You can integrate Log Service with Security Center. After you integrate the two services, you can use Log Service to collect risk data from Security Center in real time. Then you can search, analyze, transform, and consume the data in Log Service. This way, you can monitor and handle potential risks and implement centralized management over your cloud resources. This topic describes the resources and limits for the analysis of Security Center logs.
- Dedicated projects and Logstores
After the log analysis feature is enabled in the Security Center console, a dedicated project named in the sas-log-Alibaba Cloud account ID-region name format and a Logstore named sas-log are automatically created.Note If you accidentally delete the dedicated Logstore, a message that indicates the sas-log Logstore does not exist is prompted. All log data in the Logstore is deleted. In this case, submit a ticket to restore the settings. After the settings are restored, you must re-enable the log analysis feature. The deleted data cannot be recovered.

- You can query and consume log data in the dedicated Logstore. You can also create alerts for the data. However, you can write only Security Center log data to the dedicated Logstore.
- You are charged for using the log analysis feature of Security Center. For more information, see Billing methods.
As required by the Cyber Security Law, logs are retained for at least 180 days. We recommend that you allocate a storage capacity of 30 GB to each server.
- You are not charged for the read/write traffic, indexing traffic, storage space, number of shards, and number of read/write times in the dedicated Logstore. However, you are charged for traffic from an external network, data transformation, and data shipping in the Logstore. For more information, see Log Service pricing.
