SIMPLE IS BETTER: BitVisor - A Thin Hypervisor Built for Enforcing I/O Device Security - Storage (USB/DISK) Encryption or File Access Monitoring
http://www.hypervsir.blogspot.com/2014/11/paper-read-bitvisor-thin-hypervisor-for.html
Wednesday, November 05, 2014. BitVisor - A Thin Hypervisor Built for Enforcing I/O Device Security - Storage (USB/DISK) Encryption or File Access Monitoring. This post is wrote to share an idea of the paper ( BitVisor: A Thin Hypervisor for Enforcing I/O Device Security. That I read recently. It. Innovates a hypervisor-based solution for enforcing storage/disk encryption of ATA devices. As shown in picture below (from wikipedia. Although the processor has no chance to intercept the data transferred betwe...
SIMPLE IS BETTER: Control-flow processor exceptions (single-stepping on branches) on control-flow branch instructions (jmp/call/ret)
http://www.hypervsir.blogspot.com/2015/01/processor-exception-after-control.html
Monday, January 26, 2015. Control-flow processor exceptions (single-stepping on branches) on control-flow branch instructions (jmp/call/ret). Single-stepping on branches" is processor hardware feature of x86/Intel architecture. When it is enabled, the processor generates a single-step debug exception only after instructions that cause a branch. Allows a debugger to single-step on control transfers caused by branches. In x86/Intel processor architecture, there is a bit (Trap Flag, TF) in EFLAGS register a...
SIMPLE IS BETTER: New security feature - Control Flow Guard (CFG) - available in Visual Studio 2015 Preview
http://www.hypervsir.blogspot.com/2014/12/new-secruity-feature-control-flow-guard.html
Thursday, December 11, 2014. New security feature - Control Flow Guard (CFG) - available in Visual Studio 2015 Preview. The Preview for Visual Studio 2015 includes a new, work-in-progress feature, called Control Flow Guard (CFG). If that check fails at runtime, the Operating System closes the program". I will evaluate this, e.g. performance impact and effectiveness against JOP/ROP attacks,. When I'm free, and update this post then :-). MJ0011, "Windows 10 Control Flow Guard Internals".
SIMPLE IS BETTER: "What, How, and Why" on Interrupt Window (or NMI Window) Exiting in Virtualization Technology

Monday, April 06, 2015. What, How, and Why" on Interrupt Window (or NMI Window) Exiting in Virtualization Technology. More recently, one of my colleagues asked me why. There is a feature called " Interrupt Window exiting. In virtualization technology, and how. It can be used by VMM? This blog is going to briefly describe its "what, how and why" . WHAT, and HOW. At which RFLAGS.IF = 1 (external interrupt is unmaksed) and,. So, in order to deliver this interrupt, the VMM will need to poll and check the int...
SIMPLE IS BETTER: Page Table Structure Corruption Attacks - How to Mitigate it?
http://www.hypervsir.blogspot.com/2014/11/page-structure-table-corruption-attacks.html
Tuesday, November 18, 2014. Page Table Structure Corruption Attacks - How to Mitigate it? On x86 and many other processor architectures (with MMU), page tables are critical data structures for address translations. And many hardware-based page level protection technologies in my previous post. Like SMEP, XD/DEP, highly depend on correct page table settings. so what if page tables are controlled by an attacker? Recently, this post ( Windows 8 Kernel Memory Protections Bypass. Similarly, DEP (Data Executio...
