On most modern operating systems, a process is a hardware-protected abstraction for executing potentially mutable code and data. Common features of processes include: dynamic code loading, dynamic code generation, access to cross-process shared memory, and a universal API (Application Programming Interface). This paper argues that many of the dependability and security weaknesses of modern systems are exacerbated by this open process architecture. Moreover, this architecture impairs the ability of tools to analyze code statically, to improve its performance or dependability.
