TYPO3 Security and Maintenance: Updates, Extensions, & GDPR
Every website has a story to tell, and every story needs a secure place to be told. Although TYPO3 is a reliable content management system that aids businesses in creating engaging websites, even the best-designed websites can be at risk in the absence of proper security.
TYPO3 publishes a series of security advisories every year, ranging from minor errors to serious security vulnerabilities that, if ignored, could expose private information or disrupt business operations (typo3.org). The dangers are not limited to technical issues.
In addition to disrupting business operations and affecting customer trust, data breaches can also result in fines under laws such as the GDPR. The risks are significantly higher for companies that process personal data.
To protect website owners, TYPO3 offers configurations, tools, and advice. Let's work on protecting and securing your TYPO3 website!
TYPO3 Security Basics
The security of your TYPO3 website begins with understanding the system's core security features and best practices.
TYPO3 Core Security
TYPO3 caters to both small businesses and large enterprises. Since several TYPO3 websites contain sensitive information, security is particularly important.
The TYPO3 Security Team is responsible for monitoring the system for vulnerabilities and publishing official security advisories. Security advisories provide developers and website owners with guidelines to quickly address vulnerabilities and ensure a secure environment.
Security Updates and Advisories
The TYPO3 Security Team releases updates as soon as a vulnerability is discovered. The updates include instructions for patching the core system, and the advisories contain recommendations for security practices. Following the advisories protects a website from known vulnerabilities.
Long-Term Support (LTS) and Extended LTS (ELTS)
The LTS version of TYPO3 receives regular security updates over several years. The Extended LTS (ELTS) provides additional support for organizations that cannot immediately upgrade to a newer version.
Using supported versions is necessary because unsupported versions no longer receive patches. Attackers exploit insecure and unsupported websites.
Security Updates and Patch Management
Updating TYPO3 is crucial for the security of the website. Updates fix security vulnerabilities, improve stability, and ensure that the website meets security standards.
How TYPO3 Releases Security Updates
The TYPO3 Security Team analyzes the core system and extensions for security vulnerabilities. When a vulnerability is found, an official advisory is published on how the system can be patched, usually classified by severity.
Comparison Chart: LTS vs ELTS vs Unsupported
Version | Updates | Support | Cost | Recommendation |
LTS | Regular | Community + Security Team | Free | Recommended for most sites |
ELTS | Regular | Paid extended support | Paid | For sites that cannot upgrade |
Unsupported | None | None | N/A | Avoid high risk |
Applying TYPO3 Security Updates
- Back up the website before the update
- Apply patches promptly, especially if they have a high severity rating
- Test updates in a staging environment before deploying them to production
- Regularly check TYPO3 security advisories
Risks of Skipping TYPO3 Security Updates
Running an outdated version of TYPO3 makes the website vulnerable to attacks, data breaches, as well as fines or downtime. Timely and consistent updates of TYPO3 are crucial to ensure that the website remains secure and reliable.
TYPO3 Extensions and Security
Extensions extend the functionality of TYPO3 websites, but improper use or lack of maintenance can also cause security issues.
TYPO3 Secure Extensions
TYPO3 provides documentation on secure extensions, which are also regularly maintained. It is important to choose extensions only from secure sources and to check the update history to minimize potential security vulnerabilities.
Some TYPO3 Extensions specifically focus on security, including:
- Secure Backend Password: Enforces strict password policies for all backend users.
- StaticFileCache: Improves website performance, security, and caching of static files.
- Backup Plus: Provides a backup solution, but can be insecure in certain versions.
How to Check TYPO3 Extension Security
One should ask the registrar to check the last update of the extension and review known secure extensions in the TYPO3 security advisories for potential issues. It is also recommended to test new extensions in a staging environment and in QA before deploying them to the production environment.
Auditing and Cleaning Up TYPO3 for Security
Regular audits or processes for extensions help identify unused or potentially risky extensions. Removing unnecessary extensions reduces the attack surface and ensures that the website runs more stably and securely.
TYPO3 Security and GDPR Compliance
The security of websites is crucial for protecting public data, especially in light of the strict German regulations on website access and data protection according to the GDPR. TYPO3 offers the ability to meet both technical and legal requirements, particularly the secure processing of personal data after consent has been given.
Legal Compliance
Disregarding the GDPR requirements can lead to high fines or other legal consequences. With TYPO3's functionality, organizations can systematically build data protection-compliant features, thereby reducing the risk of fines or issues with GDPR compliance obligations.
Data Protection Features
TYPO3 has numerous integrated and optional features to protect user data:
- Role-based access control: Ensures that only authorized users have access to confidential data.
- Encryption: SSL/TLS connections for secure data transmission as well as security headers that ensure secure browser connections against hacker attacks.
- Consent Management: Tools for managing user consents, including the anonymization of IP addresses and opt-in/opt-out mechanisms.
- Logging & Monitoring: Shows which users have accessed data and highlights potential security risks to promote transparency and accountability.
Risks of Non-Compliance
Without an adequate level of security and GDPR compliance, there is a risk of fines, business restrictions, reputational damage, or loss of customers.
TYPO3 Security Best Practices
This includes far more than just updates and extensions; it helps ensure that your website is protected.
Passwords and Access
- Use strong and unique passwords for all users.
- Limit user access to what is necessary.
- Use two-factor authentication (2FA) for additional protection.
Server and Hosting
- Use SSL/TLS to encrypt data between the website and users.
- Choose a hosting provider with experience in TYPO3 CMS and security issues.
- Deploy firewalls to fend off unwanted traffic.
Backups and Recovery
- Regularly back up your website and database.
- Store backups in a secure and separate location.
- Test the recovery of backups to ensure they work in an emergency.
Logging and Monitoring
- Keep logs of user interactions and system events.
- Monitor access logs for suspicious files or activities.
- Use notifications for security-related incidents.
Security Checks

Following these procedures will help make your TYPO3 website stronger and more dependable.
TYPO3 Maintenance and Security Services
