IDG Contributor Network: New IDC report forecasts huge growth for IoT

In case you’re still not sure about the viability of the Internet of Things (IoT) as a business concept, some new findings from research firm International Data Corp. (IDC)—predicting significant growth for the market in the coming years—should be convincing.In addition to a rise in investments in IoT products and services, the IDC research describes how software and services will play a major role in the success of IoT project.According to the IDC study, worldwide spending on the IoT is forecast to reach $772.5 billion in 2018. That represents an increase of 15% over the $674 billion that will be spent on IoT in 2017. The new update to the firm’s Worldwide Semiannual Internet of Things Spending Guide forecasts worldwide IoT spending to sustain a compound annual growth rate (CAGR) of 14% through the 2017-2021 forecast period, surpassing the $1 trillion mark in 2020 and reaching $1.1 trillion in 2021.To read this article in full, please click here

IDG Contributor Network: Mega increase in cloud adoption underway

No matter how you look at it, the cloud is growing fast.To compare the market’s growth to the rest of IT, cloud computing is expanding seven times faster than non-cloud computing, according to a report from IDC released on February 21.To gauge the business decision-maker, the State of the cloud Survey gives us a good sense of how adoption decisions are changing, along with other internal insights. The 2017 version of the poll, based on the responses of 1,002 IT executives, found that the concerns related to cloud that have held back a higher degree of adoption are taking a nosedive. While 32% listed lacking expertise and resources as a top challenge last year, that number dropped to 25% this year.To read this article in full, please click here

Can IoT help make the enterprise more secure?

It’s no secret that the rise of the Internet of Things (IoT) presents massive new security challenges. Heck, I’ve written about the issue here more than once. But one company claims that enterprise IoT also shows promise for addressing key security issues.Also on Network World: Is the U.S. finally about to take IoT security seriously? and The time to deal with IoT security is now Tim Lang, CTO at BI and data analytics firm MicroStrategy, notes that 70 percent of security breaches come from the inside, and he says Enterprise Internet of Things (EIoT) can help enterprises “monitor and prevent these breaches before they happen.” To read this article in full, please click here

IoT Security Using BLE Encryption

Microsoft: ReFS is ridiculous

I’ve blogged before about how the new integrity-checking filesystem in Windows, ReFS, doesn’t actually have integrity checking turned on by default. It’s pretty silly that for a modern filesystem meant to compete with ZFS and BtrFS, to have the main 21st century feature turned off by default. But it’s not quite ridiculous. Not yet.

Now it turns out that scrubbing is only supported on Windows Server

1. Microsoft honestly shipped an integrity-checking filesystem in Windows 10 with no way to repair or scrub it.

I used to say that Windows 10 is the best Windows ever, and that Microsoft kinda won my trust back. But what the hell?

I contacted Microsoft support over chat, who first suggested I do a system restore (sigh). But after I insisted that they please confirm that it’s supposed to work confirmed that no that only ships with Windows Server.

It’s not even clear from their pricing if I need the $882 Standard Edition or the $6,155 Datacenter Edition. Either one is way too much for such a standard feature.

What the hell, Microsoft? All I want is a checksumming file system. Either provide it, or don’t. Don’t give me a checksumming filesystem that can’t be Continue reading

Why TLS 1.3 isn’t in browsers yet

Upgrading a security protocol in an ecosystem as complex as the Internet is difficult. You need to update clients and servers and make sure everything in between continues to work correctly. The Internet is in the middle of such an upgrade right now. Transport Layer Security (TLS), the protocol that keeps web browsing confidential (and many people persist in calling SSL), is getting its first major overhaul with the introduction of TLS 1.3. Last year, Cloudflare was the first major provider to support TLS 1.3 by default on the server side. We expected the client side would follow suit and be enabled in all major browsers soon thereafter. It has been over a year since Cloudflare’s TLS 1.3 launch and still, none of the major browsers have enabled TLS 1.3 by default.

The reductive answer to why TLS 1.3 hasn’t been deployed yet is middleboxes: network appliances designed to monitor and sometimes intercept HTTPS traffic inside corporate environments and mobile networks. Some of these middleboxes implemented TLS 1.2 incorrectly and now that’s blocking browsers from releasing TLS 1.3. However, simply blaming network appliance vendors would be disingenuous. The deeper truth of the Continue reading

Concise (Post-Christmas) Cryptography Challenges

It's the day after Christmas; or, depending on your geography, Boxing Day. With the festivities over, you may still find yourself stuck at home and somewhat bored.

