2025 is dedicated to the "Email Security Year" campaign by the German Federal Office for Information Security (BSI), in which eco is actively participating. The goal is to promote key security mechanisms such as SPF, DKIM, DMARC, DANE and DNSSEC and thereby sustainably secure email communication.

DNSSEC plays a key role in this: The Domain Name System (DNS) forms the foundation of almost all Internet services – from name resolution and email security to modern applications. Without DNSSEC, attacks such as phishing, spoofing or redirection to manipulated websites can bypass existing protective measures and undermine trust in Internet communication.

  • Email Security: Technologies like SPF, DKIM and DMARC rely on DNS entries to prevent phishing and spoofing. DNSSEC is a fundamental prerequisite for DANE.
  • Authentication: SSH fingerprints, certificates or cloud tokens are provided via DNS.
  • Network configuration: Client systems obtain important information for communication and connectivity via DNS.

Precisely because DNS is so central, it represents an attractive target for attacks. Without additional security mechanisms, DNS data can be forged or manipulated in transit. The consequences range from redirection to fake websites to the circumvention of established security mechanisms such as TLS certificates or same-origin policies in web applications.

Workshop objective: In cooperation with ICANN, this two-day workshop provides hands-on training on how DNSSEC works, how it can be implemented, and how it can be integrated into existing DNS infrastructures. In addition to the technical fundamentals, organisational aspects, best practices and the significance of DNSSEC in an international context will also be addressed.

Workshop content:
• Brief introduction / DNS summary
• Signing
• Validation
• Non-existence
• Key management
• Chain of Trust
• Policy Considerations
• Setting up validation in a Recursive Server
• Signing Zones (Authoritative Servers)
• DNSSEC operations and maintenance
• Tools: Troubleshooting and Monitoring

Labs:

• DNS/DNSSEC debugging
• Zone creation and configuration: primary and secondaries
• Zone signing: manual and automatic signing
• Establish and confirm chain of trust
• DNSSEC validation (recursive resolver)
