Don’t Panic! Easy Ways to Prepare for and Survive Website Downtime

It happens to the best of us—websites can experience slow response times or an outage for a number of reasons that are out of your control. Criminals try to penetrate your security perimeter to steal your users’ private data and credit card information. Hacktivists with an opposing view attempt to take your website offline simply because they disagree. Or, a bored teenager on the other side of the world decides to take your website down with a DDoS attack simply because he can.

ELB and Beyond: Introduction to Load Balancing Across Clouds

In a 24/7 world of websites and applications, downtime is simply not an option; uninterrupted availability has become absolutely imperative. Amazon’s Elastic Compute Cloud (EC2) service, along with its Elastic Load Balancing (ELB) offering, addresses this need by offering Amazon Web Services (AWS) users on-demand scalability and availability—as need dictates, additional servers are added to a virtual “data center” and entered into a load balancer’s destination list. This makes Amazon EC2/ELB a great solution for organizations having their entire environments residing within AWS.

Most enterprise-scale organizations, however, do not situate their entire network infrastructures within AWS, Rackspace—or any single cloud environment, for that matter. So, while Amazon ELB does a rather good job of load balancing within its native environment, it doesn’t work outside AWS. This can be a severe limitation in many common-use cases. This post addresses use-cases where ELB is not sufficient and explores load balancing solutions for such scenarios...

DD4BC's Latest DDoS Extortion Campaign Targets The Payment Industry

Over the past month, a number of Imperva Incapsula customers have received email threats from DD4BC—a DDoS group that, despite its boyband-sounding name, was actually responsible for several high-profile DDoS extortion attacks against bitcoin companies last year.

DD4BC's previous attacks targeted bitcoin exchanges and gaming sites, presumably due to the assumption that these types of businesses would refrain from reporting attacks to law enforcement authorities. Based on the recent threats we've seen, it would appear that DD4BC has also started targeting the payment industry...
