How does MaxCompute ensure data security?
MaxCompute provides multiple measures to ensure data security:
Unauthorized users cannot access a MaxCompute project. Only the project owner or a project administrator can grant access.
MaxCompute provides multiple authorization methods to ensure that only authorized users can access a project.
The sandboxed container in MaxCompute effectively prevents malicious operations. For more information, see Java sandbox.
MaxCompute uses an AccessKey ID and an AccessKey secret to authenticate users. If an information leak occurs, you can quickly disable the compromised AccessKey ID and AccessKey secret. This does not affect other AccessKey IDs or AccessKey secrets.
If a critical security risk occurs, you can run the
set ProjectProtection=true;command to enable the data protection mechanism. This prevents users from exporting data and stops potential data breaches.
Is data in MaxCompute reliable?
MaxCompute ensures data reliability with a three-replica storage pattern.
If you specify a lifecycle for a table, MaxCompute automatically deletes the table when the deletion rule is met. If you do not specify a lifecycle, the table is retained permanently by default.
Do VPC IP address whitelists support CIDR blocks?
Yes, they do. For more information, see Manage IP address whitelists.

What do I do if I cannot export MaxCompute data to MySQL due to the project data protection mechanism?
The project owner or a project administrator can run the set projectProtection=false; command to disable the data protection mechanism, or configure an exception policy to allow data exporting. For more information about data protection, see Data protection mechanism.
How can I recover a deleted table?
You can use the backup and recovery feature of MaxCompute to recover table data. For more information about backup and recovery, see Backup and recovery.
