Hardware vs. Software in Firewall Selection

Connecting your network to the Internet without a firewall is like to leaving your office door wide open while on vacation. Someone will almost certainly walk in and grab your belongings at some point. (Fortigate Firewall)

Many devices and software applications come with Fortigate Firewall, but when it comes to securing sensitive data, it’s best to know what you’re getting and what you may be receiving instead. Just as a closed front door deters burglars from ransacking your home, an effective firewall will protect your firm from attempts by hackers to steal valuable data. According to a recent survey by Forrester Research of Cambridge, Massachusetts, small and mid-size business owners are increasingly opting to install firewalls for this reason, with 44 percent expecting to acquire firewalls within the next 12 months. According to the report, the most significant factor for small and mid-size firms is straightforward management.

The good news is that there are only two types of firewalls to think about: hardware and software. Here’s how they operate and why they might or might not work for you.

Firewalls in hardware

Hardware firewalls are built into the router that connects a computer to the Internet. They usually employ packet filtering, which entails scanning packet headers to determine the source, origin, and destination addresses of incoming traffic, as well as whether the traffic is related to an outgoing connection, such as a website request. This data is compared to a set of user-defined rules to see if the packet should be sent or blocked. Check to verify if your wired or wireless router already has a hardware firewall configured. Most do.

A hardware firewall has the following benefits:

A single hardware firewall can secure your entire network, which is very useful for businesses with many PCs.
They have no impact on system performance or speed because they do not run on your PCs.
Businesses that employ a broadband Internet connection, such as DSL or cable modem, benefit from hardware firewalls.
Malicious software cannot readily disable a hardware firewall, as it does with software firewalls.
Installing a single hardware firewall to protect several PCs may end up being less expensive than licencing software firewalls on each PC in the business.

A hardware firewall has the following drawbacks:

Routers can be costly, costing several hundred dollars or more.
They may be more complex to set up, particularly for beginners.
Outgoing traffic from the local network is treated as secure by hardware firewalls, which might be dangerous if malware, such as a worm, infiltrates your network and seeks to connect to the Internet.

Firewall software

Individual machines have software firewalls installed. They intercept each network request to connect to the computer and determine whether or not the request is valid. Outgoing requests that are suspicious can be checked using software firewalls.

A software firewall has the following benefits:

Top-rated software firewalls are less than $50, making them a more cost-effective option for a small workplace with less than four computers.
Hardware routers are more difficult to set up. With a few clicks throughout the installation process, you may choose the amount of protection you want, and provide multiple security levels depending on the system or user. The greatest degree of protection may disable all cookies and JavaScript, preventing some Web pages from loading or displaying them incorrectly. This is especially true for private sites.
They’re adaptable. You can limit which applications are permitting to connect to the Internet, lowering the risk of malware connecting. A software firewall might be useful in the instance of an e-mail worm that develops its own e-mail server, such as the recent “MyDoom” worm, which might not be identified by a router due to its trusted origin.
You are free to take it with you. A software firewall secures the machine on which it is install, regardless of where it is connecting. This is a crucial feature for business travellers who travel with laptop computers.

A software firewall has the following drawbacks:

Software firewalls consume more system resources than hardware firewalls, such as memory and disc space, causing your computer to slow down.
You’ll have to buy a copy for each machine connected to the network, which adds up quickly.
Your IP address cannot be hidden using software firewalls. Instead, they monitor traffic to and from open ports and close unused ports.

A firewall is a mechanism that protects your computer from unauthorised users trying to access it via the network. A firewall can be hardware or software, and it’s usually set up to block all incoming traffic until the user explicitly allows it. If not correctly set, the Fortigate Firewall can be quite successful in preventing unwanted access, but it can also cause difficulties. To correctly set firewalls for your needs, you must first understand how they work. To get the most protection, experts recommend installing both types of firewalls.
