Cybersecurity risk mapping: a complete guide to identifying and managing threats in 2026

With cyberattacks on the rise, and becoming ever more frequent and complex, cybersecurity risk mapping has established itself as a key tool for organisations that want to protect their critical assets. Controlling cyber risk is paramount in order to anticipate threats and avoid catastrophic consequences for IT systems, sensitive data and business continuity. This article guides you step by step through understanding, implementing and maintaining an effective cybersecurity risk map.

Risk mapping builds on a rigorous cybersecurity risk analysis, which identifies the threats to deal with first and ranks them.

What is cybersecurity risk mapping?

Cybersecurity risk mapping is a methodical process that aims to identify, assess and rank the potential threats weighing on an organisation’s critical assets, whether data, infrastructure or systems. This process is essential to provide a clear view of cyber risks and to establish an effective strategy for managing and reducing them.

It includes the mapping of the information system (IS), which is a process of graphical and structured representation of all the components, information flows and interactions within an organisation’s IS. This includes software, hardware, networks, databases, applications, business processes and the relationships between them.

What are the objectives of risk mapping?

Risk mapping has multiple objectives:

• Identify critical assets and understand their importance within the organisation (sensitive data, critical systems, network infrastructure, etc.).
• Analyse the threats weighing on these assets, whether technical vulnerabilities, external threats (cyberattacks, phishing, ransomware) or internal ones (human error, internal security flaws).
• Assess the impact and likelihood of these risks in order to measure the potential severity of each threat for the organisation.
• Rank risks according to their criticality, so as to focus efforts on the most serious and most likely threats.
• Implement preventive actions to limit the organisation’s exposure to the identified risks and strengthen security.
• Create visualisation tools such as dashboards or graphical representations, for a better understanding and communication of risks to senior management and other stakeholders.

Good risk mapping makes it possible to take informed decisions, based on clear data and an overall view of risks. It helps prevent cyberattacks by anticipating vulnerabilities before they are exploited, and by making it easier to implement a prevention and response plan adapted to the specific needs of each organisation.

What types of IS mapping exist?

IS mapping is a valuable tool for organisations, because it gives them a better understanding of the IT environment in which they operate. It makes strategic decision-making easier, as well as the identification of performance problems, risk management, resource optimisation, the planning of technology upgrades and the implementation of appropriate security measures.

It should be noted that IS mapping is a continuous process, because an organisation’s IT landscape is constantly changing. It is therefore important to keep the IS map up to date so that it remains relevant and useful in managing the organisation’s IS.

Depending on the software solution you choose, your company will have access to various elements, the most common of which are the following:

Application and system dashboard

This dashboard gives you a comprehensive view of the software applications, operating systems, databases and other software components used in your IS.

Infrastructure dashboard

You have a representation of the IT hardware, such as servers, computers, routers, network switches and other physical equipment.

Information-flow dashboard

The software gives you a graphical representation of the paths taken by data and information through the various applications, databases and business processes. It is a valuable aid to better understand the complexity of your IT network.

Interconnection dashboard

You can identify at a glance the physical and logical connections between the various components of the IS, including your networks, your communication protocols and the software interfaces.

Business-process dashboard

It allows you to identify all the business processes supported by the IS and their relationship with the various applications and systems. A business process that is poorly understood or poorly applied is sometimes the cause of a GDPR compliance failure. The IS mapping software offered by Make IT Safe is in fact a control tower that is both powerful and intuitive. It allows the CISO to steer the security and compliance of the whole company with complete confidence.

Our Make IT Safe software gives you these various dashboards for the management of your cyber risks.

Which cyber risks can mapping help reduce?

By showing which assets are exposed and through which paths, mapping helps to reduce the most common cyber risks.

Malware attacks

Malicious software, such as viruses, worms, Trojan horses and ransomware, can compromise the security of IT systems by damaging data, disrupting operations or stealing sensitive information. More and more often, this type of attack is followed by ransom demands (ransomware).

