You most likely know that it has a built-in firewall. You may also know how to allow and block access of individual programs to the network in order to control incoming and outgoing traffic. But did you know that Windows firewall can be used to log all connections passing through it?

Windows Firewall logs can be useful in solving specific problems:

The program you are using cannot connect to the Internet, although other applications do not experience this problem. IN in this case To troubleshoot the problem, you should check whether the system firewall is blocking the connection requests of this program.
You suspect that the computer is being used to transfer data malware and want to monitor outgoing traffic for suspicious connection requests.
You have created new rules for allowing and blocking access and want to ensure that the firewall correctly processes the given instructions.

Regardless of the reason for use, enabling event logging can be challenging task, as it requires a lot of manipulation with the settings. We will provide a clear algorithm of actions on how to activate registration network activity in the Windows firewall.

Access to firewall settings

First, you need to go to advanced settings Windows Firewall. Open the control panel (click right click mouse on the Start menu, “Control Panel” option), then click the “Windows Firewall” link if the view mode is small/large icons, or select the “System and Security” section, and then “Windows Firewall” if the view mode is category .

In the firewall window, select the option on the left navigation menu “Extra options”.

You will see the following settings screen:

This is the internal technical side of the Windows Firewall. This interface allows you to allow or block access of programs to the Internet, configure incoming and outgoing traffic. In addition, this is where you can activate the event logging feature - although it is not immediately clear where this can be done.

Accessing log settings

First, select the option “Windows Firewall in increased security(Local computer)".

Right-click on it and select the “Properties” option.

A window will open that may confuse the user. When you select three tabs (Domain Profile, Private Profile, Public Profile), you will notice that their content is identical, but relates to three different profiles, the name of which is indicated in the tab title. Each profile tab contains a button to configure logging. Each log will correspond to a different profile, but which profile are you using?

Let's look at what each profile means:

A domain profile is used to connect to wireless network Wi-Fi when the domain is set by the domain controller. If you are not sure what this means, please do not use this profile.
The private profile is used to connect to private networks, including home or personal networks- this is the profile you will most likely use.
The general profile is used to connect to public networks, including chains of restaurants, airports, libraries and other institutions.

If you are using a computer in home network, go to the “Private Profile” tab. If used public network, go to the “General Profile” tab. Click the “Configure” button in the “Logging” section on the correct tab.

Activating the event log

In the window that opens, you can configure the location and maximum size magazine. You can set an easy-to-remember location for the log, but the actual location of the log file doesn't really matter. If you want to start event logging, set both the “Log missed packets” and “Log successful connections” drop-down menus to “Yes” and click the “OK” button. Full time job This feature may cause performance problems, so only enable it when you really need to monitor connections. To disable the logging feature, set the value to “No (default)” in both drop-down menus.

Studying logs

Now the computer will record network activity controlled by the firewall. To view the logs, go to the “Advanced Settings” window, select the “Monitoring” option in the left list, and then in the “Logging Options” section click the “File Name” link.

The network activity log will then open. Log Contents Can Be Confusing inexperienced user. Let's look at the main contents of the log entries:

Date and time of connection.
What happened to the connection? The status “ALLOW” means that the firewall allowed the connection, and the status “DROP” indicates that the connection was blocked by the firewall. If you encounter network connection problems separate program, you can determine for sure that the cause of the problem is related to the firewall policy.
Connection type - TCP or UDP.
In order: IP address of the connection source (computer), destination IP address (for example, a web page), and used on the computer network port. This entry allows you to identify ports that require opening for the software to work. Also watch out for suspicious connections - they could be made by malware.
Whether the data packet was successfully sent or received.

The information in the log will help determine the cause of connection problems. The logs can record other activity, such as the target port or TCP acknowledgment number. If you need more details, check out the “#Fields” line at the top of the log to identify the meaning of each metric.

Don't forget to turn off the logging feature when you're done.

Advanced network diagnostics

By using Windows Firewall logging, you can analyze the types of data being processed on your computer. In addition, you can determine the causes of network problems related to the firewall or other objects disrupting connections. The activity log allows you to familiarize yourself with the work of the firewall and get a clear picture of what is happening on the network.
