Most of the computer users are familiar with the term Firewall. Firewalls are Hardware devices or Software programs that monitor incoming and outgoing connections analyzing the packet data for malicious behavior. Like the definition says, there are both Software and Hardware Firewalls. In this modern age, we are literally at war with hackers and malware and virus developers, all the time and data security has become the number one concern. To protect our computers, we use security software like AntiVirus and Firewalls – and as we just mentioned, there are two kinds of firewalls – Hardware firewalls and Software firewalls.
Hardware firewall vs Software firewall. In computing, a firewall refers to a system that shields a private network or stand alone computer system from malicious internet traffic, unauthorized remote access or any kind of attack. Firewalls can be used to control access to a particular system within a network for instance a corporate network of a. Hardware firewall is a piece of networking equipment that is dedicated to provide a protective barrier that protects the internal computer for the outside internet (4). Differ from software firewall which only provide protection on the computer that installed the firewall, the hardware firewall protects each single computer connected to it. Software Firewall. A software firewall is more of an individual machine thing when the number of users are relatively less in an organization. However, in larger organizations, in spite of a Hardware Firewall security, it is recommended to use a Software firewall as well.
Hardware firewall vs. Software firewall
In this article, we’ll talk about the difference between Software Firewall & Hardware Firewall.
Hardware Firewall
Hardware Firewalls are mostly seen in broadband modems, and is the first line of defense, using Packet Filtering. Before an Internet packet reaches your PC, the Hardware Firewall will monitor the packets and check where it comes from. It also checks if the IP address or header can be trusted. After these checks, the packet then reaches your PC. It blocks any links that contain malicious behavior based on the current Firewall setup in the device. A Hardware Firewall usually does not need a lot of configuration. Most of the rules are built-in and predefined and based on these inbuilt rules; the Packet Filtering is done.
Today’s technology has improved so much that it not just the traditional Packet Filtering which is carried out. The Hardware Firewall has built-in IPS / IPDS (Intrusion Prevention Systems), that earlier used to be a separate device. But now these are included, offering us greater protection.
When an IPDS detects a malicious activity, it sends and signal and reset the connection and blocks the IP address. It uses signature-based, statistical anomaly-based, and stateful protocol analysis. You can read more about this here. But the main drawback I find is that it allows all the outgoing packets, i.e., if by chance, a malware got into your system and started transmitting data, it would be allowed unless the user became aware of it, and decided to stop it. But in most cases, this does not happen.
Hardware Firewall Vs Software Firewall Free
Hardware Firewall is typically good for small or medium business owners, with 5 or more PC or a co-operate environment. The main reason is that it then becomes cost-effective because if you’re to purchase Internet Security/Firewall software licenses for 10 to 50 copies, and that too on an annual subscription basis, it will cost a lot of money and deployment could also be an issue. The users will have better control over the environment. If the user is not tech savvy and if they choose to inadvertently allow a connection that has Malware behavior, it could ruin the entire network and put the company at risk with data security. A hardware firewall could thus be very useful in such cases.
There is no real difference between so-called 'hardware' and so-called 'software' firewalls. They all use hardware to run software. So-called 'hardware' firewalls run a software operating system no different from anything else. In fact a number of 'hardware firewall' vendors run the same underlying FreeBSD and other components as pfSense. Visit the online HomeUsers Store or the Enterprise Store to find about the latest Panda product portfolio. Additionally, you can access the Technical Support page, where online solutions for all the current Panda products are provided.
There are always few things you have to consider before buying a Hardware-based firewall. The number of users in your network, the number of VPN users in your network, because under-estimating the number could exhaust the performance of your device and affect the performance of the Internet connection as well. Also, make sure you have enough license for VPN client connection, and it has SSL, PPTP, etc. connection support too. Even if you have to pay a subscription, go for it – because a subscription means that you get the latest definitions.
Manufacturers are now including Gateway Antivirus, Malware scanners, and Content Filters, so you’ll get maximum protection with them. For example, CISCO Hardware includes “Cisco ProtectLink Security Solutions” on selected devices. It addresses a specific security threat, and as part of an overall security, approach provides layers of protection against different threats.
There are a lot of companies you can choose from like CISCO, SonicWall, Netgear, ProSafe, D-Link, etc. Make sure you either have a certified network professional with you while setting up or a good tech support because trust me you’ll need them when you configure the system.
Software Firewall
Now that we know how Hardware Firewalls work, I’ll talk a bit Software Firewalls. To be honest, Software Firewalls do not need a whole lot of explanation because most of us are aware of it and are already using it. Like I said in the Hardware Firewall section if the user is not tech savvy and if they choose to allow a connection that has Malware behavior, it could ruin the entire network and put the company in risk with data security. That’s where software firewall comes into the picture, as here can we block both incoming and outgoing connections and setup trusted rules so these accidents can be avoided. Firewall vendors constantly research in this matter and see out updates as and when required, so the chances of your computer getting compromised are slim.
It’s a confusing job to pick a complete Internet Security solution that is just right for you. When you search in forums, you can see a flaming debate, where each member is defending their favorite ones. You’ll be lost in these debates ending up more confused than when you started. The rule is to set your priorities straight. Create a list of things you want. For example, do you want a free Firewall solution or paid one? What features you need in your Firewall, What additional features are required, like say Antispam, Web Protection, Malware scanner, Antivirus, etc. Do you want to go in for an Internet Security Suite? Once you decide, then compare the features. I for one use Windows Firewall. The the only drawback I find it has is that, by default, it allows all the outgoing connection. So I used an additional application called Windows Firewall Control – which we can set up to block all the outgoing connection and also the setup rules for the ones we want, with a simple click. They have both a free version and professional paid version, but the free version is more than enough. Windows Firewall Control and Windows Firewall Notifier are other two freeware you could check out.

You've heard that you need a firewall, but there are so many options. Software firewall? Hardware firewall? How do you know which is right for you?
First of all, hardware is something you can see, like the monitor you are looking at to read this text right now. Hardware refers to the hard physical elements—the computer, the keyboard, the circuitry inside your computer—anything you can see and touch. Hardware always includes some form of software. For example, your computer keyboard has a software program written into the circuitry that allows what you type to appear on the screen. But you don't have to purchase this software for your keyboard. It's already there.
Software, on the other hand, is a computer program that tells the hardware exactly what to do. This webpage, for example, was written in a computer language called HTML. HTML tells your monitor how to display the text you are reading now. Software is the name for the instructions that tell the computer what to do.
A hardware firewall is a small metal box filled with plug openings, or ports. You hook your computer network into the box then set it up on your computer, just as you would a new printer or other peripheral. Because it's not physically on your machine, a hardware firewall is less vulnerable than a software firewall.
Software firewalls give you the level of protection you need to keep safe from hackers and other unwanted intrusions because software is far easier for computer novices to customize. The features are suited to smaller home networks.
Some top software firewall packages also include antispam, antivirus, even anti-popup ad software. Some software firewalls include parental controls to manage what kinds of websites your children visit. Some packages allow you to block photos and specific text content that you do not want your children to view.
Hardware firewalls are best suited to businesses and large networks. IT professionals often have hardware firewalls in their homes. But for average consumers, software firewalls are best suited for home use.
