Cyber security at software development time

Secure systems are intrinsically dependent on se cure software. Creating secure software is no simple task and every aspect of the software development lifecycle has to be taken into account. In this article we focus on security in the software implementation phase and present a number of techniques that enable the formal checking of security properties at software development time. We give an overview of some of the automated analysis techniques available today ranging from tree-based pattern matching to model checking. Moreover, we present our source code analysis tool Goanna which integrates those security analysis techniques, and we provide a number of application examples, where Goanna detects real security threats demonstrated in application examples from the National Institute of Standard´s comparative exposition.