Phishing attacks

Phishing is a technique in which cybercriminals send fraudulent emails or messages in order to deceive users. These users are encouraged, sometimes in subtle ways, to disclose personal information such as passwords, credit card numbers or login credentials.

Denial-of-service attacks (DDoS)

They aim to make a service unavailable by saturating the targeted servers or networks with repeated requests. The computers freeze and make the resources inaccessible to users. A server is said to have “gone down” when it is no longer able to respond.

Software and system flaws

Any computer program, whatever it may be, can contain blocks of code that offer possibilities for circumvention. This happens mainly when queries are entered to interrogate a database.

It can also happen when a network port that should normally remain closed to the outside is used. Cybercriminals systematically test every potential flaw in a piece of software or a network (including mobile networks) in order to find a way into the area protected by IT security.

Human error and negligence

Cybercriminals have an aura of IT “whizz kids”, mainly thanks to the films and series that glorify their exploits. In reality, they mostly exploit the negligence and mistakes of company staff. This can simply be the use of a password that is too simple, never changed or carefully left on a Post-it.

You probably won’t want to believe it, but one of the most used passwords in 2022 was… 123456 (Source: BDM)!

As this list shows, it is important for individuals and organisations to take security measures that match these growing risks. To identify them quickly and exhaustively, IS mapping is a very effective protective weapon.

How can mapping help identify cyber risks?

Make IT Safe has given you a fairly broad overview of all the types of risk that exist within an IS. This concerns:

• The assets essential to the proper functioning of the company.
• The dependencies that may exist between the various components of your IS.
• The information flows that may be vulnerable, and those that must only be known to certain employees.
• The business processes that must comply with the GDPR.

Mapping makes it possible to assess the security measures currently in place for each component of the system. This includes identifying systems that have not been updated, vulnerable applications, inadequate security configurations, and so on.

By combining the information from the IS map with vulnerability analyses, it is possible to identify potential security flaws in the system. Once the weaknesses have been identified, your CISO will be able to take corrective measures with far greater peace of mind, to strengthen security and GDPR compliance.

The benefits of cyber risk mapping for CISOs and DPOs

Chief Information Security Officers (CISOs) and Data Protection Officers (DPOs) play a central role in managing cyber risks within their company.

Risk mapping then becomes an indispensable strategic tool for these profiles, enabling them to ensure a clear and structured view of the threats weighing on the organisation.

Here is why risk mapping is essential for CISOs and DPOs:

• Giving visibility to senior management: risk mapping allows CISOs and DPOs to provide a detailed and visual report to senior management. It gives them a clear overview of the state of the risks the company faces. This visibility helps justify investments in cybersecurity and guide strategic decisions on risk management.

• Prioritising security actions: once the risks have been mapped, it is easier for CISOs to prioritise security measures. Rather than trying to deal with all risks at the same time, they can concentrate on the threats that are most critical for the organisation, whether they are linked to technical vulnerabilities or to human threats.

• Protecting sensitive assets: CISOs and DPOs must make sure that the organisation’s critical assets (confidential data, IT systems) are well protected. Risk mapping allows them to identify the weak points in the security chain and correct them quickly, before they are exploited by cyberattackers. This includes corrective actions such as updating software, strengthening access controls or training employees.

• Complying with regulations: regulations such as the GDPR or the NIS 2 Directive, as well as the ISO 27001 standard, require organisations to have robust arrangements to protect data and systems. Risk mapping is an indispensable condition for complying with these legal requirements and avoiding the financial and legal penalties that could result. By demonstrating that the organisation has a clear view of its risks and has taken the necessary measures to mitigate them, CISOs and DPOs can prove compliance to regulators.

• Making collaboration with partners and suppliers easier: companies are increasingly part of a complex ecosystem in which they have to work with suppliers and partners. Risk mapping makes it possible to assess third-party risks and to check that partners comply with appropriate security standards. This contributes to overall security management, taking into account not only internal risks but also those linked to external players.

• Allocating budgets more effectively: the budgets to be allocated to the company’s security strategy can be better distributed and, above all, prioritised. Too many companies still take these costly decisions only after suffering a cyberattack that has sometimes threatened the very survival of their organisation.

