Introduction To DNSSEC : DNS Security Extensions

DNSSEC (short for DNS Security Extensions) adds security to the Domain Name System (DNS). In fact, DNSSEC was designed to protect the Internet from certain attacks, such as DNS cache poisoning. DNSSEC is a specification of an extension to the DNS through the definition of additional DNS Resource Records that can be used by DNS clients to validate the authenticity of a DNS response, the data integrity of the DNS response, and where the response indicates no such domain or resource type exists, this negative information can also be authenticated.

Virtual Infrastructure Et Enregistrement De Serveur ESX

Le Client d’infrastructure Virtuelle (ou Virtual Infrastructure Client) permet la gestion centralisée des serveurs ESX, en plus des possibilités de VMotion, et d’autres fonctionnalités.

From Backup Restore Strategy To a Physical To Virtual Technic

Being in holidays, I was called in an emergency for an Ldap database restore because an application was no more running. The fact is, even if we had an image of disks of the physical server hosting the application, we didn’t have backups for files each on by itself available at this time.
