Types of Cyber Security Exercises: A Comprehensive Guide

Not investing in improving your cybersecurity capabilities as an organization can have serious consequences. According to Sophos's State of Ransomware 2025, the median ransom payment reached $1 million, and victims spent an average of $1.53 million recovering from an attack — on top of any ransom paid.

So, what are the solutions that can help you avoid this kind of substantial loss?

Well, first of all, you should ensure your team's cyber preparedness and give them the training and resources they need to face potential cyber threats and attacks.

You can do this by utilizing different types of cybersecurity exercises, which can help you play out realistic scenarios and increase your overall security posture.

This article will give an in-depth overview of different types of cybersecurity exercises and their benefits, as well as real-life examples of organizations that successfully trained their teams through these activities.

What Is a Cyber Security Exercise?

Simply put, a cybersecurity exercise is a practical way for an organization to boost its cyber resilience and prepare the team for a potential cyber threat or attack.

This is achieved through different cybersecurity drills and exercises on a cyber range, which is a platform that enables simulated environments for training and testing a team's incident response capabilities.

Cyber range technology typically includes a simulated network infrastructure, systems, and tools, which help participants play out realistic scenarios and understand what it really feels like to be under a cyberattack.

Enterprises globally use cyber range technology to:

· Assess their cyber readiness through realistic scenarios

· Improve their team's collaboration skills in a simulated environment

· Identify and address their cyber skills-development needs

· Measure how effective their cyber training efforts are

What Types of Cyber Security Exercises Are There?

When it comes to improving your organization's security posture, there is no one-size-fits-all approach to running cybersecurity exercises. Organizations need a clear understanding of their security needs, and they must choose the exercise that best suits their needs.

The table below compares the most common formats at a glance; the sections that follow explain the flagship formats in depth, and a final section summarises the other formats worth knowing.

Live Fire Exercise

A live-fire cybersecurity exercise is designed to help professionals simulate and practise defending against real-world cyber threats and attacks.It allows the whole team to come together and practise their technical skills in responding to cyberattacks in a rapid, effective manner.

With its deep technical red team vs blue team elements, the primary objective of live-fire training is to give participants as realistic an experience as possible — a taste of what defending IT systems under intense cyberattacks looks like. Predefined scenarios are specifically designed to allow scoring, benchmarking, and effective data capture, and a standardised game-net environment allows fair scoring while remaining manageable for the blue team.

The most significant learning objectives for the live-fire exercise are:

· Encouraging cooperation between different stakeholders in the organization's cyber defence.

· Actively monitoring and properly analysing a cyberattack.

· Rehearsing essential defensive measures against an attack on a particular field, or a combination of fields.

· Practising stress handling and decision-making among several difficult or competing options.

· Providing reports and creating an accurate basis for management.

The Process Behind the Live Fire Exercise

The success of this activity is all about team effort, and every member should contribute. A typical live-fire exercise on a cyber range runs in three phases:

· Planning and preparation: Participants identify the main objectives, define the scope, and study the environment, then divide roles and responsibilities and understand their focus areas.

· Deployment and execution: The defending team starts protecting its environment against attacks from the red team and executes the response plan they have practised.

· Evaluation and debriefing: Participants take part in an evaluation session where they get an assessment of their performance, identify areas for improvement, and develop an action plan to fix the vulnerabilities in their existing response plan.

Benefits of the Live Fire Exercise

A key benefit of boosting your team's cyber resilience through a live-fire exercise comes down to the realistic experience it provides.It closely simulates real-world threats and challenges, making it an ideal environment for the team to learn how to react and to evaluate their capabilities under realistic pressure.

That realism helps teams sharpen their defences and understand how to identify and mitigate cyber threats effectively. It is important for organizations to uncover the gaps and vulnerabilities in their existing security posture and improve them to meet current requirements. Additionally, participants get immediate feedback on their performance, giving them valuable insight into their decisions, actions, and problem-solving.

Threat Hunting Exercise

A threat-hunting cybersecurity exercise is an activity where a team of experts works together in a simulated environment with one clear goal — to find and stop threats through a collaborative effort.

Imagine detectives searching for clues at a crime scene. Here, the cybersecurity professionals are looking for clues and evidence of suspicious activity, from computer viruses to attackers attempting to steal information.

When it comes to practising a team's cybersecurity skills, a threat-hunting exercise is an effective solution. It teaches participants how to collaborate and use different tools to hunt for potential threats, and it pushes them to make accurate decisions in a timely manner.Most importantly, it improves the team's ability to respond to growing volumes of threats and to stay proactive when there is a risk of attack.

The Process Behind the Threat Hunting Exercise

The threat-hunting exercise generally consists of six layers that are fundamental to a successful outcome:

· Planning: Define the objectives, scope, and timeline of the activity.

