The Evolution of Network Forensics: From Bytes to Brains

Introduction

Network forensics has evolved dramatically, from manual packet analysis to AI-powered threat detection and automated incident response.

The Early Days

Manual Analysis

• Packet capture and review
• Log file examination
• Signature-based detection

Limitations

• Time-intensive processes
• Reactive rather than proactive
• Difficulty with volume

The Rise of Automation

Automated Collection

Systematic capture of network data.

Signature Detection

Matching known attack patterns.

Log Aggregation

Centralizing data for analysis.

AI-Powered Forensics
