About this interactive

Firewalls, servers, endpoints, IDS and IPS, antivirus, EDR, DLP and the SIEM all log events. The lesson works through three problems that follow. First, the logs are scattered. In an incident nobody wants to sign in to every device. A log aggregation server takes all the logs in one place (log ingestion) and normalizes them so different formats can be searched together. Second, once the logs sit side by side, their timestamps have to agree, or events land in the wrong order and an attack's timeline cannot be rebuilt. Setting clocks by hand drifts. Network Time Protocol has every device check one time server so the clocks, and so the logs, line up. Third, each device has a logging level. A low level records everything, which gives the most visibility and costs the most processing and storage. A high level records only serious events, which is cheap but can miss what you need. Fix too much or too little by changing the level. Syslog is the usual protocol for shipping the events to the central server.

Key terms

Log Aggregation
The process of collecting and centralizing log data from multiple systems and devices into a single location for unified analysis and monitoring.
Network Time Protocol
NTP
A protocol that synchronizes the clocks of networked devices to a common reference time source using a hierarchy of time servers called strata, operating over UDP port 123. Accurate time synchronization is critical for security logging, authentication tickets, and correlating events across devices.
Logging
A monitoring method that records system or network events as they occur, creating an auditable history of activity.
Syslog
Syslog is a standard protocol for forwarding log messages from network devices and systems to a centralized log server, forming the foundation of security log collection pipelines and SIEM data ingestion.
Log Management
The process of collecting, storing, analyzing, and monitoring log data generated by systems and applications.
