Executive Summary

Securing access to files is an important and growing concern in corporate environments. Employees are increasingly accessing files from untrusted devices, including personal home computers and mobile devices, such as smart phones, that are not under the control of the corporation, and may be infected with viruses, worms, and other malware. In such cases, it is crucial to protect the confidentiality and integrity of corporate data from malicious accesses. Existing tools available to network administrators are either too permissive or too restrictive in allowing file access from untrusted devices.
