Find Relevant Case Skill

Identify existing SOAR 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

code
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:

code
secops-soar.get_case_full_details(case_id=candidate_case_id)

Outputs

OutputDescription
RELEVANT_CASE_IDSList of case IDs that match the search
RELEVANT_CASE_SUMMARIESBrief summaries (ID, name, priority)
FIND_CASE_STATUSSuccess/failure status of the search

Limitations & Workarounds

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

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