Distributed Denial of Service (DDoS) attacks have become more and more frequent. They are growing in size, causing tremendous financial losses for organizations globally. Every minute of downtime costs thousands of dollars. The damage varies depending on the organization and its environment.
According to Gartner, downtime causes an organization to lose, on average, $300,000 per hour. Yet, DDoS attacks can last for hours as they become much more elaborate and thus difficult to prevent and solve. They might even have several vectors and flexible attack strategies that change in the process.
What Is a DDoS Attack?
A DDoS attack is a denial-of-service attack that causes the overflow of traffic. It produces an excessive number of requests so that a server or network can no longer function. Attackers use technologies like AI and machine learning, making their actions increasingly dangerous.
DDoS attacks are carried out with the help of large networks of computers and other devices. They can either be compromised or just tricked into being a part of the attack. The collection of these devices creates a botnet, which attackers control remotely.
DDoS attacks are used to make people frustrated and confused. They happen due to a number of reasons. Attackers might be interested in monetary gains or have ideological motives. A lot of DDoS attacks also have a tactical nature and function as part of a larger strategy.

DDoS attacks can be of different types. Each of them has a specific goal and target.
- Application layer attacks aim at Layer 7 of a network connection, which is a human-computer interaction layer. They flood the server and prevent normal content delivery. This type of DDoS attack is one of the hardest to differentiate from real traffic.
- Volumetric attacks are the most common and simple. They target Layer 3 with the goal to consume all bandwidth. It functions as a traffic jam, preventing the system from responding to legitimate requests in time. Volumetric attacks can last hours and days or, on the contrary, be very quick but still damaging.
- Protocol attacks exhaust the resources of a server. They target the transport and network layers of a network connection. A protocol attack starts a TCP/IP connection, but its final stage never happens. This consumes all resources of the target server, making it unable to respond to real requests.
With the rapid development of technology, DDoS attacks also become more sophisticated as they get new tools and methods.

One needs to stay aware of the ways to prevent a DDoS attack or deal with it in case of a cybersecurity threat.
How to Prevent DDoS Attacks
Here are eight steps that will help you keep your system safe from DDoS attacks:
- Monitor your network. To avoid DDoS attacks, you need to monitor your network constantly. It will help you to spot any abnormal activity and respond to a threat immediately. Thus, it is worth implementing technology that will keep you informed about the state of your network here and now.
- Train staff. People need to be aware of the warning signs of DDoS attacks and know how to act. Slow or unavailable service, unexpected increase in traffic, numerous requests coming from a specific IP address alongside other suspicious incidents signalize a DDoS attack. It is crucial for the staff to respond timely and minimize the consequences.
- Take care of security infrastructure. DDoS attacks evolve and become more difficult to deal with. That is why it is important to keep your network up to date in terms of security. Having an outdated system is a weak spot that puts you at risk.
- Set traffic thresholds. Although it is not a silver bullet, traffic limits can help you avoid DDoS attacks or at least buy you some time to fix the problem. Security measures like geo-blocking, blacklisting of suspicious IP addresses, and setting lower ICMP and UDP flood drop thresholds might be of use when dealing with DDoS attacks.
- Keep a DDoS attack mitigation plan ready. Any network can become a target for a DDoS attack. It means that you should always be ready to deal with this cyber threat and have a detailed response plan prepared. It might include the tools that are to be used, staff responsible for dealing with a DDoS attack, basic rules, and communication strategy.
- Provide sufficient bandwidth. As DDoS attacks flood a server with traffic, one of the ways to deal with the problem is to extend its capacity. This way, the server will be able to handle even abnormal amounts of traffic and give you more time to handle the problem.
- Consider cloud-based solutions to deal with DDoS attacks. Using the cloud is one of the strategies to minimize DDoS attack risks. It is able to provide more bandwidth that will not be consumed fast. Cloud-based solutions allow dealing with dangerous traffic and protect your network.
- Examine your network for weaknesses. To keep your network safe from DDoS attacks, you need to fix its weak points. Perform regular examinations to find vulnerabilities that can compromise the safety of a network.
The online world is full of cybersecurity threats, DDoS attacks being only one of them. They get more elaborate and harder to detect every day. Thus, it is crucial to have preventive measures and a response plan in place to protect your data and operations from digital criminals.
