Toshiba Magnia 3200 - Manual (Page 22)

1.3.2 Notes on System Configurations
Minimum configuration
In an environment with only one server, all modules are installed in one server. In this
environment, the fault report function does not work if a server fails (crashes, locks up,
etc.)
Medium-scale configuration
In an environment where several servers are installed, a Management Proxy is installed in
at least one server and only the Agent is installed in the other server units. The
Management Proxy runs 24 hours a day to monitor each Agent (including the
Management Proxy itself).
Large-scale configuration
In an environment where some dozens of servers are installed, a Management Proxy is
installed in two servers and only the Agent is installed in the other server units. Each
Management Proxy runs 24 hours a day to monitor the Agents (including the
Management Proxy itself).
About HEW version
When an Agent function of HEW Ver.3.1 is installed, the Management Proxy, where the
agent is to be registered needs to be HEW Ver. 3.1, too.
When a Management Proxy function of HEW Ver.3.1 is installed, a Manager function or an
Agent function that its Management Proxy manages of HEW Ver.3.1 or older version
are supported.
1.3.3 Security
HEW does not have any function for security of data transferred in the network. It is
recommended that the customer take security measures appropriate for the customer’s
environment.
When it is necessary to restrict the use of HEW to specific users, the access to the HEW folder
can be restricted using IIS settings.
Windows NT and Windows 2000 permit Virtual Private Network (VPN) to be used as a network
communication security technology.

(Appendix 5 Virtual Private Network Setting)
Please be careful of the following things about the security of Internet Explorer.
Please start an Internet Explorer, and select [Tools]-[Internet Options]. On [Security] tab, select
the zone that you want to use. On [Security level for this zone], when the button [Default Level]
is not invalid, click this button. Then a level is displayed on [Security level for this zone].
If the level is "High", please change this since the screens of HEW can be not displayed
correctly and the remote console function is not available.
If the level is "Low", when you use a remote console function, "Terminal Service ActiveX
Control" is downloaded without displaying a security-warning dialog. When you want to
display a security-warning dialog, please do not set "low" as a level.
