Module: CISCO-REMOTE-ACCESS-MONITOR-MIB

Description: The string identifying the version of the operating system of the entity which initiated this Remote Access session.
What is crasClientOSVersionString?
This object gives the specific operating-system version of the client machine that initiated this remote-access session, as self-reported by the client. Paired with crasClientOSVendorString, it lets an admin identify sessions coming from outdated or unpatched OS builds that may violate a security baseline before granting or continuing access. A concrete example: a value of '10.0.19045' identifies a Windows 10 22H2 build, while '6.1.7601' would flag an ancient Windows 7 SP1 machine still trying to connect.
