How to prevent DDoS attacks: Everything you should know

For businesses, distributed denial-of-service (DDoS) attacks are particularly dangerous. And with Microsoft preventing “an average of 1,435 [DDoS] attacks per day” in 2022, it is clear that these attacks are unnervingly common. 

That is why it is essential to take proactive steps to prevent DDoS attacks from happening. This guide will unveil everything organizations need to know about DDoS attacks, along with the security measures that can help businesses shield themselves from them for stronger cybersecurity postures.

What are DDoS attacks?

Distributed denial-of-service attacks are a type of cyber-attack that aims to undermine the regular functioning of a network by flooding it with compromised traffic. The threat actor accomplishes this by using a network of infected devices—botnets—to target the victim’s IP address with requests. The sheer volume of requests overwhelms the network, causing it to crash. Since the tools that make up botnets (for example, Internet of Things devices) appear as valid traffic, it is difficult to detect and isolate them.

What types of DDoS attacks are there?

For distributed denial-of-service cyber threats, there are different types of attacks. They include:

  • Volumetric attacks: Uses up the available bandwidth between the Internet and the victim.
  • Protocol attacks: Takes advantage of vulnerabilities in Internet communication procedures. These types of attacks are designed for whole networks. Smurf DDoS and SYN floods are two examples of protocol attacks.
  • Application-layer attacks: A targeted disruption that focuses on individual applications rather than whole systems. Threat actors send a large volume of HTTP requests that prevent the server from responding.

Are DDoS attacks and DoS attacks different?

Despite their similarities, there are several differences between distributed denial-of-service attacks and denial-of-service (DoS) attacks. As DDoS attacks use multiple sources to generate traffic, they can be executed at faster rates compared to DoS attacks that come from one location. Generally speaking, DoS attacks are not as complex compared to DDoS threats as they use fewer resources.

How can DDoS attacks damage businesses?

Like with all entities in the cyber threat landscape, DDoS attacks can pose a significant threat to a business’s operations.

DDoS attacks can harm your business in the following ways:

  • Lost revenue: If a DDoS attack downs your network, it can slow your organization down, leading to less profit. And the longer the attack lasts, the more financial losses occur.
  • Damage to reputation: The longer your systems remain down, the more trust your customers may lose in your business.
  • Damaged cybersecurity posture: DDoS attacks can force companies to shift their attention and resources to deal with the immediate threat. Oftentimes, threat actors use DDoS to distract organizations while they carry out other attacks. This can make a network more vulnerable to cyber risks and undermine a business’s overall cybersecurity posture.

How can businesses detect a DDoS attack?

Since the traffic generated by a DDoS attack can look similar to legitimate traffic, detecting it in real time can be challenging.

However, there are some signs that indicate a distributed denial-of-denial service attack has occurred:
