Reading Time: 3 minutesRunecast announces the new release version 1.7 of its proactive issue detection software, Runecast Analyzer. After the Meltdown and Spectre detection added in the previous releases, this latest version brings other interesting news. Runecast Analyzer is powered by the largest database of automated VMware KB articles which feed its internal archive of known issues. The interesting aspect of this tool is that it’s very easy and fast to be deployed and that it can work fully in offline mode!

Reading Time: 6 minutesThe mitigations for Meltdown and Spectre issues have involved a combination of different type of fixes: some software based, such as Microsoft and Linux versions of the “kernel page table isolation” protection, but also fome hardware based, like the Intel’s microcode updates (part that is still missing in most cases). Both type of patches can cause performance overheads and have some kind of impact on your environment. But how can you estimate it (before apply the patches) and how can you measure it (when the patches have been applied)?
Reading Time: 2 minutesWhen you add a Veeam proxy to the Veeam Backup infrastructure, in some cases you can have an error message like this: “Failed to create persistent connection to ADMIN$” And the proxy is not added to the infrastructure. There can be different reason, but the most common case occour when you have proxyes that are “workgroup only” and when you are using dedicated local accounts, and not the “Administrator” one. And you have Windows Server 2012 or later.

Reading Time: 8 minutesIn June 2017, a team constituted of independent researchers, university research labs, and some of Google’s Project Zero members and cyberus technology discovered two security vulnerabilities enabled by the widespread use of speculative execution in most of the CPU. The problem was also independently discovered by other researchers, at about the same time. These vulnerabilities, called Meltdown and Spectre, were made public in January 2018. Meltdown and Spectre are critical vulnerabilities existing in several modern CPU: these hardware bugs allow programs to steal data which is currently processed on the computer. Meltdown and Spectre can affect personal […]
Reading Time: 5 minutesLinux Kernel 4.15 è stato rilasciato il 28 gennaio 2018, dopo un lungo ciclo di sviluppo, tanto da arrivare alla RC9, cosa che non succedeva dal 2011. Questa versione è la prima che contiene specifiche ottimizzazioni e soluzioni specifiche per Meltdown e Spectre issues (benché anche alcuni kernel precedenti avessero alcune protezioni). Notare che in realtà i problemi sono tre problemi distinti: Meltdown è uno, ma poi ci sono due varianti di Spectre (note come v1 e v2). Il Kernel 4.15 al momento manca ancora mancano ancora dei fix per ARM e per la variante 1 […]
