Im Internet Explorer 10 verspricht Microsoft einen bessen Schutz gegenüber Malware. Dies soll über eine neue Technik mit dem Namen "High Entropy Address Space Layout Randomization (HEASLR)" erreicht werden. High Entropy Address Space Layout Randomization (HEASLR) ist dabei eine Erweiterung des ASLR Mechanismus aus Vista/7. Durch den 64Bit Adressraum können die DLLs an viel mehr unterschiedlichen Adressen geladen werden um so Attacken zu verringern:
ZITAT
High Entropy Address Space Layout Randomization (HEASLR) takes advantage of the increase in 64bit address space and assigns more bits to entropy. This has the effect of drastically increasing the number of potential addresses that may be assigned to a 64bit process. All 64bit processes can opt-in to the increased entropy made available by HEASLR. Processes can opt-in either at link time (/HIGHENTROPYVA) or at load time via a new Image File Execution Option.
By default, the Metro style browser runs in 64bit mode on 64bit computers, providing a much larger address space and thus more random memory layout.
