CLASSIFIED OPERATION: SECURITY OPERATIONS, LOG INGESTION & THREAT CORRELATION
STATUS: CONCLUDED | AUTHOR: MR. CIPHER-X [C|THE]

🛡️ Operation Abstract

This repository details the architecture and execution of a centralized Security Operations Center (SOC) log analysis pipeline. The objective was to ingest diverse telemetry sources (Endpoints, Firewalls, Web Servers), parse the raw data, and write custom SIEM correlation rules to detect persistent threats, brute-force attempts, and lateral movement in real-time.

🦠 Threat Detection Matrix (Correlation Rules)

Threat Vector	Log Source / Event ID	Detection Logic (SIEM Query Base)	Tactical Response
Active Directory Brute Force	Windows Security Logs (Event ID: 4625)	Count > 10 failed logins within 5 mins from a single IP.	Automate IP block at perimeter firewall.
Privilege Escalation	Linux auth.log / secure	Unauthorized user executing sudo su or adding to wheel group.	Trigger high-severity alert, isolate endpoint.
Web Application Attack (SQLi)	Apache / Nginx Access Logs	HTTP GET/POST containing anomalous characters (' OR 1=1--).	Blacklist source IP, review WAF configurations.
