Microsoft fleshes out seismic change to Windows patching

Microsoft has elaborated on the new patching policy for Windows 7 and Windows 8.1 that takes effect Tuesday.In a post to a company blog accompanied by graphics that resembled a periodic table, Michael Niehaus, a product marketing director for Windows 10, fleshed out the massive change in how Windows 7, the standard in business and the most popular OS on the planet, will be serviced starting with this month's Patch Tuesday.Microsoft announced the new plan two months ago, saying then that as of Oct. 11 it would offer only cumulative security updates for Windows 7 and 8.1, ending the decades-old practice of letting customers choose which patches they apply.To read this article in full or to leave a comment, please click here

7 ways to take back control of your cloud strategy

The age of shadow ITImage by ThinkstockIn 2015, 35 percent of IT spend was managed outside of IT departments, and by 2017, Gartner predicts that CMOs alone will spend more on IT services than CIOs. This includes both insecure and secure cloud apps and services that employees and business units are increasingly adopting without ITs knowledge or oversight – a movement known as Shadow IT. Today, every department from accounting to engineering is stealthily adopting these cloud services, causing serious problems for IT professionals who have to then quickly gain visibility and control over these services. What’s more, this process threatens to render IT irrelevant in critical IT purchasing and planning decisions.To read this article in full or to leave a comment, please click here

Is tape storage dead … again?

Much like the mainframe, tape still has its place. It’s a veteran technology that is heralded for being cheap, reliable and simple, and advancements continue. Even so, by the time you’ve invested in tape robots for automation and verification steps to make sure your backup actually captured your data, all that labor and infrastructure means tape isn’t as cheap as the per-megabyte costs make it look.To read this article in full or to leave a comment, please click here(Insider Story)

How older workers can thrive in IT

Mark Zuckerberg's infamous foot-in-mouth statement on the importance of being young and technical ("young people are just smarter") landed him in a lot of hot water. But regardless of whether you believe that technology's best left to the young generation or you think that it's wasted on the young, to paraphrase George Bernard Shaw, there's no question that it becomes ever more difficult to find a job in tech the older you get.But as Silicon Valley struggles with its exclusionary image, recruiters and hiring managers are including age -- in addition to gender, race, ethnicity, education and work history -- as an underrepresented group that deserves consideration.To read this article in full or to leave a comment, please click here

Yahoo Mail suspends automatic mail forwarding as privacy controversies swirl

In what can only be called awfully suspicious timing, Yahoo has turned off automatic email forwarding—a crucial feature when changing email accounts—for Yahoo Mail users. Anyone who has already enabled the feature is not affected, but others cannot activate it.On its help pages, Yahoo says mail forwarding is currently under development. “While we work to improve it, we’ve temporarily disabled the ability to turn on Mail Forwarding for new forwarding addresses,” the help page says.To read this article in full or to leave a comment, please click here

Say Cheese: a snapshot of the massive DDoS attacks coming from IoT cameras

Over the last few weeks we've seen DDoS attacks hitting our systems that show that attackers have switched to new, large methods of bringing down web applications. They appear to come from the Mirai botnet (and relations) which were responsible for the large attacks against Brian Krebs.

Our automatic DDoS mitigation systems have been handling these attacks, but we thought it would be interesting to publish some of the details of what we are seeing. In this article we'll share data on two attacks, which are perfect examples of the new trends in DDoS.

In the past we've written extensively about volumetric DDoS attacks and how to mitigate them. The Mirai attacks are distinguished by their heavy use of L7 (i.e. HTTP) attacks as opposed to the more familiar SYN floods, ACK floods, and NTP and DNS reflection attacks.

Many DDoS mitigation systems are tuned to handle volumetric L3/4 attacks; in this instance attackers have switched to L7 attacks in an attempt to knock web applications offline.

