What is the purpose of ensuring availability in a security posture?

1. To prevent unauthorized data access

2. To ensure services are available to authorized users

3. To maintain data integrity during transmission

4. To encrypt sensitive user information

The correct answer is: To ensure services are available to authorized users

Ensuring availability within a security posture is primarily focused on making sure that services and resources are accessible and operational for authorized users when needed. This means that even in the face of security incidents, such as attacks or system failures, the infrastructure must remain functional and accessible to those who have the right to use it. Enhanced availability contributes to business continuity, ensuring that critical applications and data remain available for users to perform their tasks, thus preventing disruption in operations. For example, if a web service is under a denial-of-service attack, measures to ensure availability would include implementing failover mechanisms or load balancing to maintain access for legitimate users. Other aspects like preventing unauthorized data access, maintaining data integrity, or encrypting sensitive information are essential components of an overall security posture, but they specifically relate to confidentiality and integrity rather than the availability aspect of systems and services.
