5 reasons to choose a managed SD-WAN and 5 reasons to think twice

Northgate Gonzalez Markets, a chain of grocery stores in southern California, was launching a fast-paced digital transformation initiative that required a complete revamp of its WAN infrastructure.Northgate was taking the bold step of eliminating its data center and moving around 500 servers’ worth of applications and data to the cloud. The old WAN topology of backhauling traffic from each of its 43 locations to a central data center via two T-1s had to be replaced with a direct, reliable, resilient, secure connection from each individual location to the cloud.

After evaluating the pros and cons of the do-it-yourself (DIY) option versus a managed service, Lewis decided that a managed approach was preferable for multiple reasons, with speed at the top of the list. “We had a compressed timeline,” he says. “We didn’t have the luxury of saying, Continue reading

Hacker Jeopardy, Wrong Answers Only Edition

Among the evening entertainment at DEF CON is "Hacker Jeopardy", like the TV show Jeopardy, but with hacking tech/culture questions. In today's blog post, we are going to play the "Wrong Answers Only" version, in which I die upon the hill defending the wrong answer.

The problem posed is this:
YOU'LL LIKELY SHAKE YOUR HEAD WHEN YOU SEE TELNET AVAILABLE, NORMALLY SEEN ON THIS PORT
Apparently, people gave 21, 22, and 25 as the responses. The correct response, according to RFC assignments of well-known ports, is 23.

A good wrong answer is this one, port 25, where the Morris Worm spread via port 25 (SMTP) via the DEBUG command.

But the real correct response is port 21. The problem posed wasn't about which port was assigned to Telnet (port 23), but what you normally see these days.

Port 21 is assigned to FTP, the file transfer protocol. A little known fact about FTP is that it uses Telnet for it's command-channel on port 21. In other words, FTP isn't a text-based protocol like SMTP, HTTP, POP3, and so on. Instead, Continue reading

Fast Friday- Black Hat USA 2019

I just got back from my first Black Hat and it was an interesting experience. It was crazy to see three completely different security-focused events going on in town all at once. There was Black Hat, B-Sides Las Vegas, and DEFCON all within the space of a day or so of each other. People were flowing back and forth between them all and it was quite amazing.

A wanted to share a few quick thoughts about the event from my perspective being a first timer.

  • The show floor wasn’t as bit as VMworld or Cisco Live, but it was as big as it needed to be. Lots of companies that I’ve heard of, but several more that were new to me. That’s usually a good sign of lots of investment in the security space.
  • Speaking of which, I talked to quite a few companies about a variety of analytics, telemetry, and insider threat monitoring solutions. And almost all of them had a founder from Israel or someone that was involved in the cybersecurity areas of the IDF. That’s a pretty good track record for where the investment is going.
  • The Vegas booth gimmicks never change. I think I’ve spent too Continue reading

Ulukhaktok: Community Networking in the (Far) North

In June of this year, I had the great privilege of traveling to Ulukhaktok, NWT, Canada to talk to community members about the possibility of building a new, local Internet service network. As a result of these meetings, and the incredibly driven individuals I met with in Ulu, this time next year, Ulukhaktok will be the proud owner of the far-most Northern community network in the world.

I left Washington, D.C. in the throes of summer – upper 80-degree weather and so humid you’d feel wet the second you stepped outside. Two days and five planes later I was in Ulukhaktok, a community of about 400 people on the 70th parallel. Summer there is a little different, and I explored the community amidst summer snow and 24-hour days.

I spent four days getting to know the community, and it wasn’t hard to understand the deep sense of community pride right away. Ulu is a beautiful, U-shaped town on the edge of the Arctic Ocean. It’s filled with people who will stop when they see a stranger, smile, and ask who you are and what you’re doing. And every time someone stopped, I told them about the Internet Society, Continue reading

Innovations in CBD And Hemp

Cannabidiol (CBD) and hemp have been known to be used in health supplements for humans and animals, as well as in various beauty products. Since the legalization of marijuana in many U.S. states, innovations in CBD and hemp products have become an acceptable and highly effective alternative to synthetic drugs for the treatment of many conditions including:

  • Chronic pain
  • Anxiety and depression
  • PTSD
  • Arthritis 
  • Sleep issues

While more studies need to be done, it is believed since CBD and hemp oil may help reduce inflammation in the body that it may help serve as treatment and preventions for such health issues as heart disease and diabetes. 

Innovative in CBD and hemp products for the treatment of dogs, specifically, may help to:

  • Reduce aggression
  • Relieve pain
  • Improve skin and coat appearance
  • Help reduce seizures

When CBD and hemp products do not offer a miracle cure, they have shown great promise in helping people who do not respond well to traditional drugs or who may simply not like the negative side effects for prescription drugs in treating certain medical conditions.

Keep in mind that most of the innovations in CBD and hemp are not designed to make you high, Continue reading

Introducing Certificate Transparency Monitoring

Introducing Certificate Transparency Monitoring
Introducing Certificate Transparency Monitoring

Today we’re launching Certificate Transparency Monitoring (my summer project as an intern!) to help customers spot malicious certificates. If you opt into CT Monitoring, we’ll send you an email whenever a certificate is issued for one of your domains. We crawl all public logs to find these certificates quickly. CT Monitoring is available now in public beta and can be enabled in the Crypto Tab of the Cloudflare dashboard.

Background

Most web browsers include a lock icon in the address bar. This icon is actually a button — if you’re a security advocate or a compulsive clicker (I’m both), you’ve probably clicked it before! Here’s what happens when you do just that in Google Chrome:

Introducing Certificate Transparency Monitoring

This seems like good news. The Cloudflare blog has presented a valid certificate, your data is private, and everything is secure. But what does this actually mean?

Certificates

Your browser is performing some behind-the-scenes work to keep you safe. When you request a website (say, cloudflare.com), the website should present a certificate that proves its identity. This certificate is like a stamp of approval: it says that your connection is secure. In other words, the certificate proves that content was not intercepted or Continue reading
