AT&T extends NetBond service to secure IoT connections

The internet is what made IoT happen, providing a common protocol to take the place of separate, specialized networks. But the public internet itself may not always be the best path between a connected device and the cloud.Enterprises can now connect cellular IoT devices to back-end systems via NetBond, a private network service from AT&T, instead of the Internet. The NetBond service sets up a VPN (virtual private network) from an edge device to the cloud. It can connect to 16 different public clouds, including Amazon Web Services and Microsoft Azure, or a private or hybrid cloud.To read this article in full or to leave a comment, please click here

RSA 2017: The Internet of Things security threat

RSA Conference 2017 will take on the threat posed by the internet of things, something that was demonstrated last fall by the DDoS attacks that took down Dyn data centers and many of the high-profile Web sites it supports.Those attacks, generating peak traffic of 1TByte or more, raise the question of how best to secure these devices, and sessions at the Feb.13-17 conference in San Francisco try to answer it.+More on Network World: Cisco: Faulty clock part could cause failure in some Nexus switches, ISR routers, ASA security appliances+To read this article in full or to leave a comment, please click here

iPhone 8 Rumor Rollup: Paying a price for cool & an Apple-of-your-eye camera design

While we've all been busy watching for the newest iPhone 8 leaks, Apple has apparently been selling iPhone 7 and 7 Plus smartphones like crazy. With all the buzz about Apple's record-breaking iPhone sales in Q1 of 2017, iPhone 8 rumors had to take a back seat.But enough about the iPhone 7...Even More Expensive iPhones At $650 or $770 for an iPhone 7 or 7 Plus, respectively, Apple's smartphones certainly aren't cheap. But Apple might be asking patrons to pay even a bit more for the iPhone 8, if the latest reports can be believed.To read this article in full or to leave a comment, please click here

AWS quarterly revenue continues to rise, but growth slows

The rocketship of cloud growth continued at the end of 2016 for Amazon Web Services. The public cloud provider announced Thursday that it brought in a little more than $3.5 billion during the fourth quarter of last year, up 47 percent from the same period in 2015. Quarterly operating income rose 60 percent to $926 million, compared to $580 million during the prior year quarter. That's nothing to sneeze at, but AWS's revenue growth was the lowest it has been in the past two years. There are a number of potential explanations for that, including seasonal changes in cloud migrations, and increasing difficulties on Amazon didn't provide an explanation for that, but it likely has to do with AWS's growing revenue base overall.To read this article in full or to leave a comment, please click here

IRS warns on ever-changing “dangerous W-2 phishing scam”

Just as tax season gets underway in earnest, the Internal Revenue Service put out a warning about what it called dangerous, evolving W-2 scams that are targeting corporations, school districts and other public and private concerns.“This is one of the most dangerous email phishing scams we’ve seen in a long time. It can result in the large-scale theft of sensitive data that criminals can use to commit various crimes, including filing fraudulent tax returns. We need everyone’s help to turn the tide against this scheme,’’ said IRS Commissioner John Koskinen in a statement. “Taxpayers should avoid opening surprise emails or clicking on web links claiming to be from the IRS. Don’t be fooled by unexpected emails about big refunds, tax bills or requesting personal information. That’s not how the IRS communicates with taxpayers.”To read this article in full or to leave a comment, please click here

Obama-led sanction accidentally hampered U.S. tech firms in Russia

Sanctions imposed by former President Obama on Russia for hacking during the U.S. election had an unintended side effect: they essentially barred U.S. tech firms from selling new IT products in the country.Part of last month's sanction order was designed to block U.S. companies from doing business with Russia’s Federal Security Service, also known as the FSB, because of its suspected role in influencing last year’s election.But the FSB isn’t just an intelligence agency. It’s also a crucial regulator in Russia that clears new IT products, including smartphones and tablets, for sale in the country.To read this article in full or to leave a comment, please click here

100G & 25G Plugfests: What we learned

Howdy.

Happy Chinese New Year Y’all!!!

I wanted to take the time and talk about the 25/100G trend we find ourselves in. With more and more platforms being added (Cumulus Linux supports 9 of these platforms with the 3.2 release and we have plans to add more over the next few months), and more customers making the switch to 25/100G as a way to future-proof their networks given the economics of 25/100G open networking switches being on par with their 10/40G counterparts, it’s clear that the 25/100G trend is picking up speed. It was a long journey to get to this point, and we learned a lot on the way. I’d like to take this opportunity to take a look back, analyze the situation and highlight a few things we learned as an industry.

Setting the stage: A short history of the 25G and 100G rush

I don’t know if y’all remember the 100G race between vendors in 2015 to deliver the first 100G switch based on the new 28 GHz standard; everyone had to be first in the market. We even had a handful of 100G switch submissions to OCP by mid 2015. Plus, for the first time Continue reading

Microsoft asks Trump administration for travel ban exceptions

Microsoft today asked the U.S. government to create a mechanism for granting exemptions to last week's executive order on immigration that would meet "the pressing needs of real people," including scores of company employees and their families.In the letter to the heads of the Department of State and Department of Homeland Security, Brad Smith, Microsoft's chief legal officer, asked for exemptions that would apply to people with non-immigrant work visas, student visas or family members. The exceptions would let them come to and go from the U.S. for business trips and family emergencies, those trips not to exceed two weeks.To read this article in full or to leave a comment, please click here

IDG Contributor Network: SSL or IPsec: Which is best for IoT network security?

Internet of Things (IoT) devices are soon expected to outnumber end-user devices by as much as four to one. These applications can be found everywhere—from manufacturing floors and building management to video surveillance and lighting systems.However, security threats pose serious obstacles to IoT adoption in enterprises or even home environments for sensitive applications such as remote healthcare monitoring. IoT security can be divided into the following three distinct components: Application service End device Transport Although all three are critical for systemwide security, this post will address only transport security.To read this article in full or to leave a comment, please click here
