A distributed denial of service (DDoS) assault might bring your company to a complete halt, resulting in operational instability and downtime. There were nearly 6 million DDoS attacks in the third quarter of 2024 alone. But why are these attacks so tricky to deal with? Understanding how to stop a DDoS attack and the challenges that come with it is the first step to protecting your systems.
To understand the difficulty of preventing these attacks, let’s break down the difference between a DoS and a DDoS attack.
A single source overloads a server or network with traffic in a DoS (Denial of Service) attack, causing it to lag or crash. Multiple sources are used in a DDoS (Distributed Denial of Service) attack—often hacked devices grouped into a botnet—to overwhelm the target. Since the attack traffic comes from many places, it’s much harder to trace and block effectively. The Ponemon Institute reports that 45% of small businesses experienced a DDoS attack in the past year, with 70% reporting significant downtime as a result.
DDoS attacks are hard to prevent for the following reasons:
DDoS attacks are designed to drown servers in an enormous amount of traffic. Attackers often use botnets—large networks of infected devices spanning the globe—to send this traffic. These botnets can involve hundreds of thousands or even millions of compromised devices, all acting simultaneously to overload a system.
Even with well-prepared infrastructure, the sheer scale of such an attack can exceed what most servers can manage. To stop a DDoS attack, businesses need tools that can manage traffic spikes without blocking legitimate users, a challenging task that requires constant vigilance.
One of the biggest challenges in DDoS attack prevention is distinguishing between normal and malicious traffic.
Filtering out harmful requests without mistakenly blocking genuine users requires sophisticated monitoring systems and manual oversight. This balancing act is critical for businesses trying to figure out how to stop a DDoS attack without affecting user experience.
Attackers constantly update their strategies. For example, they might switch from overwhelming your bandwidth to targeting specific vulnerabilities in your applications. This constant evolution makes DDoS attack prevention a moving target.
DDoS attacks often rely on botnets with devices distributed worldwide. These attacks can originate from compromised computers, IoT devices, or servers in different countries, making it nearly impossible to block traffic at its source. The global nature of these attacks also complicates coordination between internet service providers (ISPs) and security teams.
Blocking traffic from entire regions may help reduce the impact but risks cutting off legitimate users as well. Addressing this challenge is a significant part of understanding how to stop a DDoS attack while maintaining service availability for real customers.
Big companies may have the resources to handle these attacks, but smaller businesses often don’t. Without advanced tools or teams to monitor their systems, they’re more vulnerable to the damage caused by DDoS attacks.
While DDoS attacks are challenging to prevent entirely, businesses can take measures to reduce their risk and mitigate the impact of an attack.
A WAF can help filter out malicious traffic before it reaches your server, providing a critical layer of defense. WAFs can detect unusual patterns and block requests that appear to be part of a larger DDoS attack.
Rate restriction limits how many requests from a single IP address a server will accept in a given amount of time. While it won’t stop distributed attacks, it can slow them down and minimize their impact.
Managed IT providers specialize in handling complex security challenges. They offer tools and expertise tailored to your organization’s needs, ensuring your systems are monitored and protected around the clock. Learn more about IT Managed Services to see how they can strengthen your defenses.
Using a distributed network of servers can help absorb the impact of a DDoS attack. By distributing incoming traffic among several servers, load balancers and content delivery networks (CDNs) make it more difficult for hackers to take down your system.
Awareness is a powerful tool. Educate your employees about DDoS attacks and cybersecurity best practices, so they understand the importance of early detection and response.
The primary difference between a DoS and a DDoS attack lies in the source of the traffic. A DDoS attack is more difficult to track down and stop since it spreads over several devices, whereas a DoS attack comes from a single source.
DDoS attacks are more sophisticated and often larger in scale, which is why organizations must adopt advanced tools and strategies to prevent them.
The impact of a DDoS attack can be devastating for businesses. It’s not just about downtime—these attacks can harm your reputation, lead to financial losses, and erode customer trust.
Proactive DDoS attack prevention measures, such as monitoring traffic patterns and using tools like WAFs, are essential to minimize risks. Partnering with a trusted provider, like Imagine IT, can also provide the expertise and resources needed to understand how to stop a DDoS attack.
