Vulnerability: This term refers to any flaw, weakness, or gap present in a system’s security framework that can be exploited by a malicious attacker. Such vulnerabilities allow the attacker to gain unauthorized access, disrupt normal operations, or cause significant damage to the system or data. These security weaknesses can exist in software, hardware, or even in procedural controls, making them critical points of concern for maintaining overall system integrity.

Exploit: An exploit refers to a specific technique, method, or piece of software code that is deliberately designed and used to take advantage of a particular vulnerability or weakness within a system, application, or network in order to bypass security measures and gain unauthorized access or control.

Penetration Test (Pen Test): This is a carefully controlled and fully authorized simulated cyberattack designed to thoroughly evaluate the security of a system. Mimicking real-world attack techniques and tactics, it helps identify vulnerabilities and weaknesses in the system’s defenses, providing a comprehensive assessment of how well the system can withstand potential cyber threats.

Threat Model: A threat model is a comprehensive and strategic framework used to systematically identify, analyze, and prioritize the various possible threats that could potentially compromise a system. It takes into account the different attack vectors, vulnerabilities, and associated risks to provide a clear understanding of security challenges and guide the development of effective mitigation strategies.

Black Box Testing: The ethical hacker conducts a thorough examination of the system without any prior knowledge or access to its internal structure, architecture, or source code. This approach effectively simulates the perspective of an external attacker who attempts to find vulnerabilities and weaknesses solely through external interaction and observation.

White Box Testing: The tester is granted complete and unrestricted access to all internal system details, including the source code, system architecture, and detailed design documents. This comprehensive access allows the tester to perform an in-depth security assessment, identifying vulnerabilities that may not be visible through other testing methods.

The Ethical Hacking Process

Professional ethical hackers adhere to a well-defined and systematic process to guarantee comprehensive, effective, and legally compliant security testing.
