Troubleshoot#1: Correlation vs Causation

Network problems can be as simple as follows: Ping neighbor. 100% packet loss. Check network interface, it’s down. Change SFP and you are done, problem solved But they can also be complex; really complex ..

Apple vs. the FBI: The legal arguments in a nutshell

Apple has raised some interesting, and potentially winning, legal arguments in its motion to overturn a judge’s order requiring the company to help the FBI unlock the iPhone of a mass shooter.The FBI's request for Apple to write new software to defeat password protections on the phone violates the company’s free speech and due process rights, Apple argued Thursday in its motion to vacate Magistrate Judge Sheri Pym’s Feb.16 order.To read this article in full or to leave a comment, please click here

Cloud security is good, but here’s how to make it better

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.

More than a third of businesses in the United States currently use the cloud, but by 2020 that number is expected to more than double to a whopping 80%. But even though the cloud is secure, it doesn’t guarantee immunity from data breaches. Now that the cloud is rapidly becoming a mainstream part of IT, businesses must think more critically about how to bolster their security beyond cloud providers’ default security infrastructure—which often proves to be inadequate for the changing face of business.

Oscar ad finds Carrie Fisher, IBM Watson and robots dealing with humans

Apparently IBM’s Watson isn’t all that popular amongst the robot community – at least that’s how it looks in a new IBM commercial "Coping with Humans": A Support Group for Bots.”In the commercial Carrie Fisher (or Princess Leia of Star Wars fame) tries to guide a raft of disgruntled robots in a therapy session that apparently has had problems in the past – saying “maybe this week we might try and listen more – and throw things less.”It’s pretty funny, take a look. +More on Network World: NASA touts real technologies highlighted in 'The Martian' flick+ To read this article in full or to leave a comment, please click here

Fixing the Internet’s routing security is urgent and requires collaboration

The Internet is fragile. Many of its protocols were designed at a time when the goal was rapid network expansion based on trust among operators. Today, the Internet's open nature is what makes it so great for business, education and communication, but the absence of security mechanisms at its core is something that criminals are eager to exploit.In late January, traffic to many IP (Internet Protocol) addresses of the U.S. Marine Corps was temporarily diverted through an ISP in Venezuela. According to Doug Madory, director of Internet analysis at Dyn, such routing leaks occur almost on a daily basis and while many of them are accidents, some are clearly attempts to hijack Internet traffic.To read this article in full or to leave a comment, please click here

PlexxiPulse—Powering Networks On a Global Scale

The Unabomber’s brother has written a book that I can’t wait to read

David Kaczynski has lived the unimaginable: His brother Ted, the Unabomber, did more than merely kill and maim those who were victims of his attacks, he exacted a terrible toll on his own family, as is always the case with those who commit evil acts.Now David Kaczynski has written a book -- Every Last Tie – that aspires to makes some sense of an otherwise senseless situation.

Implenting Idempotency using HPE IMC

Try saying that five times fast.

What if those VLANS already exist?

There’s a concept called idempotency which can be loosely explained as

Make sure it’s like this. If it’s not like this, make it like this. If it’s already like this. Don’t do anything

Essentially, it’s a way to declare the desired configuration state of whatever it is you’re trying to configure. If the configuration state of that server, or switch or router is already in that state, than just leave it alone.

It’s a way to ensure that configuration drift doesn’t happen.

So if there’s some rabbid network administrator with a console cable running around laughing maniacly as they randomly changes things… this will help you keep them in check.

Idempotent VLANs

So we’re going to look at the last example here where we did the following:

grabbed the jinja template for vlans directly from a GIThub repository
grabbed the desired vlans file directly from a GIThub repository
renderd the Jinja template using the values from the vlan file to get our final config
used the pyhpeimc library to push the commands through the executecmd RESTful API

Worth Reading: The myth of in-memory computing

These days when you talk to people in the tech industry, you will get the idea that in-memory computing solves everything. The story is that RAM has become so cheap that you can just stuff all your data in-memory and you won’t have to worry about speed any more. But it is just a myth. Companies that buy into this myth will almost certainly regret that choice in the near future. -via the next platform

Nexusguard deploys game-changing SDN tech to mitigate large-scale DDoS attacks

This column is available in a weekly newsletter called IT Best Practices. Click here to subscribe. It's easier than ever for a malicious actor to launch a DDoS attack against practically any target in the world. Groups like Lizard Squad sell DDoS-as-a-Service for only a few dollars per hour. Some attackers won’t end their attacks until a Bitcoin ransom is paid. Consequently, there are now more attacks on more organizations worldwide than ever before. Akamai recently reported a year-over-year increase of 180% in the number of attacks it saw through its network.Not only are attacks becoming more frequent, they are getting larger, too. Some recent attacks have exceeded 200 million packets per second (Mpps). An event of this size is sufficient to bring down a tier 1 router, the kind often used by Internet Service Providers (ISPs).To read this article in full or to leave a comment, please click here

FBI, keep out! How to encrypt everything

The FBI’s inability to crack a terrorist’s iPhone 5c shows the strong protection you can get for your private information on a mobile device. That same encryption is also available on your computer, at least in some cases.Given the increasing access to personal and corporate data sought by the U.S. government, as well as by other politicians, unscrupulous businesses, and criminal hackers, people should up their game on what they protect. Fortunately, it's not hard to do. (But be sure to back up your data before you encrypt your devices, in case a power failure occurs during the encryption process and makes your data unavailable.)To read this article in full or to leave a comment, please click here
