Lab 20: Capstone — Enterprise Hardened HA Server

Time: 45 minutes | Level: Architect | Docker: docker run -it --rm --privileged ubuntu:22.04 bash

Overview

This capstone synthesises all four Architect tracks into a complete enterprise hardening + HA blueprint. You will: audit CIS Level 2 compliance with Lynis, write an Ansible playbook to enforce all hardening controls, configure Prometheus + Alertmanager monitoring stubs, design a Pacemaker/HAProxy HA configuration, set up a LUKS-encrypted data volume, enforce AppArmor mandatory access control, configure comprehensive auditd rules and AIDE integrity monitoring, and produce a final JSON compliance report that scores all controls. This is the definitive Architect competency check.

Step 1 — CIS Level 2 Baseline Audit

apt-get update -qq && apt-get install -y -qq lynis aide 2>/dev/null

echo "=== Lynis Version ==="
lynis --version

echo ""
echo "=== CIS Level 2 Baseline Scan ==="
lynis audit system --quick --no-colors --skip-plugins 2>&1 | \
  grep -E "(Hardening index|Tests performed|WARNING|Suggestion)" | head -20

📸 Verified Output:

=== Lynis Version ===
3.0.7

=== CIS Level 2 Baseline Scan ===
  Hardening index : 60 [############        ]
  Tests performed : 221

# Get top hardening suggestions
lynis audit system --quick --no-colors --skip-plugins 2>&1 | \
  grep "Suggestion" | head -15

📸 Verified Output:

  Suggestion: Install a PAM module for password strength testing [AUTH-9262]
  Suggestion: Configure minimum password age in /etc/login.defs [AUTH-9286]
  Suggestion: Configure maximum password age in /etc/login.defs [AUTH-9286]
  Suggestion: Default umask in /etc/profile or /etc/profile.d/custom.sh could be more strict [AUTH-9328]
  Suggestion: To decrease the impact of a full /home file system, place /home on a separate partition [FILE-6310]
  Suggestion: To decrease the impact of a full /tmp file system, place /tmp on a separate partition [FILE-6310]
  Suggestion: Disable drivers like USB storage when not used [STRG-1840]
  Suggestion: Check DNS configuration for the dns domain [NAME-4028]
  Suggestion: Add a legal banner to /etc/issue, to warn unauthorized users [BANN-7126]
  Suggestion: Add legal banner to /etc/issue.net [BANN-7128]
  Suggestion: Enable sysstat to collect accounting (disabled) [ACCT-9626]
  Suggestion: Enable process accounting [ACCT-9622]
  Suggestion: Install debsums utility for the verification of packages with known good database [PKGS-7370]

💡 Tip: CIS Level 2 target is Lynis hardening index ≥ 80. The gap from 60 to 80+ requires applying SSH hardening, PAM configuration, audit rules, and AppArmor enforcement.

Step 2 — Ansible Hardening Playbook

Build the Ansible playbook that enforces all CIS Level 2 controls:

apt-get install -y -qq ansible 2>/dev/null || \
  pip3 install ansible 2>/dev/null || \
  echo "Ansible install simulated"

mkdir -p /opt/hardening/{roles/cis_hardening/{tasks,handlers,templates,files},inventory}
