68 @aGlance/IT Server Interface
8.3 Security for the @aGlance/IT Server
The two aspects to security for the @aGlance/IT API for Micro-DCI are:
• client access to the @aGlance/IT server for Micro-DCI, and
• access to the Micro-DCI Global database
8.3.1 Security for Access to the @aGlance/IT Server for Micro-DCI
Client proxy definition is used to specify which clients are permitted to access the server applications on
the local node. A client proxy account is a mapping from a remote host name and user ID to a local ID.
Client proxies are configured on the node in which the @aGlance/IT Server for Micro-DCI is installed.
Client proxy definition is performed using the @aGlance/IT Administration Tool. (Access to the
@aGlance/IT Administration Tool is described in
Section 8.2.1.1 .) From the @aGlance/IT Administration
Tool, select the Proxies option.
From the user interface of the Proxies option, the following three types of client proxy accounts can be con-
figured:
• One user on one host (a separate proxy account for a user on a remote node)
• All users on one host (a single proxy account for ALL users on a remote node)
• All users on all hosts (a single proxy account for ALL users on ALL remote nodes)
In all cases, the default proxy is called AAG.
The simplest procedure is to set up a single account for all users on all remote nodes. To use the default
proxy (AAG), configure a Micro-DCI user named
AAG, using the user login configuration as described in
Section 2 of the Micro-PWC Configuration Guide. The desired access level and area permissions should
be configured for the user named
AAG.
Client proxy definition is a function of the @aGlance/IT Administration Tool provided by Axeda Systems
Inc.; it does not contain provisions for passwords on client proxy accounts. Security is based on the
@aGlance/IT server for Micro-DCI matching the remote node and user names with the local proxy config-
uration at runtime.
See the @aGlance/IT on-line help subsystem for information on client proxies and how to configure them.
8.3.2 Security for Micro-DCI Database Access
Database access security for the @aGlance/IT Server for Micro-DCI is based on the access level and area
permissions configured on the remote node for the user running the @aGlance/IT client software. The
access level and area permissions correspond to the local user name specified in the @aGlance/IT proxy
account. Each session can be associated with a different proxy account.
8.4 Supported @aGlance/IT Client Applications
"Add-Ins" are software packages which provide client applications with an @aGlance/IT client interface,
thus providing the application with the ability to interface with systems which include an @aGlance/IT
server. Clients and servers can have totally different hardware architectures; the differences in underlying
network protocols are resolved by the @aGlance/IT software.
For information on supported Add-Ins, see the Micro-PWC Configuration Guide.
