Repost: Tony Przygienda on Valley-Free (or Non-ZigZag) Routing
Most blog posts generate the usual noise from the anonymous peanut gallery (if only they'd have at least a sliver of Statler and Waldorf in them), but every now and then there's a comment that's pure gold. The one made by Tony Przygienda (of RIFT fame) on Valley-Free Routing post is so good and relevant that I decided to republish it as a separate blog post. Enjoy!

I run my labs on an Ubuntu 1604 host using KVM for the hypervisor and some of the network VM images (Cisco CRS1000v, Juniper vMX, etc..) run with very high CPU.

Did the passage of gDPR impact the amount of spam on the ‘net, or not? It depends on who you ask.
The folks at the Recorded Future blog examined the volume of spam and the number of registrations for domains used in phishing activity, and determined the volume of spam was not impacted by the implementation of Europe’s new privacy laws.
To understand the effect of GDPR, the relevant questions are: Is GDPR enabling damage, because it makes detection, blocking, and mitigation harder?
Note that the CircleID article only addresses the domain registration question, and does Continue reading

We Need a Common Language for the Internet of Things
When someone tells me they have bought smart light bulbs, an Internet-connected pet cam, or any other Internet of Things (IoT) device, I always get an unsettled feeling in the pit of my stomach. They’re so excited about the affordances or their new IoT devices and apps, but I am skeptical about the privacy and security vulnerabilities. How do I have a conversation about these concerns without coming across as hyper paranoid? Perhaps the answer is that we aren’t quite ready to discuss these issues on a societal level.
Privacy and security advocates all over the world have been talking about the threats that IoT may pose to society – unless standards and regulations are put in place to help mitigate some of these risks. They champion that privacy and security should be built into design and should not come as an afterthought.
While I praise the work that advocates are doing, IoT devices are on the shelves right now and we need to be able to have conversations with everyday folk about what privacy and security risks look like in the digital economy. However, how can we have these conversations when we haven’t yet established understandable and common terms Continue reading
A Review of Ubiquiti Wireless
About six months ago, I got fed up with my Meraki MR34 APs. They ran just fine, but they needed attention. They needed licenses. They needed me to pay for a dashboard I used rarely but yet had to keep up yearly. And that dashboard had most of the “advanced” features hidden away under lock and key. I was beyond frustrated. I happen to be at the Wireless LAN Professionals Conference (WLPC) and ran into Darrell DeRosia (@Darrell_DeRosia) about my plight. His response was pretty simple:
“Dude, you should check out Ubiquiti.”
Now, my understanding of Ubiquiti up to that point was practically nothing. I knew they sold into the SMB side of the market. They weren’t “enterprise grade” like Cisco or Aruba or even Meraki. I didn’t even know the specs on their APs. After a conversation with Darrell and some of the fine folks at Ubiquiti, I replaced my MR34s with a UniFI AP-AC-HD and an AP-AC-InWall-Pro. I also installed one of their UniFi Security Gateways to upgrade my existing Linksys connection device.
You may recall my issue with redundancy and my cable modem battery when I tried to install the UniFi Security Gateway for Continue reading
