After a first conclusive experience, Restena is engaged in the winter catalogue 2022/2023 of the Digital Learning Hub (DLH), the continuing professional training structure of the Ministry of National Education, Children and Youth (MENJE). As for the summer course, Restena is involved in the 'Cyber Security' training pillar, this time with a doubled offer. With two new training courses and an additional speaker, representing a total of four training courses and 36 hours of training, Restena is stepping up its commitment to the DLH.

From 24 November to 16 December 2022, three engineers from the Restena Foundation will discuss four essential themes in terms of IT security.

• IPv6 - The successor IP address space to IPv4, IPv6 allows access to the Internet.

➔ Restena allocates IPv6 addresses to the research and education community in Luxembourg.

• Multi-factor authentication (MFA) - MFA allows a secured connection by providing two or more distinct proofs of identity.

➔ Restena has implemented strong, phishing-resistant MFA for its own staff resources, and is working with the international eduroam community to move eduroam accounts towards MFA.

• The Domain Name System (DNS) - DNS is one of the fundamental elements of the Internet that provides a distributed naming system and its complexity has to be considered for the domain name's optimum protection.

➔ Restena manages the authoritative servers for the .lu top-level domain, in the context of its .lu registry activity.

• The DNSSEC (Domain Name System Security Extensions) protocol - DNSSEC is essential to guarantee optimal security for all .lu domain names

➔ A set of "authoritative" servers offered by Restena to the research and education community in Luxembourg and to the users of its online .lu domain name platform is DNSSEC-signed.

Restena's training courses, like all the others in the winter catalogue, lead to the issue of a certificate of participation by the Ministry of National Education, Children and Youth.
