Fixing the mixed content problem with Automatic HTTPS Rewrites

CloudFlare aims to put an end to the unencrypted Internet. But the web has a chicken and egg problem moving to HTTPS.

Long ago it was difficult, expensive, and slow to set up an HTTPS capable web site. Then along came services like CloudFlare’s Universal SSL that made switching from http:// to https:// as easy as clicking a button. With one click a site was served over HTTPS with a freshly minted, free SSL certificate.

Boom.

Suddenly, the website is available over HTTPS, and, even better, the website gets faster because it can take advantage of the latest web protocol HTTP/2.

Unfortunately, the story doesn’t end there. Many otherwise secure sites suffer from the problem of mixed content. And mixed content means the green padlock icon will not be displayed for an https:// site because, in fact, it’s not truly secure.

Here’s the problem: if an https:// website includes any content from a site (even its own) served over http:// the green padlock can’t be displayed. That’s because resources like images, JavaScript, audio, video etc. included over http:// open up a security hole into the secure web site. A backdoor to trouble.

Web browsers have known this was a problem Continue reading

IDG Contributor Network: AT&T’s AirGig shows wireless internet over power lines is possible

High-speed wireless internet could soon be delivered over power lines, according to a major mobile network operator that announced positive test results of a proposed system.AT&T says its project, called AirGig, will deliver multiple gigabit-speed wireless internet by creating broadband signals that will emanate from the power lines crossing the country and beyond.The company says it won’t actually connect its equipment directly to the powerline cables but will simply use the wires as way to send modulated radio signals to individuals’ homes, smartphones, tablets and so on. The equipment sits atop the utility poles and uses the existing wires for transmitting and receiving.To read this article in full or to leave a comment, please click here

Google’s Allo is an early personal assistant, not a late-to-market messaging app

Allo is a child that Google just sent to school to become your personal assistant. The first release looks like a messenger app because it is a common user interface (UI) that almost all smartphone users know, and it is conversational. Like a child learns to speak through conversation with adults, Allo will learn to be a personal assistant through quadrillions of messaging conversations if it succeeds as the next big platform.Google Now and Apple’s Siri are rudimentary compared to the personal assistant that Google Allo could become. Google Now’s and Siri’s voice to text is pretty accurate, but the user is limited to a fixed set of commands, navigate, play music, search, etc.To read this article in full or to leave a comment, please click here

Plan now for the EU’s privacy regulation revolution, says HPE exec

The cost of complying with the European Union's General Data Protection Regulation might seem like something best deferred until it enters force in 2018 -- but working on compliance just might boost profit, not reduce it.The GDPR, the EU's latest rewrite of its data privacy laws, doesn't enter effect until May 25, 2018, but already IT companies are talking up their software and services for complying with the new rules.It's not just an issue for EU enterprises: Any company processing the personal information of EU citizens is affected.To read this article in full or to leave a comment, please click here

IDG Contributor Network: MacOS Sierra: The day nothing happened

I was notified that a software update was available for a few of my systems. An update to macOS Sierra was available for my main production system, a MacBook Pro, and my travel system, a MacBook Air.

Lockdown! Harden Windows 10 for maximum security

You may have heard that Microsoft has made Windows 10 more secure than any of its predecessors, packing it with security goodies. What you might not know is that some of these vaunted security features aren’t available out of the box or they require additional hardware -- you may not be getting the level of security you bargained for.Features such as Credential Guard are available for only certain editions of Windows 10, while the advanced biometrics promised by Windows Hello require a hefty investment in third-party hardware. Windows 10 may be the most secure Windows operating system to date, but the security-savvy organization -- and individual user -- needs to keep the following hardware and Windows 10 edition requirements in mind in order to unlock the necessary features to achieve optimum security.To read this article in full or to leave a comment, please click here

Were Apple’s ‘leaked’ iPhone 7 tweets really a mistake?

Apple hasn't embraced social media the way its tech rivals have, but the company appears to have warmed to the medium. Today Apple uses its @AppleSupport account on Twitter as a customer service and outreach tool, and the company also maintains Twitter accounts for some of its most popular services, including Apple Music, the App Store, iTunes and Beats1. Apple also finally started to use its main @Apple Twitter account in the days leading up to the iPhone 7 launch earlier this month. But things got off to a bit of a rocky start. During the company's presentation, the company published and then immediately deleted at least three tweets to the @Apple account that revealed details and key features of the iPhone 7 — before it was officially announced.To read this article in full or to leave a comment, please click here

A Cisco-Salesforce deal means collaboration will come to you

The hardest thing about adopting an enterprise collaboration platform can be adoption itself – getting employees to actually start up the new software and then turn to it whenever they need to communicate.Putting the software inside something that workers already use is one way to drive adoption and also make the communication tools more valuable. Cisco Systems knows this, and on Thursday the company announced a strategic alliance with Salesforce, its second big partnership in that direction after its headline-grabbing Apple iOS integration.To read this article in full or to leave a comment, please click here

Why Would I Use BGP and not OSPF between Servers and the Network?

While we were preparing for the Cumulus Networks’ Routing on Hosts webinar Dinesh Dutt sent me a message along these lines:

You categorically reject the use of OSPF, but we have a couple of customers using it quite happily. I'm sure you have good reasons and the reasons you list [in the presentation] are ones I agree with. OTOH, why not use totally stubby areas with the hosts being in such an area?

Cisco: Yes, cosmic radiation could have caused router bug

Yesterday we reported on the reaction to a Cisco bug report that speculated “partial data traffic loss” on the company’s ASR 9000 Series routers was possibly triggered by “cosmic radiation causing SEU soft errors.”Reaction to that contention on a Reddit forum ranged from the obvious -- acknowledgment that cosmic radiation is an issue -- to sharp-tongued skepticism and tales of the cosmic radiation villain being used as a tongue-in-cheek place-holder meaning “we really don’t know what caused the problem yet.”To read this article in full or to leave a comment, please click here
