Essential Work Samples for Evaluating AI-Augmented Cybersecurity Defense Skills

As cyber threats grow in sophistication and volume, organizations are increasingly turning to artificial intelligence to enhance their security posture. AI-augmented cybersecurity defense represents the cutting edge of this field, combining traditional security expertise with advanced machine learning capabilities to detect, analyze, and respond to threats more effectively than ever before.

Identifying professionals who truly understand how to leverage AI in cybersecurity contexts presents a unique challenge. While many candidates may list AI and cybersecurity skills on their resumes, determining who can effectively apply these technologies in real-world scenarios requires more than a standard interview process. This is where carefully designed work samples become invaluable.

Work samples for AI-augmented cybersecurity roles should evaluate not only technical proficiency with AI tools and cybersecurity principles but also critical thinking, problem-solving abilities, and the capacity to communicate complex technical concepts clearly. The ideal candidate must demonstrate an understanding of both cybersecurity fundamentals and how AI can enhance these capabilities.

The following work samples are designed to evaluate candidates' abilities to implement, evaluate, and strategize with AI-augmented cybersecurity tools. Each exercise simulates real-world scenarios that professionals in this field would encounter, providing a window into how candidates approach complex security challenges with AI-enhanced solutions.

By incorporating these exercises into your hiring process, you'll gain deeper insights into candidates' practical skills and thought processes, helping you identify those who can truly strengthen your organization's security posture through the effective application of AI technologies.

Activity #1: AI-Enhanced Threat Detection Simulation

This exercise evaluates a candidate's ability to use AI tools to detect and analyze potential security threats in a network environment. It tests their understanding of both cybersecurity principles and how AI can enhance threat detection capabilities. Candidates will need to demonstrate their ability to interpret AI-generated alerts, distinguish between false positives and genuine threats, and recommend appropriate responses.

Directions for the Company:

• Prepare a dataset of network traffic logs that include both normal activity and simulated attack patterns (e.g., data exfiltration attempts, unusual login patterns, potential malware communication).
• Provide access to an AI-based security analytics platform or tool (e.g., a simplified version of Darktrace, CrowdStrike, or an open-source alternative like AI-Hunter).
• Create a scenario brief that explains the fictional company's environment, security concerns, and the specific task.
• Allocate 60-90 minutes for this exercise.
• Have a cybersecurity expert available to evaluate the candidate's approach and conclusions.

Directions for the Candidate:

• Review the provided network traffic dataset using the AI security tool.
• Identify potential security threats flagged by the AI system.
• Analyze each alert to determine:
• Whether it's a genuine security concern or a false positive
• The nature and severity of any confirmed threats
• What additional information would be helpful for investigation
• Prepare a brief report (15 minutes) explaining your findings, including:
• Which threats you identified and why they're concerning
• How you distinguished between false positives and genuine threats
• Your recommended response actions prioritized by urgency
• How you would improve the AI detection capabilities based on your analysis

Feedback Mechanism:

• After the candidate presents their findings, provide feedback on one aspect they handled well (e.g., thorough analysis of a particular threat, effective prioritization) and one area for improvement (e.g., missed a subtle attack pattern, overreliance on AI without human verification).
• Give the candidate 10-15 minutes to revisit their analysis based on the feedback and explain how they would adjust their approach or conclusions.
• Observe how receptive they are to feedback and their ability to quickly incorporate new perspectives into their analysis.

Activity #2: AI Security Tool Evaluation and Implementation Planning

This exercise assesses a candidate's ability to strategically evaluate AI-based security tools and plan their implementation within an organization's security infrastructure. It tests their understanding of both the technical capabilities of AI security solutions and the organizational considerations necessary for successful deployment.

• Ask the candidate to spend 10 minutes revising one section of their implementation plan based on the feedback.
• Evaluate their ability to adapt their strategy while maintaining a coherent overall approach.

Activity #3: AI-Augmented Security Incident Response Simulation

This exercise evaluates a candidate's ability to leverage AI tools during an active security incident. It tests their incident response skills, critical thinking under pressure, and ability to effectively use AI-enhanced security tools to investigate and contain a breach while minimizing damage.

Directions for the Company:

• Evaluate their technical knowledge of AI security concerns and their ability to translate that knowledge into practical security measures.

Frequently Asked Questions

How technical should these exercises be for different seniority levels?

For junior roles, focus more on the candidate's understanding of basic principles and their ability to use AI-augmented tools effectively. For senior roles, increase the complexity of scenarios and place more emphasis on strategic thinking, architectural decisions, and the ability to identify subtle security issues that might affect AI systems.

What if we don't have access to sophisticated AI security tools for the exercises?

You can use open-source alternatives or demo versions of commercial tools. For some exercises, you can also create simplified simulations or provide screenshots and sample outputs from these tools rather than requiring direct interaction with them. The key is testing the candidate's approach and reasoning, not their familiarity with specific tool interfaces.

How can we evaluate candidates who have strong cybersecurity backgrounds but limited AI experience?

Focus on their ability to apply security principles to AI contexts and their willingness to learn. Look for transferable skills like threat modeling, risk assessment, and incident response fundamentals. Consider including a learning component in the exercise where they need to quickly understand a new AI security concept and apply it.

Should we expect candidates to have coding skills for these exercises?

It depends on the specific role requirements. For positions that involve developing or modifying AI security tools, include a coding component. For roles focused on implementation and operation of existing tools, focus more on configuration, analysis, and strategic application rather than coding from scratch.

How do we account for the time constraints of the interview process with these in-depth exercises?

Consider having candidates complete some preparation work before the interview (like reviewing documentation or preparing initial analyses). You can also focus each exercise on a specific phase or aspect of the work rather than expecting a comprehensive solution. The goal is to see their approach and thought process, not necessarily a complete implementation.

What if a candidate identifies different vulnerabilities or recommends different solutions than we anticipated?

This can actually be valuable! If their analysis is sound and their recommendations are reasonable, it may indicate creative thinking and a fresh perspective. Evaluate the quality of their reasoning and the effectiveness of their proposed solutions rather than expecting them to match a predetermined "correct" answer.

AI-augmented cybersecurity defense is a rapidly evolving field that requires professionals who can blend traditional security expertise with an understanding of advanced AI capabilities. By incorporating these practical work samples into your hiring process, you'll be better equipped to identify candidates who can truly enhance your organization's security posture through the effective application of AI technologies.
