For greater protection against distributed denial-of-service (DDoS) attacks, you should consider using an anti-spoofing system. Statistics show that the average cost of a DDoS attack in the United States is nearly a quarter-million dollars. DDoS attacks are characterized by an excessive amount of network traffic. The attacker will flood your business’s network with traffic packets. Anti-spoofing, however, can help protect your business’s network from DDoS attacks.

What Is Anti-Spoofing?

Anti-spoofing is the process of identifying and blocking network traffic with a fake internet protocol (IP) address. All network traffic has an IP address. When another user attempts to access your business’s network, you’ll see his or her IP address.

Not all IP addresses are legitimate, though. IP addresses can be spoofed. A spoofed IP address is a fake IP address. They aren’t real IP addresses. Rather, spoofed IP addresses are fake IP addresses. They are typically used in DDoS attacks. The attacker may spoof thousands of IP addresses so that he or she can spam your business’s network. Anti-spoofing is a form of cybersecurity that’s designed to identify and block spoofed IP addresses.

How Anti-Spoofing Works

Anti-spoofing is essentially a traffic-filtering technology. It works by filtering traffic that contains a spoofed IP address.

You can configure a firewall for anti-spoofing. Many businesses use an application-level firewall to protect against DDoS attacks. With an application-level firewall, you can automatically filter traffic with a spoofed IP address.

Firewalls rely on rules to filter traffic. You can create rules to check the IP addresses of incoming traffic. If any traffic has a spoofed IP address, the firewall will block it.

Other DDoS Mitigation Tips

In addition to anti-spoofing, there are other safeguards you can implement to mitigate the risk of DDoS attacks. A content delivery network (CDN) is a useful DDoS mitigation tool. Even if your business’s main server is attacked, the CDN may keep your business’s network up and running.

You should also consider using rate limiting. Rate limiting is the process of controlling the speed at which users can send requests to your business’s network. DDoS attacks, as well as DoS attacks, often involve multiple requests from the same users. Rate limiting will allow you to slow down these requests so that they don’t jeopardize the integrity of your business’s network.

Always create backups of your business’s files. Backups won’t prevent your business from becoming the target of a DDoS attack. If the attack causes data loss, though, you can restore the lost data.
