For an organization experiencing DDoS attacks, what immediate measure can be crucial to mitigate financial losses?

• A. Upgrading server capacity
• B. Implementing rate limiting on server connections
• C. Increasing customer service staff
• D. Enhancing data encryption

Answer: (B)

Implementing rate limiting on server connections is a crucial immediate measure for organizations facing DDoS attacks. Rate limiting allows an organization to control the number of requests that a server will accept from a single IP address or user over a specific time period. This helps prevent overwhelming the server with excessive requests, which is the primary goal of a DDoS attack. By limiting the rate at which connections can be made, the organization can ensure that legitimate users can still access services, thereby mitigating the risk of substantial financial losses due to decreased availability and potential reputational damage.

In contrast, upgrading server capacity may provide a temporary buffer against larger attacks, but it does not address the fundamental issue of overwhelming traffic that is characteristic of a DDoS event. Increasing customer service staff is unlikely to be effective in the face of a DDoS attack, as the primary challenge is technical and operational rather than a matter of service availability or customer queries. Enhancing data encryption is excellent for securing data and communications but does not help with the immediate need to manage incoming traffic during a DDoS incident.
