- Add validated mitre_attack frontmatter to all 754 skills (286 distinct
techniques), verified against MITRE ATT&CK v19.1 via the official
mitreattack-python library: 0 revoked, deprecated, or invalid IDs
- Curate precise per-skill technique IDs for forensics, malware-analysis,
threat-intel, and red-team skills (e.g. DCSync -> T1003.006,
Kerberoasting -> T1558.003, Pass-the-Ticket -> T1550.003)
- Reconcile v19.1 tactic restructuring: Defense Evasion split into
Stealth (TA0005) and Defense Impairment (TA0112); revoked T1562.*
family and T1070.001/.002 remapped to active equivalents (T1685.*)
- Normalize word-split tags across 35 skills (remove filename-derived
stopword tags, add semantic cybersecurity tags)
- Add api-reference.md for 3 skills that were missing it

Implementing Log Forwarding with Fluentd
Overview
This skill covers configuring Fluentd and Fluent Bit for centralized log collection, routing, and enrichment. Fluent Bit acts as a lightweight log forwarder on endpoints, while Fluentd serves as the central aggregator and processor. The configuration covers input plugins for syslog, file tailing, and application logs, with output routing to Elasticsearch, S3, and Splunk.
When to Use
When deploying or configuring implementing log forwarding with fluentd 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
Fluentd (td-agent) v1.16+ or Fluent Bit v3.0+
Python 3.8+ with fluent-logger library
Elasticsearch or Splunk for log destination
Network access on port 24224 (Fluentd forward protocol)
Ruby 2.7+ (for Fluentd plugin development)
Steps
Generate Fluent Bit Configuration — Create input, filter, and output configuration for endpoint log collection
Generate Fluentd Aggregator Configuration — Configure the central Fluentd instance with forward input, parsing, and multi-output routing
Configure Log Filtering and Enrichment — Add record_transformer and grep filters for log enrichment and noise reduction
Validate Configuration Syntax — Parse and validate Fluentd/Fluent Bit configuration files for syntax errors
Test Log Forwarding — Send test events via fluent-logger Python library and verify delivery
Generate Deployment Report — Produce configuration summary with routing topology and health metrics
Expected Output
Fluent Bit and Fluentd configuration files (INI/YAML format)
