Mitigating Distributed Denial of Service (DDoS) attacks requires a combination of proactive measures and reactive strategies. Here are several mitigation techniques commonly employed to overcome DDoS attacks:

Traffic Filtering:

Implementing traffic filtering mechanisms helps identify and block malicious traffic, allowing only legitimate requests to reach the target system.

Employing firewalls, routers, or intrusion prevention systems (IPS) with access control lists (ACLs) to filter and drop suspicious traffic based on predefined rules or signatures.

Rate Limiting:

Rate limiting restricts the number of requests from a single source within a specific timeframe, reducing the impact of volumetric attacks.

Configuring network devices or application servers to enforce rate limits, preventing excessive requests from overwhelming system resources.

Anomaly Detection:

Anomaly detection involves monitoring network traffic and system behavior to identify unusual patterns or deviations from normal activity.

Utilizing intrusion detection systems (IDS) or security information and event management (SIEM) solutions to detect anomalies and trigger alerts for further investigation and mitigation.

Traffic Scrubbing:

Traffic scrubbing involves diverting incoming traffic through specialized mitigation platforms to identify and remove malicious traffic while allowing legitimate traffic to reach the target.

Employing cloud-based DDoS mitigation services or on-premises scrubbing appliances that analyze traffic patterns in real-time and filter out malicious traffic before it reaches the target infrastructure.
