Automating GDPR Compliance: From "Paper Policy" to Enforced Infrastructure

It is May 2020, and if you are still managing server compliance with Excel spreadsheets and manual checklists, you are already behind. As a CTO operating in the Norwegian market, the pressure isn't just technical—it's legal. With Datatilsynet (The Norwegian Data Protection Authority) ramping up audits and the ongoing uncertainty surrounding the Schrems II case potentially invalidating the Privacy Shield, reliance on US-controlled infrastructure is becoming a massive risk factor.

Compliance cannot be a quarterly event. It must be a continuous state of your infrastructure. If a sysadmin opens port 22 to the world for "testing" and forgets to close it, your compliant status is gone in milliseconds. The solution is treating Compliance as Code.

In this guide, we will move beyond theory. We will build a compliance baseline using Ansible for enforcement and OpenSCAP for verification, ensuring your VPS Norway infrastructure meets strict EU standards without killing your team's velocity.

The Architecture of Trust: Why "Cloud" is Too Vague

Before writing a single line of YAML, we must address the foundation. You cannot automate security on a platform you don't control. Many providers offering "cheap VPS" are actually reselling OpenVZ containers where you share a kernel with hundreds of other tenants. You cannot modify sysctl parameters to mitigate network stack attacks if you don't own the kernel.

Pro Tip: Always verify the virtualization technology. For serious compliance workloads, we require KVM (Kernel-based Virtual Machine). This ensures full isolation. At CoolVDS, every instance is KVM-based, meaning your memory and NVMe storage I/O are yours, and your kernel parameters are writable. This is non-negotiable for hardening.

Step 1: The Enforcement Layer (Ansible)

We need to define what "secure" looks like in code. We will use Ansible because it is agentless and readable. We aren't just installing software; we are stripping the OS down.

Here is a battle-tested Ansible snippet targeting a CentOS 8 or Ubuntu 18.04 LTS server. This playbook enforces SSH hardening—one of the first things an auditor checks.

- name: HARDEN SSH CONFIGURATION
  hosts: all
  become: yes
  tasks:
    - name: Ensure SSH Protocol is set to 2
      lineinfile:
        path: /etc/ssh/sshd_config
        regexp: '^Protocol'
        line: 'Protocol 2'
        state: present

    - name: Disable Root Login completely
      lineinfile:
        path: /etc/ssh/sshd_config
        regexp: '^PermitRootLogin'
        line: 'PermitRootLogin no'
        state: present

    - name: Disable Password Authentication (Keys Only)
      lineinfile:
        path: /etc/ssh/sshd_config
        regexp: '^PasswordAuthentication'
        line: 'PasswordAuthentication no'
        state: present

    - name: Enforce Max Auth Tries
      lineinfile:
        path: /etc/ssh/sshd_config
        regexp: '^MaxAuthTries'
        line: 'MaxAuthTries 3'
        state: present
      notify: restart_sshd

  handlers:
    - name: restart_sshd
      service:
        name: sshd
        state: restarted

This isn't just about configuration; it's about state enforcement. If a junior dev manually changes PermitRootLogin to yes to debug something, the next Ansible run reverts it immediately. That is compliance.

Network Stack Hardening

Next, we mitigate common denial-of-service vectors. While CoolVDS provides upstream ddos protection, your host must handle what gets through. We adjust the kernel directly (possible because we are on KVM).

- name: KERNEL HARDENING via SYSCTL
  sysctl:
    name: "{{ item.key }}"
    value: "{{ item.value }}"
    state: present
    reload: yes
  loop:
    - { key: 'net.ipv4.conf.all.accept_redirects', value: '0' }
    - { key: 'net.ipv4.conf.default.accept_redirects', value: '0' }
    - { key: 'net.ipv4.conf.all.secure_redirects', value: '0' }
    - { key: 'net.ipv4.icmp_echo_ignore_broadcasts', value: '1' }
    # Mitigate SYN floods
    - { key: 'net.ipv4.tcp_syncookies', value: '1' }
    - { key: 'net.ipv4.tcp_max_syn_backlog', value: '2048' }

Step 2: The Verification Layer (OpenSCAP)

How do you prove to an auditor that the above scripts worked? You use OpenSCAP (Security Content Automation Protocol). It compares your system against the CIS (Center for Internet Security) benchmarks.

First, install the scanner on your CoolVDS instance:

# For CentOS/RHEL
yum install openscap-scanner scap-security-guide

# For Ubuntu/Debian
apt-get install libopenscap8 ss

Now, run a scan against the standard profile. This command generates an HTML report you can literally hand to a GDPR auditor.

oscap xccdf eval \
  --profile xccdf_org.ssgproject.content_profile_pci-dss \
  --results scan-results.xml \
  --report report.html \
  /usr/share/xml/scap/ssg/content/ssg-rhel7-ds.xml

The resulting report.html will highlight every failure in red. In 2020, relying on "I think I secured it" is professional negligence. Tools like OpenSCAP provide the mathematical proof.

Data Sovereignty and Latency

Technical hardening is useless if the legal jurisdiction is flawed. With the European Court of Justice scrutinizing data transfers to the US (C-311/18), hosting sensitive customer data on US-owned hyperscalers is a gamble.

Hosting locally in Norway offers two distinct advantages:

For a Norwegian business, low latency isn't just about speed; it's about the user experience. A round trip to Frankfurt for every database query adds up. By keeping data in Oslo, you align with GDPR data minimization principles and ensure maximum performance.

Automated Updates: The Silent Killer

The most hardened server is vulnerable if it misses a patch. In May 2020, we are seeing a rise in automated botnets scanning for unpatched Nginx vulnerabilities. On a production system, you might fear auto-updates breaking things. This is where the "Cattle, not Pets" mentality applies.

Configure unattended-upgrades to handle security patches only.

// /etc/apt/apt.conf.d/50unattended-upgrades
Unattended-Upgrade::Allowed-Origins {
        "${distro_id}:${distro_codename}";
        "${distro_id}:${distro_codename}-security";
        // "${distro_id}:${distro_codename}-updates"; // Optional, riskier
};

Unattended-Upgrade::Automatic-Reboot "true";
Unattended-Upgrade::Automatic-Reboot-Time "04:00";

Combine this with a highly available setup (Load Balancer + 2 Application Nodes). If Node A reboots at 4:00 AM, Node B handles the traffic. This architecture is trivial to deploy on CoolVDS due to our competitive pricing model—running two smaller nodes often costs the same as one large node elsewhere.

Conclusion: Sleep Better

Compliance is not about checking boxes; it is about sleep assurance. Knowing that Ansible will reset a rogue configuration, that OpenSCAP will catch a missed vulnerability, and that your data sits on compliant hardware in Oslo allows you to focus on shipping code, not reading legal briefs.

Don't let your infrastructure become a legal liability. Start with a clean slate.
