Windows Defender Firewall med avanceret sikkerhed^{(Windows Defender Firewall with Advanced Security)} leverer fordelene ved at bruge disse funktioner:

• Indgående og udgående regler
• Forbindelsessikkerhedsregler
• Overvågning

Hvad er reglerne for indgående og udgående?

For at give den sikkerhed, du har brug for, har Windows Defender Firewall et standardsæt af indgående og udgående regler, som er aktiveret afhængigt af placeringen af ​​det tilsluttede netværk^{(location of the connected network)} .

Indgående regler anvendes på den trafik, der kommer fra netværket og internettet til din Windows -computer eller -enhed. Udgående regler gælder for trafikken fra din computer til netværket eller internettet^(Internet) .

Disse regler kan konfigureres, så de er specifikke for computere, brugere, programmer, tjenester, porte eller protokoller. Du kan også specificere, hvilken type netværksadapter (f.eks. trådløs, kabel, virtuelt privat netværk) eller brugerprofil den er anvendt på.

I Windows Defender Firewall med avanceret sikkerhed^{(Windows Defender Firewall with Advanced Security)} kan du få adgang til alle regler og redigere deres egenskaber. Alt du skal gøre er at klikke eller trykke på den relevante sektion i panelet til venstre.

Reglerne, der bruges af Windows Defender Firewall , kan aktiveres eller deaktiveres. De, der er aktiveret eller aktive, er markeret med et grønt afkrydsningsfelt i kolonnen Navn .^(Name)

Lad os som eksempel vælge en af ​​reglerne for Windows Media Player Network Sharing Service . Hvis du administrerer dit mediebibliotek på din Windows -enhed med Windows Media Player , kan du beslutte at dele det over netværket. Reglerne til dette formål er deaktiveret som standard (det grønne afkrydsningsfelt mangler ud for deres navne).

Hvis du vil vide mere om en bestemt regel og se dens egenskaber, skal du højreklikke på den og vælge Egenskaber^(Properties) eller vælge den og trykke på Egenskaber^(Properties) i kolonnen til højre, som viser de handlinger, der er tilgængelige for dit valg.

I vinduet Egenskaber^(Properties) finder du fuldstændig information om den valgte regel, hvad den gør, og hvornår den anvendes. Du kan også redigere dens egenskaber og ændre enhver af de tilgængelige parametre. For at aktivere reglen i vores eksempel skal du markere afkrydsningsfeltet Aktiveret^(Enabled) og trykke på OK- knappen.

Når vi vender tilbage til vinduet Windows Defender Firewall med avanceret sikkerhed^{(Windows Defender Firewall with Advanced Security)} , har reglen det grønne afkrydsningsfelt, der viser, at det er aktiveret.

Hvad er reglerne for forbindelsessikkerhed^{(Connection Security Rules)} ?

Forbindelsessikkerhedsregler^(Connection) bruges til at sikre trafik mellem to computere, mens den krydser netværket. Et eksempel kunne være en regel, der definerer, at forbindelser mellem to specifikke computere skal være krypteret. Disse regler definerer, hvordan og hvornår computere godkendes ved hjælp af IPsec ( Internet Security Protocol ).

Mens de indgående eller udgående regler kun anvendes på én computer, kræver forbindelsessikkerhedsregler, at begge computere har de samme regler defineret og aktiveret. Hvis du vil se, om der er sådanne regler på din computer, skal du klikke eller trykke på "Connection Security Rules" på panelet til venstre. Som standard er der ikke defineret sådanne regler på Windows -computere og -enheder. De bruges generelt i forretningsmiljøer, og netværksadministratoren sætter sådanne regler.

Windows Defender Firewall with Advanced Security: What is it? How to open it? What can you do with it?

The Windows Defender Firewall with Advanced Security is a tool which gives you detailed control over the rules that are applied by the Windows Defender Firewall. You can view all the rules that are used by the Windows Defender Firewall, change their properties, create new rules or disable existing ones. In this tutorial, we share how to open the Windows Defender Firewall with Advanced Security, how to find your way around it, and talk about the types of rules that are available and what kind of traffic they filter.

NOTE: This guide covers Windows 10, Windows 7, and Windows 8.1. If you do not know the version of Windows that you have, read this tutorial: What version of Windows do I have installed?.

What is Windows Defender Firewall with Advanced Security?

First, let's clarify the name. The native firewall in Windows is named Windows Defender Firewall in Windows 10 while in Windows 7 and Windows 8.1 it retains the old name of Windows Firewall. Similarly, the tool we cover in this tutorial is named Windows Defender Firewall with Advanced Security in Windows 10 and Windows Firewall with Advanced Security in Windows 7 and Windows 8.1. The tool looks and functions identically in all three Windows versions. For this article, we use screenshots from Windows 10 and use the name Windows Defender Firewall with Advanced Security, but our tutorial is valid for all three Windows versions.

