Automating Security Compliance: A DevOps Guide to Surviving GDPR & CIS Benchmarks in Norway

If you treat security compliance as a quarterly manual checklist, you have already lost. In the current threat environment, a server that was secure on Monday is a liability by Friday. I learned this the hard way back in 2019 when a manual configuration drift on a database cluster led to a minor, yet embarrassing, exposure during a penetration test. We spent three days manually patching sshd_config files across 50 nodes. Never again.

For systems architects operating in Europe—and specifically Norway—the stakes are financial and legal. With the Schrems II ruling invalidating the Privacy Shield, moving data outside the EEA is a legal minefield. If your infrastructure isn't strictly controlled, automated, and legally domiciled, Datatilsynet (The Norwegian Data Protection Authority) will not be lenient.

This guide cuts through the noise. We aren't talking about theoretical frameworks. We are talking about using Ansible and OpenSCAP to enforce CIS Benchmarks on a CoolVDS NVMe instance, ensuring your infrastructure is hardened by code, not luck.

The "Data Sovereignty" Foundation

Before touching a single config file, look at your infrastructure provider. You cannot code your way out of a bad jurisdiction. Many "cloud" providers abstract the physical location of your data. For a compliance audit, that ambiguity is a fail.

We use CoolVDS for high-compliance workloads for two specific reasons:

1. KVM Virtualization: Unlike OpenVZ or LXC containers, KVM provides a true hardware virtualization layer. There is no shared kernel with the host. This isolation is often a strict requirement for PCI-DSS and specialized health data compliance.
2. Norwegian Jurisdiction: Data residing physically in Oslo, protected by Norwegian privacy laws, simplifies the GDPR compliance matrix significantly compared to US-owned hyperscalers.

Step 1: Hardening the Base Image (The Manual Verification)

While we will automate this, you must understand what you are changing. A standard Linux install is designed for compatibility, not security. It listens on too many ports and allows too many protocols.

On a fresh Debian 11 or Ubuntu 22.04 node, your network stack needs immediate tightening to prevent man-in-the-middle attacks and IP spoofing.

Verify your /etc/sysctl.conf includes these directives. If they aren't there, your server is happy to redirect traffic where it shouldn't.

# IP Spoofing protection
net.ipv4.conf.all.rp_filter = 1
net.ipv4.conf.default.rp_filter = 1

# Ignore ICMP broadcast requests
net.ipv4.icmp_echo_ignore_broadcasts = 1

# Disable source packet routing
net.ipv4.conf.all.accept_source_route = 0
net.ipv6.conf.all.accept_source_route = 0

# Disable send redirects
net.ipv4.conf.all.send_redirects = 0
net.ipv4.conf.default.send_redirects = 0

Apply these with sysctl -p. If you are running on CoolVDS, you'll notice the network stack reloads instantly—the low latency to the NIX (Norwegian Internet Exchange) ensures your management connections don't hang during network restarts.

Step 2: Automating CIS Benchmarks with OpenSCAP

The Center for Internet Security (CIS) provides the gold standard for server hardening. Checking these manually involves over 200 steps. That is not scalable.

Enter OpenSCAP. It scans your system against the SCAP Security Guide (SSG) and reports failures. Here is how to install it on a Red Hat/CentOS stream or Fedora based system (common in enterprise environments):

sudo dnf install openscap-scanner scap-security-guide

To run a compliance scan against the CIS Level 2 Server profile (the strict one):

oscap xccdf eval \
 --profile xccdf_org.ssgproject.content_profile_cis_server_l2 \
 --results scan-results.xml \
 --report scan-report.html \
 /usr/share/xml/scap/ssg/content/ssg-rhel9-ds.xml

This command generates an HTML report showing exactly where you fail. On a standard VPS from most providers, you will fail about 40% of checks immediately. On a CoolVDS instance, because you have full root control via KVM, you can fix all of them. You aren't blocked by a restricted kernel.

Step 3: Remediation with Ansible

Scanning is observation; Ansible is action. Do not fix the report manually. Write a playbook. This ensures that if you deploy ten more nodes next week to handle a traffic spike, they are compliant at boot.

Here is a snippet of a "Hardening" role that addresses common SSH failures found in the OpenSCAP report:

---
- name: Secure SSH Configuration
  hosts: all
  become: yes
  tasks:
    - name: Disable Root Login
      lineinfile:
        path: /etc/ssh/sshd_config
        regexp: '^PermitRootLogin'
        line: 'PermitRootLogin no'
        state: present
      notify: restart_sshd

    - name: Disable Password Authentication
      lineinfile:
        path: /etc/ssh/sshd_config
        regexp: '^PasswordAuthentication'
        line: 'PasswordAuthentication no'
        state: present
      notify: restart_sshd

    - name: Set Idle Timeout Interval
      lineinfile:
        path: /etc/ssh/sshd_config
        regexp: '^ClientAliveInterval'
        line: 'ClientAliveInterval 300'
        state: present
      notify: restart_sshd

    - name: Limit SSH Access to Specific Users
      lineinfile:
        path: /etc/ssh/sshd_config
        line: 'AllowUsers deploy_user ansible_admin'
        state: present
      notify: restart_sshd

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

Pro Tip: Always run your Ansible playbooks with --check first. I once locked myself out of a remote server in Trondheim because I disabled password auth before successfully copying my SSH key. Latency matters, but having access matters more. If you do lock yourself out, the CoolVDS VNC console is your fallback to regain access via the virtual TTY.

The Trade-off: Security vs. Usability

Hardening is a balancing act. If you apply the full STIG or CIS Level 2 profile blindly, you might break your application.

Why Infrastructure Choice Dictates Compliance

You can script all the security in the world, but if your neighbor on the physical host is noisy or malicious, your availability—a key pillar of the CIA triad (Confidentiality, Integrity, Availability)—is compromised.

Shared hosting or weak containerization (OpenVZ) allows for "resource stealing." In a compliance audit, being unable to guarantee CPU cycles during a DDoS attack is a failure. CoolVDS isolates resources using KVM. Your NVMe I/O is yours. Your RAM is yours. This deterministic performance is critical when your logs are being hammered by auditd during a forensic analysis.

Final Thoughts

Compliance is not about passing an audit once a year. It is about sleeping at night knowing that your Ansible cron jobs are enforcing policy every 24 hours. It's about knowing your data sits in a facility in Norway, protected by local laws, on hardware that doesn't buckle under load.

Don't wait for the letter from Datatilsynet. Audit your infrastructure today.
