Cisco VIRL Exclude From Launch

<hr> One of the few pet-peeves with Cisco’s VIRL has been waiting for a bunch of things to start, when I just needed a couple from that simulation. Not sure if this is a new update though it’s...

Lyft turns to Verizon for an edge against Uber

Lyft is looking to better compete against larger rival Uber through a partnership with Verizon Wireless.Lyft’s ride-hailing app will now come preloaded on select Verizon Android smartphones, under a national partnership with the carrier that Lyft is announcing Thursday. The change will go into effect immediately for the newest Android smartphones, Lyft said. It didn’t specify which handsets are included. The partnership does not change the way Lyft’s app works.The deal, the first of its kind between the companies, will get Lyft’s app in front of more potential users. Lyft’s service, which lets people request rides through their smartphones, is currently available in 65 cities across the U.S. Uber is active in more than 300 cities and nearly 60 countries.To read this article in full or to leave a comment, please click here

Overwhelmed – CCDE

I am preparing for the CCDE written exam, which I have coming up at CLUS.

There are so much material to go through, both to read as well as watch CL presentations, it can be a bit overwhelming at times.

So if you are thinking about going down this path, learn how to speed-read :)

Just under a month until we leave for the US. We are looking very much forward to the break!

Just a quick thought for the day!

Cloud disasters can and will happen. Are you prepared?

It's going to happen, and happen to you and your organization. No, I'm not a salesguy, otherwise bereft of booth babes at RSA. I'm a systems engineer going back to the days of SNA, DSLAMs, CSU/DSUs, ARCNet over NetWare, and other ancient interconnect. Stuff happens.So, whatchya gonna do? What is your plan?Did you notice how none of this cloud stuff talks to none of this cloud stuff among competing vendors? Even the mighty Open Data Center Alliance can't help you if you don't have a plan, and haven't tried to do a failover successfully.This year, thankfully, we dodged a number of hurricanes and tornadoes. The snows were gruesome, but it was rare to see data centers go down because of it. The cloud usually kept on ticking.To read this article in full or to leave a comment, please click here

Appeals court rules against NSA phone records collection

The U.S. National Security Agency’s program to collect domestic telephone records in bulk was not authorized by Congress in the Patriot Act, an appeals court has ruled.The NSA’s phone records program violates U.S. law because it “exceeds the scope of what Congress has authorized,” a three-judge panel for the U.S. Court of Appeals for the Second Circuit has ruled.The appeals court vacated a December 2013 ruling by a district court judge who granted the government a motion to dismiss the case, but upheld the district court decision to deny plaintiffs, including the American Civil Liberties Union, a preliminary injunction to halt the so-called phone metadata collection program.To read this article in full or to leave a comment, please click here

WordPress fixes actively exploited flaw

A new WordPress version released Thursday fixes two critical cross-site scripting (XSS) vulnerabilities that could allow attackers to compromise websites.One of the flaws is located in the Genericons icon font package that is used by several popular themes and plug-ins, including the default TwentyFifteen WordPress theme.Researchers from Web security firm Sucuri warned Wednesday that they’ve already seen attacks targeting this XSS vulnerability.To exploit it, attackers need to trick users to click on specifically crafted links, but once they do that, they can leverage the flaw to steal authentication cookies. If the victim is a website’s administrator, they could gain full control over that website.To read this article in full or to leave a comment, please click here

Five reasons threat intelligence fails today, and how to overcome them

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.

As cyber security threats have become increasingly sophisticated and pervasive, it’s become impossible to identify and defend against every probable attack with traditional security budgets. That’s where threat intelligence comes in. Effective use of threat intelligence is a way for businesses to pool their resources and overcome internal technical or resource limitations. Theoretically, it allows companies to “crowd source” security and stay one step ahead of malicious entities.

Alibaba names new CEO as revenue jumps

Though Alibaba Group is succeeding in generating more revenue from mobile, it is nevertheless shuffling executives, elevating its chief operating officer Daniel Zhang to CEO in the face of a stock-based compensation program that has depressed profit.Zhang will take over on May 10, and current CEO Jonathan Lu will step down, remaining on Alibaba’s board of directors as vice chairman.The company made the announcement on Thursday, when it reported its first quarter earnings. Alibaba’s profit fell 49 percent year over year to about 2.9 billion yuan (US$476 million). Profit has been weighed down by continued stock awards given to employees since its IPO last year. Without the share-based compensation, Alibaba said its profit would have risen 14 percent.To read this article in full or to leave a comment, please click here

IT/IT: A GUI and a Wizard

One of the brilliant things about conferences like Interop is the hallways (and if you’re not going to Interop, this is why you should be!). It’s not that I don’t enjoy the sessions, but — like the IETF — I often get much more out of the conversations with folks who know networking, and yet have a completely different view of the problems we face in the networking industry, and hence completely different ideas about the way forward in resolving those problems. One of my major problems in life is I often can’t think of a solid answer when I’m sitting there in the conversation itself (one of the reasons I always converted TAC cases to email, rather than sitting on the phone with a customer).

One such conversation (with @cigoodwi) brought out a phrase I thought I’d never hear in the networking world — “a GUI and a wizard.” The context was this: what most x% (your beliefs about the percentage may vary) companies need is a network they can run with a GUI and a wizard. It’s a startling statement, of course, but — in reality — true in many respects. Given this is our Continue reading

UK gang arrested for exporting $10 million of fake Cisco gear to US

Three men accused of selling and exporting over $10 million worth of fake Cisco networking equipment into the U.S. have been arrested by U.K. police.The men are believed to have imported and exported counterfeit Cisco equipment through a company website and telesales. The arrests, made last week by the U.K. Police Intellectual Property Crime Unit (PIPCU), were announced Thursday.“Last week’s action saw PIPCU dismantle a criminal gang suspected of cheating the computer industry out of millions of pounds,” said PIPCU Detective Inspector Mick Dodge, in a statement. Using counterfeit products could also seriously harm businesses that use them, since company network integrity could be compromised and significant network outages could occur, Dodge said.To read this article in full or to leave a comment, please click here

Superfish injects ads in one in 25 Google page views

Over five percent of browser visits to Google owned websites, including Google Search, are altered by computer programs that inject ads into pages. One called Superfish is responsible for a majority of those ad injections.The findings are the result of a study by Google and researchers from the University of California at Berkeley and Santa Barbara, who analyzed over 102 million page views to Google sites between June and September last year.Google added code to its websites that detected and reported back when ads were injected into pages by programs or browser extensions. This revealed that locally installed ad injectors interfered with 5,339,913 page views (5.2 percent of the total), impacting tens of millions of users around the world—or 5.5 percent of unique daily Internet Protocol addresses that accessed Google’s sites.To read this article in full or to leave a comment, please click here
