# Standards and Frameworks for Timeline Analysis

## NIST SP 800-86 - Guide to Integrating Forensic Techniques
- Provides guidelines for collecting, examining, and analyzing digital evidence
- Emphasizes importance of timeline reconstruction in incident investigation
- Defines evidence handling procedures for forensic analysis

## SANS FOR508 - Advanced Incident Response, Threat Hunting, and Digital Forensics
- Super timeline creation methodology
- Evidence source prioritization for timeline building
- Plaso/log2timeline artifact parsing techniques
- Timeline analysis for APT detection

## RFC 3339 / ISO 8601 - Timestamp Standardization
- Standard format for representing dates and times in timelines
- Timesketch normalizes all timestamps to UTC ISO 8601 format
- Ensures consistent chronological ordering across diverse sources

## DFRWS (Digital Forensic Research Workshop) Standards
- Forensic timeline analysis research and best practices
- Timesketch presented at DFRWS conferences as reference implementation
- Evidence integrity and chain of custody in digital forensics

## Plaso/log2timeline Documentation
- Official parser documentation for 200+ artifact types
- Filter file syntax for targeted evidence collection
- Output format specifications for Timesketch integration
- Reference: https://plaso.readthedocs.io/

## OpenSearch/Elasticsearch Indexing Standards
- Event storage and retrieval optimization
- Index lifecycle management for large investigations
- Query DSL for advanced timeline searching

## Sigma Detection Standard
- Open signature format for SIEM systems
- Timesketch Sigma analyzer integration
- Community detection rules for common attack patterns
- Reference: https://github.com/SigmaHQ/sigma

## MITRE ATT&CK Framework Integration
- Mapping timeline events to ATT&CK techniques
- Tactic-based timeline segmentation
- Attack chain reconstruction methodology
