Syslog

Syslog is a widely used method for transmitting and storing log messages across IT infrastructures. Network devices, servers, firewalls, routers, switches and other systems can send events to a central Syslog server. Messages typically contain information about system status, errors, security events or administrative activities. Syslog uses facility and severity values to categorise messages according to their source and importance. Depending on the implementation, messages can be transmitted using UDP, TCP or secured transport mechanisms. Centralised collection supports network monitoring, troubleshooting, security monitoring and IT system analysis. Syslog data can also be integrated into SIEM and observability platforms, allowing events from different systems to be correlated and security-relevant activities to be identified more efficiently.
