Spectre and Meltdown: a recap

The first week of the new year was characterized by the appearance of two major flaws in processors, the so-called Meltdown and Spectre announced by Google ProjectZero in this post, which afflict most of computers and devices in use today. The impact has been outstanding in terms of media coverage, and the topic has been the subject of discussion not just among IT professionals.

Meltdown and Spectre briefly

Meltdown and Spectre are two distinct vulnerabilities that affect computer processors: not just servers, laptops and desktops but also micro-computers, specialized computers and IoT devices. They were discovered by four different research teams who reported them to CPU manufacturers, several months prior the publication of the news; but these vulnerabilities are not new, in fact they have existed for decades. No computer with a processor produced in the last 20 years is to be considered immune and safe; a dedicated tool for Linux and BSD is available and provides information on the system status, and a similar tool for Windows exists too.
We are not aware of known attacks: antivirus can detect the code responsible for an attack, but not the vulnerability itself.

HyTrust published its VMworld 2017 Cloud Adoption Survey
HyTrust, an IT company in the security sector, published a report on the enterprise cloud world made during last VMworld 2017.
323 companies were surveyed, and these are the results. 21% of them are concerned about GDPR and have a plan in place and 52% are not concerned about GDPR or are unaware of its relevance for their business and 27% are concerned about GDPR, yet have no plan in place.
Among the other results of the survey, although the hybrid cloud infrastructures are more and more used, 22% don’t use a public cloud, 44% don’t have an hybrid cloud and 28% entrust a single hybrid cloud vendor. The percentage of those who don’t use any form of encryption in a public cloud thankfully lowers from 28% of last year to 10% of this year. The biggest fears in terms of security are about uncontrolled or unmonitored access by admins (32%) and a malicious or accidental exposure of workload data (30%).
Containers are an appealing topic but it’s seldom used in production: just 12% of participants use it a production environment.
