Automating Security Compliance: Surviving Datatilsynet Audits with Code

If you are still managing your infrastructure compliance using Excel spreadsheets and manual checklists, you are already non-compliant. By the time you finish checking box 42 regarding SSH root login, a developer has likely pushed a container with a critical CVE to production.

In the Norwegian market, the stakes are higher. Datatilsynet (The Norwegian Data Protection Authority) has become increasingly aggressive with fines post-2023, and the implementation of the EU AI Act has added another layer of regulatory complexity. For a CTO or System Architect operating in 2025, "hope" is not a strategy. You need a pipeline that rejects non-compliant infrastructure before it ever sees live traffic.

We are going to dismantle the old way of doing things. Here is how to build a self-healing, self-auditing infrastructure stack using Ansible, OpenSCAP, and strictly sovereign Norwegian infrastructure.

The Myth of the "Secure" Cloud Provider

Many providers claim to be "GDPR compliant." This is marketing fluff. A provider can offer a compliant facility (ISO 27001, biometric access, N+1 power), but they cannot make your implementation compliant. This is the Shared Responsibility Model.

The CoolVDS Reality Check: We provide the bedrock. Our data centers in Oslo ensure your data never physically leaves Norwegian jurisdiction, solving the Schrems II / Data Privacy Framework headaches instantly. We guarantee the physical security and network perimeter (DDoS protection). You own the OS and the application logic. If you leave port 22 open to the world on a CoolVDS NVMe instance, that is on you.

Step 1: Hardening at the Source (Infrastructure as Code)

Compliance begins with the first line of code. We do not manually configure servers via SSH anymore. We describe the desired state.

Let's look at a practical example using Ansible to enforce a CIS (Center for Internet Security) Level 1 benchmark on an Ubuntu 24.04 LTS server. This playbook ensures that common attack vectors are closed automatically upon provisioning.

The `hardening.yml` Playbook

---
- name: Harden Ubuntu 24.04 LTS for GDPR Compliance
  hosts: coolvds_instances
  become: yes
  tasks:
    - name: Ensure SSH root login is disabled
      lineinfile:
        path: /etc/ssh/sshd_config
        regexp: '^PermitRootLogin'
        line: 'PermitRootLogin no'
        state: present
      notify: Restart SSH

    - name: Enforce password complexity (pam_pwquality)
      apt:
        name: libpam-pwquality
        state: present

    - name: Set password quality requirements
      lineinfile:
        path: /etc/security/pwquality.conf
        regexp: '^{{ item.key }}'
        line: '{{ item.key }} = {{ item.value }}'
      loop:
        - { key: 'minlen', value: '14' }
        - { key: 'dcredit', value: '-1' }
        - { key: 'ucredit', value: '-1' }
        - { key: 'ocredit', value: '-1' }
        - { key: 'lcredit', value: '-1' }

    - name: Disable unused filesystems (CIS 1.1.1)
      modprobe:
        name: "{{ item }}"
        state: absent
      loop:
        - cramfs
        - freevxfs
        - jffs2
        - hfs
        - hfsplus

  handlers:
    - name: Restart SSH
      service:
        name: ssh
        state: restarted

This is not just configuration; it is documentation. When an auditor asks how you handle password complexity, you do not show them a policy PDF nobody reads. You show them this Git repository.

Step 2: Network Segregation & Firewalling

Latency matters. Routing traffic through a firewall appliance in Frankfurt when your users are in Bergen is inefficient. Use the host-level firewall (`ufw` or `nftables`) to handle immediate threats at the edge.

On a high-performance CoolVDS instance, the NVMe storage I/O is fast enough that heavy logging from firewall drops won't degrade your database performance. Here is the standard `ufw` setup we deploy for web nodes:

# Reset to default deny incoming, allow outgoing
ufw default deny incoming
ufw default allow outgoing

# Allow SSH only from your specific VPN IP (Critical for admins)
ufw allow from 192.0.2.50 to any port 22 proto tcp

# Allow HTTP/HTTPS
ufw allow 80/tcp
ufw allow 443/tcp

# Enable logging (Essential for forensics)
ufw logging on
ufw enable

Step 3: Continuous Auditing with OpenSCAP

Configuration drift is the enemy. A sysadmin logs in at 3 AM to fix a bug, temporarily disables a security flag, and forgets to re-enable it. Two weeks later, you are vulnerable.

In 2025, we use OpenSCAP to run automated scans against our infrastructure. This tool compares your current system state against the XCCDF (Extensible Configuration Checklist Description Format) profiles.

Here is how you install and run a compliance scan on your server:

sudo apt-get update && sudo apt-get install libopenscap8 ssf-guides -y

# List available profiles for Ubuntu 24.04
oscap info /usr/share/xml/scap/ssg/content/ssg-ubuntu2404-ds.xml

# Run a scan against the standard CIS Level 1 profile
oscap xccdf eval \
  --profile xccdf_org.ssgproject.content_profile_cis_level1_server \
  --results /var/log/oscap-results.xml \
  --report /var/www/html/security-report.html \
  /usr/share/xml/scap/ssg/content/ssg-ubuntu2404-ds.xml

This generates an HTML report showing exactly where you pass and fail. Automate this with a cron job and ship the logs to a central server.

Step 4: The Database Layer

Your database is the crown jewel. Whether you are running MariaDB or PostgreSQL, default configurations are designed for compatibility, not security. For a CoolVDS instance with 32GB RAM, you need to tune the buffer pool for performance, but you must also force encryption.

In `my.cnf` (for MySQL/MariaDB), ensure data is encrypted at rest and in transit:

[mysqld]
# Force TLS version 1.3 (Standard in 2025)
tls_version=TLSv1.3
require_secure_transport=ON

# Data-at-rest encryption
plugin_load_add = file_key_management
file_key_management_filename = /etc/mysql/encryption/keyfile.enc
file_key_management_encryption_algorithm = AES_CTR
innodb_encrypt_tables = ON
innodb_encrypt_log = ON

# Performance tuning for CoolVDS NVMe
innodb_io_capacity = 2000
innodb_io_capacity_max = 4000
innodb_flush_method = O_DIRECT

Why Infrastructure Choice Dictates Compliance

You can script `iptables` all day, but if your host over-provisions CPU or stores backups on a drive accessible by other tenants, your logical security is moot. This is where the "noisy neighbor" problem becomes a security risk—Sidechannel attacks are rare but real.

CoolVDS uses KVM (Kernel-based Virtual Machine) virtualization. Unlike container-based VPS (LXC/OpenVZ) where the kernel is shared, KVM provides hardware-level isolation. Your memory is your memory. Your CPU instructions are yours.

The Local Edge: Norway and NIX

If your target audience is in Scandinavia, routing traffic through US-owned hyperscalers adds 20-30ms of latency and a mountain of legal paperwork regarding data transfer mechanisms. Hosting directly on the Norwegian Internet Exchange (NIX) via CoolVDS reduces latency to sub-5ms for local users. Speed is a security feature—it mitigates DDoS impact and accelerates Tls handshakes.

Final Thoughts

Compliance is not a state; it is a continuous loop. The regulations in 2025 demand proof of ongoing vigilance, not a one-time stamp.

1. Define infrastructure as code (Ansible/Terraform).
2. Harden the OS immediately upon boot.
3. Audit continuously with OpenSCAP.
4. Host on isolated, sovereign infrastructure.

Don't let a compliance audit slow down your deployment velocity. Build the guardrails, automate the checks, and deploy with confidence.
