Windows Firewall with Advanced Security in Windows 8

Security is an aspect that is taken into account today, especially when it comes to large companies where being well protected is a mandatory requirement and not something optional. With the combination of different tools one can increase security considerably, and sometimes many of them are provided by the operating system itself.

In our case, we will see what Windows 8 brings us regarding the integrated Firewall, and what aspects have changed compared to previous versions. The most obvious change for any user is the name change, since it now receives the Windows Firewall with Advanced Security

What is Windows Firewall with Advanced Security?

This is an important part of a layered security model, which basically means that the security level can be changed depending on the context(your computer, network, etc).

The Advanced Security Firewall service is capable of blocking unauthorized network traffic coming in and out of the local computer, thanks because it provides the equipment with bidirectional network traffic filtering. But also, as it is present in a layered security model, it is possible to apply security configurations according to the types of networks to which the computers connect.

In Windows 8, settings for Windows Firewall and Internet Protocol security (IPsec) are integrated into one place, called Windows Firewall with advanced security, which is why this service has also become a fundamental part of a network isolation strategy, and has undergone a change in its name as we have already mentioned.

What are its practical applications?

Reduces the risk of network security threats

Windows Firewall with Advanced Security reduces a computer's attack surface, providing an additional layer to the defense-in-depth model. By reducing the attack surface of a computer, you increase the computer's manageability and reduce the probability of successful attacks.

Protects sensitive data and intellectual property

With its integration with IPsec, Windows Firewall with Advanced Security provides an easy way to enforce end-to-end network communications so that both are identified. Provides scalable, tiered access to trusted network resources, helping to enforce data integrity and, optionally, protect confidentiality.

Extends the value of existing investments

Because Windows Firewall with Advanced Security is a host-based firewall that is included with Windows Server 2012, and with earlier Windows operating systems, no additional hardware or software is required. Windows Firewall with Advanced Security is also designed to complement existing non-Microsoft network security solutions through a documented application programming interface (API).
