Context
DDoS attacks disrupt the normal operation of services by exposing the target system to a large number of malicious traffic. Although firewalls can provide basic protection, they are usually limited in the face of large-scale attacks. Effective defense requires a combination of strategies and real-time traffic monitoring to enhance the system’s resilience and ensure continuous service availability. Also read: What is a firewall?

Analysis
DDoS attack is a type of cyber assault aimed at disrupting the normal functioning of a targeted server, service, or network by overwhelming it with a flood of internet traffic. In a DDoS attack, multiple compromised devices, often part of a botnet, are used to send a massive amount of data requests to the target, causing it to become slow, unresponsive, or completely inaccessible to legitimate users. DDoS attacks can be categorised based on the layers of the Open Systems Interconnection ( OSI ) model they target, such as the network layer (Layer 3), transport layer (Layer 4), or application layer (Layer 7). Infrastructure layer attacks (Layers 3 and 4) are usually large-scale and easier to detect, while application layer attacks (Layers 6 and 7) are more complex, often focusing on specific aspects of an application to disrupt its functionality. Protecting against DDoS attacks typically involves reducing the attack surface, scaling up resources, monitoring traffic, and deploying specialised defenses like firewalls and rate limiting.

Key Points
- A Distributed Denial of Service (DDoS) attack paralyses the target system through large amounts of network traffic, and firewalls can only provide limited protection, often requiring multiple layers of protection to effectively counter.
- Other defenses include content delivery networks (CDNs), load balancing, DDoS mitigation services, and traffic monitoring.
