On December 2022, as part of the Digital Learning Hub's winter course, Restena raises awareness on DNS and trains all professionals wishing to secure their DNS infrastructure with the DNSSEC protocol.

Instructeur et apprenant aux formations DLH

On December 2022, Dr Guillaume-Jean Herbiet, .lu service technical manager, will once again speak to the Digital Learning Hub (DLH) students, a continuing professional education structure in Luxembourg.

A theoretical workshop introducing the Domain Name System (DNS) will complement a technical workshop - tried and tested during the previous course - dedicated to DNSSEC (Domain Name System Security Extensions) and its functioning. These two concepts are closely associated since implementing DNSSEC on the DNS infrastructure makes it possible to secure an online presence and ensure the security of domain names.


On 8 and 9 December 2022, within the ‘Introduction to the Domain Name System’ course, participants will obtain a theoretical and practical knowledge of DNS zone management operations, with a focus on security, including:

  • a clear overview of the DNS namespace;
  • a comprehensive knowledge of the DNS protocol;
  • a complete understanding of the DNS resolution process;
  • an introduction to domain name management;
  • a focus on DNS threats and privacy/security concerns in the DNS;
  • a hands-on implementation of a DNS zone management infrastructure.