Windows Defender Firewall helps secure your Windows device by filtering the network traffic permitted to enter or exit your device. The tool is built as a snap-in on the Microsoft Management Console, and its executable file is named wf.msc. For more details on Windows Defender Firewall, read What is the Windows Firewall and how to turn it on or off?.

Control Panel provides a couple of basic settings for Windows Defender Firewall while Windows Defender Firewall with Advanced Security gives you access to all its features. Windows 10 has introduced basic firewall settings in its Settings app, but for full control of Windows Defender Firewall, it sends you to the Windows Defender Firewall with Advanced Security.

How to access the Windows Defender Firewall with Advanced Security

The easiest method to open Windows Defender Firewall with Advanced Security in all three Windows versions is to search for its executable file. Type "wf.msc" in the Windows search box and click or tap on the result.

In Control Panel you can access the Windows Defender Firewall with Advanced Security by going to "System and Security -> Windows Defender Firewall," and then by clicking or tapping Advanced settings.

In Windows 10, you can find a shortcut for Windows Defender Firewall with Advanced Security in the Start Menu using the following path: "Start Menu → Windows Administrative Tools → Windows Defender Firewall with Advanced Security."

What can you do with Windows Defender Firewall with Advanced Security?

The tool gives you access to all the features of Windows Defender Firewall. Here are some of the benefits of using it:

• Reduces the risk of security attacks from the network. Windows Defender Firewall is not a complete security solution, but it reduces the chances of a successful network attack.
• Authenticates access to your device. It can do it using IPsec (Internet Protocol Security), which enforces the integrity of data and protects confidentiality.
• Provides firewall capability with no additional investment. Windows Defender Firewall is part of Windows. You get the firewall without spending money or installing additional software.

Windows Defender Firewall with Advanced Security delivers the benefits using these features:

• Inbound and Outbound Rules
• Connection Security Rules
• Monitoring

What are the inbound and outbound rules?

To provide the security you need, the Windows Defender Firewall has a standard set of inbound and outbound rules, which are enabled depending on the location of the connected network.

Inbound rules are applied to the traffic that is coming from the network and the internet to your Windows computer or device. Outbound rules apply to the traffic from your computer to the network or the Internet.

These rules can be configured so that they are specific to computers, users, programs, services, ports or protocols. You can also specify to which type of network adapter (e.g., wireless, cable, virtual private network) or user profile it is applied.

In the Windows Defender Firewall with Advanced Security, you can access all rules and edit their properties. All you have to do is click or tap the appropriate section in the left-side panel.

The rules used by the Windows Defender Firewall can be enabled or disabled. The ones which are enabled or active are marked with a green checkbox in the Name column.

Let's pick as an example one of the rules for Windows Media Player Network Sharing Service. If you manage your media library on your Windows device with Windows Media Player, you can decide to share it over the network. The rules for this purpose are disabled by default (the green checkbox is missing next to their names).

If you want to know more about a specific rule and see its properties, right click on it and select Properties or select it and press Properties in the column on the right, which lists the actions that are available for your selection.

In the Properties window, you find complete information about the selected rule, what it does and when it is applied. You can also edit its properties and change any of the available parameters. To enable the rule in our example, mark the checkbox Enabled and press the OK button.

When we return to the Windows Defender Firewall with Advanced Security window, the rule has the green checkbox showing it is enabled.

For more details on managing these rules, read How to Add & Manage Rules in the Windows Firewall with Advanced Security.

What are the Connection Security Rules?

Connection security rules are used to secure traffic between two computers while it crosses the network. One example would be a rule which defines that connections between two specific computers must be encrypted. These rules define how and when computers are authenticated using IPsec (Internet Security Protocol).

While the inbound or outbound rules are applied only to one computer, connection security rules require both computers to have the same rules defined and enabled. If you want to see if there are any such rules on your computer, click or tap "Connection Security Rules" on the panel on the left. By default, there are no such rules defined on Windows computers and devices. They are generally used in business environments, and the network administrator sets such rules.

Windows Defender Firewall with Advanced Security - What does it monitor?

The Windows Defender Firewall with Advanced Security includes some monitoring features as well. In the Monitoring section you can find the following information: the firewall rules that are active (both inbound and outbound), the connection security rules that are active and whether there are any active security associations.

You should note that the Monitoring section shows only the active rules for the current network location. If there are rules which get enabled for other network locations, you do not see them in this section.
