One of the elements that has a most relevant impact in Windows 11 is the Firewall, remember that this Firewall is responsible for protecting the computer from all incoming and outgoing network packets and data, it is ideal so that threats such as trojans or malware and applications that may contain malicious code inside..
Firewall Networks
The Windows 11 Firewall works on the networks that are available on the system, which are:
- Private network: it is a secure network and is ideal for use in our home or office, this network can be managed by the user, with this, Windows will allow all devices that are connected to the network to connect to each other.
- Public network: implies greater security since the user does not have full control of the configuration, this network is responsible for deactivating the visibility options of our device on the network, with this, not all peripherals will be visible from the external.
- Domain Network: As the name suggests, it is a network used within a domain, it can be Windows Server or Linux systems.
