AuthorizeSecurityGroupEgress

Adds one or more outbound rules to a security group. You can use this operation to specify outbound access permissions for a security group, allowing or denying instances in the security group from sending outbound traffic to other devices, which enables fine-grained network access control.

Operation description

Before you begin

Quantity limit: The total number of rules (including both inbound rules and outbound rules) across all security groups associated with a single network interface controller (NIC) cannot exceed 1,000. For more information, see Security group limits.
Priority settings: The priority (Priority) of outbound security group rules ranges from 1 to 100. A smaller number indicates a higher priority. If two security group rules have the same priority, the deny (drop) rule takes precedence.

Notes

If the specified security group rule already exists, the call succeeds but no rule is added.

How to determine a rule

The following parameters are required to determine an outbound rule:

Destination settings: Specify one of the following: DestCidrIp (IPv4 address), Ipv6DestCidrIp (IPv6 address), DestPrefixListId (prefix list ID), or DestGroupId (destination security group).
Destination port range: PortRange.
Protocol type: IpProtocol.
Access policy: Policy.

Note

Advanced security groups do not support authorization of other security groups for access. Custom security groups support a maximum of 20 authorized security groups.

Request examples

The following examples show how to add outbound rules with different destinations to a security group in the China (Hangzhou) region:

Add access permissions for a specified IP address range.

"RegionId":"ap-southeast-1",  // Specify the region.
"SecurityGroupId":"sg-bp17vs63txqxbds9***", // Specify the security group.
"Permissions":[
     {
       "DestCidrIp":"10.0.0.0/8", // Specify the destination IPv4 address.
       "PortRange":"-1/-1", // Specify the port range.
       "IpProtocol":"ICMP", // Specify the protocol type.
       "Policy":"Accept" // Specify the access policy.
     }
]

Add access permissions for another security group and a prefix list.

"RegionId":"ap-southeast-1",
"SecurityGroupId":"sg-bp17vs63txqxbds9***",
"Permissions":[
     {
       "DestGroupId":"sg-bp67acfmxazb4pi***", // Specify the destination security group.
       "PortRange":"22/22",
       "IpProtocol":"TCP",
       "Policy":"Drop"
     },{
       "DestPrefixListId":"pl-x1j1k5ykzqlixdcy****", // Specify the destination prefix list.
       "PortRange":"22/22",
       "IpProtocol":"TCP",
       "Policy":"Drop"
     }
]

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.
