Consolidate 22 sibling repos into layered organism structure
Place useful parts of the surrounding repos into sica-fondt by layer, per the
body model (Ada = membrane; brain/endocrine/capabilities/knowledge non-Ada):

- brain/        LLM reasoning + providers (dapr, hermes, MoMoA)
- capabilities/ REPRAG sidecars: hermes tools/skills, dapr tools, parallel
                dispatch, A51 channels, and the OSINT cluster
- knowledge/    LORAG corpus: 754 cyber-skills, agency personas, secure-coding,
                MITRE ATT&CK data
- reference/    defensive threat-reference (C3, shhbruh doc) + AdaYaml parser

License handling: AGPL sources (worldosint, advanced_evolution, mercury,
Reticulum) and GPL DeTTECT are SPEC-only clean-room/port descriptions — no
copyleft code copied. MIT/Apache/data parts copied as working trees.

Safety: shhbruh escape/persistence material and C3 covert-C2 kept as reference
only, not wired into the running organism. See CONSOLIDATION.md.

Implementing SIEM Use Case Tuning

Overview

SIEM use case tuning reduces alert fatigue by systematically analyzing detection rules for false positive rates, adjusting thresholds based on environmental baselines, creating context-aware whitelists, and measuring detection efficacy through precision/recall metrics. This skill covers tuning workflows for Splunk correlation searches and Elastic detection rules, including statistical baselining, exclusion list management, and alert-to-incident conversion tracking.

When to Use

  • When deploying or configuring implementing siem use case tuning capabilities in your environment
  • When establishing security controls aligned to compliance requirements
  • When building or improving security architecture for this domain
  • When conducting security assessments that require this implementation

Prerequisites

  • Splunk Enterprise/Cloud with ES or Elastic SIEM with detection rules enabled
  • Historical alert data (minimum 30 days) for baseline analysis
  • Python 3.8+ with requests library
  • SIEM admin credentials or API tokens

Steps

  1. Export current alert volumes per detection rule from SIEM
  2. Calculate false positive rate per rule using analyst disposition data
  3. Identify top noise-generating rules by volume and FP rate
  4. Build environmental baselines for thresholds (e.g., login counts, process spawns)
  5. Create whitelist entries for known-good entities (service accounts, scanners)
  6. Adjust rule thresholds using statistical analysis (mean + N standard deviations)
  7. Measure tuning impact via before/after precision and alert-to-incident ratio

Expected Output

JSON report with per-rule tuning recommendations including current FP rate, suggested threshold adjustments, whitelist entries, and projected alert reduction percentages.