· Preparation: Set up the network, systems, and applications that will be used throughout the exercise.

· Execution: Participants actively search for signs and analyse system logs to identify potential threats.

· Response: After identifying a threat, the team takes action to mitigate it — typically by isolating systems or blocking malicious traffic.

· Analysis: The team analyses the collected data to identify patterns and trends and to understand weaknesses within the network.

· Reporting: Report the results to stakeholders, including a summary, the actions taken, and recommendations for future improvements to the security posture.

For a more in-depth overview of the threat-hunting exercise, have a look at this article on our blog.

Benefits of the Threat Hunting Exercise

Running a threat-hunting exercise can be extremely beneficial for any organization that needs to boost its cyber preparedness and improve its security posture. It builds the proactive detection skills that separate teams who wait for alerts from teams who go looking for threats before they cause damage.

Capture the Flag Exercise

In a Capture-the-Flag (CTF) competition, participants aim to find and exploit system vulnerabilities to "capture a flag" — a specific piece of information, data, or code hidden within the system.The primary objective is to provide a realistic, challenging experience that helps participants develop and refine their skills in a controlled environment.

A CTF exercise generally involves multiple teams, with several participants each, who compete to capture as many flags as possible within a set time. Each team has a set of objectives from the outset, and their mission is to work together to execute a strategy and achieve those goals.Success is a collaborative effort — teams assist each other to exploit vulnerabilities while defending their own systems against other teams, sharpening their communication and coordination along the way.

The Process Behind the Capture-the-Flag Exercise

The CTF process can be broken down into seven essential steps:

· Organizers develop scenarios and objectives and set up the necessary tools for a smooth experience.

· Participants learn the details of the exercise and familiarise themselves with the rules and guidelines.

· Participants explore and analyse the virtual environment to identify vulnerabilities and potential attack vectors.

· Once vulnerabilities are identified, teams develop and execute strategies to exploit them.

· Teams also defend their own systems from other teams by monitoring network traffic and analysing logs.

· Organizers track each team's progress and assess performance, then announce the scores and reveal the winners.

· A debriefing session reviews performances and provides actionable feedback on the strategies and techniques used.

Benefits of the Capture-the-Flag Exercise

Taking part in a CTF exercise can be extremely beneficial for both the organization and the participant.It is an excellent way to broaden your technical skills and knowledge — think of each challenge as a puzzle that calls on your knowledge of different cybersecurity domains and puts it into practice. The challenges help participants build real-world problem-solving ability by facing the true nature of cyber threats and learning strategies to mitigate them. A CTF competition is also an excellent platform for building a team's confidence and boosting an organization's cyber resilience.

Tabletop Exercise

A tabletop exercise is a security-incident preparedness activity that walks participants through the process of responding to simulated cyber incidents. It is entirely scenario-based and does not involve a live cyberattack. The main idea is to help organizations think through different risk scenarios and prepare for potential threats.

Throughout a tabletop exercise, participants work through their incident response plan by discussing questions such as:

· What happens in the event of a breach?

· How are roles and responsibilities divided within the team?

· Who leads the process, and what is their authority?

· What resources are available during the process?

Regularly conducting a tabletop exercise brings an organization a lot of benefits. First, it increases awareness and understanding of potential future threats.It also helps decision-makers evaluate the organization's overall incident preparedness and understand where to improve. Finally, clarifying roles and responsibilities in advance means everyone knows how to react when an incident occurs, and it lets participants practise the decision-making process effectively.

Other Cyber Security Exercise Formats

The formats above are the ones organizations run most often, but a comprehensive cybersecurity programme draws on several more. The most prominent are:

· Red team vs blue team. An adversarial exercise where an attacking red team is pitted against a defending blue team. It underpins the live-fire format above but is also run in its own right to measure real attack-and-defence capability. 

· Purple-team exercise. Rather than competing, red and blue teams collaborate — walking through attack paths together to close detection and response gaps. Best when the goal is improving coverage rather than comparing performance.

· Incident-response drill (functional exercise). A focused rehearsal of a specific part of the incident response plan — for example, isolating a compromised host or executing an escalation path end to end.

· Breach-and-attack simulation (BAS). Automated, continuous validation that safely runs known attack techniques against your controls to confirm what they actually catch.

· Ransomware-recovery exercise. A scenario centred on containment, backup restoration, and business-continuity decisions during a ransomware incident — increasingly important given the recovery costs cited above.

· OT/ICS exercise. Defence of industrial control systems and operational technology, often on a high-fidelity digital twin, so critical-infrastructure teams can practise without endangering physical processes.

