ModifySecurityGroupPolicy-阿里云帮助中心

Operation description

Advanced security groups do not support modifications to the intra-group connectivity policy. The default policy is internal isolation.
You can call DescribeSecurityGroupAttribute to query the current intra-group connectivity policy of a security group.
When the intra-group connectivity policy of a security group is set to intra-group connectivity, other custom access rules are ignored, and all instances in custom security group are connected over the internal network by default.
When the intra-group connectivity policy of a security group is set to internal isolation, all instances in custom security group are disconnected over the internal network by default if no other access rules are added. However, you can customize security group rules to change the internal network status. For example, you can call AuthorizeSecurityGroup to enable network connectivity between two ECS instances in custom security group.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
