DDoS attacks: Getting bigger and more dangerous all the time
Distributed Denial of Service (DDoS) attacks are more frequent, bigger and more damaging than ever before a new report by internet security firm Verisign has warned.
According to statistic published in the VeriSign Distributed Denial of Service Trends Report, DDoS activity is the highest it's ever been, with the final quarter of 2015 seeing an 85 percent rise in instances - almost double the number of attacks - when compared with the same same period in 2014. The figures for Q4 2015 also represent a 15 percent rise on the previous quarter.
The report also suggests that cyber attackers are getting much more persistent as targets are now being hit by repeated attacks, with some reportedly being the target of DDoS attacks up to 16 times in just three months.

New Name, New Home for the Let's Encrypt Client
Over the next few months the Let’s Encrypt client will transition to a new name (soon to be announced), and a new home at the Electronic Frontier Foundation (EFF).
The goal of Let’s Encrypt is to make turning on HTTPS as easy as possible. To accomplish that, it’s not enough to fully automate certificate issuance on the certificate authority (CA) side - we have to fully automate on the client side as well. The Let’s Encrypt client is now being used by hundreds of thousands of websites and we expect it to continue to be a popular choice for sites that are run from a single server or VPS.
