to Cybersecurity Risk Assessment Methods
Cybersecurity risk assessment is a critical component of any organization’s security strategy. Two prominent methodologies for managing cyber risks are CIS RAM (Center for Internet Security Risk Assessment Method) and EBIOS RM (Expression des Besoins et Identification des Objectifs de Sécurité – Risk Manager by ANSSI).
CIS RAM Overview
CIS RAM provides a pragmatic, operational approach based on CIS Controls:
– Aligns with established security best practices
– Focuses on digital asset risk assessment
– Prioritizes protection measures based on business impact
– Designed for quick implementation without disrupting operations

EBIOS RM Overview
The French ANSSI-promoted methodology offers strategic risk analysis:
- Widely used in France for regulatory compliance
- Focuses on attacker identification and motivation
- Provides detailed attack surface modeling
- Preferred by large enterprises and government organizations

You Should Know: Practical Implementation
CIS RAM Implementation Commands and Steps
1. Initial Assessment:
<h1>Download CIS Benchmarks</h1> wget https://workbench.cisecurity.org/files/benchmarks <h1>List available controls</h1> cis-controls-tool list
2. Risk Scoring:
<h1>Generate risk assessment template</h1> cis-ram generate-template --ig 2 > assessment.yaml <h1>Evaluate controls implementation</h1> cis-ram evaluate --file assessment.yaml
3. Remediation Planning:
<h1>Windows: Check control implementation status</h1> Get-CISControlStatus -Control "1.1" -Detailed <h1>Generate remediation report</h1> New-CISRemediationReport -Format HTML -Path ./report.html
EBIOS RM Implementation Commands and Steps
1. Threat Modeling:
<h1>Install EBIOS RM tools (French government versions)</h1> sudo apt-get install ebios-rm-tools <h1>Start new assessment</h1> ebios-rm new-assessment --name "Enterprise_Risk"
2. Attack Scenario Development:
<h1>Sample attack tree generation</h1>
from ebios import AttackTree
tree = AttackTree.create_scenario("Data Breach")
tree.add_threat_actor("APT Group")
tree.add_vulnerability("Unpatched System")
tree.generate_diagram()
3. Risk Treatment:
<h1>Generate risk matrix</h1> ebios-rm generate-matrix --format csv --output risks.csv <h1>Calculate risk scores</h1> ebios-rm calculate-scores --input risks.csv --output scores.json
Integration Approach
For comprehensive risk management:
- Start with CIS RAM for quick baseline assessment:
cis-ram quick-assessment --output baseline.json
2. Follow with EBIOS RM for detailed analysis:
ebios-rm import-cis --file baseline.json --name "Full_Assessment"
3. Continuous monitoring integration:
<h1>Set up automated risk monitoring</h1> crontab -e 0 12 * * * /usr/bin/cis-ram daily-check | ebios-rm update-assessment
What Undercode Say
The combination of CIS RAM and EBIOS RM provides organizations with both immediate actionable controls and deep strategic risk understanding. Key technical takeaways include:
1. Linux Security Commands:
<h1>Check system compliance with CIS benchmarks</h1> sudo lynis audit system <h1>Verify file integrity (Control 3.4)</h1> sudo aide --check
2. Windows Security Commands:
<h1>Audit account permissions (CIS Control 5)</h1> Get-LocalUser | Select Name,Enabled,PasswordRequired <h1>Check firewall status (CIS Control 9)</h1> Get-NetFirewallProfile | Select Name,Enabled
3. Network Security:
<h1>Scan for open ports (CIS Control 9)</h1> nmap -sV -T4 -O -F --version-light 192.168.1.0/24 <h1>Check for unnecessary services</h1> netstat -tulnp
4. Automation Scripts:
<h1>CIS Control 8: Audit Log Management</h1> import subprocess subprocess.run(["journalctl", "--since", "1 day ago", "--no-pager"])
5. Compliance Verification:
<h1>Check SSH configuration (CIS Control 5.2)</h1> sshd -T | grep -E "PermitRootLogin|PasswordAuthentication"
The optimal cybersecurity strategy combines the operational efficiency of CIS RAM with the comprehensive threat modeling of EBIOS RM, supported by continuous technical implementation and monitoring.
Expected Output:
1. CIS RAM baseline assessment report (JSON/HTML)
2. EBIOS RM threat model diagrams (PDF/PNG)
3. Automated compliance monitoring logs
4. Risk treatment plan with prioritized actions
5. Continuous improvement dashboard integrating both methodologies
