Tag massive and internal IOCs to avoid EDL listing

This Playbook is part of the Generic Export Indicators Service Pack.

Supported versions

Supported Cortex XSOAR versions: 5.5.0 and later.

This playbook tags internal assets and massive IOCs (TLD wildcards and CIDRs) to be avoided by the EDL. The playbook does the following according to indicator type:

• CIDRs - If the CIDR prefix is larger than the set max prefix it tags it with Massive_CIDR and also with skip_edl.
• TLD Wildcards - If a DomainGlob is a TLD wildcard (for example *.net) it tags it with TLD_Wildcard and also with skip_edl.
• Internal IPs - If an IP is internal and also part of the CIDR configured by the user in the "Internal Assets" list it is checked as internal and tagged with skip_edl.
• Internal Domains - If a domain is a subdomain of the domains configured in the "Internal Assets" list it is checked as internal and tagged with skip_edl.

We recommend running the playbook as a job to keep tags up to date on new indicators.