• Reducing the costs of security incidents: risk mapping makes it possible to anticipate security incidents by identifying vulnerabilities and potential threats upstream. Preventing incidents often costs less than managing them. A well-prepared company reduces business interruptions, remediation costs and possible regulatory fines. This makes it possible to move from reactive incident management to a proactive approach, reducing not only financial costs but also operational impacts.

• Strengthening stakeholder trust: customers, partners and other stakeholders are increasingly concerned about the security of the information they share with companies. An organisation with robust risk mapping inspires more trust, because it shows a clear commitment to cybersecurity. In an environment where data security is becoming a differentiating factor, having a risk map and a transparent security policy can be a market advantage.

For CISOs and DPOs, risk mapping is an essential lever for regaining control over the security of systems and data, while making communication with senior management, business teams and external partners easier.

How do you put cyber risk mapping in place?

Putting cyber risk mapping in place requires a structured method, in several steps, to ensure exhaustive coverage of the threats weighing on the organisation.

Each of these steps is essential to obtain a precise view and definition of the risks, their impact and the measures to take to control them.

Step 1: Collect information

This concerns existing documents, diagrams, hardware and software inventories, data on business processes, and so on. All the information that may have commercial or strategic value for other organisations.

Step 2: Identify assets

Based on the information collected in the first step, identify the organisation’s critical assets and rank them in order of importance: servers, databases, applications, networks, business processes, sensitive data, etc.

These assets are the elements essential to the proper functioning of the company, and their compromise could have a significant impact on operations. They can include:

• Sensitive data: customer information, personal data, financial records, etc.
• IT systems: servers, networks, critical applications
• Physical infrastructure: IT equipment, data centres
• Business processes: strategic activities that require particular protection, such as the management of financial transactions or logistics

By giving each asset a name and assigning it a criticality value, you thus begin to create measurable indicators (KPIs) for your risk-mapping software.

It is vital to understand the value of these assets for the company and to quantify the associated risks. Using risk-mapping software makes it possible to automate this step and to inventory assets precisely and exhaustively. By centralising all the information in a single tool, it becomes easier to follow how risks evolve.

Step 3: Establish relationships

Identify the relationships and dependencies between the various assets of the IS. For example, the dependencies between network connections, or between information flows. Another example: integrations between applications, or dependencies between business processes.

Step 4: Create diagrams

Our Make IT Safe software includes graphical modelling tools such as block diagrams, flow diagrams, architecture diagrams or concept maps. They allow you to give a clear representation of the assets, the dependencies and the information flows.

Step 5: Risk analysis

Once the diagrams have been drawn up, organise meetings between all the players involved in your security strategy and carry out a risk analysis together. This is done from your IS mapping solution, by identifying the potential vulnerabilities and the risks associated with each asset of the IS.

Assess the possible consequences of threats and incidents on the confidentiality, integrity and availability of data by ranking them according to their criticality, that is to say their capacity to cause significant damage to the company.

The assessment criteria include:

• Financial impact: what would the losses be if an asset were compromised? This includes the costs of repair, of business interruption, and potentially of regulatory penalties.
• Repercussions on reputation: how would the company be perceived if an incident affected its data or systems? Loss of customer trust, tarnished image.
• Legal consequences: in the event of a personal data breach, regulations such as the GDPR impose financial penalties that can be substantial.
• Availability of services: an incident could lead to an interruption of operations, which would have direct effects on business continuity.

This assessment must also take into account the likelihood of each risk occurring. Some risks, although very serious, may be unlikely, while other, less critical risks may be more frequent. The aim of the method is to rank risks according to these two criteria in order to focus on the most urgent.

