<h2>Why Odoo Security Matters More Than Ever</h2>
<p>Your Odoo ERP system contains your business's most sensitive information: customer data, financial records, employee information, trade secrets, and proprietary processes. A security breach can result in:</p>
<ul>
<li>💰 <strong>Financial losses:</strong> Average cost of a data breach in Australia is $4.35 million (IBM 2024)</li>
<li>⚖️ <strong>Legal penalties:</strong> Australian Privacy Principles violations can cost millions</li>
<li>📉 <strong>Reputation damage:</strong> Loss of customer trust and business opportunities</li>
<li>⏸️ <strong>Business disruption:</strong> Ransomware can halt operations for weeks</li>
</ul>
<p>This guide provides actionable security best practices specifically for Odoo implementations in 2025.</p>
<h2>1. Secure Hosting Configuration</h2>
<h3>Choose the Right Hosting Environment</h3>
<p><strong>Cloud Hosting (Recommended for Most):</strong></p>
<ul>
<li><strong>Odoo.sh:</strong> Managed security, automatic updates, built-in backups</li>
<li><strong>AWS/Azure:</strong> Enterprise-grade security, compliance certifications</li>
<li><strong>Reputable VPS:</strong> DigitalOcean, Linode with proper hardening</li>
</ul>
<p><strong>On-Premise Hosting:</strong></p>
<ul>
<li>Full control but requires dedicated IT security expertise</li>
<li>Physical security of servers</li>
<li>Network security management</li>
<li>Regular security patching responsibility</li>
</ul>
<h3>Essential Server Security Measures</h3>
<p><strong>✅ SSL/TLS Certificate (HTTPS):</strong></p>
<ul>
<li>Mandatory: Encrypt all data in transit</li>
<li>Use Let's Encrypt for free, automatic certificates</li>
<li>Enforce HTTPS redirects (no HTTP access)</li>
<li>Enable HTTP Strict Transport Security (HSTS)</li>
</ul>
<p><strong>✅ Firewall Configuration:</strong></p>
<ul>
<li>Block all ports except 80 (HTTP redirect) and 443 (HTTPS)</li>
<li>Whitelist IP addresses for SSH access (port 22)</li>
<li>Use fail2ban to block brute-force attempts</li>
<li>Consider Web Application Firewall (WAF) like Cloudflare</li>
</ul>
<p><strong>✅ Regular Security Updates:</strong></p>
<ul>
<li>Enable automatic security updates for OS</li>
<li>Update Odoo to latest stable version quarterly</li>
<li>Monitor security advisories from Odoo S.A.</li>
<li>Patch critical vulnerabilities within 48 hours</li>
</ul>
<h2>2. Access Control and Authentication</h2>
<h3>Strong Password Policies</h3>
<p><strong>Enforce Password Requirements:</strong></p>
<ul>
<li>Minimum 12 characters (16+ recommended)</li>
<li>Mix of uppercase, lowercase, numbers, symbols</li>
<li>No common words or patterns</li>
<li>Password expiry every 90 days for admin accounts</li>
<li>Prevent password reuse (last 5 passwords)</li>
</ul>
<p><strong>Configuration in Odoo:</strong></p>
<pre><code># In odoo.conf
[options]
password_policy = true
password_minimum_length = 12
</code></pre>
<h3>Two-Factor Authentication (2FA)</h3>
<p><strong>2FA is CRITICAL for:</strong></p>
<ul>
<li>All administrator accounts</li>
<li>Finance/accounting users</li>
<li>Users with sensitive data access</li>
<li>Remote/external consultants</li>
</ul>
<p><strong>How to Enable in Odoo:</strong></p>
<ol>
<li>Go to Settings → Users & Companies → Users</li>
<li>Edit user → Enable "Two-Factor Authentication"</li>
<li>User scans QR code with Google Authenticator/Authy</li>
<li>Requires code at each login</li>
</ol>
<h3>Role-Based Access Control (RBAC)</h3>
<p><strong>Principle of Least Privilege:</strong></p>
<p>Users should only have access to data they need for their job.</p>
<p><strong>Best Practices:</strong></p>
<ul>
<li>✅ Create custom user groups (e.g., "Sales Team", "Finance", "Warehouse")</li>
<li>✅ Assign specific module access per group</li>
<li>✅ Restrict "Settings" access to IT admins only</li>
<li>✅ Limit "Delete" permissions</li>
