To ensure secure and fully available cloud infrastructure, which solution helps observe and respond to security breaches?

1. XaaS

2. IDS

3. PaaS

4. IPS

The correct answer is: IDS

The best choice for observing and responding to security breaches in a secure and fully available cloud infrastructure is an Intrusion Detection System (IDS). An IDS monitors network traffic for suspicious activity and potential security breaches. It identifies, logs, and alerts administrators about these incidents, enabling rapid response and mitigation strategies. This proactive monitoring is crucial for maintaining the integrity and security of cloud environments, especially as they can be vulnerable to various attacks. In contrast, considering other options, XaaS (Anything as a Service) encompasses a broad range of cloud services but does not specifically focus on security observance or incident response. PaaS (Platform as a Service) provides a platform allowing developers to build, deploy, and manage applications but lacks the direct security monitoring capabilities that an IDS offers. IPS (Intrusion Prevention System) is primarily focused on actively blocking threats after detection but does not emphasize the observational aspect. While both IDS and IPS serve important functions in security, an IDS is specifically designed for the observational aspect, making it the more suitable choice for identifying and monitoring potential security breaches.
