Web Browser Setup
• Set up the browser to accept cookies.
• Validate Java scripts.
• When using proxy servers, set up the browser so that both authentication and business servers are
connected through proxy servers.
• Set up the browser to use SSL2.0 and SSL3.0.
Application of Security Patch
The client system may be attacked and cookies may be stolen when a problem occurs in the Web
browser being used. If such a trouble is detected, the developer of the Web browser releases a security
patch. The system administrator must instruct all users of the operating system to always apply the
latest security patches to their browsers.
About Proxy Servers
When a load balancer, such as Interstage Traffic Director, is used for load balancing, the proxy server
through which a client is connected may be varied per access according to load balancer settings.
Since the authentication and business servers recognize the proxy server address as the client address,
if the proxy server is varied, the client address will be different between the access to the authentication
server and the access to the business server.
If it occurs, the Single Sign-on operation cannot be validated. To avoid this problem, ensure the load
balancer is set up so that access to the same client always uses the same proxy server.
For example, when "Balancing for each node" is specified for Interstage Traffic Director, every request
from the same client is connected to the same server.
