Key Pre-Screening Questions to Ask Ethical Hacker in an Interview

What is the definition of ethical hacking?

Ethical hacking, also known as penetration testing, is a legalized and systematic process of probing and finding security vulnerabilities in an IT infrastructure. The main goal is to identify and fix these vulnerabilities before malicious hackers can exploit them, enhancing the overall system security.

Why do you want to become an ethical hacker?

The realm of ethical hacking is both challenging and rewarding. As an ethical hacker, you get the thrill of breaking into complex systems without the legal implications. It offers a way to use technical prowess to make systems safer and more efficient, contributing positively to the digital world.

Can you give us an example of a project where you successfully identified a security vulnerability?

In a past project, we discovered a significant weakness in the client's web application firewall through penetration testing. This allowed us to recommend necessary countermeasures to bolster the application's security. Essentially, the process was a blend of technical proficiency, strategic thinking, and solution-oriented mindset.

Tell us about a time you failed to identify a security vulnerability and how you rectified it

In one of the early stages of my career, I overlooked a minor vulnerability during a routine security audit. Although that vulnerability was exploited, we were quick to respond, patch the system, and reconfigure our security protocols to prevent future breaches. It significantly stressed the importance of thoroughness in our line of work.

What certifications in ethical hacking do you hold?

Certifications play a crucial role in validating an ethical hacker’s skills. Some popular ones include Certified Ethical Hacker (CEH), Certified Information Systems Security Professional (CISSP), and Offensive Security Certified Professional (OSCP).

Which coding languages are you proficient in and how have you utilized them in your past role as an ethical hacker?

Languages like Python, SQL, JavaScript, C++, and Bash are often used in ethical hacking for various tasks. These include creating scripts, exploiting vulnerabilities, manipulating databases, or detecting system weaknesses. Proficiency in these languages can vastly augment an ethical hacker's toolkit.

How do you keep up-to-date on the latest hacking techniques and cybersecurity developments?

Staying current in the dynamic field of cybersecurity requires habitual reading of industry-related news, attending conferences, participating in hacking forums, and enrolling in continuous education programs. This active learning approach helps hone skills and remain effective as an ethical hacker.

Do you have experience in penetration testing?

Penetration testing is a key aspect of ethical hacking, where one intentionally exploits systems to identify vulnerabilities. Acquired practical experience in this field translates into the ability to assess and enhance an organization's cyber defense mechanisms effectively.

How comfortable are you in operating both Windows and Linux environments?

Dexterity in both Windows and Linux environments is crucial for an ethical hacker, as many systems and servers operate on these platforms. Comfortability with these operating systems allows for effective auditing and probing to identify weaknesses that could potentially be exploited.

Can you explain social engineering and how it is related to ethical hacking?

Social engineering is a non-technical strategy used by hackers to manipulate individuals into revealing confidential information. Ethical hackers need to understand this approach to identify such vulnerabilities in human systems, offering training and strategies to combat such tactics.

Describe a time when you had to apply critical thinking skills to solve a problem in a past role

Critical thinking skills are crucial in ethical hacking. For example, during an internal security audit, finding an unexplained increase in data usage required a well-thought-out investigation to trace it back to a third-party application, eliminating potential security threats.

Do you have experience in identifying vulnerabilities in network systems?

Identifying network system vulnerabilities is a primary duty of an ethical hacker. These vulnerabilities could range from insecure data transmission to weak access controls. Realizing such weaknesses allows for corrective measures to be implemented and systems security to be enhanced.

Which security tools are you most proficient at using?

Security tools like Wireshark for network protocol analysis, Metasploit for penetration testing, and Burp suite for web application security testing are essential for ethical hacking. Proficiency in these tools enables more effective and efficient identification and mitigation of vulnerabilities.

What strategies do you use to handle stress when working under tight deadlines?

Working under tight deadlines can be stressful but essential in the cybersecurity world. Effective strategies to mitigate this stress include prioritizing tasks, breaking down larger tasks into manageable bits, and ensuring adequate rest, all contributing to sustained productivity.

Could you explain a time when you needed to convey a complex hacking concept to non-technical team members?

Communicating complex concepts to non-technical individuals poses its own challenges. The key is to break down complex information into easily digestible parts, using metaphors and real-life examples to illustrate key concepts effectively.

Do you have experience working with security policies and disaster recovery plans?

Working with security policies and disaster recovery plans is a vital part of maintaining and enhancing cybersecurity efforts. These guidelines and procedures help dictate the organization's approach to potential threats and tackling data breaches, enhancing overall resiliency.

How experienced are you in cloud computing and related security measures?

With the shift towards cloud services, understanding the security measures related to cloud computing has become increasingly important. This includes knowledge of data encryption, network security, and understanding specific vulnerabilities related to the cloud.

Do you have knowledge in securing databases and protecting sensitive data?

Securing databases and sensitive data is of utmost importance in the current information age. An ethical hacker should know how to encrypt sensitive data, manage user privileges, understand SQL injection, and secure database from common vulnerabilities.

Could you describe the most challenging project you've worked on and what you learnt from it?

The most challenging projects often yield the most important lessons. Whether this was a particularly complex system vulnerability or a security breach requiring a prompt response, each challenge faced and overcome adds more tools to an ethical hacker's toolkit.

What makes a good ethical hacker in your opinion?

A good ethical hacker, in my opinion, has a strong technical skillset, problem-solving abilities, and outstanding ethical standards. They should also be dedicated to continual learning, as the cybersecurity landscape rapidly evolves.
