Server logging and log analysis
Server logging and log analysis help you find errors quickly, spot attacks early and investigate incidents.
Background
Web servers, applications and databases constantly log errors, slow requests, failed log-ins and suspicious access. Without analysis, these signals go unused.
Relevant logs
web server access and error logs
application logs, for example from Laravel or Statamic
records of log-ins and permission changes
firewall and web application firewall logs
Logs are kept on a separate system, where an attacker who takes over a server cannot erase them.
Central collection and analysis
With several servers, logs are collected in one searchable place. Rules detect clusters of errors or log-in attempts and trigger alerts.
Data protection and retention
Log files contain IP addresses and therefore personal data. Retention periods are short and documented, IP addresses are truncated where possible, and log rotation deletes old data automatically.
Approach
Work starts with a review of existing logs and retention periods. Under NIS2, logs underpin timely incident reporting. Your legal advisers can confirm whether NIS2 applies to you.
