A DSL for cross-domain security

Abstract

Guardol is a domain-specific language focused on the creation of high-assurance network guards and the specification of guard properties. The Guardol system generates Ada code from Guardol programs and also provides specification and automated verification support. Guard programs and specifications are translated to higher order logic, then deductively transformed to a form suitable for a SMT-style decision procedure for recursive functions over tree-structured data. The result is that difficult properties of Guardol programs can be proved fully automatically.
