Build challenges that mix developers, defenders, and incident responders so different perspectives are required to solve the problem. Use team-based exercises that reward communication, shared analysis, and coordinated execution rather than individual heroics. The article’s model is closer to purple teaming than solo practice, because many modern security failures are not purely technical. They are coordination failures as well.
Why team-based security challenges work better than solo exercises
The value of a good challenge is not just that it tests whether someone can break or defend something. It should also reveal how well people coordinate under pressure, share partial findings, and make decisions with incomplete information. That is why challenges built around mixed roles usually surface more realistic security behaviour than a single-player lab.
When developers, defenders, and incident responders work the same scenario, each group sees a different slice of the problem. Developers tend to notice design assumptions and deployment shortcuts, defenders notice detection gaps, and responders notice what becomes hard to contain once the issue is live. A challenge that forces those views to intersect teaches collaboration as a security skill, not as a soft add-on.
That collaboration also changes the difficulty profile. A puzzle that one expert can brute-force often becomes much more useful when success depends on interpreting evidence, communicating hypotheses, and sequencing actions across roles. In practice, the exercise starts measuring whether a team can operate as a system, not whether one person can produce the cleverest answer.
How to design challenges that reward coordination, not heroics
The most effective format is a scenario with shared objectives but role-specific clues. Give each participant or subgroup information that is useful on its own, but incomplete without the others. That creates a reason to exchange findings, compare assumptions, and agree on next steps instead of racing to an individual finish line.
Scoring should reinforce that structure. Reward teams for clean communication, clear handoffs, shared documentation, and well-timed escalation. If the scoring only tracks technical completion, participants will optimise for speed and individual output. If it also values explanation quality and coordinated execution, they practice the behaviours that matter during real incidents and complex engineering work.
Good challenge design also uses friction intentionally. Time pressure, noisy evidence, or changing constraints are useful when they force prioritisation and teamwork, but they should not obscure the core lesson. The point is to make participants negotiate uncertainty together, not to hide the solution behind arbitrary difficulty. A well-run exercise leaves room for learning review after the event, where teams can compare how they reached decisions and where collaboration broke down.
For organisations that want a mature pattern, the closest analogue is CISA cyber threat advisories used as source material for scenario building: real-world threat context helps teams practise coordination against believable failure modes rather than abstract puzzles. The same principle applies when teams use structured threat analysis as part of the exercise rather than as an afterthought.
What good looks like after the exercise ends
A successful programme produces more than a score. It leaves behind clearer operating habits: developers better understand what evidence defenders need, defenders better understand implementation constraints, and responders know which pre-incident decisions make containment easier. Over time, the organisation should see fewer silos in incident reviews and more shared language around risk, ownership, and escalation.
It also helps to compare exercises over time. If the same team solves the technical part but still struggles to coordinate, the design is telling you something important about organisational maturity. If teams communicate well but miss the technical flaw, the exercise may need sharper failure conditions or more realistic artefacts. The real measure is whether the exercise exposes both technical and social weaknesses in a way that leads to better behaviour next time.
That is why challenge design should stay close to operational reality. The closer the scenario is to how your teams actually build, monitor, and respond, the more likely it is to reveal useful gaps rather than just reward familiarity with game mechanics.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
CIS Controls v8 and NIST CSF 2.0 set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| CIS Controls v8 | CIS-17 — Incident Response Management | Mixed-role exercises strengthen incident coordination and response readiness. |
| Recommendation — Run team-based exercises that rehearse coordinated incident response across functions. | ||
| NIST CSF 2.0 | RC.RP-01 — Recovery Plan is Executed | Exercises should test coordinated execution under pressure, not individual problem-solving. |
| RS.CO-01 — Personnel know their roles and order of operations during an incident | The question centres on cross-team collaboration and role clarity during security work. | |
| GV.OV-01 — Outcomes of cybersecurity risk management strategy are monitored and reviewed | Challenge design should be measured against whether it improves team collaboration outcomes. | |
| Recommendation — Use scenario exercises to validate coordinated response and recovery execution. Define role-specific responsibilities and communications before running the challenge. Track whether exercises improve coordination outcomes, not just technical completion. | ||
| ISO/IEC 27001:2022 | A.5.24 — Information security incident management planning and preparation | Team-based exercises are a preparation mechanism for coordinated security response. |
| Recommendation — Use exercises to validate incident management planning, roles, and handoffs. | ||
Practitioner Guidance
What to prioritise: Start by defining the collaboration behaviour you want to see, then build the technical problem around it. If the exercise does not require participants to exchange information across roles, it is probably not testing teamwork.
What to verify: Make sure the scoring rubric values communication quality, shared reasoning, and coordinated action. Otherwise, participants will learn that speed matters more than cooperation.
Common mistake: Turning the challenge into a puzzle for the strongest individual contributor. That approach can produce a winner, but it will not tell you whether the wider team can handle a real security event.
Practitioner takeaway: The best challenge is one where technical success depends on the team making better decisions together, because that is the capability most organisations actually need under pressure.
