Security Center:[Notice] Log dictionary upgrade to V2.0

Last Updated:Jun 04, 2026

Dear Alibaba Cloud users,

Starting August 1, 2024, Security Center upgrades log dictionaries from V1.0 to V2.0. Log dictionaries define the fields collected and stored by the log analysis feature. V2.0 uses unified field names across Alibaba Cloud security products such as Security Center and Cloud Firewall, enabling cross-product log queries.

Differences between V1.0 and V2.0 log dictionaries

  • V1.0 log dictionaries are supported by the log analysis feature until August 1, 2024. For more information, see Log types and log fields of the v1.0 log dictionaries.

  • On August 1, 2024, Security Center releases V2.0 log dictionaries. V2.0 adds new log fields and renames some existing fields (field meanings remain unchanged), and supports log collection across multiple Alibaba Cloud security services. For supported fields and descriptions, see Log categories and fields.

The following lists the differences between V1.0 and V2.0 log dictionaries. Unlisted fields remain the same in both versions.

Automatic upgrade schedule

  • Starting August 1, 2024, V2.0 log dictionaries are automatically applied when you create Logstores by purchasing the Security Center log analysis feature.

  • For Logstores created before August 1, 2024, Security Center plans to automatically use V2.0 log dictionaries to record the fields of logs that are delivered later than October 30, 2024. Before October 30, 2024, you can continue to use V1.0 log dictionaries or manually upgrade the dictionaries to V2.0. The upgrade does not affect stored data or historical data integrity and availability.

If you encounter issues or require assistance during the upgrade, submit a ticket.

Upgrade impact

  • If you have not purchased the log analysis feature, this upgrade does not affect you.

  • If you purchased the log analysis feature before August 1, 2024, and consume logs or use custom alerts in the following scenarios, take action accordingly. You can manually upgrade log dictionaries to V2.0 when you use applications that consume log analysis data.

Note

If you cannot complete the secondary development before October 30, 2024, go to the Security Center console to request a 3-month extension. This way, the system automatically upgrades log dictionaries on January 30, 2025. Complete secondary development and manually upgrade to V2.0 before January 30, 2025.

Scenario

Solution

Query data in Simple Log Service

After the upgrade, use V2.0 field names in your queries.

Deliver Simple Log Service data to external databases for association analysis

  1. Modify the field mappings between the data stored in Simple Log Service ( SLS) and other databases . For more information, see Manage a data shipping job.

    Add the mappings between the modified field name and the newly added field to ensure that logs using dictionaries V2.0 can be delivered and the delivered data stored in V1.0 remains unaffected.

  2. Manually upgrade log dictionaries to V2.0. For more information, see Manually upgrade log dictionaries to V2.0.

  3. Verify that log delivery tasks complete successfully and the delivered data meets expectations.

Configure custom alert rules based on Simple Log Service log fields

  1. You must modify custom alert rules before October 30, 2024 to allow the rules to take effect after V2.0 log dictionaries are applied. For more information about how to modify an alert rule, see Manage alert rules.

  2. Manually upgrade log dictionaries to V2.0. For more information, see Manually upgrade log dictionaries to V2.0.

Deliver Simple Log Service data to external databases for secondary development and reporting

  1. Complete secondary development based on V2.0 log dictionaries before October 30, 2024.

  2. Manually upgrade log dictionaries to V2.0. For specific operations, see Manually upgrade log dictionaries to V2.0.

  3. Check whether the logs are delivered and whether the data delivered to the database meets expectations.

Manually upgrade log dictionaries to V2.0

  1. Log on to the Security Center console. In the top navigation bar, select the region of the asset that you want to manage. You can select China or Outside China.

  2. In the left-side navigation pane, choose Risk Governance > Log Analysis.

  3. In the upper-right corner of the Log Analysis page, move the pointer over Dictionary Version: V1.0 and click Upgrade Now.

  4. In the Upgrade Notes message, click Upgrade Now.
