B: Geographic distribution of critical data and services will ensure that multiple sites are available to restore data and services in the event of an APT attack. This will also reduce the impact of DDoS attacks by ensuring that traffic is spread across multiple sites. C: Hardened and verified container usage can help to isolate services from one another and protect them from APT attacks. Containerization can provide a secure and scalable platform for deploying services, which can be reconstituted quickly from a known-good state. H: Implementation and configuration of a SOAR platform will automate the process of responding to and mitigating APT attacks. The SOAR platform will allow the organization to create a set of automated actions that can be executed in response to security events, reducing the human operator demands.
