Network Break 68: Juniper Firewall Burned, 2015 In Review

Network Break 68 looks at Juniper's ScreenOS vulnerabilities, analyzes NetApp's acquisition of SolidFire, and cheers Apple for opposing U.K. surveillance. Lastly, we review of some of our favorite stories from 2015, and a list of things we probably won't care about next year. Probably.

The next wave of cybercrime will come through your smart TV

Smart TVs are opening a new window of attack for cybercriminals, as the security defenses of the devices often lag far behind those of smartphones and desktop computers. Running mobile operating systems such as Android, smart TVs present a soft target due to how to manufacturers are emphasizing convenience for users over security, a trade-off that could have severe consequences. Smart TVs aren't just consumer items, either, as the devices are often used in  corporate board rooms. Sales of smart TVs are expected to grow more than 20 percent per year through 2019, according to Research and Markets. While attacks against smart TVs are not widespread yet, security experts say it is only a matter of time before cybercriminals take note of the weaknesses.To read this article in full or to leave a comment, please click here

Dual Core Network Design

Dual core design, also known as dual plane or disjoint plane topologies, refers to a highly redundant network chosen by companies whose main objective is to improve the resiliency of their network. Created using different data planes, dual core design is implemented by companies that receive the service from the different service providers. Put simply, […]

New Chinese law takes aim at encryption

A new law passed by China's Parliament on Sunday requires technology companies to assist the government in decrypting content, a provision that the country maintains is modeled after Western law. ISPs and telecommunication companies must provide technical assistance to the government, including decrypting communications, for terrorism-related investigations, according to Xinhua, China's official news agency. Xinhua quoted Li Shouwei, of the National People's Congress Standing Committee legislative affairs commission, as saying the law doesn't require technology companies to install "backdoors," the term for code that would give security agencies consistent, secret access to data, in software.To read this article in full or to leave a comment, please click here

The Network Automation Book

From OpenFlow to Software Defined Networking (SDN), there has been a lot of hype, 100s of millions of dollars in venture funding, and billions in exits within the network industry over the past 5+ years. The one thing we know for certain about the industry in all of this is that change is here, and more is coming, which is exactly the reason for this post!

Ironically, I also started this blog 5+ years ago. In the beginning, this blog was a lot of speculation around OpenFlow and the future of Software Defined Networking (SDN). Nowadays, it’s rare to hear me mention SDN at all, and the focus is much more practical on tools and technology that can help solve real problems. For those that have been reading for a while, you probably saw this shift in addition to the career shift I made 18+ months ago. These shifts go hand in hand with a new project I’ve been working on.

It’s with great pleasure that I’m finally able to announce a project that started several months ago that falls in-line with exactly the same topics you read about frequently on this blog.

What is the Project?

It’s a book! Continue reading

Training the Next-Generation Network Engineer

The networking industry is at a crossroads. In the past few years, we’ve seen a flurry of activity in the world of software-defined networking (SDN), but this has mostly just resulted in a bunch of new products. I don’t feel that this has done nearly enough to improve network operations. In fact, this has in many ways resulted in more complexity.

What we desperately need more than shiny new products (hardware or software) is a better understanding of simple tools and open source software. We need to be willing to take more direct control over our infrastructure, instead of relying on a vendor and their support contracts to solve all our problems. While vendors should still serve a critical role in operating a network, I feel strongly that now more than ever, end-users have the power to really own their own management layer, and the roadmap for how their organizations offer network services to the teams that run (and in some cases develop) applications for the business.

To that end, I’ve been spending the past six months or so ramping up my own personal efforts at helping the network community as a whole to start this journey. These simple contributions Continue reading

OED Tools: 1Password

The problem Security today is a main concern for every computer user. One of the first problem is how to manage password. I see many creative solutions around: post-it or paper only, use of the same password for all services, a spreadsheet inside an encrypted zip file… none of them appear safe or efficient. The […]

How to Talk to Your Parents About Encryption

It’s December 25th, which means most of you are probably at home visiting with family. I asked a few of the security engineers here at CloudFlare how they explain their jobs when they’re home for the holidays, and most of them responded with something along the lines of, "Oh, I stopped trying to do that a long time ago." Apparently, working in the cryptography field doesn’t exactly make it easy to talk about work with your parents.

After chatting with our crypto experts some more, we figured out a decent way to explain the general idea of encryption and why it’s a critical part of the Internet. While this post may not explain exactly what security engineers do on a day-to-day basis, hopefully it will help you at least tell your parents why you have a job in the first place.

Banks and Their Big Fancy Buildings

To explain encryption to your parents, I’d start by asking them why they trust their bank. Let’s say they have some cash to deposit. They drive to their bank’s local branch, walk through a big fancy lobby, wait in line for a teller, and hand them their money. It may seem like Continue reading
