Abstract

Coding standards and guidance for secure programming call for sensitive data to be “sanitized” before being de-allocated. This paper considers what this really means in technical terms, why it is actually rather difficult to achieve, and how such a requirement can be realistically implemented and verified, concentrating on the facilities offered by Ada and SPARK. The paper closes with a proposed policy and coding standard that can be applied and adapted to other projects.
