Introduction:
In a viral LinkedIn post, the fictional “Jean-Michel Acottay” satirically demonstrates how not to run a security program, making catastrophic decisions regarding EDR, risk analysis, and cloud sovereignty. While humorous, these scenarios highlight a dangerous reality: well-intentioned but misinformed leadership can create critical vulnerabilities. This article deconstructs each of Jean-Michel’s blunders, providing the correct technical implementations, risk management strategies, and infrastructure hardening steps every professional should know to avoid becoming a cybersecurity meme.
Learning Objectives:
- Implement proper Endpoint Detection and Response (EDR) deployment strategies across enterprise assets.
- Conduct a formal risk assessment (EBIOS RM) with correct scoping and asset identification.
- Differentiate between Disaster Recovery Plans (DRP) and Business Continuity Plans (BCP) with realistic testing procedures.
- Configure SIEM rules for modern (IoT) assets and secure cloud migration strategies.
- Understand the relationship between ISO 27001 and other management standards.
You Should Know:
- The EDR Folly: Deploying to Personal Devices Instead of Corporate Assets
Jean-Michel’s first mistake is installing EDR on personal PCs while leaving corporate workstations unprotected. This completely defeats the purpose of endpoint security, as corporate data resides on managed devices, not employee gaming rigs.
The Correct Approach:
To properly deploy EDR (using Microsoft Defender for Endpoint as an example), you must onboard corporate devices via Group Policy or Intune.
Linux (EDR Agent Installation):
Download the Microsoft Defender for Endpoint client wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb sudo dpkg -i packages-microsoft-prod.deb sudo apt-get update sudo apt-get install mdatp Configure the client with your Tenant ID sudo mdatp config cloud --value <YOUR_TENANT_ID>
Windows (PowerShell – Intune/Onboarding):
Download the onboarding script from Security Center Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser .\WindowsDefenderATPOnboardingScript.ps1 Start the service Start-Service -Name Sense
Step‑by‑step:
1. Identify all corporate assets via CMDB.
- Exclude personal devices via Conditional Access or Intune compliance policies.
- Deploy agents via MDM (Intune/Jamf) or Group Policy.
- Verify telemetry is flowing to the SIEM/SOAR platform.

The Risk Assessment Catastrophe: EBIOS RM on a Coffee Machine
Focusing risk analysis on a coffee machine while ignoring the critical database server is a classic scope failure. EBIOS (Expression des Besoins et Identification des Objectifs de Sécurité) is a robust French risk management method, but it requires proper asset valuation.
Executing a Proper EBIOS RM Workshop:
- Context Establishment: Define the “Heart of the Business” (e.g., the production server, customer data warehouse).
- Covered Assets: Security events must relate to feared events impacting these assets.
- Operational Scenarios: Map attack paths. Instead of “nuclear explosion,” use scenarios like “Ransomware infiltration via phishing email.”
- Mitigation: Implement compensating controls based on likelihood and impact scores. For a critical server, this means MFA, network segmentation, and immutable backups, not a coffee machine risk log.
3. The PRA (Disaster Recovery Plan) Reality Check
Testing a plan for a nuclear explosion is unrealistic. Disaster Recovery Plans must be tested based on likely infrastructure failures.
Practical DR Testing Commands & Procedures:
Linux (Testing Backup Integrity):
Mount a backup image to verify file integrity without full restore sudo mount -t ext4 /dev/sdb1 /mnt/backup_verify ls -la /mnt/backup_verify/var/www/ Unmount after verification sudo umount /mnt/backup_verify
Windows (PowerShell – Failover Cluster Testing):
Test the failover of a clustered role Get-ClusterGroup "SQL Server (Instance1)" | Move-ClusterGroup Validate the cluster configuration Test-Cluster
Step‑by‑step guide:
- Step 1: Define RPO (Recovery Point Objective) and RTO (Recovery Time Objective) based on business impact analysis.
- Step 2: Conduct a “Tabletop Exercise” discussing roles.
- Step 3: Perform a technical “Failover Test” in a isolated network segment, not a full-scale nuclear simulation.
