This article is to show you how to turn on this tracking feature to keep a much detailed log and how to access them.
To create a Windows Firewall log
You need to open Windows 8′s Windows Firewall with Advanced Security feature first. Press Win+R, type wf.msc, and press Enter. The targeted window will pops open.
Then, click Properties link on the right side of the screen. The following dialog box shows up.
Click Customize… button in the Logging section. In the dialog box that pops up, specify where you want to save the log file, the maximum log size, and whether to log dropped packets and successful connections. The dropped packets are those network traffics that have been blocked by Windows Firewall. And a successful connection refers to both incoming connections as well as any connections you have made over to the Internet. I selected “Yes” on both options in this case.
You will have to repeat this step to Public Profile tab as well as Private Profile tab so you have the same logging setting in place for all 3 types of firewall profiles.
To access the log file
Back to the main Windows Firewall and Advanced Security window. Click Monitoring on the left side panel, locate the Logging Settings section in the middle side of panel, and click the file link for the log file.
The log will open in Notepad automatically. It may look gibberish but it does contain a lot of useful information there. Each log entry has a total of up to 16 pieces of information but the most useful ones are the first eight columns, which include Date, Time, Action, Protocol, Source IP, Destination IP, Source Port, and Destination Port.
It may not necessary checking the log file each day if your PC is behind your router but still, it would be a good idea turning this log on and assess it regularly once a while to make sure you are in a safe zone for you computer.
The title of this post says for Windows 8 but it should work the same for Windows 7 computers as well.