· Cloud-security exercise. Scenarios built around cloud identity, misconfiguration, and workload compromise, reflecting where much of today's infrastructure actually lives.

· Digital-forensics and malware-analysis drills. Technical exercises that build the investigative skills — evidence handling, log analysis, reverse-engineering — needed after an incident.

· Crisis / executive exercise. A leadership-level session focused on business-priority decisions, risk acceptance, regulatory notification, and crisis communications rather than hands-on defence.

· Multi-organization (cooperative) exercise. Large, federated exercises that bring several organizations or nations together to practise coordinated defence — the model behind the largest international cyber exercises.

Different Names for the Same Exercises

Much of the confusion in this field is vocabulary rather than substance. Buyers, vendors and national bodies use different labels for the same activity, and a request for one thing often turns out to mean another. The terms below map onto the formats above.

· Cyber security simulation exercise. An umbrella term for any exercise run in a simulated environment rather than on production systems. In practice it usually means a live-fire exercise when people are being tested, or breach-and-attack simulation when controls are.

· Cyber attack simulation exercise. Emphasises the attacking side. Where a red team drives it, this is live-fire or red team vs blue team. Where software drives it continuously, it is breach-and-attack simulation.

· Cyber defence exercise. The same activity described from the defender's side, so normally live-fire. At national scale it also covers the large multi-organization cooperative exercises, where several teams defend a shared environment together.

· Cyber incident response exercise. Depends on how far it goes. Talked through around a table, it is a tabletop exercise. Rehearsing one specific procedure end to end, it is an incident-response drill. Run against a live attack on a range, it is live-fire.

· Cyber risk exercise. Usually a tabletop framed around risk decisions rather than technical response: which systems to take offline, what to disclose and when, what level of loss is acceptable while recovery runs.

· Strategic, management and decision-making exercises. Three labels for the leadership end of the spectrum. These are crisis or executive exercises, run without hands-on defence, focused on escalation, regulatory notification, communications and business-priority calls under time pressure. They are also the formats most often skipped, which is why the first serious incident is frequently the first time executives make these decisions at all.

The practical consequence is worth stating plainly: agree what an exercise is meant to test before agreeing what to call it. Two organizations can run something they both describe as an incident response exercise and test entirely different capabilities.

How Do You Organize a Cyber Security Exercise?

The formats differ, but the organizing sequence behind them does not change much. Whether you are running a three-hour tabletop or a five-day live-fire exercise, the same eight decisions have to be made, and in roughly this order.

· Start with the objective, not the format. Decide what you need to know afterwards that you do not know now. Whether detection works, whether the response plan survives contact, whether the team can hold a service up under pressure, whether executives can make a disclosure decision inside the regulatory window. The objective determines the format, not the other way round.

· Decide who takes part. Technical exercises tend to default to the SOC. Widening participation to incident response, IT operations, legal, communications and an executive sponsor is usually what turns an exercise from a training event into a test of the organization.

· Choose the format that fits. Match the objective to the comparison table above. Testing decisions and plans points to a tabletop; testing hands-on defence points to live-fire; testing whether controls catch known techniques points to breach-and-attack simulation.

· Build the scenario. Write the attack path, the injects and the decision points, and check that each one exercises something on your objective list.

· Prepare the environment. For technical formats this means standing up the range, the target systems and the telemetry participants will need. The closer it resembles the architecture your team defends day to day, the more the findings carry back.

· Set the scoring and observation up front. Decide what will be measured and who is watching before the exercise runs, not afterwards. Retrospective scoring produces arguments rather than evidence.

· Brief everyone, including the white team. Participants need the rules, the scope and the escalation path. The white team running the exercise needs to know when to intervene, when to escalate the pressure and when to stop.

· Run it, then debrief while it is fresh. Hold the hotwash immediately afterwards, and turn it into a written record with named owners and dates. Findings that leave the room in someone's memory do not get fixed.

Cyber Exercise Scenarios: Choosing What to Run

A scenario is the part participants actually experience, and it is where most exercises are won or lost. A generic scenario produces generic findings. The ones that change behaviour are built from the threats the organization would realistically face, running against systems it would realistically be running.

Scenarios that earn their place in most programmes include:

· Ransomware and recovery.

Containment, backup restoration and continuity decisions under time pressure. Restoring under pressure is a different thing from believing a backup exists.

· Phishing to lateral movement.

An initial foothold through a user, then privilege escalation across the estate. Tests detection at the point where most real intrusions begin.

· Supply-chain or third-party compromise.

An attacker arriving through a trusted supplier, integration or software update, where your own controls were never the first line.

· Insider activity.

Misuse by someone who already holds legitimate access, which defeats most perimeter-shaped thinking.

· Operational technology and industrial control.

