Researchers developing autonomous robot surveillance

Oh, now this is peachy. Thanks to a four-year, $1.7 million grant from the U.S. Office of Naval Research, Cornell University researchers plan to develop a robot surveillance system that would involve robots sharing “information as they move around, and if necessary, interpret what they see. This would allow the robots to conduct surveillance as a single entity with many eyes.” This would be done allegedly to “protect you from danger.”According to the robot surveillance project paper "Convolutional-Features Analysis and Control for Mobile Visual Scene Perception,” researchers want to develop a surveillance method that could do more than any surveillance to date, as it would “operate autonomously and robustly under unknown, and possibly disconnected, topologies.”To read this article in full or to leave a comment, please click here

Microsoft’s new software tool helps enterprises evaluate cloud move

IT professionals who want help getting a handle on a potential cloud migration have a new tool from Microsoft. The company is offering a Cloud Migration Assessment service that walks customers through an evaluation of the resources they currently use, in order to determine what a move to the cloud would cost.Microsoft’s cost calculation is driven in part by the Azure Hybrid Use Benefit , which lets customers apply their existing Windows Server licenses with Software Assurance to virtual machines running in Microsoft’s cloud. That means customers only have to pay the base price for the compute resources they use.To read this article in full or to leave a comment, please click here

Worth Reading: Too big not to fail

It’s predictability that matters, not reliability. Stuff can fail… Stuff will fail. With tens of thousands of servers, lots of stuff fails every day! You just need to predict how often. … Baroque is an architectural style with a lot of ornate detail and tremendous variety. In a largescale environment, bespoke becomes baroque. The individual details of the various types of servers become overwhelming. The aggregate system with its large number of server types is full of detail and complexity. —ACM

Changing Internet Standards to Build A Secure Internet

We’ve been working with registrars and registries in the IETF on making DNSSEC easier for domain owners, and over the next two weeks we’ll be starting out by enabling DNSSEC automatically for .dk domains.

DNSSEC: A Primer

Before we get into the details of how we've improved the DNSSEC experience, we should explain why DNSSEC is important and the function it plays in keeping the web safe.

DNSSEC’s role is to verify the integrity of DNS answers. When DNS was written in the early 1980’s, it was only a few researchers and academics on the internet. They all knew and trusted each other, and couldn’t imagine a world in which someone malicious would try to operate online. As a result, DNS relies on trust to operate. When a client asks for the address of a hostname like www.cloudflare.com, without DNSSEC it will trust basically any server that returns the response, even if it wasn’t the same server it originally asked. With DNSSEC, every DNS answer is signed so clients can verify answers haven’t been manipulated over transit.

The Trouble With DNSSEC

If DNSSEC is so important, why do so few domains support it? First, for a domain to Continue reading

There’s never been a better time for Cisco Services

About a year ago, Cisco embarked on a new branding campaign, telling its customers there’s “Never Been A Better Time” to become a digital organization and create new experiences for employees and customers. However, the path to becoming digital may not be that obvious, as we are connecting more things to our network, costs are escalating, the skills gap is widening, and IT is becoming more dynamic and distributed. + Also on Network World: Cisco targets digital business transformation with new certifications + Put this all together, and CIOs face a difficult situation. Digital transformation requires businesses to use technology to move fast, but IT complexity is clearly on the rise. Technology leaders are now in a situation that seems to be untenable: Accelerate business transformation while trying to completely revamp the way IT is run within the organization. I’ve heard the analogy that it’s like changing the wings on a plane while it’s flying, but it’s more like changing the entire plane and the people flying it while flying.

Face-off: Cisco vs. Fortinet for enterprise firewalls

Firewalls have been on the front lines of network security for 25 years. Over time they’ve evolved beyond simple packet filtering to take on a wider and deeper variety of tasks to block modern threats. Today, two of the top enterprise firewalls are Cisco’s Adaptive Security Appliance (ASA) and Fortinet’s Fortigate, according to reviews by users in the IT Central Station community.One reviewer, a manager of engineering at a retailer, says Cisco’s ASA is “a solid, stable and consistent firewall platform,” but there’s room for improvement when the enterprise needs to manage multiple firewalls from a central point. “Cisco’s answer is Cisco Security Manager (CSM). Unfortunately, this is a suite of applications that is in much need of an overhaul. It is riddled with bugs and lacks the intuitive experience found in competing vendor offerings.”To read this article in full or to leave a comment, please click here(Insider Story)
