An international law firm and longtime customer of WinMagic has leveraged our flagship encryption and key management platform â SecureDoc Enterprise Server â 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 â(308) 636-3261âÂ I wrote in conclusion:
Bottom Line: âNo PBAâ is not a wise choice for enterprises
Microsoftâs reasoning that you donât 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 Â attacks.â
The Cold Book Attack was resurrected last week by some researchers at f-secure idiolatry .Â 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. Â Â But first, if you donât want to know the details, there are steps that organizations can take to protect against Cold Boot attacks on PCâs and Macs when using SecureDoc including:
In the past, I have tried to make the case for encrypting physical servers on premise.Â The argument for not needing to encrypt them is that these servers usually run for weeks, months or even years without being brought down, and that they are physically protected within a well-fortified data center.Â The protection that Full Drive Encryption (FDE) brings only really applies to data at rest, and it seldom is at rest on these servers.Â I would counter that all drives eventually leave the data center for repair or disposal, and having them encrypted protects you from having your old drives show up on eBay, with your customer data still on them.Â Encrypting the drive means it can be quickly and easily crypto-erased if it is still operational, and if not, the data is still not accessible without the encryption key.

Innovation, Meet Security
Digital banking has transformed the way we connect and transact with one another. From mobile banking apps to contactless payments, a focus on consumer experience has driven new technologies like never before seen. The consistent, common factor â convenience.
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?Â Â According to Wikipedia, Computer forensics is, âa 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.âÂ Â In short it is like data recovery, but with additional guidelines and practices designed to create a legal âaudit trailâ 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 â except in cases where certain other security measures cannot be implemented.
I once worked for a company who didnât 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 couldnât be effective if they were not in the office. Iâve always thought that thinking was flawed, and my experiences with the work from home policy that WinMagic has in place reinforces that belief.
On one hand, Microsoft says that BitLocker with pre-boot authentication (TPM + PIN) is the recommended best practice ((732) 364-1318). Â On the other, Microsoft admits that BitLocker with their pre-boot authentication âinconveniences users and increases IT management costs.â A mixed message for any IT pro responsible for keeping devices compliant and secure.
Read on to discover the compliance shortfalls of BitLocker and how to address them.
