An international law firm and longtime customer of WinMagic has leveraged our flagship encryption and key management platform – SecureDoc Enterprise Server – to protect thousands of endpoint devices against loss or theft. In this era of digital transformation though, protecting endpoints is only one of many projects within their security and risk management portfolio. Now as the organization aim to leverage the undeniable benefits of cloud computing, IT had a new mandate to move their existing server infrastructure to Microsoft Azure. Security and compliance risks could no longer prevent cloud migration, despite concerns about undisclosed access to sensitive workloads; particularly those related to client cases, which could be subject to subpoena or government access.
In my recent blog “Pre-Boot Authentication. Wisdom in Security” I wrote in conclusion:
Bottom Line: ‘No PBA’ is not a wise choice for enterprises
Microsoft’s reasoning that you don’t need PBA because the known memory attacks are difficult to pull off on most modern hardware is simply wrong because the threat is much more than just those attacks.”
The Cold Book Attack was resurrected last week by some researchers at f-secure https://press.f-secure.com/2018/09/13/firmware-weakness-in-modern-laptops-exposes-encryption-keys/ . I would like to provide some context for both the exploit and the mitigations because the cold boot attack is just the tip of the iceberg. But first, if you don’t want to know the details, there are steps that organizations can take to protect against Cold Boot attacks on PC’s and Macs when using SecureDoc including:
It has been awhile since I last wrote about computer forensics and encryption so it is time for an update.
First, what is Computer Forensics? According to Wikipedia, Computer forensics is, “a branch of digital forensic science pertaining to legal evidence found in computers and digital storage media. The goal of computer forensics is to examine digital media in a forensically sound manner with the aim of identifying, preserving, recovering, analyzing and presenting facts and opinions about the information.” In short it is like data recovery, but with additional guidelines and practices designed to create a legal “audit trail” that could be used in court if need be.
As my colleague Garry McCracken ably reported earlier in this blog (Is Microsoft claiming Pre-Boot Authentication for FDE is not necessary?), Microsoft, in its wisdom, has declared that pre-boot authentication (PBA) for full-disk encryption (FDE) is not strictly necessary – except in cases where certain other security measures cannot be implemented.
I once worked for a company who didn’t believe in Technical Support employees working from home, despite having all the technology in place to allow that to happen. Their reasoning? Technical Support employees couldn’t be effective if they were not in the office. I’ve always thought that thinking was flawed, and my experiences with the work from home policy that WinMagic has in place reinforces that belief.
I once again had the pleasure and privilege to attend the RSA Security conference in San Francisco, CA. rsaconference.com/events/us18. The conference keynotes, sessions and sidebar conversations were a good opportunity to see what the hot topics in security are. I attended a broad selection of sessions. Here are five diverse observations that I came away with:
Back in November of last year, I was part of a conference call with a European customer who needed some high level reassurance from us. As part of that request, they mentioned that our customer portal could not help them properly manage support tickets. Thus, I hijacked the call and started a GoToMeeting session from my desktop. I gave them the opportunity to walk me through exactly what they found problematic about our customer portal. For the next 20 minutes they did a masterful job of highlighting what areas of the customer portal simply weren’t working for them. And If put myself in their shoes, I could see that they were not only right, but it was likely that other customers felt this way and had never said anything to us.
With this knowledge, I did something radical, which was to hold many meetings over the next two months where I would bring a proof of concept to the table, and have the customer critique it. This helped us to get to where we are today. Which is, to announce the release of Phase One of our enhanced customer portal.
Recently, I was on the phone with a customer who asked me this question: “How can we better help you to help us?” That’s a question that I was not used to getting. But it made me think about what customers could do to get better tech support. I ended up taking a day or two for me to really think about it, but I came up with the following which I decided to share with you:
Managing BitLocker in Windows 10
So you’ve heard – Windows 10 has hit the PC world by storm, with widespread adoption in the private and public sector catching up to the consumer side. According to Gartner, the adoption of Windows 10 is faster than previous OS and the traditional refresh cycles are shortening. What’s driving the movement? Well, it’s a combination of events really, all based on one common need – Security.
