IDG Contributor Network: Wi-Fi-based positioning improves access point security

Imagine if your router could detect a user’s location to within a few inches? For one thing, hotspot password protection becomes redundant because geographic authentication takes over—the router can be configured to only allow access from within a location, an apartment, say. In-café users could be allowed access without passwords, yet freeloaders on the street get blocked.Researchers think they’ve worked out how to do it.The system “locates users by calculating the ‘time-of-flight’ that it takes for data to travel from the user to an access point,” says Adam Conner-Simons in a recent MIT News article. And it does it with a single access point. That’s unlike other setups that require four or five access points for triangulation-like measuring. One access point determining a user’s position means costs should be lower, and individuals or small businesses can take advantage of the tech.To read this article in full or to leave a comment, please click here

Consumers want more value from home IoT products

U.S. consumers are slow to embrace home-based Internet of Things products, with many wary of their cost and usefulness, according to a new survey.Many consumers are skeptical about the value proposition behind home IoT products, according to the survey from market research firm IDC.Reliability was the top concern among those people who expressed interested in home IoT devices. On a one to 10 rating scale, reliability rated nearly a nine when people were asked what home IoT issues needed to improve before they would purchase a system.Following close behind were concerns about cost, with equipment costs, ongoing costs, installation costs, overall value, all scoring above 8.75. Ease of use and security or privacy concerns were also major concerns.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Sysdig and Mesosphere partner to monitor all of those containers

A new partnership being announced today sees Sysdig and Mesosphere getting cozy to enable a more consistent way of developing and delivering applications.These are two interesting vendors in different spaces. Sysdig calls itself a "container visibility company." Essentially what that means is that it offers a container-specific monitoring solution. One can think of it like New Relic and Boundary but with containers as a primary focus. Mesosphere, on the other hand, is the company that commercializes the Mesos open-source project to help scale and automate applications. Mesosphere offers the data center operating system (DCOS), which delivers a simpler administration model for data center operators.To read this article in full or to leave a comment, please click here

Ahead of Google I/O, Google previews new Android N Multi-Window support

Google released more information about Android N (referring to N as Not the real name). The preview of the mobile operating system gives the impression of a more in-depth system and user-level polish that has been Google’s obsession since Android 4.4 Kitkat.Multi-Window Support Multi-Window support stands out as the most important feature for users, consumers and developers. It allows apps to be opened in two separate windows and used on a split-screen display. User interest in Multi-Window has become increasingly important as mobile devices replace PC apps with mobile apps. When work moves to a mobile app, users want many of the same PC features, keyboards, split screens, drag and drop, etc.To read this article in full or to leave a comment, please click here

Serial numbers how I love thee…

No one really like serial numbers, but keeping track of them is one of the “brushing your teeth” activities that everyone needs to take care of. It’s like eating your brussel sprouts. Or listening to your mom. You’re just better of if you do it quickly as it just gets more painful over time.

Not only is it just good hygene, but you may be subject to regulations, like eRate in the United States where you have to be able to report on the location of any device by serial number at any point in time.

Trust me, having to play hide-and-go seek with an SSH session is not something you want to do when government auditors are looking for answers.

I’m sure you’ve already guessed what I’m about to say, but I”ll say it anyway…

There’s an API for that!!!

HPE IMC base platform has a great network assets function that automatically gathers all the details of your various devices, assuming of course they supportRFC 4133, otherwise known as the Entity MIB. On the bright side, most vendors have chosen to support this standards based MIB, so chances are you’re in good shape.

And if they don’t Continue reading

5 things you should know about the blockchain

Talk of blockchain technology is everywhere, it seems -- but what is it, and what does it do?1. Don't call it "the" blockchainThe first thing to know about the blockchain is, there isn't one: there are many. Blockchains are distributed, tamper-proof public ledgers of transactions. The most well-known is the record of bitcoin transactions, but in addition to tracking cryptocurrencies, blockchains are being used to record loans, stock transfers, contracts, healthcare data and even votes.2. Security, transparency: the network's run by usThere's no central authority in a blockchain system: Participating computers exchange transactions for inclusion in the ledger they share over a peer-to-peer network. Each node in the chain keeps a copy of the ledger, and can trust others’ copies of it because of the way they are signed. Periodically, they wrap up the latest transactions in a new block of data to be added to the chain. Alongside the transaction data, each block contains a computational "hash" of itself and of the previous block in the chain.To read this article in full or to leave a comment, please click here

