Review: More sleep-related devices to help you get more ZZZs

The month of May has been dedicated “Better Sleep Month” by the Better Sleep Council. If you don’t like that group and you prefer to follow the guidelines of the National Sleep Foundation, you just celebrated Sleep Awareness Week (April 23-29, 2017). Either way, there’s no better time to look at some new products that want to help you get a better night’s sleep.I’ve previously written about two other devices – the ASTI Sound+Sleep SE sound machine, which provides 64 different sounds to help provide a white-noise-like effect; and the LIVE sensor by EarlySense, which tracks your heartbeat, breathing, stress levels and sleep stages to give you data about how much (or how little) you’re sleeping.To read this article in full or to leave a comment, please click here

IoT Security Anti-Patterns

IoT Security Anti-Patterns

From security cameras to traffic lights, an increasing amount of appliances we interact with on a daily basis are internet connected. A device can be considered IoT-enabled when the functionality offered by its Embedded System is exposed through an internet connected API.

Internet-of-Things technologies inherit many attack vectors that appear in other internet connected devices, however low-powered hardware-centric nature of embedded systems presents them with unique security threats. Engineers building Internet-of-Things devices must take additional precautions to ensure they do not implement security anti-patterns when addressing new problems, this blog post will investigate four such anti-patterns that have been used by real Internet-of-Things devices.

HTTP Pub/Sub

Every time your IoT-enabled alarm clock sounds, you may want it to tell your coffee machine to brew some coffee. In order to do this, your coffee machine may subscribe to messages published by your alarm clock. One such way of doing this is to implement the Publish/Subscribe Pattern within the API of the IoT devices, for this example let's assume our alarm clock and coffee machine communicate through HTTP.

In order to subscribe to messages from the alarm clock, the coffee machine sends Continue reading

Using the Collaborative Security Approach to Address Internet of Things Security Challenges

Two years ago, our “Collaborative Security Approach” proposed a way of tackling Internet security issues based on the fundamental properties of the Internet and the voluntary cooperation and collaboration that’s been prominent throughout the Internet's history. In this post, let us look at each of the five key Collaborative Security characteristics as they apply to security of the Internet of Things (IoT).

US bill aims to quash Open Internet Order, prevent its return

A bill introduced Monday by some U.S. senators aims to repeal net neutrality rules under the Federal Communications Commission’s 2015 Open Internet Order, and ban the agency from issuing similar regulations in the future.The legislation aims to give some permanence to recent moves by the Republican-dominated FCC to repeal provisions of the 2015 order. There are concerns that if the FCC at some point comes under the control of Democrats, it will promptly restore the rules under the 2015 Open Internet Order.The Restoring Internet Freedom Act was introduced by Senator Mike Lee, a Republican from Utah, and is cosponsored by eight other Republicans including Ted Cruz, senator for Texas, and Rand Paul, senator for Kentucky.To read this article in full or to leave a comment, please click here

Is IT having an identity crisis?

In 2007, Michael Spears became CIO of the National Council on Compensation Insurance. It wasn't the usual promotion. Spears had spent two years as the NCCI's chief data officer, and he kept that role when be became CIO. In his dual capacity, he oversees both the IT department and the data resources division, though they operate as separate entities. Over the years, he says, the CIO and CDO roles have sometimes been held by different people and sometimes by the same person.Spears has taken some ribbing for his CIO role from his colleagues in the data analytics world. "I was just at a data conference where people were making fun of me for being in both roles. They said, 'You can't get lumped in with IT — it's just bits and bytes. You won't be respected for the knowledge you have about data.' But it doesn't have to be that way. It depends where the value is coming from, the skill sets of the leaders, and what's important to the company at that time."To read this article in full or to leave a comment, please click here

SMBs continue to be a target of cybercriminals

Because they don’t see themselves as targets, small-to-midsize businesses (SMB) have for a long time believed that their security programs are good enough. They have a firewall, antivirus, maybe they even use two-factor authentication.The mistake is believing that this is enough because they have nothing of value to an attacker. While they may have a smaller attack surface, they are no less vulnerable than a major enterprise.Not only are small businesses growing as the favored targets for ransomware attacks, they are also the most impacted, with 60 percent shutting down within six months of a breach, according to the US National Cyber Security Alliance.To read this article in full or to leave a comment, please click here

Red Hat and IBM raise objections to Java 9 modularization

Modularization is slated to be the key feature in Java SE (Standard Edition) 9, due in late July. But Java participants Red Hat and IBM have raised concerns that the base module plan could lead to incompatibilities with applications and enterprise Java.In a recent bulletin, Scott Stark, vice president of architecture for Red Hat’s JBoss group, outlined a litany of issues Red Hat and other Java Executive Committee members have with JSR (Java Specification Request) 376, pertaining to the Java Platform Modular System, a central component of the Project Jigsaw module Java effort.To read this article in full or to leave a comment, please click here

Human weakness enabling financial cybercrime

It may be time for a revision of, “the customer is always right,” at least in the financial sector.That, Boston Police Detective Steven Blair told an audience of bankers at the Boston Fed’s 2017 Cybersecurity Conference on Monday, is because too many banking “customers” are fraudsters, who take advantage of the generally laudable desire of front-line employees to provide good customer service.Attendees had heard Kenneth Montgomery, first vice president and COO of the Boston Fed, say earlier that cybersecurity is now, “the number-one operational and enterprise issue” for the financial sector. He said the worldwide costs of cybercrime are estimated at $3 trillion annually now, and expected to double by 2021.To read this article in full or to leave a comment, please click here

Netdev 2.1 conference report

I attended the Netdev 2.1 Conference in Montreal from April 6 to 8. Netdev is a community-driven conference mainly for Linux networking developers and developers whose applications rely on code in the Linux kernel networking subsystem. It focuses very tightly on Linux kernel networking and on how packets are handled through the Linux kernel as they pass between network interfaces and applications running in user space.

In this post, I write about the three-day conference and I offer some commentary on the talks and workshops I attended. I grouped my comments in categories based on my interpretation of each talk’s primary topic. The actual order in which these topics were presented is available in the Netdev 2.1 schedule. The slides from the talks, workshops, and keynotes are posted under each session on the Netdev web site. Videos of the talks are available on the netdevconf Youtube channel.

Keynotes

Each day at the Netdev conference featured a keynote by a prominent member of the Linux networking community. Two of the keynotes covered higher-level views of Linux in the network in the enterprise, cloud, and the Internet of things. The other keynote covered details of the new eXpress Data Path Continue reading
