Feeds Scheduled for Deprecation in December 2024

The following feeds are approaching end of service and are being deprecated. In their place, Infoblox offers a set of new feeds designed to replace the deprecated feeds.

Deprecated Feeds	Description
Base Hostnames	Enables protection against known hostnames that are dangerous as destinations, such as APT, Bot, Compromised Host/Domains, Exploit Kits, Malicious Name Servers, and Sinkholes.
AntiMalware	Enables protection against known malicious hostname threats that can take action on or control of your system, such as Malware Command & Control, Malware Download, and active Phishing sites.
Ransomware	Enables protection against ransomware taking over your system. Ransomware will encrypt files on your system and require you to pay in order to get them decrypted. This feed prevents ransomware to contact the servers which it needs to encrypt your files.
Malware DGA Hostnames	Domain generation algorithm (DGA) are algorithms seen in various families of malware that are used to periodically generate a large number of domain names that can be used as rendezvous points with their command and control servers. Examples include Ramnit, Conficker, and Banjori.
Antimalware IP	Enables protection against known malicious or compromised IP addresses. These are known to host threats that can take action on or control of your system, such as Malware Command & Control, Malware Download, and active Phishing sites.
Suspicious	The Suspicious Domains feed enables protection against hostnames that have not been directly linked to malicious behavior but behave in a manner that suggests malicious behavior may be imminent.
Suspicious Lookalike	The Suspicious Lookalikes feed includes domains that appear to impersonate other trusted domains, but have demonstrated enough abnormal behavior to warrant concern.
Suspicious NOED	The Suspicious Emergent Domains feed include high risk, new domains. These domains have only recently become active, and share one or more characteristics with other known malicious domains to warrant concern.
Newly Observed Emergent Domains	The NOED feed includes recently created and newly active domain names. These are not necessarily suspicious but some organizations may wish to log traffic going to these domains as there is a low likelihood that these domains would be visited normally.

Deprecation of the Extended Feeds

With the deprecation of the old feeds and the release of the new feeds, infoblox will also be deprecating the extended feeds listed below. In the case of these feeds, they have lately been carrying zero indicators. Earlier when a malicious domain’s TTL expires, the domain was added to the corresponding Extended feeds, extending their lifetime. We updated that logic to verify the validity of the domain, on expiry. The domain is added to the same feed if it's still valid (as opposed to separate Extended feeds). As a result, the extended feeds were carrying zero indicators lately. At this point, we can effectively deprecate the below extended feeds.

Upgrading Policy Rules Using the New Feeds

Upgrading to Improve Policy Rules

Your security policies must be updated to adhere to the latest policy rules using the upgraded feed structure. The deadline for upgrading your security policies is December 31, 2024. Any policy that has not been updated after this date will be automatically upgraded.

To upgrade a policy, perform the following:

Navigate to the Security Policies page in the Cloud Services Platform ( Policies > Security Policies).
On the Security Policy tab, click the Upgrade link in the Upgrade Status column. Once the Upgrade link is clicked, the upgrade process is automatic. The upgrade process is non-reversible.
Policies that have been upgraded will display a green check along with an Upgrade Complete message. No further action is required with policies already upgraded. Policies requiring upgraded will display an Upgrade link. Clicking on the link will commence the upgrade process for the policy selected.
Out of respect for our customers, policy upgrades are not being conducted automatically. Instead, we offer our customers some latitude with upgrading their policies to a date and time they see fit, although do keep in mind that customers not having upgraded their policies by December 31st, 2024, will have their policies automatically upgraded on this date.

Only system administrators possess the required permissions to update a security policy.

Viewing Your Current Security Policy Rules

To view your current security policy rules, select a security policy and click on the three horizontal bars icon associated with it. From among the available options, click the Edit option followed by clicking the Policy Rules side menu item of the Edit Policy wizard. The current security policy configuration will be displayed.

The deprecated feeds are being incorporated into the new set of Infoblox feeds.

