Keep in mind that these systems require proper tuning and maintenance to function optimally. An incorrectly configured firewall can lead to unintended accessibility issues.

Rate Limiting and Throttling

Rate limiting is another crucial technique for defending against DDoS attacks. It restricts the number of requests a user can make to a server, effectively mitigating heavy traffic loads that typical attacks generate. This technique ensures that legitimate users can still access services while reducing the overall volume of requests processed.

Throttling can complement rate limiting by temporarily reducing the connection speed or request count for users who exceed set thresholds. This selective approach safeguards resources and ensures that other users are not affected. Both strategies should be adjusted with regard to normal traffic patterns. It may necessitate continuous monitoring and adjustment to thresholds to maintain a balance between accessibility and security.

DDoS Mitigation Services

DDoS mitigation services offer targeted protection against such attacks. These service providers maintain large networks with substantial bandwidth capacity, enabling them to absorb and filter out malicious traffic before it reaches a client's infrastructure. Employing these services can dramatically reduce the risk of downtime caused by a DDoS attack.
