Introduction:
As digital threats like phishing, quishing, and data theft increasingly target local governments, the implementation of the NIS2 directive has become a critical mandate for municipalities. The recent election of a cybersecurity expert to a city council marks a pivotal shift from reactive incident response to proactive, immersive community vigilance. This initiative, leveraging a “From Fiction to Reality” training methodology, aims to build a “CyberMairie” (Cyber City Hall) that transforms every citizen into an active defender against cyber threats, creating a replicable model for national resilience.
Learning Objectives:
- Understand the core requirements of the NIS2 directive as they apply to local government entities and critical infrastructure.
- Learn practical, immersive techniques for community-wide phishing and quishing awareness campaigns.
- Explore technical configurations and commands for hardening local network infrastructure against common attacks.

The NIS2 directive expands the scope of cybersecurity regulations to include medium-sized and large entities in essential and important sectors, which now explicitly includes public administration at the local level. For a “CyberMairie,” compliance is not just a legal checkbox but a framework for operational resilience. This involves rigorous incident response capabilities, supply chain security, and management accountability.
To begin hardening a local network against the threats mentioned—such as data theft and phishing—system administrators must implement fundamental security controls at the perimeter and endpoint levels. Below are verified commands and configurations for both Linux and Windows environments to establish a baseline of security hygiene.
Linux (Ubuntu/Debian) – Firewall Hardening:
A robust firewall is the first line of defense. Using `ufw` (Uncomplicated Firewall), you can restrict access to administrative services and log suspicious activity.
Enable UFW and set default policies to deny incoming traffic sudo ufw default deny incoming sudo ufw default allow outgoing Allow essential services only sudo ufw allow 22/tcp comment 'SSH for admin' Restrict source IPs if possible sudo ufw allow 80/tcp comment 'HTTP' sudo ufw allow 443/tcp comment 'HTTPS' Enable logging for denied packets to monitor for port scans or probes sudo ufw logging on Enable and check status sudo ufw enable sudo ufw status verbose
Windows (PowerShell) – Network Threat Mitigation:
For Windows-based municipal servers and endpoints, leveraging built-in security features like the Microsoft Defender Firewall and Attack Surface Reduction (ASR) rules can prevent phishing payloads from executing.
Run as Administrator: Block all inbound connections and log dropped packets Set-NetFirewallProfile -Profile Domain,Public,Private -DefaultInboundAction Block -LogFileName %windir%\system32\LogFiles\Firewall\pfirewall.log -LogAllowed False -LogBlocked True Enable Windows Defender Exploit Guard (ASR) rules to block Office applications from creating child processes (common in phishing macros) Add-MpPreference -AttackSurfaceReductionRules_Ids D4F940AB-401B-4EFC-AADC-AD5F3C50688A -AttackSurfaceReductionRules_Actions Enabled
Step‑by‑step guide for NIS2 Incident Reporting:
- Establish a Single Point of Contact (SPoC): Designate a contact for incident notifications to the relevant Computer Security Incident Response Team (CSIRT).
- Implement Centralized Logging: Use a SIEM or a simple centralized syslog server (
rsyslogon Linux) to aggregate logs. This satisfies NIS2’s requirement for evidence preservation.On Linux syslog server, edit /etc/rsyslog.conf to accept remote logs module(load="imudp") input(type="imudp" port="514") module(load="imtcp") input(type="imtcp" port="514")
- Define Incident Tiers: Categorize incidents as “early warning” or “substantial” to meet the 24-hour and 72-hour notification deadlines mandated by NIS2.

Immersive Phishing & Quishing Awareness (The FF2R Method)
The post highlights a critical challenge: moving beyond boring, annual training to “awakening consciences before the incident.” The “From Fiction to Reality” (FF2R) method leverages emotional immersion—treating learning like watching a Netflix series—to improve memory retention. This approach is scientifically backed: emotional engagement strengthens neural pathways.
To implement this technically, security teams can create realistic, but safe, simulation environments. For phishing, use open-source frameworks to simulate credential harvesting. For quishing (QR code phishing), which is increasingly used to bypass email filters, you can set up controlled simulations using custom QR codes that redirect to educational landing pages.
Setting up a Phishing Simulation (Using GoPhish):
- Deploy GoPhish: A popular open-source phishing framework. Install it on a controlled server.
Download and extract GoPhish on Linux wget https://github.com/gophish/gophish/releases/download/v0.12.1/gophish-v0.12.1-linux-64bit.zip unzip gophish-v0.12.1-linux-64bit.zip sudo ./gophish
- Configure Sending Profile: Set up an SMTP relay or a test email server (like MailHog) to avoid accidentally spamming external addresses.