Viewing Your Upgraded Security Policy Rules

To view your upgraded security policy rules, select a security policy and click on the three horizontal bars icon associated with it. From among the available options, click the Edit option followed by clicking the Policy Rules side menu item of the Edit Policy wizard. The upgraded security policy configuration will be displayed.

Restricted Workflows for Old Security Policies Prior to Upgrading

Before upgrading a security policy, you won't be able to modify the current security policy configuration. While you can still view your existing security policies, making changes to non-upgraded policies will not be possible. Once you upgrade a current security policy, you will once again have the ability to edit and update it. When attempting to edit or change a non-upgraded security policy, the Finish button will be disabled.

Additionally, if you attempt to edit the Policy Rules page, then the Save & Close button on the Summary page will be disabled. However, you will still be able to view the policy configuration.

Logic for Upgrade Script

Logic for Upgrade Script
Step 1:
Logic Used: If all feeds in this section have the same action, then the new action retained on the converted new feeds will be the same as it was previously. If there are mixed actions among the feeds in this section, then the newly converted feeds will retain Block as the policy action, as this feed section is Critical Risk. Infoblox aims to ensure the protection of our customers during the conversion.
Case 1A (Best: No mix, all Block)		New Action
Base Hostnames	Block
AntiMalware	Block	Infoblox Base	Block
Malware DGA hostnames	Block
Ransomware	Block

Case 1B (Best: No Mix, all Allow)		New Action
Base Hostnames	Allow
AntiMalware	Allow	Infoblox Base	Allow
Malware DGA hostnames	Allow
Ransomware	Allow

Case 2 (possible: 1-2 mixed)		New Action
Base Hostnames	Block
AntiMalware	Block	Infoblox Base	Block
Malware DGA hostnames	Allow
Ransomware	Block

Case 3 (Worst: Most mixed)		New Action
Base Hostnames	Allow
AntiMalware	Block	Infoblox Base	Block
Malware DGA hostnames	Allow
Ransomware	Allow

Step 2:
Logic Used: If customers have any of the feeds listed below, Infoblox will add the new feed (with change of name). This new feed will maintain the same policy action as it did previously.
		New Action	Retained as is (in same precedence with same action), no change
Antimalware IP		Infoblox Base IP

Step 3:
Logic Used: If all feeds in this section have the same action, then the new action will be retained in the converted new feeds. If the feeds have mixed policy actions (i.e., even if one of the feed's action is Block), then in the converted new feeds, the action will be set to Block for High and Medium risks, while Low risk will be set to Allow with logging enabled. This section is NOT considered Critical Risk, and the indicators can fall into any of the three risk categories (High, Medium, and Low). In a mixed-case scenario, Infoblox aims to ensure that our customers are safeguarded against High and Medium risk indicators, while Low risk indicators can simply be logged.
Case 1A: (Best: No mix, all Block)		New Action
Suspicious	Block	Infoblox High Risk	Block
Suspicious Lookalikes	Block	Infoblox Med Risk	Block
Suspicious NOED	Block	Infoblox Low Risk	Block

Case 1B: (Best: No Mix, all Allow)		New Action
Suspicious	Allow	Infoblox High Risk	Allow
Suspicious Lookalikes	Allow	Infoblox Med Risk	Allow
Suspicious NOED	Allow	Infoblox Low Risk	Allow

Case 2: (Possible: 1 mixed)		New Action
Suspicious	Block	Infoblox High Risk	Block
Suspicious Lookalikes	Allow	Infoblox Med Risk	Block
Suspicious NOED	Allow	Infoblox Low Risk	Allow - with Log

Case 3: (Worst: 2 mixed)		New Action
Suspicious	Block	Infoblox High Risk	Block
Suspicious Lookalikes	Allow	Infoblox Med Risk	Block
Suspicious NOED	Block	Infoblox Low Risk	Allow - with Log

Step 4:
Logic Used: If customers possess any of the feeds mentioned below, Infoblox will introduce the new feed (with change of name) and apply the same policy action to them.
		New Action	Retained as is (in same precedence with same action), no change
NOED		Infoblox Informational

Note: All other supported rules are not changed and left as is - with the exiting rule action.
