Introduction
Why today's networks outgrow scattered logs, who this centralized log architecture guide is written for, and how to read its sections in order.
Why Centralize Logs
The five fundamental problems with distributed logs in large networks, and why centralization is an engineering answer rather than a matter of taste.
The Log Server Family
A tour of the five members of the central log server family, from the Syslog server through SIEM, SOAR and XDR, and how they stack.
Technical Architecture of the Log Pipeline
How one log message travels from creation to decision across six layers, from transport protocols to buffering, processing, and the data lifecycle.
SIEM In Depth
How a SIEM turns raw log data into security decisions through three pillars, five correlation rules, and threat intelligence enrichment, plus the limits of detection.
Operational Challenges and Privacy
Six challenges that decide whether central logging survives production, covering storage cost, data quality, SIEM security, privacy, time, and people.
Full Scenarios and Problem Solving
Three complete scenarios that connect every layer of a central log architecture, from a gradual breach through a network outage to post-incident compliance work.
Design Principles and the Final Checklist
Ten design principles, five architectural decisions, a five-phase rollout, and the mistakes that sink central logging projects, condensed into the checklist an architect should carry.
