CPU-Z is a freeware system profiler (system monitor) application for Microsoft Windows (for all versions from Windows XP on) that detects the central processing unit, RAM, motherboard chipset, and other hardware features of a modern personal computer, and presents the information in one window.

But don’t worry in Linux there are many alternative, and in the past I’ve presented 3 command line commands that you can use to get information on your Linux box: lsusb, lspci and lshw and a graphical alternative hardinfo.

Today I’m glad to present you 2 more graphical tools specific to gather information about the CPU: CPU-G and I-Nex

While reading an interesting Blog I discovered a new treasure: TRESOR, in short TRESOR is a secure implementation of AES which is resistant against cold boot attacks and other attacks on main memory.

If like me you wonder what a cold boot attack is, Princeton University can help us :

Contrary to popular assumption, DRAMs used in most modern computers retain their contents for seconds to minutes after power is lost, even at operating temperatures and even if removed from a motherboard. Although DRAMs become less reliable when they are not refreshed, they are not immediately erased, and their contents persist sufficiently for malicious (or forensic) acquisition of usable full-system memory images. This phenomenon limits the ability of an operating system to protect cryptographic key material from an attacker with physical access. We use cold reboots to mount attacks on popular disk encryption systems — BitLocker, FileVault, dm-crypt, and TrueCrypt — using no special devices or materials. We experimentally characterize the extent and predictability of memory remanence and report that remanence times can be increased dramatically with simple techniques.