Seeing the move towards L7 DDoS attacks we put in place a new system that recognizes and blocks these attacks as they happen. The Continue reading

Samsung discontinues Galaxy Note7 after battery debacle

Samsung Electronics has discontinued production of its Galaxy Note7 smartphone, which has been plagued since its introduction in August by battery problems that caused fires and even explosions.The company confirmed Tuesday that it is discontinuing production, a day after it said that it had advised carriers and retail partners worldwide not to sell or exchange the replacement Note7 phones that were intended to solve an issue of overheating batteries in the previous version.U.S. carriers including Verizon, AT&T and T-Mobile announced over the weekend that they would stop the exchange of the smartphone after reports of fires and explosions involving the replacement smartphones, including a report of a Note7 that caught fire on a Southwest Airlines flight. Samsung said last week it was investigating the reports.To read this article in full or to leave a comment, please click here

A breach alone means liability

Rich Santalesa, a programmer turned writer and lawyer, brought an interesting turn of events to my attention last week. We need to pay heed: A litigant can have standing in a U.S. Federal breach case where no personal fraud or identity theft has yet occurred.Usually, a litigant has to have suffered injury—a breech caused them identity theft or other fraudulent activity based upon information released in a security breach. This means if you’re cracked, you can be liable if personally identifiable information is released, exfiltrated, absconded, whatever. It also means that should you believe the axiom that currently most of us are hacked, we’re in for a litigious treat. To read this article in full or to leave a comment, please click here

IDG Contributor Network: Shining a light on LiFi in the enterprise

Even as we increase data rates and network capacity in Wi-Fi with 802.11ac, 11ad and then 11ax, it’s worth keeping an eye on other communication technologies that may become useful in the enterprise. Visible light communication (VLC) is making progress in the background, and while it is barely out of the lab, it may take off in a few years. The startups working with enterprise VLC are adopting the term “LiFi” (although it has—today—no connection with Wi-Fi). Like all new technologies, there are many possibilities—and the number of potential uses is impressive. Applications include vehicle-to-vehicle, underwater communications, streetlamps, aircraft cabins, and industrial uses where Wi-Fi cannot be used due to RF interference.To read this article in full or to leave a comment, please click here

The Two Principles Of Troubleshooting

  1. Never trust someone else’s configuration.
  2. Don’t trust your own configuration.

But in all seriousness. If you’re migrating configuration, this would be a good place to start:

  • Check all your IP addresses are consistent.
  • Check your masks are consistent.
  • Check your interfaces are correct.
  • If you’re working with peers, check your IP addresses for the peers are correct.I mean all 4 octets. Not just the last one, or two, or three. ALL FOUR. If it’s v6, then FML. Bite the bullet and write a script.
  • Is there a naming convention to follow? There’s a temptation when migrating to stick with the old name, but new devices may require a different convention is adhered to. Reasons for this range from the whimsical to the valid.

If you’re coming up with something new, and it involves addressing new interfaces then start with this:

  • First check your IP allocations are correct. By this, I mean check if you have any hierarchy or ordering. For example, do you reserve addresses by site, geographic location or application? If you do, then make sure these are consistent with what you’ve planned.
  • Is your addressing valid? i.e: Are the subnets and host addresses you’ve assigned correct? Continue reading

Supreme Court will hear Samsung, Apple damages dispute on Tuesday

The U.S. Supreme Court is to hear arguments Tuesday in a closely-watched dispute between Samsung Electronics and Apple on the procedure for calculation of damages for the infringement of design patents.In general terms, a design patent protects the way an article looks, while utility patents address the way an article is used and works, according to the U.S. Patent and Trademark Office. Some older Samsung smartphones were found by a jury in 2012 to have infringed three design patents related to the look of the iPhone, including its face and rounded bezel design, and the icon layout on the home screen.To read this article in full or to leave a comment, please click here

Apple shares rise as Samsung’s Galaxy Note 7 woes continue

At the end of the trading day on Monday, shares of Apple were up nearly 1.75% before ultimately closing at $116.05 per share. All told, Apple stock is now trading at levels not seen since December of 2015.Part of the recent upswing in Apple shares can of course be attributed to better than anticipated iPhone 7 demand. Though the iPhone 7 was initially pegged as a lackluster upgrade, consumers on the whole appear to be impressed with the device's new camera and blazing fast hardware. Recall, pre-orders for the iPhone 7 set new records at both Sprint and T-Mobile.Additionally, analyst reports in recent weeks have suggested that many iPhone buyers are opting for the more margin-friendly iPhone 7 Plus, further padding Apple's bottom line in the process.To read this article in full or to leave a comment, please click here
