Overcoming the Barriers to Micro-segmentation
It should come as no surprise how much emphasis organizations place on security today. Threats are becoming more and more sophisticated and the number of threats grow to uncontrollable rates every day.
One of the biggest downsides is that the rising cost of data breaches in 2019 alone, a global average of $3.92 million as reported by the Ponemon Institute and IBM Security July 2019 report, is enough to cause organizations to rethink or increase emphasis on their security strategies and how they can help secure their most important assets by improving the cyber hygiene in their organizations.
What is Cyber Hygiene?
Cyber hygiene refers to what an organization can do to improve their security postures around physical hardware, software, and applications. If you’ve seen Pat Gelsinger’s keynote from 2017, he goes into the 5 pillars of good cyber hygiene and what organizations can do to improve basic and fundamental security for their business.
Over the last several years, VMware has been focusing on helping organizations move to Software-Defined Data Centers (SDDC) to improve their agility and meet the speed of business. As more organizations adopted the SDDC model, VMware found itself in a unique position Continue reading
Real Life Financial Network Design – Multicast – BGP – EIGRP – Latency Design Considerations
I was in London last week for CCDE Training. During the training, there was a discussion on Financial network design and one of the students explained how they designed their financial world-wide network. We recorded the discussion and I think you will get great benefit if you want to understand how financial networks are designed, …

How Do You Provision a 500-Switch Network in a Few Days?
TL&DR: You automate the whole process. What else do you expect?
During the Tech Field Day Extra @ Cisco Live Europe 2019 we were taken on a behind-the-stage tour that included a chat with people who built the Cisco Live network, and of course I had to ask how they automated the whole thing. They said “well, we have the guy that wrote the whole system onsite and he’ll be able to tell you more”. Turns out the guy was my good friend Andrew Yourtchenko who graciously showed the system they built and explained the behind-the-scenes details.

In the previous posts, I covered the basics of connecting to NATS in Go and the different ways subscribers can request information is sent to them. In this post, I’d like to build on those concepts by exploring how to structure your NATS-powered Go code so that things are clean and DRY. I’ll also show that trying to make things too DRY can be problematic; as with everything, moderation is a good idea.Keeping NATS Connections DRY in Go

The establishment of Pu‘uhonua o Waimānalo in 1994 was a significant milestone in the native Hawaiian movement to regain independence from the United States, which overthrew its kingdom in 1893. The United States formally acknowledged its role in the overthrow of the Kingdom of Hawaii in a law adopted by Congress in 1993 known as the Apology Resolution. A quarter of a century later, the Nation of Hawai’i is levelling up with a new effort in the push for sovereignty: community-led Internet access.
The Nation of Hawai’i is excitedly gearing up for the upcoming build and launch of Hawai’i’s first independent community broadband network in our village of Pu`uhonua O Waimanalo on the island of O’ahu.
As an early adopter of the Internet, the Nation of Hawai’i quickly recognized its potential to support sovereignty and self-determination efforts.
In 1995, the Nation of Hawai’i launched hawaii-nation.org as a way to share its history and updates about current initiatives with the world. The website housed extensive primary-source historical documents, including the constitutions and treaties of the Hawaiian Kingdom. It hoped that by providing access to lesser known parts of history, Hawaiians and supporters around the world could learn and make up Continue reading

The Week in Internet News: China and Russia Target ‘Illegal’ Content
Content crackdown: China and Russia plan to sign an agreement to crack down on what they consider “illegal” Internet content, The Register reports. It’s unclear what the agreement will cover but critics already fear the deal will enable the two countries to further crack down on free speech. China has even effectively banned cartoon character Winnie the Pooh because some people have compared the chubby bear to leader Xi Jinping.
Eyes on you: In more censorship-related news, Thailand has ordered restaurants and Internet cafes to log the Internet histories of users, Privacy News Online says. The Thai government already requires ISPs to keep a log of customers’ Internet histories for 90 days as part of the country’s Computer Crimes Act.
Poor access: Some of the U.S. states with the lowest levels of broadband access also have the highest poverty rates, notes a report from Axios. About 30 percent of low-income U.S. residents do not have access to broadband, says the story, citing a Census Bureau report.
Not so smart: A new “smart” doorbell may literally unlock a home’s doors to hackers, according to The Daily Swig. A security researcher found that the Wi-Fi connected doorbell had no authentication Continue reading

SEC 1. Data plane and control plane protection in the networking (Nokia, Cisco and Mellanox/Cumulus) for IPv4.
Hello my friend,
This is the third article where we use the Mellanox SN 2010 running Cumulus Linux. And today we cover enormously important topic: network security. More precisely, we will speak about the data plane and the control plane protection. Cisco IOS XR and Nokia SR OS accompany us in this journey.
Thanks
Special thanks for Avi Alkobi from Mellanox and Pete Crocker and Attilla de Groot from Cumulus Networks for providing me the Mellanox switch and Cumulus license for the tests.
Disclaimer
This blogpost is the continuation of the previous one, where we have brought the Mellanox SN 2010 to the operational with Cumulus Linux 3.7.9 on board. If you want to learn the details about this process, you are welcomed to read that article.
Brief description
Each week you can find the news describing the security breaches. In the modern economy, where the Internet plays already a key role, all the connected businesses (and almost all businesses are connected) are on the risk caused by casual network scanning and brood force attacks. In addition to that, big companies and governments are quite often the attack targets for other companies, governments and criminals. Therefore, Continue reading
New Content: EVPN on Linux Hosts and External Azure Connectivity
Dinesh Dutt added another awesome chapter to the EVPN saga last week explaining how (and why) you could run VXLAN encapsulation with EVPN control plane on Linux hosts (TL&DR: think twice before doing it).
In the last part of current Azure Networking series I covered external VNet connectivity, including VNet peering, Internet access, Virtual Network Gateways, VPN connections, and ExpressRoute. The story continues on February 6th 2020 with Azure automation.
