Setting Scanning Exclusions
To save resources, you can configure scanning exclusions for IP addresses and ports that you know
are secure. For example, if your network includes a Web server that hosts Web pages that are
accessible by anyone on the Internet, the files that are hosted by your Web server do not need to be
scanned. To prevent the UTM from scanning these files, you can configure a scanning exclusion
for your Web server.
To configure scanning exclusion rules:
1. Select Application Security > Scanning Exclusions from the menu. The Scanning
Exclusions screen displays. This screen shows the Scanning Exclusions table, which is empty
if you have not specified any exclusions. (Figure 6-20 on page 6-45 shows one exclusion rule
in the table as an example.)
