Performing Application Filtering

ISA Server 2004 contains a number of built-in application filters to provide for application layer inspection of the corresponding traffic. Configuring the application filters is performed in various locations within the management console. For web filters, just right-click an HTTP or HTTPS rule anc select Configure HTTP. By default, Microsoft ISA Server 2004 supports the following HTTP applicatic filtering options:

• Maximum header length (in bytes)

• Maximum payload length (in bytes)

• URL length and query length protection (in bytes)

• URL normalization and high bit character blocking

• Windows executable blocking

• User defined HTTP method filtering (for example, denying POST methods)

• File extension filtering

• User-defined HTTP header content

• User-defined signature content filtering

For application filters, most can be managed from the add-ins screen, as shown in Figure 8-14.
