MAIN STEPS
A security pentest typically involves the following steps:
- Planning and reconnaissance: This involves gathering information about the target system or network, including IP addresses, network topology, operating systems, software versions, and any other relevant information.
- Scanning: This step involves using automated tools to scan the target system or network for open ports, vulnerabilities, and other weaknesses that could be exploited.
- Exploitation: Once vulnerabilities have been identified, the penetration tester attempts to exploit them to gain unauthorized access to the system or network. This may involve using tools such as Metasploit or manually crafting exploit code.
- Post-exploitation: After gaining access, the penetration tester may attempt to escalate privileges, install backdoors or rootkits, or exfiltrate sensitive data.
- Reporting: Finally, the penetration tester produces a detailed report outlining the vulnerabilities that were identified, the methods used to exploit them, and recommendations for mitigating the identified risks.

Penetration testing is an essential part of any comprehensive security program, as it can help organizations identify and address security weaknesses before they can be exploited by malicious attackers. However, it is important to note that penetration testing should only be conducted with the explicit permission of the target organization and should be performed by experienced and qualified professionals.
THE TARGET
The main target of penetration testing is to identify security vulnerabilities in a computer system, network, or application that could be exploited by attackers. By simulating an attack, penetration testing helps organizations identify weaknesses and assess the effectiveness of their security controls. This allows them to prioritize and allocate resources to address vulnerabilities, improve their overall security posture, and reduce the risk of a successful attack.
