Based on my earlier posts, I've recently written a whitepaper for Microsoft France on how to build a machine that is capable of dual booting either Linux or Windows Vista when the latter is protected by BitLocker leveraging a TPM chip. If you understand...

( This is part 5 of our series of posts on service hardening .) Last but not least a service can be (and should be) configured to have network restrictions with what is called the "Windows Service Hardening" rules in the Windows SDK (we'll call those...

( This is part 4 of our series of posts on service hardening. ) A service can be configured to be write-restricted, in addition to having a per-service SID. To do so, you specify a SID type of "Restricted" when configuring your service (see our previous...

(This is part 3 of our series of posts on service hardening.) Under Windows Vista/Longhorn Server, your service can now have its own SID (Security Identifier), which you can then use in ACLs to protect your service resources. You configure your service...

This is part 2 of our series of posts on service hardening. "Need to have" and least privilege principle Executing with least privilege is a good practice of computer security. As with the "need to know" principle for information access, there...

You may have heard that built-in services in Windows Vista were specifically hardened by Microsoft engineers during its development process. You might be wondering what that really means, how it works and, if you are a developer, how to harden your own...

Yesterday, the first Microsoft Techdays ended in Paris after three days and more than 200 presentations. Thank you to all of you who honored us by their attendance! (I don’t have the final figures yet but you were about 9,000 people on the two first days...

People: the weakest link or a chance for security? Have you ever heard security experts? They all point out that the human factor is the weakest link in the security chain. They often make fun of people being victims of social engineering for instance...

Updated 2008-05-12 : added a step to turn the TPM on before enabling BitLocker. By the way, someone made me notice this post is now referenced by the official BitLocker FAQ on Microsoft's website. Many people have wondered if it would be possible...

The Web is full of explanations on how to dual boot Windows and Linux using a Linux boot manager like GRUB or LILO. If you want to dual boot Windows Vista and Linux using Windows Vista’s Boot Manager, please read on. I will assume that you already have...

Hello everyone! As you can see, I decided to start blogging on security, maybe sometimes on interoperability. To be honest, if the blogosphere was the solar system, I could be found closer to Neptune than Mercury. However, I’ve been spending more than...
