Different Types of Hackers 

Hackers are considered a mighty force in the current age of technology, often vicious and capable of great harm but also capable of great good. There are various types of Hackers, each with their own motivations and actions. Understanding these different types is crucial in navigating the complex world of Cybersecurity. Some common types of Hackers are as follows: 
 

Learning about the different categories of Ethical Hackers is vital to understanding different Types of Ethical Hacking practices. Each of these specialised Hacker roles follows their own set of Cyber Security principles and has their specific priorities depending on the nature of their duties. As a result, different hackers are the foundation for the currently existing different Hacking practices.

Different Ethical Hacking practices 

As time has passed, hacking has evolved into different specialisations, with different hackers specialising in these roles. Some of these hacking practices followed by Ethical Hackers are as follows:  

White Box Hacking 

White Box Hacking is also known as Transparent-box Testing or Clear-box Testing. It involves conducting security assessments with full knowledge of the internal workings of the target system. Ethical Hackers in White Box Testing can access detailed information about the system's architecture, source code, network configuration, and other relevant details. This knowledge comprehensively analyses the system's vulnerabilities and potential attack vectors. 

Advantages: With complete system knowledge, Ethical Hackers can conduct in-depth assessments, identify critical vulnerabilities, and provide precise recommendations for remediation. The approach allows for a thorough examination of security controls, ensuring comprehensive coverage. Additionally, White Box Testing facilitates testing for complex scenarios and helps uncover hidden vulnerabilities. 

Disadvantages: The approach assumes access and knowledge that may not reflect real-world conditions, potentially missing vulnerabilities that external attackers could exploit. Furthermore, the extensive system understanding required for White Box Testing can be time-consuming and resource intensive. 

Techniques: White-box Ethical Hackers employ a variety of tools and techniques during their assessments. Common practices include source code review, architecture analysis, and network traffic monitoring. Static analysis tools, debuggers, and vulnerability scanners aid in vulnerability identification.  

Further, it offers a comprehensive and insightful approach to security assessments. With detailed knowledge of the target system, Ethical Hackers can provide valuable insights and recommendations for strengthening security controls and mitigating Cyber Security Risks.

Black Box Hacking 

Black Box Ethical Hacking, also known as External Testing, involves conducting security assessments without prior knowledge of the internal workings of the target system. Ethical Hackers performing Black Box Testing simulate the perspective of an external attacker with limited information. This approach aims to replicate real-world scenarios where attackers have no insider knowledge. 

Advantages: By simulating the perspective of an external attacker, it provides insights into the vulnerabilities that an attacker with no prior knowledge could exploit. This approach helps identify security weaknesses in the system's external-facing components, such as network infrastructure, web applications, and public-facing services. Black Box Testing also helps assess the effectiveness of security controls and incident response mechanisms externally. 

Disadvantages: Black-box Ethical Hacking also has its limitations since Ethical Hackers have limited knowledge of the target system. As a result, they may not uncover vulnerabilities that are only apparent with internal access. Additionally, it may not reveal complex system interactions or vulnerabilities that can only be discovered through internal knowledge. The testing scope is limited to external attack vectors, potentially leaving internal vulnerabilities unexplored. 

Techniques: Black Box Ethical Hacker Interview Questions professionals employ a range of assessment tools and techniques. Commonly used tools include network scanning utilities, vulnerability scanners, and web application testing frameworks. Techniques such as port scanning, fingerprinting, and manual probing are leveraged to detect potential vulnerabilities.

Grey Box Hacking  

Grey Box Ethical Hacking is a hybrid approach that combines White-box and Black-box Testing elements. Ethical Hackers have partial knowledge of the target system in Grey Box Testing, such as access credentials or limited internal information. This approach simulates a scenario where the attacker has some insider knowledge but not complete access to the system. 

Advantages: With partial knowledge of the system, Ethical Hackers can focus on areas more likely to contain vulnerabilities. This approach allows for a more targeted assessment, increasing the efficiency of the testing process. Grey Box Testing balances the depth of analysis offered by White Box Testing and the real-world perspective of Black Box Testing. 

Disadvantages: Grey Box Ethical Hacking also has its limitations. The extent of the partial knowledge can vary, affecting the assessment's scope and effectiveness. Ethical Hackers may miss vulnerabilities that require deeper internal understanding. Additionally, the reliance on partial knowledge introduces the risk of false assumptions or overlooking critical areas that may have been overlooked. 

Techniques: Grey Box Ethical Hackers use assessment tools and techniques to identify potential weaknesses. They may employ vulnerability scanners, network sniffers and web application testing tools. Further, user-based testing, authenticated testing, and privilege escalation are commonly utilised.    

By adopting Grey Box Testing, organisations can gain valuable insights into vulnerabilities that attackers with limited insider knowledge could exploit.

Ethical Hacking: Red Team vs Blue Team 

Red Team vs Blue Team Ethical Hacking is a practice that involves simulating real-world attack and defence scenarios to enhance Cybersecurity. The Red Team represents the offensive side, acting as the simulated attackers. While the blue team takes on the defensive role, protecting the system against the simulated attacks. The objective is to identify vulnerabilities, test security controls, and improve overall resilience.



The Red Team aims to exploit vulnerabilities, breach defences, and gain unauthorised access to the system. They mimic the tactics, techniques, and procedures real attackers use to expose system security posture weaknesses. The Blue Team, on the other hand, focuses on detecting and mitigating attacks. They also monitor the system for suspicious activities and respond effectively to incidents. 

Simulated attack: Red Team members employ various attack techniques during their simulations. This includes Social Engineering, network penetration, vulnerability exploitation, and targeted phishing attempts. They test the system's resilience against different attack vectors to uncover vulnerabilities and weaknesses.  

Defence techniques: The Blue Team uses defensive techniques such as intrusion detection systems, firewalls, security monitoring, incident response procedures, and threat intelligence. 

Further, simulated attack and defence techniques can also involve the use of specialised tools, such as penetration testing frameworks, network scanners, and exploit frameworks. Both teams collaborate to create realistic scenarios that challenge the system's security measures. 

Importance in Cybersecurity: Red Team vs Blue Team Ethical Hacking exercises are crucial in enhancing Cybersecurity. They provide a proactive approach to identifying vulnerabilities and improving defences before real attackers exploit them. By simulating realistic attack scenarios, organisations can uncover weaknesses and assess their incident response capabilities. They can also enhance their overall security posture. 

These exercises foster collaboration between the Red and Blue Teams, promoting knowledge sharing, skill development, and the refinement of defensive strategies. Red Team vs Blue Team engagements also provide valuable feedback on the effectiveness of security controls and incident response procedures. They also assist in examining an organisation's ability to detect and mitigate sophisticated attacks.
