Firewall vs. Antivirus: What's the Difference?

By: Stickley on Security & Millennium Corporate Credit Union

In today's interconnected world, cybersecurity is more important than ever. Credit unions of all sizes face the threat of cyberattacks, and the stakes are high. A successful attack can result in the loss of sensitive data, financial damage, and reputational harm. Fortunately, a variety of cybersecurity solutions are available to help credit unions protect themselves, such as robust firewalls and antivirus software. Investing in these solutions defends credit unions against a wide range of threats, such as malware, viruses, and SQL injections, while aligning with NCUA guidelines that urge federally insured credit unions to protect sensitive member records from high-risk breaches.

What is a Firewall?

A firewall filters traffic between two or more networks. It is used to protect an organization's internal network from external threats such as malware, hacking, and denial-of-service attacks. Firewalls can be implemented in a number of ways, including by using network address translation (NAT), application-level gateway (ALG), and stateful inspection.

What is Antivirus Software?

Antivirus software is designed to detect, prevent, and remove malicious code from computers and devices. These products are typically used to protect against computer viruses, which are malicious programs designed to replicate and spread across an entire network. However, antivirus software can also protect against other types of malware, including spyware, adware, and ransomware.

What is the Difference?

A firewall is responsible for monitoring traffic to and from your network. It blocks or allows traffic based on specific security rules set by your organization's IT department. A firewall can be implemented as hardware, software, or a combination of both. Antivirus software, on the other hand, is designed to detect and remove malware from your computer or prevent it from infecting it in the first place. Firewalls primarily prevent unauthorized access to your network, while antivirus software protects your computer from malicious software.

Both firewalls and antivirus software are important tools for keeping your computer and network safe, but they work in different ways. It is important to have both a firewall enabled and an antivirus installed on your computer, and to keep them up to date at all times. By working together, these two tools can provide comprehensive protection against a wide range of threats.
