Providing secure remote access to legacy healthcare applications

摘要

While the widespread adoption of Internet and Intranet technology ahs been one of the exciting developments of recent years, many hospitals are finding that their data and legacy applications do not naturally fit into the new methods of dissemination. Existing applications often rely on isolation or trusted networks for their access control or security, whereas untrusted wide area networks pay little attention to the authenticity, integrity or confidentiality of the data they transport. Many hospitals do not have the resources to develop new 'network- ready' versions of existing centralised applications.
