Cyclone Programming Language: Safe C-like Control and Memory Management

Cyclone is a programming language based on C that is safe, meaning that it rules out programs that have buffer overflows, dangling pointers, format string attacks, and so on. High-level, type-safe languages, such as Java, Scheme, or ML also provide safety, but they don't give the same control over data representations and memory management that C does (witness the fact that the run-time systems for these languages are usually written in C.). . .

Enhancing Application Security via Privman Library and Privilege Separation

Douglas Kilpatrick sent in a note about a new open source project going on at Network Associates. "Privman is a library that makes it easy for programs to use privilege separation, a technique that prevents the leak or misuse of privilege from applications that must run with some elevated permissions. Applications that use the Privman library split into two halves, the half that performs valid privileged operations, and the half that contains the application's logic. The Privman library simplifies the otherwise complex task of separating the application, protecting the system from compromise if an error in the application logic is found.. . .
