I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

Penetration testing, also known as ethical hacking, involves assessing the security of a system or network by simulating real-world attacks. Penetration testers use a variety of techniques to identify vulnerabilities and potential entry points that malicious actors could exploit. Here are some common techniques used in penetration testing:

  1. Reconnaissance: This technique involves gathering information about the target system or network using publicly available sources, such as search engines, social media, or WHOIS databases. It helps identify potential vulnerabilities, weak points, and possible attack vectors.
  2. Scanning and Enumeration: Penetration testers use automated scanning tools to identify open ports, services, and system configurations. They also perform enumeration to gather detailed information about the target, such as user accounts, network shares, or directory structures.
  3. Vulnerability Assessment: Penetration testers conduct vulnerability scans using specialized tools to identify known vulnerabilities in the target system or network. These scans help discover weaknesses that could be exploited by attackers, such as outdated software, misconfigurations, or insecure coding practices.
  4. Exploitation: Once vulnerabilities are identified, penetration testers attempt to exploit them to gain unauthorized access or escalate privileges. They may use techniques like SQL injection, cross-site scripting (XSS), remote code execution, or buffer overflows to exploit weaknesses in software or system configurations.
  5. Password Cracking: Penetration testers employ password cracking tools to test the strength of user passwords. They use techniques like brute-forcing, dictionary attacks, or rainbow table attacks to identify weak or easily guessable passwords.
  6. Social Engineering: Social engineering techniques involve manipulating individuals to divulge sensitive information or perform actions that compromise security. Penetration testers may use phishing emails, phone calls, or impersonation to assess the susceptibility of employees to social engineering attacks.
  7. Post-Exploitation: Once access is gained, penetration testers perform post-exploitation activities to assess the impact of a successful attack. This includes escalating privileges, pivoting to other systems, exfiltrating data, or maintaining persistence in the target environment.
  8. Reporting: Penetration testers document their findings, including the vulnerabilities discovered, the techniques used, and the impact of successful exploits. They provide detailed reports with recommendations for remediation and improving the overall security posture.

It's important to note that penetration testing should be conducted within a controlled and authorized environment to avoid any negative impact on production systems. Organizations should engage skilled and experienced professionals or penetration testing teams to ensure comprehensive and effective testing while minimizing risks.
