploitation

Now Finally after exploiting the vulnerability and breaking in , he can have different things to do. He can Steal Money destroy the things or just can give a look and come back.. Deciding this is what we mean by setting the Payload.

I hope its enough friends, You will learn more with further tutorials when you will start working with metasploit practically.
