An Application for Normal and Critical Operations in a Tactical MLS System
Abstract
The ability for first responders to access sensitive and critical information during an emergency can help save lives and reduce damage. There may be information normally unavailable to first responders that could help during a crisis. The Transient Tactical Access to Sensitive Information (T-TASI) system is intended to employ an emergency access control policy and be a scalable security solution for transient trust. Built on a least privilege separation kernel (LPSK), the T-TASI system allows a coordinating authority to provide temporary, controlled access to sensitive information to authorized first responders, during emergencies. The current T-TASI system prototype, however, lacks applications demonstrating this capability. This work has developed a T-TASI system application. Through analysis, three necessary software subsystems were identified: a memory management system, a file storage system and an application-level library providing interfaces compliant with the standard C library. We describe the design, implementation, and testing of the application and the three supporting components, all of which will facilitate future application development for the T-TASI system.
