Let’s talk trends. As of this very moment, 93% of all US & EMEA organizations are using at least one cloud-based technology. Public cloud revenue is expected to grow from $146 billion (2017) to $236 billion by 2020 as companies increasingly transition from a cloud-first to a cloud-only strategy . In fact, the new industry standard is the use of multiple clouds and most enterprises are already opting for a hybrid cloud environment . Moreover, between 67% and 75% of companies are estimated to be using a hybrid cloud structure. These numbers are growing rapidly as businesses look to leverage the benefits of both, the more stable private cloud as well as the more flexible and scalable public cloud. However, as the majority of global companies move to the cloud, the question of security still remains.

Cloud advantages

Whether it’s AWS, Azure or Google Cloud, the cost of having your services in the cloud is reducing, and the ability to save IT expenditure is probably the main driver behind the global trend to shift more and more services and data into the cloud. IT budgets receive another boost through cloud technology usage as its costs typically fall under operating expenditure (OPEX) instead of capital expenditure which allows for more financial flexibility.  As a result, cloud technology allows companies with less resources to get access to the best technology previously only available to big enterprises.

Understanding Australian Metadata Retention

Australia has passed laws that force Communication Service Providers (including ISPs) to perform metadata collection and retention for use for security purposes by a few government agencies.

Complying with such metadata retention laws is not an easy task from a technical standpoint. We have compiled a whitepaper reviewing the requirements imposed on service providers and how they can comply without too many headaches.

Why do cybercriminals love DDoS attacks so much?

Just last month, a major cyberattack brought down the likes of Twitter, Soundcloud, Spotify and Airbnb for a few hours. Interestingly, rather than directly attacking the infrastructure of these companies, the assault targeted the domain name system (DNS) host Dyn, which is relied upon by the sites above. This is how a single attack could bring down so many sites at once.

(As you may already know, DNS a bit like the yellow pages of the Internet - but rather than mapping people's names to phone numbers, it maps domain names to IP addresses, which computers require to communicate. Hence, if the DNS provider of a site is down, it cannot be accessed by its users.)

One might imagine that pulling off an attack of this magnitude would require extreme sophistication. In practice, the disruption was caused by a rather rudimentary Distributed Denial of Service (DDoS) attack that overwhelmed the DNS servers of the aforementioned sites.
