Introduction:
The digital landscape is fraught with evolving threats, making robust risk analysis a cornerstone of any effective cybersecurity strategy. A new initiative, offering a free, certified course in the EBIOS Risk Manager methodology, is democratizing access to this critical skillset, empowering a broader range of professionals to defend organizational assets.
Learning Objectives:
- Understand the core principles and methodological steps of the EBIOS Risk Manager framework.
- Learn to identify, analyze, and evaluate cybersecurity risks within a specific business context.
- Gain the practical knowledge to contribute to or lead a risk assessment workshop, culminating in an ANSSI-certified diploma.
You Should Know:
1. The Foundation: Understanding EBIOS Risk Manager
The EBIOS (Expression des Besoins et Identification des Objectifs de Sécurité) method is a structured approach for managing digital risks. This free course provides the foundational knowledge to apply this framework.
Step‑by‑step guide: The methodology is typically broken down into five key workshops:
1. Strategic Context: Define the perimeter of the study, the security bases, and the strategic objectives of the organization.
2. Digital Ecosystem: Model the information system by identifying the essential assets (e.g., Active Directory servers, customer SQL databases, API endpoints).
3. Threat Scenarios: Identify sources of threats (e.g., apt-group-4127), their motivations, and the attack methods they employ against your assets.
4. Feared Events: Determine the negative impacts that threat scenarios could have on strategic objectives (e.g., data breach, service downtime, reputational damage).
5. Risk Treatment: Build a security roadmap by selecting and prioritizing security controls to reduce risk to an acceptable level.
2. Asset Identification and Classification
Before risks can be analyzed, you must know what you are protecting. This step involves creating a comprehensive inventory of your critical digital assets.
Verified Command/Tool: Using a tool like `Lynis` on Linux for initial system auditing.
Install Lynis on Ubuntu/Debian sudo apt update && sudo apt install lynis Run a system audit sudo lynis audit system
Step‑by‑step guide: This command performs a comprehensive security scan of the system. The output will list available assets, system information, and potential security issues. For asset identification, focus on the sections detailing Available Shells, Accounts without password, World Writable Files, and Installed packages. This data feeds directly into the “Digital Ecosystem” workshop of EBIOS.
3. Mapping Your Network Perimeter
A clear understanding of your network’s boundaries and entry points is crucial for identifying how threats can access your assets.
Verified Command/Tool: Using `nmap` to perform a network discovery scan.
Perform a TCP SYN scan on a target network range nmap -sS 192.168.1.0/24 Perform service version detection on a specific host nmap -sV 192.168.1.10
Step‑by‑step guide: The `-sS` flag runs a stealth SYN scan, which is less likely to be logged than a full connect scan, to discover live hosts. The `-sV` flag probes open ports to determine the service and version running on them. The results create a map of your active systems and services, which is essential data for the EBIOS “Strategic Context” and “Digital Ecosystem” workshops.
4. Analyzing Threat Sources and Attack Vectors
This phase involves researching and documenting the “who” and “how” of potential attacks, linking them back to your identified assets.
Verified Command/Tool: Using the `Mitre ATT&CK Navigator` (a web-based tool, not a CLI command) to map techniques.
Navigate to `attack.mitre.org/resources/attack-navigator/`.
Create a new layer and search for techniques relevant to your assets (e.g., “Credential Dumping” for Windows domains, “Supply Chain Compromise” for software repositories).
Step‑by‑step guide: By using the ATT&CK Navigator, you can visually build a library of tactics, techniques, and procedures (TTPs) that are relevant to your organization. For example, if you have public-facing web servers, you would flag techniques like T1190: Exploit Public-Facing Application. This structured approach directly supports the “Threat Scenarios” workshop in EBIOS.
5. Technical Vulnerability Assessment
Identifying technical weaknesses in your assets is a key part of risk evaluation. This involves using automated tools to find known vulnerabilities.
Verified Command/Tool: A basic vulnerability check with the `Nessus` command-line interface or using OpenVAS.
Example of using OpenVAS (gvm-cli) to start a task (conceptual) gvm-cli --gmp-username admin --gmp-password password socket --xml "<create_task><name>My Asset Scan</name><config id='daba56c8-73ec-11df-a475-002264764cea'/><target id='c4e34bd0-8b5b-4e1f-9f0a-123456789abc'/></create_task>"
Step‑by‑step guide: While full command-line scans are complex, the concept is to use a vulnerability scanner to probe your assets. The scanner references CVE (Common Vulnerabilities and Exposures) databases to identify unpatched software, misconfigurations, and default credentials. The findings, often with a CVSS (Common Vulnerability Scoring System) score, provide quantitative data for the “Feared Events” workshop, helping to estimate the likelihood and impact of a breach.
6. Prioritizing Risks with a Quantitative Matrix
Not all risks are equal. The EBIOS method helps you prioritize by evaluating the likelihood and impact of feared events.
Verified Concept: Creating a Risk Matrix. While not a single command, this is a critical step. You can use a spreadsheet or GRC (Governance, Risk, and Compliance) platform.
Impact Scale: Define levels like 1 (Negligible), 2 (Minor), 3 (Significant), 4 (Major), 5 (Catastrophic).
Likelihood Scale: Define levels like 1 (Rare), 2 (Unlikely), 3 (Possible), 4 (Likely), 5 (Almost Certain).
Step‑by‑step guide: Plot each identified risk scenario on the matrix. A risk with a Likelihood of 4 and an Impact of 5 (Score: 20) is a critical priority. A risk with a Likelihood of 2 and an Impact of 3 (Score: 6) is a medium priority. This visual tool is the core output of the “Risk Treatment” workshop, guiding where to allocate security resources first.
7. Implementing Basic Technical Mitigations
Once risks are prioritized, you must implement controls. This often starts with foundational system hardening.
Verified Command/Tool: A Windows command to audit and enforce password policy.
Display the current password policy net accounts Set a minimum password length (via Command Prompt, run as Administrator) net accounts /minpwlen:14
Step‑by‑step guide: The `net accounts` command shows current settings like password length and lockout threshold. Enforcing a strong password policy (/minpwlen:14) is a direct mitigation against credential-based attacks identified in your risk analysis. This is a tangible action resulting from the EBIOS process, moving from analysis to implementation.
What Undercode Say:
- This training represents a significant shift towards state-sponsored upskilling, lowering the barrier to entry for high-quality cybersecurity education.
- The ANSSI certification adds immense credibility, making the diploma a valuable asset for job seekers and professionals aiming to validate their skills in a recognized framework.
The launch of this free, ANSSI-certified course is more than just a training opportunity; it’s a strategic move to bolster national and organizational cyber resilience. By standardizing and disseminating the EBIOS methodology, the Club EBIOS and ANSSI are creating a common language and process for risk management. This will lead to more consistent and effective security postures across French and international organizations. The overwhelming registration numbers indicate a massive, unmet demand for practical, certified training that doesn’t carry a high financial cost, challenging the business models of expensive, private training providers.
Prediction:
The widespread adoption of this free, certified training will rapidly elevate the baseline competency in cybersecurity risk assessment across a broad population. Within two years, we predict a measurable increase in the quality of risk assessments submitted to regulators and a corresponding decrease in breaches caused by fundamental risk management failures within organizations that have adopted this trained workforce. This initiative will force other national cybersecurity agencies to consider similar programs, potentially leading to a global standardization of core cybersecurity risk analysis practices.
