How many security levels are supported by syslog?

Syslog supports eight security levels, which are part of its standardized categorization of severity levels for messages. These levels are structured to allow system administrators to understand the urgency and nature of logged events. The severity levels range from 0 to 7, where 0 indicates "Emergency" or "system is unusable," while 7 represents "Debugging" or detailed information used for troubleshooting purposes.

By supporting these eight levels, syslog provides a comprehensive system for categorizing messages, which helps in effective monitoring and management of network devices, applications, and systems. Thus, understanding these levels is essential for setting appropriate logging policies and for responding to various events in the context of network security and operational integrity.
