Leaky IoT devices help hackers attack e-commerce sites

Millions of IoT devices are misconfigured so that they can forward messages -- which, combined with default admin settings, allows them to be used to attack e-commerce and other websites, a new report says.The problem is well known and has been around for a more than a decade, said Ryan Barnett, principal security researcher at Akamai Technologies, which produced the report.The problem first came to Akamai's attention when the content delivery network noticed attacks against its customers where the attackers were checking to see whether particular user name and password combinations were valid on the site.To read this article in full or to leave a comment, please click here

Attackers Exploit Weak IoT Security

Record IoT DDoS attacks raise bar for defenders

Now that its source code has been released you can expect more attacks from Mirai, the malware behind the largest DDoS attack on record, which was powered by hijacked IoT devices.Since release of that code last week it has been responsible for smaller attacks that look like newcomers experimenting with the malware in preparation for bigger things, say security researchers at Imperva. “Likely, these are signs of things to come and we expect to deal with Mirai-powered attacks in the near future,” they say in their blog post.That concern is echoed by researchers at F5, who say, “we can definitely expect the IoT DDoSing trend to rise massively in the global threat landscape.”To read this article in full or to leave a comment, please click here

IDG Contributor Network: Are enterprises successfully escaping Mainframe Island?

From time to time, a vendor's PR rep sends me a note about the "problem" that is caused by mainframe systems being at the hub of enterprise computing. In reality, these systems often offer more integrated processing power, larger memory capacity and more efficient database operations than a distributed, x86-based solution.The most recent pitch I received included this sentence: "How the dusty old legacy mainframe holds back cloud initiatives... and how it can be modernized."What are the real costs? Part of the reason mainframes won't die is that often they simply cost less to operate when all of the costs of ownership and workload operations are considered.To read this article in full or to leave a comment, please click here

National Science Foundation doles out $12M for wireless growth

The U.S. National Science Foundation yesterday handed out 11 grants, totaling $12 million, to researchers working on bringing the benefits of the public airwaves to more Americans than ever before.The awards went to researchers at a diverse range of educational institutions, including the U.S. Naval Academy, Virginia Tech, Wisconsin, and Texas A&M, among others. The research itself tended to center on work that makes spectrum sharing easier, freeing up space across the increasingly crowded airwaves.Specifically the NSF said the awards were directed at four major areas, including: Innovative radio hardware and access architectures to enable spectrum sharing. Harmonious co-existence of heterogeneous wireless technologies. Development of automated detection mechanisms and compliance certification methods. Spectrum access for science services. +ALSO ON NETWORK WORLD: With help from Docker, Google's Go jumps in popularity + Wi-Fi vs. LTE could be the start of a mobile rollercoasterTo read this article in full or to leave a comment, please click here

Game on: Alienware’s 20-year affair with gaming helps drive the future of VR

Alienware co-founder Frank Azor has fond memories of the comany's early days. It was a wild time of building kick-ass PCs, gaming, lots of sci-fi shows and generally, having a good time. "It was four guys in a tiny little office, sending in a couple of review machines, magazines saying they were great, and the phone beginning to ring very, very slowly. We would sell about one computer every day, maybe," Azor said. October 15 marks 20 years of Alienware's existence. Now a part of Dell, Alienware has matured into a PC gaming powerhouse. It is also driving big changes for virtual and mixed reality, which Azor believes will drive PC growth in the coming decades.To read this article in full or to leave a comment, please click here

Nurturing tomorrow’s techies STEMs from promoting technology in schools

With the school year underway, I’m reminded about the critical role that education and technology play in our future. Whatever your role—parent, teacher, student, mentor, employer, employee—technology literacy needs to be a priority. For those involved with elementary school students, the best place to start is emphasizing education that promotes science, technology, engineering and math (STEM). + Also on Network World: STEM majors dominate salary-based college ranking +STEM programs offer an excellent opportunity to infuse technology into the learning process early on. Business and education experts agree that STEM education better prepares students and opens the door for greater career options. A STEM-based education is important because some element of science, technology, engineering and/or math is evident in most well-paying jobs. A recent article in Network World stated a majority of the highest-paying college majors are in engineering, led by petroleum engineers with a mid-career median salary of $172,000, according to Payscale. To read this article in full or to leave a comment, please click here

Do I Need Redundant Firewalls?

One of my readers sent me this question:

I often see designs involving several more than 2 DCs spread over different locations. I was actually wondering if that makes sense to bring high availability inside the DC while there's redundancy in place between the DCs. For example, is there a good reason to put a cluster of firewalls in a DC, when it is possible to quickly fail over to another available DC, as a redundant cluster increases costs, licenses and complexity.

Rule#1 of good engineering: Know Your Problem ;) In this particular case:

BGP in MPLS Layer 3 VPN – BGP as a PE-CE Routing Protocol

BGP can be used as a PE-CE routing protocol in MPLS Layer 3 VPN. Also Service Providers run MP-BGP (Multiprotocol BGP) if they have MPLS Layer 3 VPN. In this article, MP-BGP will not be explained since it has been explained here earlier in detail. When BGP is used as a PE-CE routing protocol between […]

ICANN and the future of DNS and internet

How Does Internet Work - We know what is networking

I sorry to put here something that is not really technical but with a blog with the name “howdoesinternetwork.com” it would be strange not to follow the story about the future of DNS governance giving the fact that DNS is a crutial part of internet functionality. You probably know how the internet works giving the fast that you are visiting a blog like this. Regardless of that, it will not hurt to explain in few words the importance of DNS (Domain Name System) for normal internet operation.

Disruptive Technologies on the Post Exascale Horizon

Although the timeline for reaching exascale class computing continues to stretch farther into the future, research teams are keeping an eye on what technologies will shape the machines of the post-exascale timeframe, which is in the 2022-2030 timeframe.

While many of the technologies stated in a comprehensive report about post-exascale supercomputers are already in process, albeit in various stages of development and adoption, there is little consensus about which mode of computing will lead us into an era of unprecedented data and simulation potential. Still, the effort on behalf of the EuroLab-4-HPC program is notable in its divisions between where …
