Which method can a company use to ensure high availability during a security attack?

To maintain high availability during a security attack, automatic scaling is a highly effective method. This approach allows a company to automatically adjust its resources to meet increased demand or handle unexpected traffic spikes, which may occur during an attack, such as a Distributed Denial of Service (DDoS). By scaling resources up or down in real-time, the company can ensure that its services remain operational and accessible to legitimate users, even under stress from malicious activities.

Automatic scaling leverages the elasticity of cloud environments like AWS, enabling dynamic resource allocation based on predefined thresholds. This functionality is vital in maintaining performance and availability amidst security threats, ensuring business continuity.
