Russian hackers accessed White House email, report says

Hackers working for the Russian government were able to access President Obama’s email system inside the White House, CNN reported Tuesday, indicating that an earlier breach may have been more serious than previously thought.The State Department and the White House said late last year they had seen suspicious activity in their networks, though the White House said at the time only unclassified systems were affected. That may have been true, but it understated the sensitivity of the information accessed, CNN reported Tuesday, citing unnamed U.S. officials briefed on the investigation.To read this article in full or to leave a comment, please click here

Starting OVSDB and vSwitchd in OpenvSwitch with Debugging Enabled

Here are some quick notes on how I went about debugging OVSDB (ovsdb-server) and OVS vSwitchd (ovs-vsctl). There are lots of ways to debug OVS these are what I used to get debug logs generated. Those logs are helpful troubleshooting for OVSDB transactions and OpenFlow commands when using the ovs-vctl or OVSDB and OpenFlow APIs. Dont do this unless you ...

Apple Watch orders to be limited to one per customer

Apple Watch pre-orders open up this Friday at 12:01 AM Pacific Time. In anticipation of what might very well be staggering demand, Apple has reportedly limited pre-orders of the device to just one per customer as it pertains to in-store pickup. Presumably, users who order the device to their homes can order more than one at a time.MacRumors was the first to relay the news early on Tuesday morning in the form of a message that will purportedly be sent to those who make pre-orders this Friday for in-store pickup on April 24.. Inventory is subject to change. Your reservation is valid for pickup only at the Apple Retail Store that you selected. If you do not pick up your selected item(s) by the designated date and time, your reservation will be cancelled and your item(s) will be returned to stock. There is a maximum of 1 reservation per customer. Number of reservations may be limited. Apple reserves the right to refuse, limit or cancel a reservation if Apple determines that a customer has provided misleading or fraudulent information and/or abused, disrupted or attempted to circumvent the reservation system.To read this article in full or to leave a Continue reading

How to use AnyConnect to “cheat” in the CCIE wireless lab

How would you like to be able to look up the answers to some of the tasks in the wireless lab, and not get in trouble over it? Well, read on, and I’ll give you a fun tip that you may be able to use in the lab to solve parts of certain lab tasks. It’s not actually cheating, but it almost feels like it.

One of the realities of the lab is that there will be some pre-configurations on many of the devices. You won’t be configuring every last device from scratch. There’s not enough time, and they’d prefer to test you on more complex things than configuring every VLAN, interface, host name, etc from scratch. Just about anything has the potential to have some level of pre-configuration, and that includes the AnyConnect client. If you find that the AnyConnect client already has some WLAN profiles configured on it, say a silent “thank you” to Cisco because they just gave you a ton of great information.

Another reality of the lab is that they often don’t ask you to do things in the most straightforward and clear way possible. Often they use code words or phrases that need to Continue reading

HP tells cybersecurity customers to focus on people and processes

To protect themselves against cyberattacks, organizations should focus more on training their employees and improving their internal processes instead of buying new technology, according to one tech vendor.Yet, businesses and government agencies often focus on the next “silver bullet” product, unaware that most cybersecurity problems stem from flawed procedures and human error, said Art Gilliland, senior vice president and general manager for Hewlett-Packard’s software enterprise security products.“This is hard for a product guy to say out loud to an audience, but invest in your people and process,” Gilliland said at HP’s Software Government Summit in Washington, D.C. “The first thing that always gets negotiated out of every [security software] contract is the training and the services.”To read this article in full or to leave a comment, please click here

Welcome to the Internet of Things. Please check your privacy at the door.

It knows when you are sleeping and when you are awake. It knows when you're home and when you're away. It knows how how fast you drive, how many steps you took yesterday, and how hard your heart is working right now.It's the Internet of Things (IoT), and it is terrible at keeping secrets.INSIDER: 5 ways to prepare for Internet of Things security threats If the Web resembles the wild west when it comes to personal privacy, then the IoT is a jungle where only the fearless survive. While the privacy threats are similar, the stakes are much higher. Connected devices are collecting vast amounts of deeply personal information from our homes, our cars, and our bodies -- far more than any Web site possibly could. The kind of data that's being collected and what happens to it is governed almost entirely by privacy policies that virtually no one reads and few truly understand. Many IoT devices and apps have no privacy policy at all. And IoT security at this point in time is tissue thin, leaving your personal data at risk from external attack.To read this article in full or to leave a comment, please click here

Git for network engineers

What is Git?

git-logo

Git is a source control manager (SCM), also known as revision control. It manages changes to documents, computer programs and large websites. Arbitrarily it can manage versioning for collections of information.

