This suggests a form of server to server communication and load-balancing which is currently not a part of the HTTP specification. The data may require to be replicated across several storage systems and duplicate servers on other computer systems may be necessary as a failsafe measure to ensure constant access. Security Security of the server depends upon the type of implementation of the kiosk, whether standalone or remote server based. However, certain common elements exist in both, such as physical access to the server's computer system. Access to the console of the server should only be allowed to secure personnel to ensure the safety of the information.
Network security is another issue.
Access to the computer network that the servers are located on should be secure to reduce the chance of computer cracking or vandalism of the information. Since most servers run on common operating systems such as UNIX, VMS, etc., operating system security is also a crucial element in the safety of the information. Data managers should decide upon a protocol for operator access, updating and maintainence of the information since it can affect the lives of many others. Another form of access is dependent upon the content of the documents. A public system will not often contain restricted documents but data managers may wish to restrict certain areas of their Webspace dependent upon their own criteria.
