What safeguards do you have in place to protect your business’s network from malicious traffic? Research shows that nearly two-thirds of all businesses have experienced one or more cyber attacks. It only takes a single cyber attack, of course, to compromise the data on your business’s network. Rather than waiting until a cyber attack occurs, you should take a proactive approach toward securing your business’s network.

MAC address filtering offers a simple and effective way to secure your business’s network. You don’t have to spend thousands of dollars on cybersecurity software. As long as your business’s network features a router or similar access point, you can enable MAC address filtering.

What Is MAC Address Filtering?

MAC address filtering is an access control solution that involves restricting network traffic based on MAC addresses. As the name suggests, it’s designed to filter network traffic based on their respective MAC address.

MAC addresses, of course, are assigned to network cards. Each network card has a unique MAC address. If a user wants to connect to your business’s network, his or her network card requires a MAC address. MAC address filtering is the process of allowing or blocking certain MAC addresses from accessing a network.

How MAC Address Filtering Protects Against Network Threats

You can protect your business’s network from distributed denial-of-service (DDoS) attacks by using MAC address filtering. DDoS is a common type of network threat. It involves a hacker spamming a network with requests from many different devices. Networks can only process so many requests at any given time. During a DDoS attack, the targeted network will be flooded to the point where it experiences performance problems.

To safeguard your business’s network from DDoS attacks, you should consider using MAC address filtering. This simple cybersecurity solution will allow you to whitelist or blacklist MAC addresses. Whitelisted MAC addresses will be allowed to access your business’s network. Blacklisted MAC addresses, on the other hand, will be blocked from accessing your business’s network.

MAC address filtering can keep bad traffic out of your business’s network. If you discover that malicious traffic is coming from a particular MAC address, you can block it. Alternatively, you can use MAC address filtering to only allow safe, approved MAC addresses to access your business’s network.

MAC Address Port Filtering Explained

Some routers and other access points support port-based MAC address filtering. Known as port security, it can protect your business’s network from DDoS attacks — just like standard MAC address filtering. The difference is that port security allows you to target MAC addresses by port.