<li>✅ Use record rules to restrict data visibility (e.g., salespeople see only their customers)</li>
</ul>
<p><strong>Dangerous Permissions to Restrict:</strong></p>
<ul>
<li>🚨 Settings → Full admin access</li>
<li>🚨 Accounting → Delete posted entries</li>
<li>🚨 Inventory → Bypass validation workflows</li>
<li>🚨 Developer Mode → Code execution</li>
</ul>
<h2>3. Database Security</h2>
<h3>PostgreSQL Hardening</h3>
<p><strong>Essential PostgreSQL Security:</strong></p>
<ul>
<li>Never expose PostgreSQL port (5432) to internet</li>
<li>Use strong database passwords (20+ characters)</li>
<li>Enable SSL connections for database</li>
<li>Restrict database user permissions</li>
<li>Regular database vacuum and maintenance</li>
</ul>
<p><strong>Database Encryption:</strong></p>
<ul>
<li><strong>Encryption at rest:</strong> Use encrypted storage volumes</li>
<li><strong>Encryption in transit:</strong> SSL between Odoo and PostgreSQL</li>
<li><strong>Backup encryption:</strong> Encrypt all backup files</li>
</ul>
<h3>Database Backup Strategy</h3>
<p><strong>The 3-2-1 Backup Rule:</strong></p>
<ul>
<li><strong>3 copies:</strong> Production + 2 backups</li>
<li><strong>2 media types:</strong> Local disk + cloud storage</li>
<li><strong>1 offsite:</strong> Geographic redundancy</li>
</ul>
<p><strong>Backup Frequency:</strong></p>
<ul>
<li><strong>Daily:</strong> Full database backups (automated)</li>
<li><strong>Hourly:</strong> Transaction log backups (critical systems)</li>
<li><strong>Monthly:</strong> Long-term archives</li>
</ul>
<p><strong>Test Backup Restoration:</strong></p>
<ul>
<li>Monthly restore tests to staging environment</li>
<li>Verify data integrity and completeness</li>
<li>Document restoration procedures</li>
<li>Measure Recovery Time Objective (RTO)</li>
</ul>
<h2>4. Application-Level Security</h2>
<h3>Odoo Configuration Hardening</h3>
<p><strong>Critical odoo.conf Settings:</strong></p>
<pre><code>[options]
# Disable database manager web interface
list_db = False
db_name = your_production_db
# Restrict database operations
dbfilter = ^your_production_db$
# Limit request size (prevent DoS)
limit_request = 8196
limit_memory_hard = 2684354560
limit_memory_soft = 2147483648
limit_time_cpu = 600
limit_time_real = 1200
# Enable security features
proxy_mode = True
workers = 4
max_cron_threads = 2
</code></pre>
<h3>Secure API Access</h3>
<p><strong>If using external API integrations:</strong></p>
<ul>
<li>Use API keys, not user passwords</li>
<li>Create dedicated "API User" accounts with limited permissions</li>
<li>Implement rate limiting to prevent abuse</li>
<li>Log all API requests for audit trail</li>
<li>Use OAuth2 for third-party integrations</li>
<li>Whitelist IP addresses when possible</li>
</ul>
<h3>Session Management</h3>
<p><strong>Configure Session Security:</strong></p>
<ul>
<li>Short session timeouts (30-60 minutes of inactivity)</li>
<li>Force re-authentication for sensitive operations</li>
<li>Invalidate sessions on password change</li>
<li>Log out all sessions on security incident</li>
</ul>
<h2>5. Monitoring and Auditing</h2>
<h3>Enable Comprehensive Logging</h3>
<p><strong>Log Everything:</strong></p>
<ul>

<li>Permission changes</li>
<li>Database modifications</li>
<li>Export of sensitive data</li>
<li>Failed authorization attempts</li>
<li>System errors and warnings</li>
</ul>
<p><strong>Odoo Audit Trail Module:</strong></p>
<ul>
<li>Tracks all record modifications</li>
<li>Shows who, when, what changed</li>
<li>Essential for compliance (SOX, GDPR, APPs)</li>
<li>Enable for sensitive models (Invoices, Payments, HR records)</li>
</ul>
<h3>Security Monitoring Tools</h3>
<p><strong>Implement Monitoring:</strong></p>
<ul>
<li><strong>Uptime monitoring:</strong> UptimeRobot, Pingdom</li>
<li><strong>Log analysis:</strong> ELK Stack, Graylog</li>
