The Five Phases of Ethical Hacking
White hat hacking is also known as ethical hacking. It involves using hacking techniques in order to find and fix weaknesses in computers and networks. To ensure their activities are legal and not harmful to individuals or systems, ethical hackers must follow certain guidelines.
The steps of ethical hacking usually include reconnaissance, scanning, gaining and maintaining access, clearing the tracks, and clearing any traces.
- Reconnaissance is the process of gathering information about the target network or system. To gather as much information about the target as possible, ethical hackers employ a variety of techniques and tools, including searching public records, social media and using specialized software. This information could include information about the system’s hardware or software as well as details about its users and their activities.
- Scanning: Once they have gathered information about the target system and its vulnerabilities, ethical hackers use specialized tools to scan it for potential security holes. Port scanners can be used to identify open ports in the system. Vulnerability scanners search for known flaws in the system’s hardware and software.
- Access: After vulnerabilities are identified, ethical hackers will try to exploit them to gain entry to the system. It may include using various techniques such as password cracking, default passwords or weak passwords, and malware to penetrate the system.
- Access maintenance: After gaining access, ethical hackers might need to keep their access to the system to continue testing for and identifying vulnerabilities. This could include using techniques like creating backdoors and setting up remote access.
- Clearing their tracks: Once they are done with their work, ethical hackers should ensure that there is no trace of their actions on the system. This could include deleting files and tools used by the hackers, as well as resetting passwords and other security measures that they may have modified.
It is important to remember that ethical hackers adhere strictly to guidelines and work closely alongside the owners of the networks and systems they are testing. They are also responsible for reporting any vulnerabilities found and providing recommendations to fix them. This ensures that networks and systems they test are safe from malicious attacks.
