Blumira Resolutions

Blumira Resolutions

Overview

Resolutions are the final disposition applied to findings when closing them. Choosing the correct resolution type is critical for accurate security metrics, detection tuning, and compliance reporting.

Anti-triggers

• Triaging, investigating, assigning, or commenting — this skill covers only the disposition decision at close. The rest of the lifecycle is blumira-findings (or blumira-msp for a client account).
• blumira_resolutions_list — that tool enumerates the resolution catalogue and is unrelated to remediation actions; Blumira cannot isolate, block, or kill anything.
• Huntress remediation approve/reject — superficially similar close-out language, entirely different mechanics (Huntress acts on the endpoint). Use huntress-incidents.

Key Concepts

Resolution Types

Impact on Metrics

• Valid resolutions count toward your confirmed threat statistics
• False Positive resolutions feed back into detection tuning — high FP rates indicate rules that need adjustment
• Not Applicable resolutions help identify rules to disable for specific environments

API Patterns

List Available Resolutions

blumira_resolutions_list

Returns all resolution types with their codes, labels, and descriptions.

Resolve a Finding

blumira_findings_resolve
  finding_id=<UUID>
  resolution_type=10
  notes="Confirmed credential stuffing attack from IP 203.0.113.50. Account locked, password reset forced."

MSP Finding Resolution

blumira_msp_findings_resolve
  account_id=<UUID>
  finding_id=<UUID>
  resolution_type=30
  notes="False positive - scheduled backup job triggers this detection. Added to allowlist."

Common Workflows

Choosing the Right Resolution

1. Is the detected activity real?

   • Yes → Was it malicious or a policy violation? → Valid (10)
   • Yes → But it's expected/allowed in this environment → Not Applicable (20)
   • No → The detection was wrong → False Positive (30)

2. Always include detailed notes explaining the decision

3. For False Positives, note what the activity actually was to help with tuning

Bulk Resolution of False Positives

1. blumira_findings_list filtered by the specific detection rule
2. Review a sample to confirm all are false positives
3. Resolve each with resolution type 30 and consistent notes
4. Consider requesting a rule tuning in the Blumira portal

Error Handling

Invalid Resolution Type

Cause: Resolution code is not 10, 20, or 30 Solution: Use blumira_resolutions_list to confirm valid codes.

Missing Notes

Cause: Some resolution workflows may require notes Solution: Always provide descriptive notes for audit trail purposes.

Best Practices

• Track false positive rates by detection rule to identify tuning opportunities
• Use "Not Applicable" instead of "False Positive" when the detection is correct but the policy doesn't apply
• Review resolution statistics regularly to improve detection quality
• For MSP accounts, maintain consistent resolution standards across tenants
