En cumulant ces unités d’enseignement avec deux autres activités d’apprentissage, les candidats pourront valider à leur rythme le certificat de compétence « Analyste en cybersécurité » lui-même intégré dans le parcours de la licence en informatique du Cnam.
EDF propose des coques de couleur pour personnaliser votre compteur Linky
A l’instar de ce qui existe pour les smartphones, EDF va prochainement proposer des coques de couleur pour personnaliser et égayer ses nouveaux compteurs communicants Linky.

I recently update my Metasploit Pentest Plugin . I added 2 new commands to the plugin and fixed issues when printing information as a table. The update are small ones.
Thank the IEEE's business model. The IEEE is the standards body that developed WPA2, and they fund their operations by charging hundreds of dollars to review the WPA2 standard, and hundreds more for each of the standards it builds upon, so that would-be auditors of the protocol have to shell out thousands just to start looking.
Create web form doesn’t have to take hours or even days. You can generate online forms directly from your database. PHP Database Form even automatically builds the data entry rules engine needed to make collecting your data easy, fast and fun.

This is Part 1 of the Comprehensive Guide to Terraform series. In the intro to the series, we discussed why every company should be using infrastructure-as-code (IAC). In this post, we’re going to discuss why we picked Terraform as our IAC tool of choice.
This tutorial shows how you can back up Linux and Windows systems with BackupPC. BackupPC acts as a server and is installed on a Linux system, and from there it can connect to all Linux and Windows systems in your local network to back them up and restore them without interfering with the user's work on that system. On the clients minimal to no configuration is needed. BackupPC supports full and incremental backups, and it comes with a neat web frontend for the administrator and normal user so that backups and recoveries can be managed through a web browser. It should be noted, however, that BackupPC does file-based backups, not bit-wise backups like Ghost4Linux, for example, so it is not made for disk/partition imaging.

So let’s try a not-so-easy exercise: write a script to optimize a directory of images. Yup, I know there are a lot of web services offering this kind of feature

Comme l’IPv6 est prioritaire par rapport à l’IPv4, j’ai décidé de basculer mes DNS en IPv6 ! Sur Windows, j’utilise depuis plusieurs années DNScrypt couplé à Unbound. Pour rappel, DNScrypt permet de chiffrer vos requêtes vers un DNS public de votre choix. Unbound, quant à lui, est un cache DNS qui évite de solliciter en permanence les serveurs publics accessibles par DNScrypt. Sans Unbound, votre résolution DNS risque d’être extrêmement lente !
