Many hospitals transmit your health records unencrypted

About 32% of hospitals and 52% of non-acute providers -- such as outpatient clinics, rehabilitation facilities and physicians' offices -- are not encrypting data in transit, according to a new survey.Additionally, only 61% of acute providers and 48% of non-acute providers are encrypting data at rest.This "leaves the door wide open to potential tampering and corruption of the data, in addition to a large potential for a breach," the report stated. "If a computer, laptop, thumb drive, or backup were to be stolen, any person would be able to access such information." HIMSS The survey, conducted by the Healthcare Information and Management Systems Society (HIMSS), a Chicago-based trade group for the health information technology sector, also revealed that many of the facilities' networks don't even have firewalls.To read this article in full or to leave a comment, please click here

Linux at 25: Containers and unikernels prove less is more

Containerization, unikernels, and other experiments with form are reshaping Linux from the inside out, opening up unheralded avenues for how the open source operating system that could (and did!) can do it all over again.To read this article in full or to leave a comment, please click here

Imperva: Application layer DDoS attacks are on the rise.

Application layer DDoS attacks are becoming more common, perhaps because they cost less for malicious actors to execute and can more effectively evade defenses than network layer attacks, Imperva says.One such attack generated 8.7Gbps at its peak, “unheard of in relation to application layer assaults,” in an effort to thread its way through the DDoS mitigations that had been set up to defend against such attacks, according to Imperva’s “DDoS Threat Landscape Report 2015-2016” released today.Application layer attacks can be measured in responses per second required from the application targeted, and they generally require less volume than network layer attacks to succeed, the report says. That means they require fewer botnet resources, if botnets are the platform from which the attack is launched.To read this article in full or to leave a comment, please click here
