What is Ethical Hacking?
Ethical hacking is gaining unauthorized access to a computer system or network to identify and fix security vulnerabilities. Ethical hackers, also known as white hat hackers, use the same methods and techniques as malicious hackers, but they do so with the permission of the system or network owner. It can be used to improve the security of a system or network by identifying and fixing vulnerabilities before malicious hackers can exploit them. It can also be used to test the effectiveness of a system’s security controls.
Types of Ethical Hackers:
White Hat Hackers:
White hat hackers are individuals who engage in ethical hacking activities with the permission and authorization of system owners. They work to identify vulnerabilities, secure systems, and improve cybersecurity defenses. White hat hackers are often employed by organizations or work as independent consultants.
Black Box Testers:
Black box testers are ethical hackers who simulate an external attacker with no prior knowledge of the target system. They have limited information about the target and attempt to identify vulnerabilities and weaknesses solely through external testing and analysis.
Gray Box Testers:
Gray box testers have partial knowledge of the target system. They possess some information, such as system architecture or user privileges, which helps them in conducting the ethical hacking assessment. Gray box testing combines elements of both black box and white box testing.
Certified Ethical Hackers are professionals who have obtained the Certified Ethical Hacker certification, typically offered by organizations like the EC-Council. They have a broad understanding of various hacking techniques, tools, and methodologies and are skilled in identifying vulnerabilities and securing systems.
Penetration testers, also known as pen-testers, specialize in conducting in-depth assessments of computer systems, networks, or web applications. They attempt to exploit vulnerabilities and gain unauthorized access to evaluate the effectiveness of security controls and identify areas for improvement.
Social engineers focus on exploiting human psychology and manipulating individuals to gain unauthorized access to systems or sensitive information. They use techniques such as phishing, pretexting, or impersonation to deceive people and gather information or gain entry into secure environments.
Bug Bounty Hunters:
Bug bounty hunters are individuals who participate in bug bounty programs offered by organizations. They actively search for vulnerabilities in software, websites, or applications and report them to the organization. In return, they receive rewards or bounties based on the severity and impact of the discovered vulnerabilities.
The Process of Ethical Hacking:
Planning and Reconnaissance:
This initial phase involves understanding the scope of the engagement, identifying the target systems or networks, and gathering relevant information about the target. Reconnaissance techniques may include passive information gathering from public sources, such as search engines, social media, or publicly available databases.
In this phase, the ethical hacker performs active scanning and probing of the target systems or networks to identify open ports, services, and potential vulnerabilities. Network scanning tools and techniques, such as port scanning, vulnerability scanning, or fingerprinting, are employed to gain a deeper understanding of the target’s security posture.
During this step, the ethical hacker tries to gather more specific information about the target’s systems. These include user accounts, network shares, or system configurations. Enumeration techniques may involve querying domain name servers (DNS), performing user enumeration, or extracting information from network services.
In this phase, the ethical hacker systematically identifies and evaluates vulnerabilities present in the target systems or networks. Vulnerability scanning tools, manual testing, and security checklists are utilized to identify weaknesses in software, configurations, or network architecture.
Once vulnerabilities are discovered, the ethical hacker attempts to exploit them to gain unauthorized access or perform specific actions within the system. Exploitation involves leveraging known vulnerabilities or developing custom exploits to test the effectiveness of security controls.
Post-Exploitation and Lateral Movement:
If successful, the ethical hacker may continue to explore the compromised system, escalate privileges, and move laterally within the network. This phase aims to simulate an attacker’s actions after gaining initial access, assessing the potential impact of a breach and the extent of damage that can be inflicted.
Remediation and Follow-up:
The final step involves working closely with the system owner to address the identified vulnerabilities and implement appropriate security measures. The ethical hacker may provide guidance, assist in patching or configuration changes, and offer recommendations to enhance the overall security posture.
