We could stop and prevent hackers by firstly knowing how they hack into our system.

Hacking steps

1. Information Gathering

Target URL /IP address, domain name, physical location, operating system; the more information about target, the more number of attacks hacker can launch. Information gathering included footprinting, port scanning, fingerprinting, banner grabbing and etc.

2. Vulnerability Assessment

This vulnerability means a problem (bug, glitch, or misconfiguration) which allows a system to be attacked or broken into. Vulnerability assessment is process of identifying, quantifying, and prioritizing (or ranking) the vulnerabilities of a system.

3. Search and Build exploit

An exploit is a piece of malicious code which takes advantage of a vulnerability in a software application, usually the operating system, web browser, or web browser’s plug-in.

4. Attack

Launch the attack

5. Maintain Access

After having remote access, they place a root kit or Trojan virus for easier future remote access.

6. Covering tracks

Covering tracks is a process to clean all sign of the hacker by deleting all history logs of target’s system.
