Find Relevant Case Skill

Identify existing cases that may be related to the current investigation based on IOCs, hostnames, usernames, or other entities.

Inputs

SEARCH_TERMS - List of values to search for (e.g., ["198.51.100.10", "mikeross-pc", "jsmith"])
(Optional) CASE_STATUS_FILTER - Filter by status: "Opened", "Closed" (default: "Opened")
(Optional) TIME_FRAME_HOURS - Lookback period for case creation/update
(Optional) MAX_RESULTS - Maximum cases to return

Workflow

Step 1: Construct Search Filter

Build a filter for list_cases based on search terms and filters.

Note: The list_cases tool may have limited ability to search within case entities. If direct entity search isn't supported, use broader filters and refine results.

Step 2: Execute Search

secops-soar.list_cases(
    filter=constructed_filter,
    limit=MAX_RESULTS
)

Step 3: Process Results

Extract case IDs and basic details (DisplayName, Priority) from results.

Step 4: (Optional) Refine Results

If too many results, use get_case_full_details on a subset to verify entity presence:

secops-soar.get_case_full_details(case_id=candidate_case_id)

Outputs

Output	Description
`RELEVANT_CASE_IDS`	List of case IDs that match the search
`RELEVANT_CASE_SUMMARIES`	Brief summaries (ID, name, priority)
`FIND_CASE_STATUS`	Success/failure status of the search

Limitations & Workarounds

The list_cases tool may not support direct entity searching. Alternatives:

Broader filters - Use time range, alert type, then manually review
SIEM correlation - Search SIEM for entity, check if events belong to a case
Multiple searches - Search each term separately, combine results
