The lessons learned phase of an incident response process involves reviewing the incident and generating reports. This phase helps identify what went well, what needs improvement, and what changes should be made to prevent future incidents. Documentation and reporting are essential parts of this phase to ensure that the findings are recorded and used for future planning.
* Recovery focuses on restoring services and normal operations.
* Preparation involves creating plans and policies for potential incidents, not reporting.
* Containment deals with isolating and mitigating the effects of the incident, not generating reports.

A jump server restricts and controls administrative access to the database system, reducing the attack surface. A host-based firewall limits network connections directly to the database server, preventing unauthorized access and hardening the system.

A self-signed certificate is created and signed by the issuing organization itself rather than by an external Certificate Authority, making it an internally generated certificate.

Deploying a load balancer in the company's cloud environment primarily fulfills the fundamental security requirement of availability. A load balancer distributes incoming network traffic across multiple servers, ensuring that no single server becomes overwhelmed and that the service remains available even if some servers fail.
Availability: Ensures that services and resources are accessible when needed, which is directly supported by load balancing.
Privacy: Protects personal and sensitive information from unauthorized access but is not directly related to load balancing.
Integrity: Ensures that data is accurate and has not been tampered with, but load balancing is not primarily focused on data integrity.
Confidentiality: Ensures that information is accessible only to authorized individuals, which is not the primary concern of load balancing.
