Syslog Severity Values
Events can have security risks that can take many forms, for example:
- Threat actors that try to gain unauthorized, and undetected, access to an IACS network with the intention to commit malicious acts.
- Well-intentioned personnel with no malicious intention but who make mistakes that can result in unintended consequences.
The severity values are defined in The Syslog Protocol, RFC 5424, standard.