Step 6: Create security measures and put an action plan in place

Once the risks have been assessed and ranked, it is time to prioritise the security measures. This step consists of drawing up an action plan that reduces exposure to the identified risks. The measures to take can include:

• Adapting and strengthening security policies: reviewing access policies, segmenting the network, implementing reinforced access controls and intrusion detection systems.
• Updating software and systems: to correct known vulnerabilities and reduce the risk of exploitation by attackers.
• Planning regular backups: of critical data (customer files, databases, system configurations), on site or in the cloud, to restore quickly after an incident and limit data loss.
• Raising employee awareness: training staff in cybersecurity best practices to reduce the risk of human error.
• Putting a business continuity plan in place: providing fallback solutions in the event of an incident to limit service interruptions.
• Checking the GDPR rules in force: for the protection of personal data.

These actions must be regularly monitored and adjusted as threats evolve. The aim is to continuously improve the organisation’s resilience to cyberattacks and other security incidents.

All these measures will be identified and tracked in your mapping software.

What are the best practices for maintaining and updating your risk map?

Effective risk mapping is not a static document. It must be regularly updated to remain relevant as threats and IT systems evolve. This means adopting a proactive and collaborative method to make sure risks are continuously identified, assessed and managed.

Continuous monitoring and periodic review of risks

Threats are constantly evolving, as are internal vulnerabilities and IT systems. It is therefore essential to update the risk map regularly to reflect these changes. Here are a few best practices to follow:

• Continuous monitoring: use real-time monitoring tools to detect new threats or vulnerabilities that could affect critical assets. These tools make it possible to adjust the risk map quickly.
• Periodic reviews: include in your method regular reviews of the map, at least once a year, or after any major change in the IT infrastructure (e.g. system updates, integration of new tools or suppliers).
• Regular tests: carry out incident simulations (resilience tests, recovery plan tests) to check the effectiveness of the security measures in place and adjust the map accordingly.

The aim is to make sure the map remains relevant and reflects the real threats the organisation faces.

Collaboration with the various stakeholders

Risk management is the business of the whole organisation. It is therefore crucial to involve business teams, external partners and employees at every level in the process of updating the risk map. Here is how:

• Involve internal teams: business process owners, CIOs and security teams must work together to identify new risks and propose corrective actions. The map must be shared with these teams so that they have a common view of the risks.
• Work with suppliers: more and more attacks come through third parties. It is therefore important to assess supplier-related risks and to maintain a regular dialogue with suppliers to make sure they follow sound security methods and practices.

This collaboration makes it possible to guarantee an overall view of risks and to make sure all stakeholders take the necessary measures to protect the organisation.

Integrating risk mapping into the overall cyber strategy

Risk mapping must be integrated into a broader cybersecurity strategy. It must not be an isolated exercise, but rather a foundation on which security governance rests. Here are a few tips to ensure this integration:

• Alignment with strategic objectives: risk mapping must support the company’s overall objectives, particularly in terms of business continuity, data protection and compliance.
• Using the map as a decision-making tool: risk mapping can be used to guide decisions on budget allocation, the prioritisation of security projects and the choice of technology partners.
• Continuous training of teams: for the map to remain useful, teams must be trained on new risks and on changes in cybersecurity methods.

By integrating risk mapping into an overall strategy, organisations can improve their resilience to cyber threats and strengthen their ability to react quickly in the event of an incident.

What are the links between risk mapping and regulatory compliance?

Risk mapping is not limited to a simple representation of threats: it is an essential tool for guaranteeing compliance with the regulations in force. Here is how it contributes to this compliance:

• Identification of risks relating to personal data: the GDPR, for example, requires companies to identify the risks relating to the processing of personal data. Risk mapping makes it possible to visualise the sensitive points in data processing and to implement measures to protect them.

• Monitoring of corrective actions: risk mapping makes it possible to track the actions put in place to meet regulatory requirements, such as strengthening the security of systems, access management or raising employee awareness.

• Documentation and auditability: good risk mapping makes it easier to create the monitoring documents needed to prove compliance during audits. This allows CISOs and DPOs to demonstrate that efforts have been made to identify and manage risks in accordance with legal requirements.

• Planning internal audits: by mapping risks, companies can better plan their internal and external audits to make sure their cybersecurity practices comply with the standards and regulations in force.

How do you choose your cyber risk-mapping software?