Attacks with physical consequences, run on a high-fidelity replica so critical processes are never at risk.

· Cloud identity and misconfiguration.

Compromise through identity, permissions and exposed workloads, reflecting where most infrastructure now sits.

· Availability and denial of service.

Maintaining service availability while under sustained attack, which is often the outcome that matters most to the business.

Two practical rules apply whichever you choose. Build scenarios from your own threat model and architecture rather than from a library, and avoid material whose solutions are already published, which measures recall rather than skill.

How Cyber Security Exercises Are Scored

Scoring is what separates an exercise from a demonstration. It also varies more between formats than any other element, which is why the metrics column in the table above differs from row to row.

· Live-fire: Scored continuously across several dimensions at once: how long a service stayed available, how quickly an attack was detected and contained, whether required reports were filed, and how the team handled coordination. A single number rarely tells you anything useful on its own.

· Red team vs blue team: Scored on the adversarial exchange. How many attacks were detected and stopped, and how long the attacker went unnoticed.

· Threat hunting: Scored on what was found and at what cost. Threats identified, time to detection, and the volume of false positives generated getting there.

· Capture the flag: The most objective of the formats. Flags captured, time taken and final ranking, which is why it works as a competition and for talent spotting.

· Tabletop and executive exercises: Not scored numerically, and should not be. The output is a list of plan gaps, unclear roles and decisions nobody could make with the information available.

· Breach-and-attack simulation: Scored on control coverage. What proportion of known techniques the existing stack actually blocked or alerted on.

Whatever the format, scoring works best when participants know the criteria in advance and when results are used to direct training rather than to rank individuals. Exercises that feel like assessments get gamed, and the findings stop being honest.

Best Practices for Cyber Exercises

Across formats, the same handful of practices separate exercises that change something from exercises that produce a certificate.

· Let objectives drive the design. Every scenario element, inject and metric should trace back to something you set out to learn.

· Keep the environment close to your own. Findings carry back to production only as far as the exercise environment resembles it.

· Include the roles that get involved in a real incident. Legal, communications and executive decision-makers are part of incident response whether or not they were invited to the exercise.

· Instrument it. Capture logs, timings and decisions as the exercise runs. Without a record, the debrief becomes a conversation about impressions.

· Debrief fast and write it down. A hotwash immediately afterwards, then a short report with owners and dates against each finding.

· Repeat and compare. One exercise gives a snapshot. The value comes from running comparable exercises over time and watching the numbers move.

· Separate learning from evaluation. Teams that expect to be judged hide problems. Teams that expect to learn surface them, which is the entire point.

Top Examples of Cyber Security Exercises From CybExer

Now that we know what these exercises are and why they help, here are real CybExer examples — each noting the format and the capability tested.

Army Cyber Spartan — live-fire (British Army)

Army Cyber Spartan (ACS), one of the British Army's largest hands-on cyber exercises, has run annually for years — 2026 marks CybExer's seventh year supporting it on an Army-owned cyber range CybExer maintains. Built to mirror a modern SOC, its 2024 edition put 350+ participants across 33 teams into a live-fire environment. Capability tested: threat hunting, detection, analysis, and mitigation — scored across live response, detection, incident analysis, and team coordination rather than a single number. Read the full overview.

Cyber Capacity Building with the e-Governance Academy — CTF, threat hunting & live-fire

With the e-Governance Academy, CybExer runs exercises that build national cyber capacity. The EU-backed 2023 Moldova Cybersecurity Capacity Building Exercise drew 30+ public- and private-sector experts, pairing a Jeopardy-style CTF day (on the cyber range, using tools such as MISP and Security Onion) with a team threat-hunting exercise that closed in a hotwash. Outcomes were measurable: 83% learned new defensive techniques, 97% valued the range's realism, and 93% were satisfied with the hands-on content. The partnership has also delivered a Moldovan armed-forces live-fire exercise and a four-day live-fire drill in Albania for Western Balkans teams.

Defence Cyber Marvel 3 — competition

Defence Cyber Marvel 3 (DCM 3) is one of the largest cyber exercises in the world, hosting 1,100+ participants in 41 teams from 19 countries — including Germany, Ukraine, Japan, the US, and the UK — competing across technical challenges. Together with CR14, CybExer designed, built, and ran it end to end. Read the full overview.

Space Systems Software Security Testing Competition — CTF (space sector)

Beyond defence, CybExer ran a Capture-the-Flag competition for the space sector — the 2024 Space Systems Software Security Testing Competition, with SpaceIT and the Estonian Space Office — testing teams against realistic threats to satellites and ground stations on a SatOpSim scenario. The same formats run well beyond the military, too: for finance and banking (including DORA testing), academia, and critical-infrastructure operators.