- Create Landing Pages: Clone the login page of a municipal service (e.g., VPN portal) but modify the backend to capture credentials and display a training message instead of storing them.
Quishing Analysis Commands:
Before scanning a suspicious QR code, security personnel should analyze the underlying URL. On Linux, you can decode QR codes without visually displaying them to check for malicious domains.
Install zbar-tools for QR decoding sudo apt install zbar-tools Scan a QR code image and extract the URL without opening it zbarimg --quiet --raw suspicious_qr.png Then use curl to analyze the URL's headers and redirects safely curl -I -L "http://example.com/suspicious-link"
- Building a “CyberMairie” with API Security and Cloud Hardening
As municipalities adopt cloud services and interconnected platforms, the attack surface expands beyond the local network. API security is paramount, especially when city services (like tax portals or resident databases) are exposed. Hardening these APIs against injection and authentication flaws is essential to prevent data breaches.
API Security Testing (Using OWASP ZAP on Linux):
- Install OWASP ZAP: A web application security scanner.
sudo apt update sudo apt install zaproxy
- Automated Scan: Run a quick baseline scan against an internal API endpoint to identify common vulnerabilities like SQL injection or broken authentication.
zap-cli quick-scan --self-contained --spider -r -l Informational http://city-api.local/endpoint
Windows – Cloud Hardening with Azure Policy:
If the municipality uses Microsoft 365 or Azure, hardening against identity-based attacks (phishing leading to credential theft) is critical.
Connect to Azure AD (now Entra ID) to enforce Multi-Factor Authentication (MFA)
Install-Module MSOnline
Connect-MsolService
Enable MFA for all users
$users = Get-MsolUser -All
foreach ($user in $users) {
$auth = New-Object -TypeName Microsoft.Online.Administration.StrongAuthenticationRequirement
$auth.RelyingParty = ""
$auth.State = "Enabled"
Set-MsolUser -UserPrincipalName $user.UserPrincipalName -StrongAuthenticationRequirements $auth
}
4. Vulnerability Exploitation and Mitigation in Local Networks
The threats mentioned—”Arnaques en ligne” (online scams) and “Vol de données” (data theft)—often stem from unpatched vulnerabilities in public-facing systems. Municipalities frequently run legacy software or misconfigured web servers. A proactive vulnerability management program is a cornerstone of the NIS2 directive.
Linux – Scanning for Vulnerabilities with Lynis:
Lynis is a security auditing tool that helps identify misconfigurations and missing patches.
Install Lynis sudo apt install lynis Run an audit on the local system sudo lynis audit system Look for warnings and suggestions in the report to harden the system against exploitation
Windows – Mitigating Lateral Movement:
After an initial phishing compromise, attackers often use tools like Mimikatz or PowerShell to move laterally. Disabling WDigest authentication can prevent credential dumping.
Registry key to disable WDigest (stops plaintext passwords in memory) reg add HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\WDigest /v UseLogonCredential /t REG_DWORD /d 0 /f Restrict PowerShell execution policy to prevent malicious scripts Set-ExecutionPolicy -ExecutionPolicy AllSigned -Scope LocalMachine
What Undercode Say:
- Key Takeaway 1: Local governance is the new frontline for NIS2 compliance; technical audits and centralized logging are non-negotiable for incident response.
- Key Takeaway 2: Traditional training fails; immersive, simulation-based learning (FF2R) significantly improves human resilience against phishing and quishing attacks.
- Key Takeaway 3: A “CyberMairie” requires a holistic approach—integrating perimeter hardening (firewalls), endpoint controls (ASR rules), and robust API/cloud security to protect citizen data from modern threats.
The shift from viewing cybersecurity as an IT issue to a foundational civic service is underway. By combining the rigor of NIS2 compliance with innovative human-centric training, local entities can transform vulnerabilities into collective strength. The technical commands and configurations outlined provide the actionable foundation for this transformation, ensuring that the “CyberMairie” is not just a concept, but a hardened reality.
Prediction:
As more municipalities adopt “CyberMairie” frameworks, we will see a surge in demand for hyper-localized security operations centers (SOC) and community-driven threat intelligence sharing. The integration of AI-driven training platforms that adapt to user behavior will become standard, moving beyond annual compliance to continuous, adaptive resilience. The success of these local models will likely influence national policy, creating a distributed defense model that is harder for adversaries to penetrate than centralized, one-size-fits-all solutions.
