1. Understanding the Ethical Hacker Landscape
The cybersecurity world has evolved beyond the simple “white hat vs. black hat” dichotomy. While black hat hackers remain malicious actors, the “good guys” now encompass a spectrum of roles, including red teams, blue teams, purple teams, ethical hackers, and penetration testers. It is crucial to understand the function of ethical hacking and how to perform security assessments, threat modeling, and VTAs.
- Red Teams: Offensive security specialists who simulate attacks to identify vulnerabilities.
- Blue Teams: Defensive security specialists responsible for protecting systems and responding to incidents.
- Purple Teams: Teams that combine red and blue team functions, fostering collaboration and knowledge sharing.
- Ethical Hackers: Security professionals who use their hacking skills for defensive purposes, with permission from the system owners.
- Penetration Testers (Pentesters): A type of ethical hacker who focuses on finding and exploiting vulnerabilities in systems and applications.
Ethical hacking involves thinking like an attacker to uncover weaknesses that malicious actors could exploit. This proactive approach allows defensive teams to implement patches and strengthen security before a real attack occurs. This is done through controlled simulated cyberattacks. While perimeter penetration vulnerabilities are often tested, ethical hackers also explore deeper weaknesses within networks and applications, such as data exfiltration vulnerabilities.
2. The Diverse Roles of Ethical Hackers
Ethical hackers can work in various settings, each with its own unique focus and responsibilities.
- Freelance Consultants: Independent professionals who offer their ethical hacking services to various clients.
- Consulting Firm Employees: Employed by firms that specialize in offensive cybersecurity services.
- In-House Employees: Dedicated to protecting a specific company’s websites, applications, and networks.
While all ethical hackers need a firm understanding of current attack methods and tools, in-house ethical hackers often require in-depth knowledge of their organization’s specific systems and software.
One advantage of having an in-house red team is their intimate understanding of the organization’s infrastructure. This insider knowledge allows them to identify vulnerabilities that external consultants might miss. However, in-house teams must avoid becoming too narrowly focused, as external consultants can bring fresh perspectives and uncover overlooked weaknesses.
It is essential to seek written authorization before conducting any offensive activities. This permission must specify the systems, networks, applications, and websites included in the simulation attack. Expanding the service’s scope without explicit written authorization is strictly prohibited.
Engagements can be categorized as white-box, black-box, or gray-box, depending on the level of information provided to the ethical hacker:
- White-Box Engagement: The ethical hacker receives comprehensive information about the target system, allowing for a thorough and rapid vulnerability assessment.
- Black-Box Engagement: The ethical hacker receives no insider information, simulating a real-world attack scenario and providing insights into potential attack vectors.
- Gray-Box Engagement: The ethical hacker has some knowledge of the system, representing a scenario where an attacker has already gained some access.
Many organizations use a combination of these approaches, involving both in-house and external ethical hackers. This multifaceted strategy provides a thorough evaluation of the organization’s defenses.
Ethical hacking skills are valuable in other cybersecurity roles. Network security analysts and engineers, purple teams, application security developers, and security researchers (bug hunters) all benefit from a solid understanding of offensive techniques.
3. Essential Skills for Aspiring Ethical Hackers
While stories abound of black hat hackers converting to white hats, ethics are paramount to becoming a successful ethical hacker.
Ethical hackers must possess a strong moral compass and unwavering commitment to doing the right thing, regardless of potential temptations. A history of cybercrime is unacceptable for a cybersecurity team member. When seeking work as an ethical hacker, a resume including unauthorized or unethical behavior is a disqualifier. Developing a set of ethical life-guiding standards is more involved than desiring a career change.
Beyond ethics, strong technical skills are critical. Ethical hackers must be able to demonstrate advanced cybersecurity technical skills and recommend effective mitigation and remediation strategies.
Key technical skills include:
- Networking: Understanding of wired and wireless networks, protocols, and security concepts.
- Operating Systems: Proficiency with Windows and Linux, including file systems, permissions, and security configurations.
- Security Technologies: Knowledge of firewalls, intrusion detection/prevention systems, and other security tools.
- Coding: Strong coding skills in languages like Python, C++, and Java for developing and modifying exploits.