Either way; here are three relatively short cryptography challenges, you can use to keep you momentarily occupied. Other than the hints (and some internet searching), you shouldn't require a particularly deep cryptography knowledge to start diving into these challenges. For hints and spoilers, scroll down below the challenges!

Challenges

Password Hashing

The first one is simple enough to explain; here are 5 hashes (from user passwords), crack them:

$2y$10$TYau45etgP4173/zx1usm.uO34TXAld/8e0/jKC5b0jHCqs/MZGBi
$2y$10$qQVWugep3jGmh4ZHuHqw8exczy4t8BZ/Jy6H4vnbRiXw.BGwQUrHu

HTTP Strict Transport Security

A website works by redirecting its www. subdomain to a regional subdomain (i.e. uk.), the site uses HSTS to prevent SSLStrip attacks. You can see cURL requests of the headers from the redirects below, how would you practically go about stripping HTTPS in this example?

$ curl -i http://www.example.com
HTTP/1.1 302 Moved Temporarily
Server: nginx
Date: Tue, 26 Dec 2017 12:26:51 GMT
Content-Type: text/html
Transfer-Encoding: chunked
Connection: keep-alive
location: https://uk.example.com/

$ curl -i http://uk.example.com
HTTP/1.1 200 OK
Server: nginx

Top 5 blogs of 2017: Exciting new things for Docker with Windows Server 1709

We’ve rounded up the most-read Docker blogs of 2017. Topping our list at number two is, Exciting new things for Docker with Windows Server 1709.

What a difference a year makes… last September, Microsoft and Docker launched Docker Enterprise Edition (EE), a Containers-as-a-Service platform for IT that manages and secures diverse applications across disparate infrastructures, for Windows Server 2016. Since then we’ve continued to work together and Windows Server 1709 contains several enhancements for Docker customers.

Docker Enterprise Edition Preview

To experiment with the new Docker and Windows features, a preview build of Docker is required. Here’s how to install it on Windows Server 1709 (this will also work on Insider builds):

Install-Module DockerProvider
Install-Package Docker -ProviderName DockerProvider -RequiredVersion preview

To run Docker Windows containers in production on any Windows Server version, please stick to Docker EE 17.06.

Docker Linux Containers on Windows

A key focus of Windows Server version 1709 is support for Linux containers on Windows. We’ve already blogged about how we’re supporting Linux containers on Windows with the LinuxKit project.

To try Linux Containers on Windows Server 1709, install the preview Docker package and enable the feature. The preview Docker EE package includes a full LinuxKit Continue reading

The History of Stock Quotes

In honor of all the fervor around Bitcoin, we thought it would be fun to revisit the role finance has had in the history of technology even before the Internet came around. This was adapted from a post which originally appeared on the Eager blog.

On 10th of April 1814, almost one hundred thousand troops fought the battle of Toulouse in Southern France. The war had ended on April 6th. Messengers delivering news of Napoleon Is abdication and the end of the war wouldn’t reach Toulouse until April 12th.

The issue was not the lack of a rapid communication system in France, it just hadn’t expanded far enough yet. France had an elaborate semaphore system. Arranged all around the French countryside were buildings with mechanical flags which could be rotated to transmit specific characters to the next station in line. When the following station showed the same flag positions as this one, you knew the letter was acknowledged, and you could show the next character. This system allowed roughly one character to be transmitted per minute, with the start of a message moving down the line at almost 900 miles per hour. It wouldn’t expand to Toulouse until 1834 however, Continue reading

Simple Cyber Security Tips (for your Parents)

Today, December 25th, Cloudflare offices around the world are taking a break. From San Francisco to London and Singapore; engineers have retreated home for the holidays (albeit with those engineers on-call closely monitoring their mobile phones).

Software engineering pro-tip:

Do not, I repeat, do not deploy this week. That is how you end up debugging a critical issue from your parent's wifi in your old bedroom while your spouse hates you for abandoning them with your racist uncle.

— Chris Albon (@chrisalbon) December 20, 2017

Whilst our Support and SRE teams operated on a schedule to ensure fingers were on keyboards; on Saturday, I headed out of the London bound for the Warwickshire countryside. Away from the barracks of the London tech scene, it didn't take long for the following conversation to happen:

• Family member: "So what do you do nowadays?"
• Me: "I work in Cyber Security."
• Family member: "There seems to be a new cyber attack every day on the news! What can I possibly do to keep myself safe?"

If you work in the tech industry, you may find a family member asking you for advice on cybersecurity. This blog post will hopefully save you Continue reading
