Fixes and improvements that are included in this update
An IAG Detection Center feature is added that supports WMI detectionThis update introduces a Detection Center feature that enables Windows Management Instrumentation (WMI) detection on client computers. After you apply this update, IAG can detect client security applications by using the WMI interface in addition to the existing detection mechanism. This feature makes the following changes:
A registry entry is added to control the maximum size of a downloadable fileThe maximum size of a downloadable file is currently hardcoded to 10 megabytes. After you apply this hotfix, you can use a registry entry to set the maximum size of a downloadable file. For more information, see the "Registry information" section.

Registry informationImportant This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

Detection Center overviewWhen IAG client components are installed and enabled, Detection Center extends the existing IAG client detection capabilities by adding a WMI detection mechanism. For certain operating systems, Detection Center can retrieve all data that is stored in the WMI Security store.
On Windows XP Service Pack 2-based client computers, Detection Center can detect the antivirus applications and personal firewall applications that are installed on the system. On Windows Vista-based computers, Detection Center can also detect antispyware programs that are installed. This is because of the new WMI functionality that is introduced in Windows Vista. Future versions of Detection Center may detect additional applications or services.
The data that is collected from the WMI store, together with other data that is collected by the Endpoint Detection client component, is reported back to IAG. On the server that hosts IAG, IAG processes this data, and then it calculates the detection results. Then, the IAG policy engine checks for policy compliance against the detection results. During this process, users do not experience any changes in the existing policy enforcement behavior. Additionally, in the Policy Editor, an administrator will not notice significant changes when they are creating or managing policies. Administrators will notice only that some WMI detection-specific expressions were added. Administrators who use the Advanced Policy Editor may notice several new detection strings and some modifications to some default policies.
The following are the details about Detection Center.
The detection script
The policy template
The policy definitionThe policy definition file is updated to accommodate changes in the Policy Editor user interfaces if you add or edit a policy by using the Policy Editor instead of the Advanced Policy Editor. A list entry is added for the following expressions:
Note The Version field of the expressions is irrelevant. The Last Updated field of the Any WMI Anti-Virus entry contains an UptoDate value. If the UptoDate value is removed from the Last Updated field, the "Up To Date" WMI parameter is removed from the evaluation policy.
Translation from WMI variables to IAG legacy variablesWhen the client variables are sent to IAG, the WMI detection variables are translated into detection variables that are recognized by IAG. The translation process is performed by translation rules. In this process, all known vendors, versions, and editions that are retrieved from WMI are translated into detection variables that are recognized by IAG. For each retrieved WMI security variable, a WMI_NAME field is parsed to find matching text according to predefined translation rules. Currently, the most popular manufacturers and editions are translated by the built-in rules. You can easily expand the translation rules by adding new rules in the WmiTranslate.inc file in the following folder:
e-Gap\von\InternalSite\incNote The e-Gap placeholder represents the folder in which IAG or e-Gap Appliance is installed.
The System Information windowThe System Information window is updated. Green text that reads Up to Date appears next to the existing Update: Date/Time text if the following conditions are true:
If a product is detected by WMI and if no translation exists, no Update: Date/Time text is displayed. However, the Up to Date text is still displayed if the product is up to date.
