Cloud-Friendly, Virtual, Information Assurance and Cross Domain Services

MetadataShow full item record
Cloud is a powerful paradigm because it applies powerful virtual technology to logically abstract function away from the implementing infrastructure. The same physically distributed infrastructure is dynamically re-configured to create virtual machines optimized to execute the transaction of interest. Traditional transfer guard cross domain solutions are based on physical separation, and are therefore incompatible with this approach. Indeed, their continued mandated use negates the potential efficiencies targeted via cloud. Cloud cross-domain services, based on assured logical separation via hypervisors and other virtual technology can provide the solution. Success requires government-industry partnership to identify an open standard virtual cloud security layer. Success also requires convincing the certification and accreditation community that assurance arguments based on logical separation are valid.
