How to Evaluate a Cybersecurity Candidate Beyond the Resume?

In our digital world today where AI modules entered the field of recruitment, it became necessary to evaluate cybersecurity candidates beyond their resume. Undertaking a holistic candidate review may increase the chances of hiring a cybersecurity professional who will contribute to the security poster and team dynamic of the organization.

In this article we will explore cybersecurity recruitment past the qualifications.

Cybersecurity Interview Qs: Problem-solving & Technical Depth 

Interviews allow cybersecurity recruitment to go beyond the bullet points on a resume. Exploring the how behind their accomplishments, understanding their problem-solving approaches, and assessing their critical thinking skills in real-time.
Below are some examples, broken down for easier comprehension.

Problem-Solving & Scenario-Based Questions in Cybersecurity Recruitment

These questions are designed to gauge their real-time thinking, practical knowledge application, and problem-solving methods.

Security Incident Management:

"Describe your process for responding to a suspected ransomware incident on a critical server." (Assesses comprehension of the incident management stages, prioritization skills, containment strategies, eradication methods, recovery procedures, and the ability to derive learning points.)

Immediate Responses:

"Your company's website has been defaced. What are your initial steps for investigation and remediation?" (Assesses immediate actions, evidence gathering, communication, and restoration.)

Vulnerability Management:

"Walk me through your typical vulnerability lifecycle management in a complex organizational setting."
(Assesses understanding of vulnerability scanners, CVSS scoring, patching processes, and exception handling.)

"How would you handle a situation where a critical patch for a widely used software is released, but applying it immediately could cause system instability?" (Evaluates risk-benefit analysis, testing strategies, and communication.)

Hybrid Questions (Combining Problem-Solving and Technical Depth)

In these kinds of questions, cybersecurity recruitment goes beyond theoretical understanding.

By asking candidates to apply their technical skills to practical situations. These questions assess not only what a candidate knows but also how they would apply that knowledge to solve specific security challenges, including their investigative process, tool usage, and understanding of underlying technical principles.

For example: "You've identified unusual network traffic originating from an internal host destined for a known malicious IP address. Describe your process for investigating this activity, including the tools you would use and the technical details you would look for."

Practical cybersecurity challenges for candidate evaluation (pentesting, IR, threat analysis) 

Penetration testing challenges in cybersecurity interviews simulate real-world vulnerability exploitation. They typically involve time-boxed exercises on deliberately vulnerable web or mobile applications, isolated network environments, or CTF-style puzzles. Evaluation focuses on the number and severity of identified vulnerabilities, the methodology employed (reconnaissance, scanning, exploitation), the quality of reporting (including reproduction steps and remediation advice), and the ability to think creatively and chain exploits.

In addition to that, Incident response challenges assess a candidate's ability to handle security incidents effectively. Scenarios include analyzing simulated phishing incidents, investigating anonymized security logs for suspicious activity, performing basic malware analysis, or participating in tabletop exercises discussing response strategies for hypothetical breaches. Evaluation criteria include the ability to identify malicious indicators, understand attack lifecycles, follow proper containment and recovery steps, demonstrate log analysis skills, understand malware behavior, and apply incident response frameworks with strong communication.

While Threat analysis challenges evaluate a candidate's grasp of the threat landscape. These involve analyzing threat intelligence reports to identify actors, TTPs, and potential impact, dissecting known vulnerabilities and exploits, reviewing security architectures to pinpoint weaknesses, and utilizing OSINT techniques to gather relevant information for threat assessment. Evaluation focuses on extracting key information, understanding threat actor motivations, mapping TTPs, assessing risk, and formulating actionable recommendations.

Lastly, Key considerations for implementing these challenges include setting realistic time limits, providing clear instructions, using controlled environments, designing realistic scenarios, focusing on the candidate's process, conducting thorough debriefings, tailoring challenges to the role, and adhering to ethical guidelines. These practical assessments provide a deeper understanding of a candidate's hands-on skills and real-world readiness.

Effective Cybersecurity Reference Checks: 

Skills, ethics, and conduct. The reference checks in cybersecurity recruitment are crucial and should go beyond simply confirming employment dates.  they need to delve into a candidate's skills, ethics, and professional conduct, all of which are paramount in this field.
Here's a concise summary of the provided text on effective cybersecurity reference checks:

Preparing for the Reference Check:

• Choose relevant references: Focus on supervisors, team leads, and project managers who can speak to cybersecurity skills, ethics, and conduct.

• Tailor questions: Align your inquiries with the job description and the candidate's performance in the hiring process.

• Provide context: Briefly explain the cybersecurity role to the reference.

• Maintain professionalism: State the call purpose and duration, and assure confidentiality.

Key Question Areas:

• Skills: Explore technical proficiency with examples, tool proficiency ratings, problem-solving approaches, and how they stay updated.

• Ethics: Inquire about handling sensitive information, adherence to data policies, trustworthiness, and transparency in reporting.

• Conduct: Assess professionalism, work ethic, reliability, teamwork, adherence to policies, response to feedback, and any areas of concern.

During and After the Check:

• Listen actively: Pay attention to tone and examples.

• Take notes: Document key points and concerns.

• Follow up: Seek clarification on red flags.

• Compare feedback: Look for consistency and discrepancies across references.

• Consider the source: Be aware of potential biases.

Red Flags:

• Hesitation, vagueness, inconsistencies, direct negative feedback on ethics/conduct, and reluctance to rehire.

Overall Goal:

Go beyond basic verification to gain valuable insights into a candidate's cybersecurity skills, ethical behavior, and professional conduct to assess their suitability and potential risks. Reference checks are a crucial part of a comprehensive evaluation.

Evaluate Threat Awareness: Scenario-Based Cybersecurity Qs

In cybersecurity recruitment  scenario-based questions are to evaluate a candidate's threat awareness. These questions should assess their ability to identify potential threats, understand their impact, and know how to respond appropriately. For example:

Scenario: "An employee receives an email claiming to be from the IT department, urgently requesting their login credentials to avoid account suspension. The email contains a link that looks slightly different from the company's usual login page. How should the employee, and you as a security professional, respond?"

Evaluation Points 

Recognition of phishing indicators (urgency, mismatched links, unusual sender), proper reporting procedures, employee training awareness, and incident response steps.

The overall goal is to use these practical scenarios to effectively assess a candidate's threat awareness and their ability to apply their knowledge in real-world situations, tailored to the specific role.

Conclusion

In conclusion, effectively evaluating a cybersecurity candidate transcends simply reviewing their resume. By implementing a rigorous assessment procedure that delves beyond the CV, you can gain a far more comprehensive understanding of their capabilities.
