Best firewall of top paid and free services | TechRadar
Windows Firewall has been enabled by default since Windows XP sp2, but I still see deployments where it is turned off because of old habits where it was difficult to determine how to allow applications through. But there can be times you should enhance the settings of the Windows firewall to better protect you from lateral movement and attackers.
If an application needs a special rule, you should build it based on the binary or executable, not the port. This ensures that the firewall opens only when the application is active. If you build a firewall rule using a port, that port remains open and exposes the system. Windows machines notify by default when an application is blocked. However, an IT administrator might want to use the event log to identify blocked applications rather than using the visual pop-ups in the system tray that can be easily missed.
To determine which applications Windows Firewall blocks, first search the event logs for event , which indicates that Windows Firewall blocked an application from accepting incoming connections on the network. Use this event to detect applications for which no Windows Firewall rules exist. If you are using a security event log monitoring solution to monitor events, keep the following in mind:.
You can use Windows Firewall to block applications accessing resources. This first rule below allows PowerShell to access a local subnet. The second rule drops traffic. This can protect your systems from attacks that leverage PowerShell to call command-and-control computers to launch ransomware and other attacks.
If PowerShell is intentionally made to hide itself by calling the binary from another location or by renaming itself, this process will not work. It will block attacks that target low-hanging fruit. You can set firewall rules with PowerShell as documented by Microsoft.
For example, to block outbound port 80 on a server, use the following PowerShell command:. You can use many PowerShell modules to better control and manage Windows Firewall.
