Web server logs

When reviewing web server logs, pay particular attention to the web servers that have web applications interacting with SQL databases.

The IIS Web server log files are located at \WINDOWS\system32\LogFiles\W3SVC1 and they are .log files that can be opened using Notepad. You can also use Excel or Microsoft Log Parser to open this file and perform basic queries.

You can download Log Parser from https://www.microsoft.com/en-us/download/details.aspx?id=24659.
