Which of The Following is a Firewall Function?


A firewall function is a security feature that helps protect your computer from unauthorized access. It allows you to block specific types of traffic, and can help protect your system from malware and other malicious attacks.

What is a firewall function?

A firewall function is a computer security feature that allows administrators to control which computers and networks can access the network.

How do firewalls work?

A firewall is a device or software that protects computer networks and data from unauthorized access. Firewalls work by blocking requests for resources that are not intended to be accessible by the computer on which they reside.

What are the benefits of using a firewall?

There are many benefits to using a firewall, the most obvious of which is the prevention of malicious attacks. A firewall also helps to protect your network from unauthorized access, provides security for online transactions, and can even help to protect your computer from viruses.

Types of firewalls

A firewall is a technology that blocks unauthorized access to computer networks. There are many different types of firewalls, but the most common are application, network, and host-based firewalls. Application firewalls protect individual applications from being accessed by other users or processes on the network. Network firewalls protect the computer networks themselves from unauthorized access by blocking incoming traffic. Host-based firewalls protect individual computers on a network from unauthorized access by blocking incoming traffic at the OS level.

In order to provide the best protection for your computer, it is important to know what type of firewall you have and what its capabilities are. This article will discuss some of the most common types of firewalls and their uses.

How to set up a firewall on your computer?

Setting up a firewall on your computer is an essential security measure. A firewall protects your computer against unauthorized access and use, and can help to protect your data. There are many different types of firewalls available, but this guide will teach you how to set up a basic firewall on your computer using Windows 7.

To start, open the Control Panel by pressing the Windows key + X and selecting Control Panel from the list of results. If you’re using Windows 8 or 10, click in the bottom left corner of the screen, type “Control Panel” into the search box, and select it from the results.

Next, click on System and Security > Security Settings. This will open the Security Settings window. Under network security, click on Internet Protocol Version 4 (TCP/IPv4) settings.

In the TCP/IPv4 settings window, make sure that the Enable TCP/IP Firewall option is selected. Click on OK to close the TCP/IPv4 settings window.

Now that we have our firewall enabled, we need to create a rule for it. To do this, click on Firewall with Advanced Security in the left column of the Security Settings

Which of the following is a firewall function?

A firewall function is a process or program that helps protect your computer from unauthorized access by preventing access to certain ports or networks.

Frame filtering

A firewall function is a process or program that helps protect computer networks by blocking or restricting the flow of traffic. Some common firewall functions include:

  • Blocking ports: Port filtering allows certain ports on a computer to be opened only by specific applications, while firewalling restricts all traffic to and from a specific IP address or host.
  • Filtering protocols: Firewalls can also filter which protocols are allowed through the firewall. For example, you might want to allow HTTP traffic but block UDP and ICMP packets.
  • Filtering content: Firewalls can also filter the content of packets, meaning they can block certain types of files, URLs, or network traffic.

Packet filtering

A firewall function is a process or program that helps protect computers and networks by blocking or allowing traffic according to defined rules.


In this conclusion paragraph, I will be discussing what a firewall function is and how it can help protect your computer from online threats. A firewall functions as the first line of defense against potential attacks on your computer, by blocking unsolicited traffic and protecting your system from unauthorized access. By understanding how a firewall works, you can better protect yourself from viruses, spyware, and other malicious software that may present an inherent threat to your computer.
