In preparation of the August 2023 feed changes, Infoblox recommends the following rule action changes to your feed policy rules.

...

titleAlert

New feed recommendations: It is recommended that you do the following regarding the new feeds:

  • Add Suspicious Domains with one of the policy actions to Block.
  • Add Suspicious Lookalikes with one of the policy actions to  Block.
  • Add Suspicious NOED with one of the policy actions to  Block.

The following table includes the list of feeds that we will be retiring:

IP addresses are frequently reused for multiple sites, and blocking the ones associated with such systems ran the high risk of inadvertent blocking (I.E. False Positive). Many indicators here could be blocked in other ways, so the source is blocked in other similar feeds, making this redundant.

The curation process for these feeds (I.E. removing false positives) frequently left these feeds empty. The ones that remained are present in other feeds, making these feeds redundant.

For information on adding and removing feeds from a security policy, see the following: 

Note
title Feed Precedence Order
  • When configuring feed precedence order, Please remember to prioritize feeds configured with a Block action (Block - No Redirect, Block - Default Redirect, and/or Block - Redirect - <custom redirect name>) by placing them in positions of higher precedence in your policy compared to feeds configured with an Allow action (Allow - With Log, Allow - No Log, and/or Allow - Local Resolution).Placing Blocked feeds higher in policy precedence order than Allowed feeds ensures that your security policy performs as intended.
  • Ensure that you understand the ramification of overriding the default action for any threat feeds and Threat Insight rules before doing so.


Info

The recommended rule actions are for reference only. They represent the results of lab testing in a controlled environment focused on individual protocol services. Enabling additional protocols, services, cache hit ratio for recursive DNS, and customer environment variables will affect performance. To design and size a solution for a production environment, please contact your Infoblox Solution Architect.
