They have the same general mission, but they go about it in slightly different ways, giving them their own set of advantages:. At the same time, the protection of a software firewall also comes with limitations.
They have to be installed on every computer in the network. When it comes time to update your protection, if any of the units are not prepared to receive the update, they have to be updated manually. Since they don't have their own operating systems, software firewalls can also drain crucial computing power and memory, affecting user experience and network security. A hardware firewall acts as a gatekeeper and antivirus solution for your server. It sits directly behind the router and can be configured to analyze incoming traffic, filtering out specific threats as they come across the device.
A hardware firewall is a physical device much like a server that filters the traffic going to a computer. While a user would normally plug a network cable directly into a computer or server, with a hardware firewall, the cable is plugged into the firewall first. The firewall sits between the external network and the server, providing an antivirus solution and a hard barrier against intrusions.
Although the specific setup depends on how your network is configured, all firewalls operate in a similar fashion. Positioned between your network and the internet, they help protect your network from potential harm or from being used by bad actors to spread malicious data elsewhere.
One simple type of firewall is called a packet filter, which examines the data itself. Because the data comes with information regarding its source and location, the firewall uses this to determine whether or not the data poses a threat to the system, then runs the information through a list of permissions. If the data does not pass the permissions checklist, it is not allowed through. If, according to the permissions, the data is safe, it is allowed to pass.
Modern hardware firewalls can examine data in both directions. Similar to the mechanism for scrutinizing incoming traffic, the firewall applies a set of permissions to outgoing data as well. In this way, it can catch data embedded in the coding designed to use your computer to spread malicious code to other computers on the internet.
Many people wonder if their router can act as a firewall replacement. They reason that because many routers have protective capabilities, they provide an adequate solution.
In some cases, a router may provide the protection you need, such as:. If a router is used in conjunction with another firewall, it can provide an extra layer of protection. It also runs the packets through predefined key permissions to flag any suspicious packets and block access to the network. A hardware firewall relies on physical devices to provide information security and data filtering. Let us look at the advantages of this type of firewall.
As the name suggests, a software firewall is installed on computers as the second line of defense against potential threats. This is because any unauthorized access or malicious code it is trying to block has already bypassed the router or hardware firewall.
Whenever a program tries to access the network, the software firewall determines malicious or legitimate by checking it against a database. Depending on this information, the firewall either allows or blocks the transfer of data. This type of firewall can also be configured to check and block any suspicious outgoing requests. A software firewall is installed on individual devices like computers and phones to control better what the device can do. While a hardware firewall blocks traffic entering the network, firewall software blocks the traffic trying to enter the device.
This means such software can block users or devices from accessing individual components of the network and not just the network as a whole. For example, firewall software is a great way to restrict access to a printer on a network. Mac OS and Windows version 7 and later come with a built-in software firewall that blocks programs from accessing the internet based on the time of the day, user, and program trying to access the network.
However, such software generally lacks advanced features, so users supplement or replace them with after-market solutions. More advanced software firewalls usually offer better control over what access rights a user or device is permitted. As they are installed on a device, they can inspect all the traffic coming to the device and filter data based on a set of rules.
When comparing software firewall vs hardware firewall, a key difference is that while a hardware firewall can only block a domain or website, a software firewall can block content based on keywords. A software firewall relies only on a software application to serve as a cybersecurity tool. There are several advantages a software firewall offers over a hardware firewall.
Both types of firewall, hardware, and software, have their pros and cons when used for information protection. However, several factors decide the selection of the firewall for security within an organization. Below we compare hardware firewalls vs software firewalls by considering the distinguishing features of the two types:.
Deciding whether you should use a hardware firewall or a software firewall is often not easy, looking at the advantages of both these types of cybersecurity tools.
The right choice between the two depends on the needs and situation of the organization. Quite often, organizations need a combination of both.
Medium to large organizations with an extensive network of computers may find a hardware firewall more preferable for information security. However, hardware firewalls installed in a network configuration are exposed to some vulnerabilities. This is why it is better to install firewall software and hardware firewalls for a high level of security within the organization. However, industries like finance and healthcare will need both types of firewalls in a combination.
