The IaC (Infrastructure as Code) approach consists not only of the code that is stored in the repository, but also of the people and processes that surround this code. Is it possible to reuse approaches from software development to infrastructure management and description? It would be a good idea to keep this idea in mind while you read the article. English version This is a transcript of my speech at DevopsConf […]

A group of researchers from the Vrije Universiteit Amsterdam and ETH Zurich have developed a network attack technique called NetCAT (Network Cache ATtack), which allows, using side-channel data analysis methods, to remotely determine the keys pressed by a user while working in an SSH session. The problem only appears on servers that use RDMA (Remote direct memory access) and DDIO technologies […]
