As outlined in our previous article, Windows 10 Security, The Good, The Bad, and The Ugly, there are several exciting new security features in Windows 10 Enterprise, such as Device Guard and Credentials Guard, that leverage features of more recent hardware. In order to take full advantage of all that Windows 10 Enterprise has to offer, you will probably need to convert a lot of existing boot drives from BIOS to UEFI, and when you do that, you will also want to enable the Secure Boot feature of your workstation hardware. Sound opaque and confusing? This article will explain what it means and talk about some strategies for making the conversion in your enterprise.
As we noted in our Windows 10 Security overview, one of the exciting new features of Windows 10 Enterprise is Device Guard, an operating system feature for ensuring that only trusted code runs on your systems. At its best, Device Guard uses a signature based model for trusting executables and libraries. However, in an ecosystem with as much legacy as exists in Windows, Device Guard also gives the enterprise the means to handle legacy applications as well.
Develop a transition strategy for a successful Windows 10 upgrade, and make this migration your best.
The following article was written by Eden's own Andy Sherman. It originally appeared on his blog, "My Security Musings." I received an interesting phishing email today. It was from a business acquaintance and contained a link gussied up to look like an online document. The content and format of the email screamed "suspect me" so I did. A URL lengthener confirmed that the tinyurl.com link went someplace having no connection to me or the acquaintance.
What is Ransomware? It seems that hardly a day goes by that we don’t read about a new strain of ransomware or a new victim of a ransomware attack. Ransomware is malware that encrypts the user’s or organization’s files and demands payment for the decryption key. The ransomware business model is often one that provides friendly customer service and really does deliver the key in exchange for the requested amount of Bitcoin. However, there is no guarantee that they will, and they don’t always, so it’s not a long term strategy for protecting your enterprise to depend upon the good will of criminals.
There’s a lot of buzz around Windows 10 security. For example, Infoworld dubs Windows 10 as “the most secure Windows ever.” Although that sounds like the hype cycle at work, in fact, some of the new security features in Windows 10 are game changers that will help change the balance of power between enterprise customers and the perpetrators of Advanced Persistent Threats (APT). There’s also at least one monstrously bad idea baked into Windows 10, and the usual collection of features where we think the default behavior is too open and should be modified.

Juniper’s NetScreen series of firewall and VPN devices have not one but two backdoor vulnerabilities, Juniper disclosed. One of these vulnerabilities is an authentication bypass for telnet or SSH logins to the firewall. The other is an encryption weakness that allows for eavesdropping on VPN traffic. Needless to say there has been a lot of discussion in the technicalpress, especially in light of the current political climate around encryption and back doors. Patches are available to cover both vulnerabilities. Juniper notes that no other Juniper products, in particular JunOS based products, are affected by these vulnerabilities.
Digital Guardian asked a bunch of security experts (including me) for their predictions on where the Data Loss Prevention (DLP) market was going in 2016 and beyond.
We recently posted about an uptick in wire transfer fraud through bogus email. Since then we and two of our clients have been the subject of such attacks. All were emails purporting to be from executive leadership (CEOs or Partners) to the people in their organization responsible for finance.
