Which of the following is a reporting feature of Alibaba Cloud's Security Center?

The reporting feature of Alibaba Cloud's Security Center focuses on providing insights and analyses regarding the security posture and events concerning an organization's resources. Security event reports are crucial as they summarize security incidents, provide details about potential vulnerabilities, identify threats, and suggest responses or mitigations. These reports enable organizations to understand their security landscape better and take informed actions to enhance their defenses.

While the other options may relate to security or operational aspects, they do not specifically align with the core function of the Security Center's reporting capabilities. Incident recovery status pertains to ongoing incident management rather than a report. Daily traffic summaries focus on network activity and do not reflect the security dimension. Cost management reports track expenses rather than security events. Therefore, security event reports distinctly represent the essential reporting feature of Alibaba Cloud's Security Center, helping users to monitor and manage their security effectively.
