Reactive defense mechanisms, such as intrusion detection systems, have made significant
efforts to secure a system or network for the last several decades. However, the nature of …

Moving target defense (MTD) has emerged as one of the game-changing themes to alter the
asymmetric situation between attacks and defenses in cyber-security. Numerous related …

Context: Diversification and obfuscation are promising techniques for securing software and
protecting computers from harmful malware. The goal of these techniques is not removing …

The concept of destructive code reads is a new defensive strategy that prevents code reuse
attacks by coupling fine-grained address space layout randomization with a mitigation for …

Diversity-based security approaches have been studied for several decades since the
1970s. The concept of diversity-by-design emerged in the 1980s. Since then, diversity …

JIT spraying allows an attacker to subvert a Just-In-Time compiler, introducing instruction
sequences useful to the attacker into executable regions of the victim program's address …

Moving Target Defense (MTD) has been proposed as a game-changing theme to increase
the work effort to attack as well as the security of target system. There has been proposed a …

Language Virtual Machines (VMs) are the run-time environment of popular high level
managed languages. They offer portability and memory handling for the developer and are …

Moving target defenses raise the cost of an attack to make it more difficult or infeasible.
Strategies to do so include implementing diversity, movement, and obfuscation at the …
