Chapter 5      Managing Reusable Objects 
  Working with Security Intelligence Lists and Feeds
A Security Intelligence list is a simple static list of IP addresses and address blocks that you manually 
upload to the Defense Center. Custom lists are useful if you want to augment and fine-tune feeds or one 
of the global lists, for a single Defense Center’s managed devices.
Note that netmasks for address blocks can be integers from 
0
 to 
32
 or 
0
 to 
128,
 for IPv4 and IPv6, 
respectively. 
For example, if a reputable feed improperly blocks your access to vital resources but is overall useful to 
your organization, you can create a custom whitelist that contains only the improperly classified IP 
addresses, rather than removing the Security Intelligence feed object from the access control policy’s 
blacklist.
Note that to modify a Security Intelligence list, you must make your changes to the source file and 
upload a new copy. For more information, see
