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 70^th 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

Big Cloud Fabric Underlay Automation for VMware Cloud Foundation

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:

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

With Rome, AMD Will Build Off Momentum For Naples Epyc Chips

AMD had been down this road before. In 2003, the chip maker launched the “SledgeHammer” Opteron, the first 64-bit X86 server processor with backward compatibility to its 32-bit predecessors that came at a time when much larger rival Intel was still pumping up Itanium as the next-generation architecture – and its only 64-bit option. …

In this podcast we have an in-depth conversation about the different types and levels of innovation in the data center and where we see it going. Spiderman aka Rama Darbha and host Brian O’Sullivan are joined by a new guest to the podcast, VP of Marketing Ami Badani. They share that while innovation in the data center doesn’t appear sexy, outside of network engineers, in reality there has been a huge paradigm shift in the way data centers have built and operated last 3 years. So what does that mean? How is automation involved in this conversation? Listen here to find out.

A data-transmission revolution is underway

Radical data communications technologies are in development in a slew of academic scientific labs around the world. While we’ve already seen, and gotten used, to a shift from data sent being over copper wire to light-based, fiber-optic channels (and the resulting capacity and speed increases), much of the thrust by engineers today is in the area of semiconductor improvements, in part to augment those pipes.The work includes a potential overall shift to photons and light, not wires on chips, and even more revolutionary ideas such as the abandonment of not only silicon, but also the traditional electron.To read this article in full, please click here

Save the Date: 4th Summit on Community Networks in Africa

The 4th Summit on Community Networks (CNs) in Africa will take place in Dodoma, Tanzania from 28 October to 2 November 2019. The Summit hopes to promote the creation and growth of CNs, increase collaboration between CN operators in the region, and provide an opportunity for them to engage with other stakeholders.

The main activities planned include:

Training Workshop: 28-29 October
CN Summit Plenary: 30-31 October
Site Visit to Kondoa Community Network: 1-2 November

The event is targeted at CN operators, policy makers, researchers, evangelists, sponsors, and related networks such as community radio.

Last year over 100 participants from 20 countries, 13 of them African, gathered in Wild Lubanzi, in one of the deepest rural areas of the Eastern Cape. The 3^rd Summit on CNs in Africa was organized by the Internet Society,Zenzeleni Networks NPC, and APC from 2-7 September 2018. For the approximate 40 participants from surrounding communities, the Summit was their first international conference – or conference of any kind. It was exciting to see them absorb everything and feel proud of their neighbors in Mankosi, home of the Zenzeleni project, one of many community networks in Africa.

CNs offer local solutions to the connectivity Continue reading

How to manipulate PDFs on Linux

While PDFs are generally regarded as fairly stable files, there’s a lot you can do with them on both Linux and other systems. This includes merging, splitting, rotating, breaking into single pages, encrypting and decrypting, applying watermarks, compressing and uncompressing, and even repairing. The pdftk command does all this and more.The name “pdftk” stands for “PDF tool kit,” and the command is surprisingly easy to use and does a good job of manipulating PDFs. For example, to pull separate files into a single PDF file, you would use a command like this:$ pdftk pg1.pdf pg2.pdf pg3.pdf pg4.pdf pg5.pdf cat output OneDoc.pdf That OneDoc.pdf file will contain all five of the documents shown and the command will run in a matter of seconds. Note that the cat option directs the files to be joined together and the output option specifies the name of the new file.To read this article in full, please click here
