Which solution would help a company maintain cloud infrastructure security while ensuring availability?

Choosing an Intrusion Detection System (IDS) as a solution for maintaining cloud infrastructure security while ensuring availability is appropriate due to the role IDS plays in monitoring network traffic for suspicious activity. An IDS can help identify potential security breaches or malicious activities, thus enabling organizations to take timely actions to mitigate threats, thereby preserving the integrity and availability of cloud services.

By continuously monitoring the environment and providing alerts on any potential incidents, an IDS supports a proactive security posture. This aligns well with the need for maintaining availability, as it can help prevent downtime caused by security breaches. Moreover, the alerts generated by an IDS can facilitate a swift response from security teams, reducing the time it takes to address threats before they escalate into severe issues that might affect service availability.

In contrast, other solutions, while valuable in their own right, do not directly fulfill the twin goals of maintaining security and ensuring availability in the same manner. Some may focus only on security aspects without addressing issues related to availability or they may complement security measures but do not provide the monitoring and identification capabilities that are vital for immediate responsiveness to potential threats.
