BitLocker encryption can be defeated with trivial Windows authentication bypass

Companies relying on Microsoft BitLocker to encrypt the drives of their employees' computers should install the latest Windows patches immediately. A researcher disclosed a trivial Windows authentication bypass, fixed earlier this week, that puts data on BitLocker-encrypted drives at risk.Ian Haken, a researcher with software security testing firm Synopsys, demonstrated the attack Friday at the Black Hat Europe security conference in Amsterdam. The issue affects Windows computers that are part of a domain, a common configuration on enterprise networks.When domain-based authentication is used on Windows, the user's password is checked against a computer that serves as domain controller. However, in situations when, for example, a laptop is taken outside of the network and the domain controller cannot be reached, authentication relies on a local credentials cache on the machine.To read this article in full or to leave a comment, please click here

The secret to a successful identity provider deployment: federate your identity data with a hub

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.

Companies are securing more users who are accessing more applications from more places through more devices than ever before, and all this diversity is stretching the current landscape of identity and access management (IAM) into places it was never designed to reach. At the same time, security has never been more paramount—or difficult to ensure, given today’s outdated and overly complex legacy identity systems. I call this the “n-squared problem,” where we’re trying to make too many hard-coded connections to too many sources, each with its own protocols and requirements.

How to solve today’s top three virtual environment challenges

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.

Virtualization is a mature technology but if you don’t have a virtualization wizard on staff managing the environment can be a challenge. Benefits such as flexibility, scalability and cost savings can quickly give way to security risks, resource waste and infrastructure performance degradation, so it is as important to understand common virtual environment problems and how to solve them.

The issues tend to fall into three main areas: virtual machine (VM) sprawl, capacity planning and change management. Here’s a deeper look at the problems and what you can do to address them:

Stupidity rules: Almost 24 aircraft hit with lasers in one night

Maybe it was a full moon or maybe all the dolts just came out at once, but the Federal Aviation Administration reported that lasers hit nearly two dozen aircraft across the US last night. Sadly the average number of laser strikes on aircraft is about 16 per day. FBI The FAA said three laser strikes were reported in the New York City/Newark, N.J early in the evening, followed by three incidents in Texas, where jets were struck while preparing to land at Dallas Love Field. By late evening, pilots reported laser incidents in cities from Dallas to Los Angeles and San Juan.To read this article in full or to leave a comment, please click here

CISO bets on cloud security services to protect data

In what could be considered an unusual move at a time when most companies choose to keep their cybersecurity tools on-premises, John Graham, CISO for Jabil Circuit, says the manufacturing services company is adopting more cloud security services. Graham says that moving to the cloud lets the company focus on its core business of making high-precision molds, mechanical tools and medical devices. More specifically, it allows his tech staff to focus on threat analytics. Graham expects Jabil’s cloud migration strategy to become the rule rather than the exception.

Intralinks is built from the ground up for secure enterprise file sharing and collaboration

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.  Close to 20 years ago I was working with a company in the process of a blockbuster merger with a competitor. The company set up numerous closed-door "clean rooms" at headquarters where teams from both companies could work through the details of the proposed deal. Scores of people from the target company came to town and lived in hotels for weeks on end.Those of us not on the merger team watched daily as boxes of documents were carted into the clean rooms. We assumed the boxes contained each company's most sensitive business information. The people in those rooms were charged with deciding if the merger was the right thing to do. They hoped the answers would be found in those precious documents. Apparently they were because the merger went through.To read this article in full or to leave a comment, please click here

Continuous integration tools can be the Achilles heel for a company’s IT security

Some of the most popular automated software building and testing tools used by developers have not been designed with security in mind and can open the door for attackers to compromise enterprise networks.These so-called continuous integration (CI) tools allow developers to automatically create software builds when code changes are contributed by developers to a central repository. The creation of these builds, which are used for quality control, is coordinated by a CI master server based on predefined rules and done on CI slave machines.If hackers manage to access a CI master server, they can steal proprietary source code, but also gain the ability to execute commands on all the machines that operate as CI slaves, security researcher and penetration tester Nikhil Mittal said Friday in a presentation at the Black Hat Europe security conference in Amsterdam. "This access could be used for lateral movement to get access to more machines."To read this article in full or to leave a comment, please click here

IDG Contributor Network: Scientists developing high-performing battery for electric cars and drones

Lithium-oxygen batteries will be 10 times as energy-dense as the lithium-ion technology we're using today. It will be significantly lighter than anything we've seen to date.Why the obsession with weight reduction in batteries?Weight is an issue in vehicle battery chemistry because the heavier a vehicle is, the more power you need to propel it. Which means you need more batteries. That results in more weight, and it becomes an ever-decreasing circle.Diminishing returns As things stand now, you can't just keep adding more powerful batteries, because they add weight and size, and actually result in that diminishing return.To read this article in full or to leave a comment, please click here

10 offbeat, odd, and downright weird places you’ll find Linux

The OS that took over the worldImage by David Marsh/FlickrLet's just get this out of the way: this isn't the year of Linux on the desktop. That year will probably never arrive. But Linux has gotten just about everywhere else, and the Linux community can take a bow for making that happen. Android, based on the Linux kernel, is so prevalent on mobile devices that it makes the longstanding desktop quest seem irrelevant. But beyond Android there are a number of places where you can find Linux that are truly odd and intriguing, and by "places" we mean both strange devices and weird geographical locations. This slideshow will show you that it's always the year of Linux pretty much everywhere.To read this article in full or to leave a comment, please click here
