Windows Defender Firewall - Week 4

Windows Defender Firewall - Week 4 

The Windows Defender firewall plays a crucial role in keeping your network secure, but how does it do that? It does this by filtering traffic coming in and out of your network and blocking suspicious connections.

 

You can turn on your Windows Defender firewall (assuming its Windows) on your device system settings . By default, the Windows firewall offers a fair level of security, it allows common applications and services to operate while blocking suspicious or harmful connections.

 

Once your firewalls are on, we can click on "Advanced Settings". Where we can personalise and view current inbound and outbound rules, exceptions, monitor active settings, and diagnose/repair the firewall.

 

 We can configure the Windows firewall further by applying:

Inbound and Outbound Rules – Establishing inbound rules that apply to incoming internet traffic and outbound rules for traffic departing your computer. 

Connection Security Rules – Enhancing the security of traffic exchanged between two computers, requesting that both computers employ identical, defined, and enabled rules.

Monitoring – Shows active inbound or outbound firewall rules, as well as any currently active connection security rules.

Configuring Exceptions

To allow or deny access to specific programs or ports on a firewall, you should open the windows firewall window and click on "allow an app or feature through windows firewall".

From here you will be allowed to:

• Add trusted programs or ports
• Make changes to current programs or ports
• Remove a current allowed program or port