- Attack Methods: Deep understanding of manual, hands-on attack methods and techniques.
- Analytical Thinking: The ability to think like an adversary and anticipate their moves.
- Creative Thinking: Ethical hackers need to understand the value of data and systems.
An ethical hacker should have defended enough assets to anticipate the adversary’s moves. Above ethics and technical skills, creative and analytical thinking is important.
4. Ethical Hacking Certifications and Education
Obtaining relevant certifications and a solid education is crucial for establishing credibility and demonstrating expertise in ethical hacking.
4.1. Key Certifications
- Certified Ethical Hacker (CEH): Offered by EC-Council, the CEH certification validates an individual’s knowledge of ethical hacking techniques and tools. According to EC-Council, “A Certified Ethical Hacker is a skilled professional who understands and knows how to look for weaknesses and vulnerabilities in target systems and uses the same knowledge and tools as a malicious hacker, but lawfully and legitimately to assess the security posture of a target system(s). The CEH credential certifies individuals in the specific network security discipline of Ethical Hacking from a vendor-neutral perspective.”
- Offensive Security Certified Professional (OSCP): Offered by Offensive Security, the OSCP certification is a hands-on, technically challenging certification that requires candidates to demonstrate their ability to penetrate systems and networks. According to Offensive Security, “The OSCP examination consists of a virtual network containing targets of varying configurations and operating systems. At the start of the exam, the student receives the exam and connectivity instructions for an isolated exam network that they have no prior knowledge of or exposure to. The successful examinee will demonstrate their ability to research the network (information gathering), identify any vulnerabilities, and successfully execute attacks. This often includes modifying exploit code with the goal of compromising the systems and gaining administrative access. The candidate is expected to submit a comprehensive penetration test report, containing in-depth notes and screenshots detailing their findings. Points are awarded for each compromised host, based on their difficulty and level of access obtained.”
Earning other cybersecurity certifications offered by the EC-Council can also enhance your employability as an ethical hacker.
4.2. Formal Education
A bachelor’s degree in a computer-related field is a solid foundation for a career in ethical hacking. Computer science or network engineering programs provide the necessary technical background. When choosing a cybersecurity bachelor’s program, prioritize those with a strong interdisciplinary focus. Good programs emphasize computer engineering, computer science, and business management skills. Look for courses in technical writing and legal issues surrounding technology and ethics. The best cybersecurity professionals are well-rounded individuals with a broad perspective.
4.3. Continuous Learning
Even with a degree and certifications, continuous self-study is essential for staying current with the latest attack methods and offensive strategies. A home lab is a valuable tool for practicing and experimenting with different techniques. YouTube videos, internet groups and forums, and social media posts and exchanges are all used by successful ethical hackers to maintain their competitive edge.

6. Typical Ethical Hacking Assignments
Ethical hackers perform various tasks, including threat modeling, security assessments, vulnerability threat assessments (VTA), and report writing. The specific responsibilities vary from company to company, but these core functions are typically included in the job description.
6.1. Threat Modeling
Threat modeling is a process used to optimize network security by identifying vulnerabilities and determining countermeasures to prevent or mitigate attacks. A threat can be malicious (such as a denial-of-service attack) or incidental (such as hardware failure).
The ethical hacker provides a comprehensive view of potential malicious attacks and their consequences for the organization.
The objective of effective threat modeling is to determine where to focus efforts to keep a system secure. This is an iterative process that consists of:
- Defining assets.
- Recognizing what each application does with these assets.
- Creating a security profile for each application.
- Identifying potential threats.
- Prioritizing potential threats.
- Documenting adverse events and the actions taken in each case.
The ethical hacker’s role is crucial in ensuring that threat modeling remains a proactive exercise rather than a post-mortem analysis after an actual attack.
6.2. Security Assessment
An ethical hacker, whether a pentester or red team leader, is often assigned to provide a security assessment. A security assessment measures the security posture of a system or enterprise based on risk.
Security assessments are periodic exercises that test an organization’s security preparedness. They include checks for vulnerabilities related to IT systems and business processes and recommend steps to lower the risk of future attacks.
Security assessments help determine how well security-related policies are adhered to. They can identify the need for additional or enhanced security training.
