Oracle’s infrastructure business focuses on bare metal to go after AWS

Larry Ellison made a splash this week when he said that Oracle would give Amazon a run for its money in the cloud. Then, the company outlined the pillar of the tech titan's infrastructure offering: beefy, bare-metal servers running in the cloud. That's right: Oracle is going after a market that's full of virtualized workloads with servers that clock in with a whopping 36 physical CPU cores, according to Vice President of Engineering Don Johnson. Rather than starting from the low end of the infrastructure market and working its way up, Oracle is starting at the top and working its way down. To read this article in full or to leave a comment, please click here

IDG Contributor Network: Data breaches: This time it’s more personal

Summer 2016 was not a good time for data breaches.First, news broke that the Democratic National Committee was hacked, leading to the resignation of DNC Chair Debbie Wasserman Schultz and driving a wedge between Democratic Party members.Later, the World Anti-Doping Agency (WADA) announced that Russian hackers had illegally accessed its Anti-Doping Administration and Management System (ADAMS) database, leaking confidential medical information for U.S. athletes, including Simone Biles and Serena Williams.To read this article in full or to leave a comment, please click here

Can I2RS Keep Up? (I2RS Performance)

What about I2RS performance?

The first post in this series provides a basic overview of I2RS; there I used a simple diagram to illustrate how I2RS interacts with the RIB—

rib-fib-remote-proxy

One question that comes to mind when looking at a data flow like this (or rather should come to mind!) is what kind of performance this setup will provide. Before diving into the answer to this question, though, perhaps it’s important to ask a different question—what kind of performance do you really need? There are (at least) two distinct performance profiles in routing—the time it takes to initially start up a routing peer, and the time it takes to converge on a single topology and/or route change. In reality, this second profile can be further broken down into multiple profiles (with or without an equal cost path, with or without a loop free alternate, etc.), but for our purposes I’ll just deal with the two broad categories here.

If your first instinct is to say that initial convergence time doesn’t matter, go back and review the recent Delta Airlines outage carefully. If you are still not convinced initial convergence time matters, go back and reread what you can Continue reading

TLS 1.3 gets early adoption boost through CloudFlare

Website security and performance vendor CloudFlare has made the newest version of the TLS secure communications protocol available to all of its customers.The TLS (Transport Layer Security) 1.3 specification is yet to be finalized by the Internet Engineering Task Force (IETF), the body that develops internet standards. However, the protocol is already supported in beta versions of Google Chrome and Mozilla Firefox, and it's being hailed as an important step forward in securing internet communications.TLS 1.3 removes some cryptographic algorithms present in TLS 1.2 that are known to be vulnerable. This makes it easier for server administrators to deploy secure-by-default HTTPS configurations. HTTPS (HTTP Secure) is a mix between HTTP and TLS.To read this article in full or to leave a comment, please click here

Stanford researchers invent tech workaround to net neutrality fights

Engineers at Stanford University have invented a new technology that would give broadband customers more control over their pipes and, they say, possibly put an end to a stale net neutrality debate in the U.S.The new technology, called Network Cookies, would allow broadband customers to decide which parts of their network traffic get priority delivery and which parts are less time sensitive. A broadband customer could then decide video from Netflix should get preferential treatment over email messages, for example.The technology could put an end to the current net neutrality debate focused on whether broadband providers are allowed to prioritize some network traffic and block or degrade other traffic, said the researchers, Professors Nick McKeown and Sachin Katti and electrical engineering grad student Yiannis Yiakoumis.To read this article in full or to leave a comment, please click here

Data hoarding site represents the dark side of data breach monitoring

A site that's been warning the public about data breaches might actually be doing more harm than good.Enter LeakedSource, a giant repository online that can potentially make hacking easier. Your email address and the associated Internet accounts -- including the passwords -- is probably in it.In fact, the giant repository is made up of stolen databases taken from LinkedIn, Myspace, Dropbox, and thousands of other sites. It bills itself as a data breach monitoring site and for months now, it's been collecting details on hacks, both old and new, and alerting the media about them.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Zuznow (who?) offers a Siri-like tool for developers

Zuznow is a little-known vendor that offers a mobile development platform. Essentially Zuznow is focused on enabling businesses, even those businesses without technical development resource on staff, to create mobile applications. It’s a busy space, and it's getting busier—large vendors (Salesforce, BMC), smaller vendors (Caspio, Mendix) and standalone mobile application development platforms (Xamarin) are all trying to solve this problem.+ Also on Network World: Will companies trust their communications to AI chatbots? + Zuznow wants to steal a march on the opposition with the introduction of its intelligent voice assistant. The tool can be thought of as a plug-and-play Siri. Indeed Zuznow has even called the offering Susie, as an homage of Apple’s Siri voice assistant. Zuznow promises that it is delivering the world's first intelligent assistant plugin that brings voice-control and chatbots to any enterprise mobile app within hours. To read this article in full or to leave a comment, please click here

BackConnect’s Suspicious BGP Hijacks

Earlier this month, security blogger Brian Krebs broke a story about an Israeli DDoS-for-hire service, vDOS, which had been hacked, revealing “tens of thousands of paying customers and their (DDoS) targets.”  Afterwards, Krebs noticed that vDOS itself was also a victim of a recent BGP hijack from a company called BackConnect, which claims to be the “world’s first and leading open source based DDoS and network security provider.”

Bryant Townsend, CEO of BackConnect, confirmed to Krebs that they had indeed conducted a BGP hijack on vDOS, but claimed that it was for “defensive purposes.”  In an email to the NANOG list, Townsend explained that in doing so they “were able to collect intelligence on the actors behind the botnet as well as identify the attack servers used by the booter service,” implying this was a one-time event.  Krebs then contacted Dyn for some assistance in researching what appeared to be a series of BGP hijacks conducted by BackConnect over the past year.  What emerges from this analysis is that the hijack against vDOS probably wasn’t the first time BackConnect used BGP hijacks in the course of its business.  And via the use of Continue reading

BrandPost: Driven to Connect

Businesses large and small are under the gun to satisfy network access for varied constituencies: not only centralized and remote workers, but outsiders ranging from consumers to partners. Typically, that means supporting multiple access technologies such as a secure virtual private network (VPN) and any number of Wi-Fi guest access devices.Businesses typically have spent years trying to catch up with the access needs of their workers. Larger firms may use a variety of networking technologies from high-performing carrier-based Multiprotocol Label Switching (MPLS) virtual private networks (VPNs), campus or metro Ethernet local area networks (LANs), and public internet VPNs. Smaller organizations are more likely inclined to the public internet options.To read this article in full or to leave a comment, please click here
