The LinkedIn post highlights an urgent need for a Junior Network Security Engineer in Lyon, France, focusing on GRC (Governance, Risk, Compliance) and network security tasks. Below are the key cybersecurity skills and responsibilities extracted from the job description:

Primary Responsibilities:

  • Writing and reviewing IT security documents
  • Tracking and patching system vulnerabilities
  • Server decommissioning
  • Handling security tickets
  • Ensuring NIS2 compliance
  • Strengthening IT security infrastructure
  • Drafting security procedures
  • Conducting security audits
  • User training and awareness

Required Technical Skills:

  • Vulnerability patching (e.g., Linux/Windows updates)
  • ISO 27001 compliance
  • Firewall management (Fortinet, Palo Alto)
  • EDR (Endpoint Detection & Response)
  • VPN, IPsec, SSL configurations
  • Security governance frameworks

You Should Know:

1. Vulnerability Patching (Linux & Windows)

  • Linux (Debian/Ubuntu): 
    sudo apt update && sudo apt upgrade -y  Update all packages
sudo unattended-upgrade --dry-run -d  Check automatic security updates
  • Windows: 
    wuauclt /detectnow /updatenow  Force Windows Update check
Get-WindowsUpdate -Install -AcceptAll  Install all pending updates (PS Windows Update Module)

2. Fortinet Firewall Commands

config firewall policy 
edit 0 
set srcintf "port1" 
set dstintf "port2" 
set srcaddr "192.168.1.0/24" 
set dstaddr "10.0.0.0/8" 
set action accept 
set schedule "always" 
set service "ALL" 
next 
end

3. EDR (Endpoint Detection & Response) Checks

  • Check running processes (Linux): 
    ps aux | grep -i "malicious-process" 
chkrootkit  Rootkit scanner 
rkhunter --check  Malware detection

4. VPN & IPsec Setup (StrongSwan Linux)

sudo apt install strongswan 
sudo ipsec start 
sudo ipsec status  Check VPN tunnels

5. NIS2 Compliance Checklist

  • Log monitoring (Linux): 
    journalctl -u sshd --no-pager | grep "Failed"  Check SSH brute-force attempts
  • Windows Event Logs: 
    Get-WinEvent -LogName Security -MaxEvents 50 | Where-Object {$_.ID -eq 4625}  Failed logins

What Undercode Say:

This role demands a junior engineer with mid-level skills, including GRC, firewall management, and compliance (NIS2/ISO 27001). Key takeaways:
– Patch vulnerabilities immediately (Linux/Windows).
– Monitor logs for unauthorized access.
– Use EDR tools (CrowdStrike, SentinelOne).
– Configure firewalls (Fortinet CLI).
– Automate compliance checks (NIS2, ISO 27001).

Expected Output:

A junior security engineer must master GRC, network hardening, and compliance while handling vulnerability management and firewall configurations.