Why is it important to network engineering? Well, currently we stick the config files in a directory and forget about them. Version control can be very regimented with commit comments and other markers, which helps to identify information. More importantly, as we move towards DevOps with open arms, we have to think about managing what we do in different ways. Just because something has been done a certain way, doesn’t mean it’s good to continue with that modus operandi.

Fear not – just because something is hidden away in a repository, doesn’t mean you can’t diff files etc.

Also you don’t have to have just local git repositories, you can have them on remote servers as well as the likes of github.com.

Before we start, be warned that this is a very simple example. You can use this for managing all sorts of configurations like core routers, firewall access-list entries, hell, even change control data. Be mindful of what you push and commit!!! Ensure that Continue reading

OCP Summit 2015: Open Networking as the Norm

Open Networking Thrives at the 2015 OCP Summit

A few weeks ago I passed my 2 year work anniversary at Cumulus Networks. In this short amount of time we’ve helped change the networking industry as a whole. This statement may seem a bit bold, but I feel it’s justified and we’ve all earned it. I’ll attempt to back this up with a few anecdotes collected along the journey — the men and women of Cumulus Networks, along with our great partners and customers, deserve the credit here.

When I was first hired, our on-boarding process was a bit … unconventional to say the least. The first week included JR (our CEO and cofounder) taking a headshot photo for the website (at that time it was just a Brady Bunch collage of pictures, not much else) and being issued a switch for “jailbreaking.” Now jailbreaking is a bit of an extreme term, but in these dark days before open networking, the software and hardware for networks were tightly coupled together. Items such as debugging headers, a soldering iron, and even a bit of swearing were all part of the installation process on a fresh hardware platform. Fast forward to today, Continue reading

Group fighting ‘Net censorship in China presses on despite DDoS attack

After facing a DDoS attack, an activist group isn’t backing down in its attempts to end China’s Internet censorship.“I think that we are more confident than we were before that our successful execution of our strategy is going to lead us to achieve our mission,” said the group via email on Tuesday.GreatFire.org suffered a distributed denial of service attack last month that threatened to cripple its activities. The anonymous group, which is based out of China, believes the country’s government was behind the attack.To read this article in full or to leave a comment, please click here

Apple, as Watch rollout looms, emphasizes online ordering

Apple is looking to eliminate the long lines that form outside its retail stores on product launch days.“The days of waiting in line and crossing fingers for a product are over for our customers,” according to a memo from Angela Ahrendts, Apple’s senior vice president of retail and online stores, that was obtained by Business Insider.The memo instructs Apple’s retail employees to encourage customers interested in either the Apple Watch or new MacBook to order the products online instead of from the stores.To read this article in full or to leave a comment, please click here

That’s Using Your Embrane

BrainInABox

Cisco announced their intent to acquire Embrane last week. Since they did it on April 1st, there was an initial thought that it might be a prank. But given that Cisco doesn’t really do April Fools jokes, it was quickly determined to be the real deal. More importantly, the Embrane acquistion plugs a very important hole in ACI that I have been worried about for a while.

Everybody Play Nice

Application Centric Infrastructure (ACI) is a great idea that works on the principle that Cisco can get multiple disparate systems to work together to “program” the underlying network to rapidly deploy applications and create policies that allow systems to be provisioned and reconfigured with a minimum of effort.

That’s a great idea in theory. And if you’re only working with Cisco gear it’s any easy thing to pull off. Provided you can easily integrate the ASA operating system with IOS and NX-OS. That’s not an easy chore and all those business units work for the same company. Can you imagine how hard it would be to integrate with an external third party? Even one that is friendly to Cisco? What about a company that only implements the bare minimum functionality Continue reading
