To share IOC lists quickly for collaboration/integration, what should you do?

• A. Create a list in SecOps and grant required access to other teams.
• B. Export from GTI in CSV/JSON and email.
• C. Add IOCs to GTI collection and share.
• D. Create a new threat graph in GTI and share.

Answer: (A)

Sharing IOC lists quickly for collaboration is most effective when you use the SecOps system to create the list and control access to it. By building the IOC list inside SecOps and granting the appropriate access to other teams, you establish a single source of truth that stays up to date and is protected by proper permissions. This approach streamlines collaboration, eliminates the need to send ad hoc exports, and ensures all teams are working from the same data set.

Exporting from GTI to CSV or JSON and emailing distributes a static snapshot that can quickly become outdated and bypasses security controls, making it harder to manage who can view or update the data. Adding IOCs to a GTI collection and sharing can work in some contexts, but it may not provide the same centralized governance or the straightforward access controls needed for cross-team collaboration. Creating a new threat graph in GTI isn’t about distributing IOC lists; it’s a visualization of relationships, not a practical mechanism for sharing a ready-to-use IOC list.
