How to Easily Harden Your Firewall

Your firewall isn’t a “set it and forget it” tool. In today’s cybersecurity landscape, hackers are actively looking to exploit even the smallest vulnerabilities. Fortunately, hardening your firewall is simpler than you might think.

Here are three actionable steps to strengthen your firewall security:

1. Block External Access

Many firewalls offer convenient remote management capabilities, allowing administrators to log in and manage them from anywhere using an IP address and credentials. But this convenience is also a risk—it’s a potential entry point for hackers.

What to do:

• Disable remote management options like HTTPS logins or web-based admin access.
• Restrict access to your firewall’s management console to local networks or trusted devices only.

By closing this front door, you eliminate one of the most common avenues hackers exploit.

2. Enforce Multi-Factor Authentication (MFA) on VPN

A stolen password is all it takes for a hacker to gain access to your Virtual Private Network (VPN). If MFA isn’t enforced, compromised credentials can lead to a significant breach.

What to do:

• Enable multi-factor authentication on all VPN connections.
• Use time-based one-time passwords (TOTP) or app-based authentication for stronger security.

MFA adds an extra layer of protection that stops hackers in their tracks, even if they have a valid password.

3. Mass-Block Known Threat Actors and Countries

Why wait for an attack when you can proactively block known bad actors? Many firewall tools allow you to blacklist entire countries or malicious IP addresses known for cyber threats.

What to do:

• Block traffic from high-risk countries like Russia, China, and North Korea.
• Implement blacklists of rogue IPs and update them regularly.

By proactively filtering traffic, you reduce the chances of malicious connections even reaching your network.