4. The SOC Blind Spot: Smartwatch Logging
Jean-Michel wants to monitor smartwatches but ignores server logs. However, IoT monitoring is becoming critical. If you must monitor smartwatches or wearables (for IP leakage or insider threat), you need API integrations.
SIEM Ingestion for IoT/Wearables (e.g., using Splunk or ELK):
If the smartwatch syncs to a cloud provider (Garmin/Apple/Google), you can ingest logs via API if the device is managed by MDM.
API Configuration (cURL to fetch logs from management console):
curl -X GET "https://api.mdm-provider.com/v1/devices?type=wearable" \ -H "Authorization: Bearer <YOUR_API_KEY>" \ -H "Content-Type: application/json" | jq '.' > wearable_devices.json
Splunk Forwarder Input (Monitoring local Bluetooth logs if available on gateway):
inputs.conf on a management server [monitor:///var/log/bluetooth_devices.log] index=endpoint sourcetype=iot:bluetooth disabled = false
Step‑by‑step:
- Identify the data source (Cloud API, MDM, or Gateway).
- Write a custom script/connector to push logs to the SIEM.
- Create correlation rules (e.g., “Smartwatch detected leaving geo-fence during work hours”).

Sovereignty & Cloud Migration: Rejecting Microsoft for a Free Chinese Host
Trading Microsoft for an untrusted, free provider is a massive supply chain risk. “Sovereignty” requires data residency, jurisdictional control, and supply chain verification.
Secure Cloud Migration (Hardening a VPS/Hosting):
If you must move away from big providers, do it securely on a sovereign cloud or a hardened dedicated server.
Linux Server Hardening (Post-Migration):
Update system sudo apt update && sudo apt upgrade -y Configure Uncomplicated Firewall sudo ufw default deny incoming sudo ufw default allow outgoing sudo ufw allow ssh sudo ufw allow https sudo ufw enable Fail2Ban for brute force protection sudo apt install fail2ban -y sudo systemctl enable fail2ban
Auditing the Supply Chain:
Verify the data center location, compliance certifications (ISO 27001, SOC2), and physical security controls before signing a contract.
6. Certification Confusion: ISO 27001 vs. ISO 18000
Jean-Michel confuses ISO 27001 (Information Security) with ISO 18000 (not a security standard—likely a slip for ISO 22301 (BCM) or OHSAS 18001 (Health & Safety)). You cannot substitute an InfoSec cert with an HR safety cert.
Implementing ISO 27001 Controls:
1. Scope Definition: Define the ISMS boundaries.
- Annex A Controls: Implement the relevant controls (A.5 – A.18).
3. Evidence Gathering:
Linux (Evidence of Access Control – A.9):
Check user access logs last -a | grep "still logged in" Check sudo permissions sudo cat /var/log/auth.log | grep sudo
Windows (Evidence of Patch Management – A.12):
Get-HotFix | Where-Object {$_.InstalledOn -gt (Get-Date).AddDays(-30)}
What Undercode Say:
- Key Takeaway 1: Security architecture must be asset-centric. Deploying EDR to personal devices or analyzing coffee machines misses the actual risk surface. Always prioritize based on data value and threat modeling (e.g., STRIDE or PASTA).
- Key Takeaway 2: Compliance and sovereignty are not “vibes.” They require technical controls (firewalls, access logs) and legal vetting. Moving to a free, unvetted host introduces more risk than staying with a compliant hyperscaler.
- Analysis: Jean-Michel’s satire works because it highlights a gap in technical competency versus executive authority. A CISO must bridge the gap between boardroom strategy and the command line. Testing DR for nuclear war is pointless when phishing emails are the real threat. The industry needs fewer “Ketchup-outside-the-sandwich” managers and more hands-on leaders who understand that logging, patching, and proper scoping are the foundations of security.
Prediction:
As the cybersecurity skills gap widens, we will see a rise in “Accidental CISOs” like Jean-Michel, leading to an increase in catastrophic breaches caused by fundamental misconfigurations rather than advanced zero-days. This will force boards to demand more technical certifications and hands-on technical audits for leadership roles, shifting focus back to operational resilience over theoretical compliance.
