Today’s cyberattacks are often conducted on a large scale, attacking institutions and organizations that hold a significant amount of sensitive user data. One such type of attack are leveraged against schools, colleges, and universities, many of which do not have the resources available to protect against them. Let’s go over what these types of student records do for hackers and... Read More

Chances are, you’ve at least heard the term firewall before. A fairly recent term, it was first used as a computing term in the 1983 movie WarGames before it was ever introduced into mainstream computing. Thanks Matthew Broderick! Since then, the term has expanded and grown to include a variety of approaches. Let’s dig into what a firewall does, as far as each of the various types are concerned.
First, What Does a Firewall Do?
Named for the protective measures that are built into the structure of connected homes and multiple-resident buildings, a firewall on your computer serves much of the same purpose as its namesake. Just as the residential firewall helps to keep a fire from spreading, a computer firewall monitors your network traffic to prevent unauthorized connections from being made. As a result, a properly configured firewall is an essential component of a smart business’ cybersecurity strategy.
Let’s explore some of the different types of firewalls out there, and what they do.
A virtual firewall is one that is hosted in the cloud, meant to protect an environment that is hosted in the cloud or within a virtual machine. As such, it can be customized to the needs that the user has of it, whether they require a specific application to be protected or an entire cloud environment.
Stateful Inspection Firewall
Most modern infrastructures feature this version of a firewall which performs a function known as dynamic packet filtering. Basically, for traffic to pass through the firewall, it needs to be the correct “state.”
Unified Threat Management Firewall
With a UTM firewall, the firewall’s capabilities are augmented by the inclusion of antivirus software. Intentionally easy to use, UTM firewalls can protect a business’ email inbox or defend a remote worker from threats, along with many other necessary safeguards.
Is a Firewall a Requirement for Your Business’ Cybersecurity?
In a word: yes… with the caveat that real cybersecurity will require more than just a firewall to be effective. While a firewall is an important piece of your cybersecurity strategy, it is just that: a piece. Truly effective cybersecurity needs additional safeguards in place.
