What Are DDoS Attacks?
Distributed Denial of Service (DDoS) attacks are a form of cyber attack designed to make a service, network, or application unavailable to legitimate users. This type of attack uses a large number of compromised devices to overload a target system's resources, causing slowdowns or complete shutdowns.

How DDoS Attacks Work
A DDoS attack is based on the generation of an extraordinarily high volume of traffic to a target system. This traffic is generated by a network of compromised devices, called a botnet. Devices within a botnet can include computers, smartphones, routers, and even IoT (Internet of Things) devices such as security cameras or smart appliances. These devices are infected with malware that makes them controllable by a remote attacker.
DDoS attacks can be divided into three main categories:
- Network-level attacks (Volumetric): These aim to saturate the target's bandwidth by sending a huge volume of data packets.
- Application-level attacks: These target specific services such as web servers, sending legitimate requests but in such quantities that they overload the system's resources.
- Protocol-level attacks: These exploit vulnerabilities in communication protocols, such as TCP/IP, to exhaust network or processing resources.
Why DDoS Attacks Are Dangerous
DDoS attacks can have serious consequences, including:
- Service disruption: Organizations that rely on online systems can suffer significant damage from extended downtime.
- Reputational damage: An unavailable service can undermine user trust and damage the company’s image.
- Financial loss: Downtime can result in lost sales, customers, and productivity.
How to Defend Yourself from a DDoS Attack
Preventing and mitigating DDoS attacks requires a multi-layered approach. Some of the most common strategies include:
- Using DDoS mitigation services: These services are designed to identify and filter malicious traffic before it reaches the target system.
- Using load balancing solutions: Distributing traffic across multiple servers reduces the risk of overload.
- Monitoring traffic: Continuous analysis of network traffic helps detect anomalies that may indicate an attack in progress.
- Securing your network: Using firewalls, intrusion prevention systems (IPS), and secure network configurations helps reduce the attack surface.
Conclusion
DDoS attacks are a growing threat in the cybersecurity landscape. Understanding how they work and taking preventative measures is essential to protecting systems and ensuring business continuity. As technologies evolve, attacker tactics also become more sophisticated, making a proactive approach to security critical.
