What can TYPO3 do?

TYPO3 is a powerful and secure CMS, especially suited for complex enterprise solutions.
It is based on PHP, is open source, and therefore available free of license costs for private as well as commercial use. TYPO3 is one of the leading CMS platforms worldwide and is used primarily for complex and extensive web projects such as corporate portals, intranets, and e-commerce applications.

What makes TYPO3 stand out?

• Multilingual support and SEO optimization: TYPO3 offers integrated features for multilingual websites and search engine optimization.
• User role management: With role-based access control (RBAC), access permissions can be defined individually.
• Time-controlled content: Content can be published or deactivated automatically at specific times.

TYPO3 compared to other CMS

1. Compared with WordPress
2. • Less beginner-friendly, but significantly more comprehensive for complex projects.
3. Compared with Drupal
4. • Clearer tree structure for content organization.
   • Higher stability in large projects.

When should TYPO3 be used?

• Large companies: TYPO3 is particularly well suited for extensive content requirements or international projects.
• Multilingual websites: Supports more than 50 languages in the backend.
• Security-critical applications: Strict security standards and regular updates make TYPO3 a good choice for data protection and high security requirements.
• Individual requirements: TypoScript enables dynamic content and custom layouts. With over 6,000 available extensions and the ability to develop your own modules, TYPO3 is almost infinitely customizable.

Is TYPO3 accessible?

TYPO3 promotes accessibility in both the frontend and backend. It supports the creation of accessible websites in accordance with international standards (e.g. WCAG). However, for editors, getting started with the backend can be somewhat more challenging than with more user-friendly systems like WordPress.

What types of extensions does TYPO3 offer?

• SEO: Tools for optimizing URLs, metadata, and rankings.
• E-commerce: Extensions for online shops.
• Integration of external systems: Connections to ERP, CRM, or PIM systems.
• Content extensions: Modules for forms, galleries, or blogs.
• Performance: Various caching solutions to speed up loading times.

The extensions undergo thorough review and integrate seamlessly into the TYPO3 system. This allows companies to design their websites individually while managing them efficiently.

Innovations in TYPO3 Version 13

• Improved user-friendliness: Optimized backend for editors.
• Updated technologies: Support for modern web technologies such as PHP 8.x and current database standards.
• Expanded security features: Stricter security measures for the core and extensions.

5. Two-factor authentication (2FA) and multi-factor authentication (MFA)
6. • Additional layer of security for logins.
   • Even if a password is compromised, access remains protected by an additional factor.
7. Protection against XSS and SQL injections
8. • Integrated mechanisms in the core prevent the most common attack techniques.
   • Extensions must meet strict security standards.
9. HTTPS/TLS support
10. • Secure data transmission between server and user.
    • Encryption prevents interception of sensitive information.
11. Extension security
12. • Official extensions are thoroughly reviewed.
    • An integrated extension scanner detects potential security vulnerabilities.
13. IP whitelisting
14. • Access to the backend can be restricted to trusted IP addresses.
    • Reduces the risk of unauthorized logins from unknown locations.
15. Monitoring and backups
16. • Logging of access and errors for early detection of suspicious activity.
    • Regular backups protect against data loss in the event of attacks or system failures.
17. Data protection compliance
18. • “Protected Storages” store files outside the virtual host.
    • Facilitates compliance with data protection regulations such as the GDPR.
19. Active developer community.

Thanks to these comprehensive security measures, TYPO3 is particularly suitable for companies with high requirements for data protection and security. The regular updates and the active community make a major contribution to the security of TYPO3.

Role-based access control (RBAC) in TYPO3

The RBAC system controls access to backend resources and functions based on defined user roles:

1. Definition of user roles
2. • Roles such as administrator, editor, or guest are created through user groups.
3. Assignment of permissions
4. • Each role receives specific rights (e.g. access to modules, editing or deleting content).
5. Assignment of users to roles
6. • Users can belong to one or more roles at the same time.
7. Hierarchical structure
8. • Global, page-based, or module-based permissions enable fine-grained assignment of rights.
9. Access control in the backend
10. • Users only see the areas they are actually allowed to access.
11. Extensibility through extensions
12. • Developers can add custom roles and permissions.

Advantages of RBAC

• Efficiency: Centralized management of rights and roles.
• Security: Minimization of unauthorized access.
• Flexibility: Diverse combinations of roles possible.
• Traceability: Changes to roles/permissions are auditable.

Protection against Cross-Site Request Forgery (CSRF) in TYPO3

TYPO3 uses several mechanisms to defend against CSRF attacks:

1. Token-based CSRF protection
2. • For each form, a unique token is generated and validated.
   • Invalid or missing tokens are rejected.
3. SameSite cookie attribute
4. • Prevents cookies from being sent with cross-site requests.
   • Configuration via BE/cookieSameSite.
5. Referrer header validation
6. • Via the setting security.backend.enforceReferrerchecks the referrer in TYPO3.
   • Protects against requests that do not originate from its own domain environment.
7. HTTP method check
8. • State-changing actions may only take place via POST.
   • Incorrect method calls are blocked.
9. Regular updates and best practices
10. • The TYPO3 Security Team promptly releases patches.
    • Extensions such as the Secure Web Package additionally increase security.
    • HTTPS/TLS is supported for encrypting data transmission.

By combining these security mechanisms (CSRF tokens, SameSite cookies, referrer validation), TYPO3 remains highly resistant to CSRF attacks.

All in all

Thanks to extensive features such as multilingual support, flexibility through TypoScript, role-based access control, and strict security standards, it meets high requirements for data protection and performance. The active developer community ensures regular updates and quick responses to security vulnerabilities.

With version 13, TYPO3 has received additional improvements in terms of user-friendliness, technology updates, and performance. The CMS therefore remains a leading choice in the enterprise sector and is particularly suitable where security, stability, and customizability are paramount.
