The Truth About Cybersecurity Certifications

It’s a common trait amongst cybersecurity professionals.  When they meet each other, discuss their qualifications with prospective employers, or print their business cards, there is often an alphabet soup of initials by their names, specifying the many certifications they’ve achieved.Now some of these certifications are certainly worthwhile but over the last few years, the entire industry has gone gaga with dozens of new cybersecurity certifications offered by for-profit organizations.  This has led to a marketing push with a consistent message that more certifications equate to more money, knowledge, and opportunities for cybersecurity professionals.To read this article in full or to leave a comment, please click here

Legacy TLS cipher support in Firefox

After upgrading Firefox recently, I noticed that I could no longer access certain embedded devices via HTTPS. It seems that recent versions of Firefox and Chrome no longer support certain TLS ciphers due to recently discovered vulnerabilities. That's all well and good, except the error returned offers no recourse if you need to connect anyway.

firefox_error.png

Firefox returns the error SSL_ERROR_NO_CYPHER_OVERLAP with no option to temporarily allow connectivity. (Chrome reports a similar error named ERR_SSL_VERSION_OR_CIPHER_MISMATCH.) Presumably, this choice was made by the developers with the intention of forcing people to upgrade outdated devices. Unfortunately, in order to upgrade an out-of-date device, we typically must first be able to connect to it. I wasted a fair bit of time digging up a solution, so I figured I'd document the workaround here for when I inevitably run into this problem again a year from now and have forgotten what I did.

5 affordable MDM options for small businesses

Affordable MDM options for small businessesImage by ThinkstockSmall and medium sized businesses (SMBs) have embraced BYOD. In a study of SMBs from the IT community, Spiceworks, 61 percent of respondents said they have a BYOD policy in place. However, the same study found that 56 percent of that group also said they had not implemented any mobile device management (MDM) strategies and didn't have plans to do so within the next six months. While BYOD might allow these smaller businesses to save on hardware costs, it does open up unique risks for IT. With employees running on varying operating systems and hardware, it becomes difficult to implement secure solutions across the board, leaving sensitive data at risk. If just one employee's tablet falls into the wrong hands, you're going to wish you had some way to remotely wipe data on that device. But small businesses also have small IT departments -- sometimes consisting of only one person -- so a BYOD management strategy needs be straightforward, affordable and low-maintenance. Just because your business doesn't have a big budget or a large staff doesn't mean you can't ensure that all your corporate data remains secure, no matter where Continue reading

IDG Contributor Network: 8 tech ‘megatrends’ that are about to change business

An assemblage of technological breakthroughs are rapidly morphing to create massive changes in how businesses operate.Artificial intelligence (AI), blockchain and Internet of Things (IoT) are just three of eight crucial “megatrends” that strategy consulting firm PricewaterhouseCoopers (PwC) says is going to significantly distort business.Those new forces should clearly be planned for. And although the consulting firm's advice is aimed at generalized CEOs, it's IT and technical teams that will have to lay the groundwork.Robots, augmented reality (AR), 3D printing, drones and virtual reality (VR) are also among PwC’s pick of “essential eight technologies” that the firm says in its report (PDF) (released during the summer) need to be considered by company chiefs to move their operations forward.To read this article in full or to leave a comment, please click here

Lawmakers want UK to set example on transparency in AI decision making

British lawmakers want more transparency and less bias in decision-making -- not their own, of course, but in decisions made by AI systems.As more and more software systems and connected devices employ artificial intelligence technologies to make decisions for their owners, the lawmakers want to know what's behind their thinking. The U.K. Parliament's Science and Technology Committee has been studying the need for more regulation in the fields of robotics and artificial intelligence.Recent advances in AI technology raise a host of social, ethical and legal questions, the committee's members said in a report published Wednesday.To read this article in full or to leave a comment, please click here

Reaction: DNS is Part of the Stack

Over at ipspace.net, Ivan is discussing using DNS to program firewall rules—

Could you use DNS names to translate human-readable rules into packet filters? The traditional answer was “no, because I don’t trust DNS”.

This has been a pet peeve of mine for some years—particularly after my time at Verisign Labs, looking at the DNS system, and its interaction with the control plane, in some detail. I’m just going to say this simply and plainly; maybe someone, somewhere, will pay attention—

The Domain Name System is a part of the IP networking stack.

Network engineers and application developers seem to treat DNS as some sort of red-headed-stepchild; it’s best if we just hide it in some little corner someplace, and hope someone figures out how to make it work, but we’re not going to act like it should or will work. We’re just going to ignore it, and somehow hope it goes away so we don’t have to deal with it.

Let’s look at some of the wonderful ideas this we’ll just ignore DNS has brought us over the years, like, “let’s embed the IP address in the packet someplace so we know who we’re talking to,” and “we Continue reading

Lessons Learned from Scaling Uber to 2000 Engineers, 1000 Services, and 8000 Git repositories

For a visual of the growth Uber is experiencing take a look at the first few seconds of the above video. It will start in the right place. It's from an amazing talk given by Matt Ranney, Chief Systems Architect at Uber and Co-founder of Voxer: What I Wish I Had Known Before Scaling Uber to 1000 Services (slides).

It shows a ceaseless, rhythmic, undulating traffic grid of growth occurring in a few Chinese cities. This same pattern of explosive growth is happening in cities all over the world. In fact, Uber is now in 40 cities and 70 countries. They have over 6000 employees, 2000 of whom are engineers. Only a year and half a go there were just 200 engineers. Those engineers have produced over 1000 microservices which are stored in over 8000 git repositories.

That's crazy 10x growth in a crazy short period of time. Who has experienced that? Not many. And as you might expect that sort of unique, compressed, fast paced, high stakes experience has to teach you something new, something deeper than you understood before.

Matt is not new to this game. He was co-founder of Voxer, which experienced its Continue reading
