Bob, a security specialist at an organization, extracted the following IIS log from a Windows-based...

In Microsoft IIS (W3C Extended) logging, each request line records multiple standardized fields that help investigators reconstruct what was accessed, by whom, and with what outcome. Among these fields, the most direct indicator of whether the server successfully handled the request is theHTTP status codecaptured in thesc-statusfield. A status code of200means“OK”, indicating the server located the requested resource (here,/images/content/bg_body1.jpg) and returned it successfully to the client without application-level failure.

Other numbers in the entry represent different attributes:80is the server port used for the HTTP request,192values appear as part of IP addressing (client/server addresses), and537is embedded in the user-agent string (AppleWebKit build number), not a success indicator. IIS often logs additional substatus and Win32 status values (e.g.,sc-substatusandsc-win32-status) to refine the outcome; in the shown line, those follow the 200 as “200 0 0 …”, reinforcing that no substatus error or OS-level error occurred. Therefore,200is the element confirming the request was fulfilled without error.
