Firewalls are integral to computer networking and security. Computer firewalls are hardware and software systems designed to prevent unauthorized network access while permitting users to communicate outside the network. However, a new IT term — the "human firewall" — has emerged recently, and many people are confused about its meaning. If you're unfamiliar with the phrase, below is an introduction to the subject.

What Is the Human Firewall?

The human firewall consists of workers who have been educated to help them deal with cyberattacks. It involves IT professionals, as well as traditional workers who've been trained to identify subtle or psychological tricks.

For instance, the human firewall includes employees who question the legitimacy of an email from an unknown source or an advertisement that sounds too good to be true. The more wary and skeptical these workers are, the less likely they are to contribute to data leaks, establishing a strong human firewall.

Why Is It Necessary?

Human error is a weak point of any computer networking security system. For instance, failure to abide by password protocols and improperly providing secure information are two key reasons for network breaches. These cost businesses millions of dollars in wasted time, damaged files, and lost customer trust each year. 

Technological firewalls are static, while the ingenuity of hackers and malware developers is ongoing. When you have a strong human firewall, your business is better prepared to face online threats that could otherwise prove catastrophic. 

How Can You Improve Its Effectiveness?

First, educate your employees through regular training. Set up monthly or quarterly meetings to spread awareness of new types of phishing or social engineering attacks. Explain the types of behaviors that are and aren't allowed, and let workers know the value of the data they control. 

To illustrate how this training might look in real time, walk them through responding to certain situations. For example, show them a common phishing email and have them point out the red flags.