Learning about SDP via Google BeyondCorp

I’ve been following Google’s BeyondCorp project for a while.  In fact, I was recently quoted in a Wall Street Journal blog on this topic. If you are not familiar with BeyondCorp, it is Google’s spin on what’s become known as a software-defined perimeter (SDP).  SDP, also called a “black cloud” originated at the Defense Information Systems Agency (DISA) and is now being driven by the Cloud Security Alliance (CSA).  To read this article in full or to leave a comment, please click here

Minimizing cost of visibility

Visibility allows orchestration systems (OpenDaylight, ONOS, OpenStack Heat, Kubernetes, Docker Storm, Apache Mesos, etc.) to adapt to changing demand by targeting resources where they are needed to increase efficiency, improve performance, and reduce costs. However, the overhead of monitoring must be low in order to realize the benefits.
An analogous observation that readers may be familiar with is the importance of minimizing costs when investing in order to maximize returns - see Vanguard Principle 3: Minimize cost
Suppose that a 100 server pool is being monitored and visibility will allow the orchestration system to realize a 10% improvement by better workload scheduling and placement - increasing the pool's capacity by 10% without the need to add an additional 10 servers and saving the associated CAPEX/OPEX costs.

The chart shows the impact that measurement overhead has in realizing the potential gains in this example. If the measurement overhead is 0%, then the 10% performance gain is fully realized. However, even a relatively modest 2% measurement overhead reduces the potential improvement to just under 8% (over a 20% drop in the potential gains). A 9% measurement overhead wipes out the potential efficiency gain and measurement overheads greater than 9% result in Continue reading

22 insults no developer wants to hear

The technology world is a bit different than the pretty, coiffed world of suits and salesdroids where everyone is polite, even when they hate your guts and think you’re an idiot. Suit-clad managers may smile and hide their real message by the way they say you’re doing “great, real great pal,” but programmers often speak their minds, and when that mind has something unpleasant to say, look out, feelings.Parsing, unpacking, and sorting the insults that developers sling takes a thick skin. No one likes being told their ideas and code are anything less than insanely great, but some slights are better than others, cutting to the core of your coding faults. In fact, a good insult can contain a road map for moving your project forward. If your rival is willing to explain what you need to do to make your code worth using, well, that’s worth putting up with someone calling you or your code “heavy,” “crufty,” or “full of anti-patterns.”To read this article in full or to leave a comment, please click here

Are IT executives blind to cybersecurity threats?

Is your company’s cybersecurity keeping you up at night?If you're an IT professional, the answer to that question is probably yes. If you're an IT executive, the answer to that question might be no – even if you work at the same company.What we're seeing, says Jack Danahy, co-founder of Barkly, a Boston-based endpoint security startup company, "is a breakdown in communication."That's what Barkly found in its "Cybersecurity Confidence Report." In it, Barkly surveyed of 350 IT professionals and found that 50 percent are not confident in their current security products or solutions.To read this article in full or to leave a comment, please click here

4 biggest misconceptions about hiring data scientists

When you think of the perfect candidate for a data science role, a few preconceived notions come to mind. You want someone who is analytical, detail-oriented and intuitive -- all important qualities in a data scientist. But there is more to data science than being good with numbers -- the core of a data scientist's role involves influencing decision-makers within the business and guiding the future of the company.While there are a lot logical traits that make a good data scientist, there are plenty of skills data scientists need that don't fall under the category of data. Ziad Nejmeldeen, senior vice president and chief scientist at the Infor Dynamic Science Labs, knows this better than anyone, having hired his own data scientists and helped guide the data strategies of numerous businesses at Infor. If you hold common misconceptions about data scientists, it might be time to reevaluate your strategy, according to Nejmeldeen.To read this article in full or to leave a comment, please click here

3 ways IoT security concerns are taken out of context

This Saturday was like most every other day for me.  I opened my  RSS Internet of Things (IoT) news feed and there were three more articles telling me that consumers don’t trust IoT security.  IoT security alerts have been so frequent and regular for so long now that just like a “check engine light” in an old car I am beginning to ignore them.  Recently I have seen a slight pivot in the stream of warnings in the form of survey data:  Data is good.  More than once I have heard “In God we trust” all others bring data.  But data requires analysis so let’s look at a few recent figures:To read this article in full or to leave a comment, please click here

5 career-killing conversations to avoid at work

No matter how progressive, open and casual your workplace, there are some conversations that should be off-limits no matter what. A new study from corporate and leadership education and training firm VitalSmarts found that of 775 respondents to a recent VitalSmarts survey on workplace behavior, 83 percent of employees witnessed their colleagues say something that has had catastrophic results on their careers, reputations and businesses.To read this article in full or to leave a comment, please click here
