What does availability in security posture safeguard against?

1. Data being stolen

2. Loss of access during failures

3. Unauthorized data modification

4. Data loss due to natural disasters

The correct answer is: Loss of access during failures

Availability in the context of security posture primarily focuses on ensuring that systems, services, and data remain accessible and operational when needed. This involves protecting against various types of failures, whether they are due to hardware malfunctions, software bugs, network issues, or any other event that might disrupt access to resources. By ensuring high availability, organizations can safeguard users from experiencing loss of access during these failures, thereby maintaining business continuity and operational effectiveness. Upholding availability also generally involves implementing redundancy, failover strategies, and robust system architecture to mitigate the impact of unexpected events. Although the other options touch on important aspects of security—such as preventing data theft, unauthorized modifications, and losses due to disasters—these aspects fall more under the categories of confidentiality and integrity rather than direct availability concerns. Therefore, the emphasis on maintaining service access during failures clearly aligns with the concept of availability in security posture.
