Overhead and Performance Impact when Using Full Drive Encryption with HP ProtectTools and SSD

E-mail Print PDF

After some weeks of waiting, I received my new HP EliteBook 8440p with the following parameters:

Processor type
Intel® Core™ i7-620M Processor (2.66 GHz, 4 MB L3 cache)
Operating system installed
Windows® 7 Professional 32
Mobile Intel® QM57 Express
Standard memory
4 GB 1333 MHz DDR3 SDRAM
Memory slots
2 SODIMM slots supporting dual channel memory
Internal drives
160 GB 2.5-inch Solid State Drive


As a security professional, I prefer having all my drives and information securely encrypted on my laptop so that in case of theft or loss, all my sensitive data stays safe. The first tool, which comes to one's mind is BitLocker - the Microsoft encryption tool, which was made available in Windows Vista for the first time. Unfortunately my Windows® 7 Professional supplied together with my laptop does not support BitLocker as it is available in the Ultimate and Enterprise versions of Windows 7 only. After an inquiry by HP, if it is possible to get an update from Windows 7 Professional to Windows 7 Ultimate, it became clear that I should basically buy a brand new Windows 7 Ultimate license. So I started looking for alternatives.



Firefox 3.x and the Problem with Self-Signed/Untrusted Certificates

Nowadays most recent browsers are becoming pretty aggressive against certificates not issued by trusted authorities which are not configured in the trust certificate store of the browser itself.

As a web application tester, I often use different tools for modifying parameters and trying to go around checks and validations performed on the client side. Such tools are Paros and WebScarab - these are two HTTP proxies which tunnel the client's requests and allow modification of the data before it is sent to the server.