The culmination of a security assessment is a report that identifies weaknesses and makes recommendations, making it an invaluable risk management tool.
6.3. Vulnerability Threat Assessment
A vulnerability threat assessment (VTA) is a process used to identify, quantify, and rank vulnerabilities relevant to a system, along with the threats that could exploit those vulnerabilities. While closely related to a security assessment, the VTA is conducted to identify and correlate specific threats and vulnerabilities.
The basic security assessment identifies vulnerabilities and evaluates the security posture of the enterprise independent of any specific threat. The VTA is a more threat-based assessment.
Systems for which VTAs should be performed include:
- Information technology systems
- Energy supply systems
- Water supply systems
- Transportation systems
- Communication systems
VTAs can be conducted for various organizations, from small businesses to large regional or national infrastructure entities. Each of these system types requires someone in an ethical hacker role to perform the VTA.
6.4. Report Writing
The ability to write clear and concise professional reports is critical for ethical hackers. Gathering data, identifying vulnerabilities, and correlating threats are of little value if the information cannot be effectively communicated to risk management leaders.
Reports from the red team often drive significant security resource expenditures. Risk management professionals need complete confidence in the ethical hackers’ findings.
In some cases, an ethical hacker is an outside consultant retained by a firm to provide the information needed to justify security expenditures for upper management or the board of directors. In the world of security consulting, the report is the primary deliverable and is of the utmost importance.
When considering professional certifications and educational opportunities to elevate a career to include ethical hacking, do not underestimate business writing expertise.
The ability to produce a well-written report will boost an individual’s career over an otherwise equally qualified peer.
| Assignment | Description | Deliverables |
|---|---|---|
| Threat Modeling | Identifying potential threats and vulnerabilities in a system, application, or network. | Documentation of potential threats, vulnerabilities, and recommended countermeasures. |
| Security Assessment | Evaluating the security posture of a system or enterprise. | Report identifying weaknesses and making recommendations for improvement. |
| Vulnerability Threat Assessment | Identifying, quantifying, and ranking vulnerabilities relevant to a system, along with the threats that could exploit them. | Report identifying specific threats and vulnerabilities and recommending remediation measures. |
| Report Writing | Communicating findings and recommendations to risk management leaders. | Clear, concise, and professional reports that accurately convey the results of the assessment and provide actionable recommendations. |
7. The Essence of Ethical Hacking
Being a member of an in-house red team or working as a freelance white hat hacker is an exciting vocation. They are highly sought-after positions that can engender respect and prestige within the cybersecurity community.
Ethical hacker jobs are necessary for effectively protecting networks, systems, and applications. This expertise is required throughout national infrastructure entities and secures critical or sensitive data across all industries.
For many, the term “ethical hacker” seems like an oxymoron, combining high ethical standards with the notion of “hacking,” usually associated with nefarious activity. An “offensive security professional” may be a better description, but “ethical hacker” is often used because it sounds more mysterious.
Regardless of the job title, these positions are not for the morally questionable or anyone with a history of being a bad actor. Ethical hackers are necessarily privy to sensitive information, the divulging of which could be catastrophic for the enterprise.
A security clearance is often required for government employees and contractors. Obtaining a security clearance includes a background investigation and an examination of financial and social media data.
With the rare exception of the independent freelance offensive cybersecurity consultant, ethical hackers normally work as part of a team. If on a red team, the other team members will be like-skilled ethical hackers or pen-testers, and the team will be part of the overall security department.
In a smaller organization, the ethical hacker may be the only person with an offensive role but will invariably be part of a larger security team. The ability to work well with other team members and to communicate effectively is critical to success.
An ethical hacker is not the stereotypical hoodie-wearing young person working out of his parents’ basement, who decided to trade their black hat in for a white one. She is more often an educated, experienced, skilled, and articulate professional dedicated to making the world a safer place to live and work.
While history may provide examples of self-taught individualists rising to the pinnacle of cybersecurity ops, an education with a minimum of a bachelor’s degree, combined with one or more specialized professional certifications, is the standard for ethical hackers.
Years of mettle-proving experience in software development and/or more traditional defensive security roles are not at all unusual for successful ethical hackers.
