AuthorizeSecurityGroupIngress

Adds the specified ingress rules to a security group.

An inbound rule permits instances to receive traffic from the specified IPv4 or IPv6 CIDR address ranges, or from the instances associated with the specified destination security groups.

You specify a protocol for each rule (for example, TCP). For TCP and UDP, you must also specify the destination port or port range. For ICMP/ICMPv6, you must also specify the ICMP/ICMPv6 type and code. You can use -1 to mean all types or all codes.

Rule changes are propagated to instances within the security group as quickly as possible. However, a small delay might occur.

For more information about VPC security group limits, see Amazon VPC Limits.

Request Parameters

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.

CidrIp

The IPv4 address range, in CIDR format. You can't specify this parameter when specifying a source security group. To specify an IPv6 address range, use a set of IP permissions.

Alternatively, use a set of IP permissions to specify multiple rules and a description for the rule.

Type: String

Required: No

DryRun

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

Type: Boolean

Required: No

FromPort

The start of port range for the TCP and UDP protocols, or an ICMP type number. For the ICMP type number, use -1 to specify all types. If you specify all ICMP types, you must specify all codes.

Alternatively, use a set of IP permissions to specify multiple rules and a description for the rule.

Type: Integer

Required: No

GroupId

The ID of the security group. You must specify either the security group ID or the security group name in the request. For security groups in a nondefault VPC, you must specify the security group ID.

Type: String

Required: No

GroupName

[EC2-Classic, default VPC] The name of the security group. You must specify either the security group ID or the security group name in the request.

Type: String

Required: No

IpPermissions.N

The sets of IP permissions.

Type: Array of IpPermission objects

Required: No

IpProtocol

The IP protocol name (tcp, udp, icmp) or number (see Protocol Numbers). To specify icmpv6, use a set of IP permissions.

[VPC only] Use -1 to specify all protocols. If you specify -1 or a protocol other than tcp, udp, or icmp, traffic on all ports is allowed, regardless of any ports you specify.

Alternatively, use a set of IP permissions to specify multiple rules and a description for the rule.

Type: String

Required: No

SourceSecurityGroupName

[EC2-Classic, default VPC] The name of the source security group. You can't specify this parameter in combination with the following parameters: the CIDR IP address range, the start of the port range, the IP protocol, and the end of the port range. Creates rules that grant full ICMP, UDP, and TCP access. To create a rule with a specific IP protocol and port range, use a set of IP permissions instead. For EC2-VPC, the source security group must be in the same VPC.

Type: String

Required: No

SourceSecurityGroupOwnerId

[nondefault VPC] The AWS account ID for the source security group, if the source security group is in a different account. You can't specify this parameter in combination with the following parameters: the CIDR IP address range, the IP protocol, the start of the port range, and the end of the port range. Creates rules that grant full ICMP, UDP, and TCP access. To create a rule with a specific IP protocol and port range, use a set of IP permissions instead.

Type: String

Required: No

ToPort

The end of port range for the TCP and UDP protocols, or an ICMP code number. For the ICMP code number, use -1 to specify all codes. If you specify all ICMP types, you must specify all codes.

Alternatively, use a set of IP permissions to specify multiple rules and a description for the rule.

Type: Integer

Required: No

Response Elements

The following elements are returned by the service.

requestId

The ID of the request.

Type: String

return

Is true if the request succeeds, and an error otherwise.

Type: Boolean

Errors

For information about the errors that are common to all actions, see Common Client Errors.

Examples

Example 1

[EC2-Classic] This example request grants TCP port 80 access from the 192.0.2.0/24 and 198.51.100.0/24 IPv4 address ranges to the security group in EC2-Classic named websrv.

Sample Request

https://ec2.amazonaws.com/?Action=AuthorizeSecurityGroupIngress
&GroupName=websrv
&IpPermissions.1.IpProtocol=tcp
&IpPermissions.1.FromPort=80
&IpPermissions.1.ToPort=80
&IpPermissions.1.IpRanges.1.CidrIp=192.0.2.0/24
&IpPermissions.1.IpRanges.2.CidrIp=198.51.100.0/24
&AUTHPARAMS

Example 2

[EC2-Classic, default VPC] This example request grants full ICMP, UDP, and TCP access from a source group called webserver1 (in AWS account 123456789012) to a security group in your account with the ID sg-1a2b3c4d. For EC2-VPC, the group owner ID parameter is not required, and the source security group must be in the same VPC. For an example of granting access to specific protocols and ports, see example 3.

Sample Request

https://ec2.amazonaws.com/?Action=AuthorizeSecurityGroupIngress
&GroupId=sg-1a2b3c4d
&SourceSecurityGroupOwnerId=123456789012
&SourceSecurityGroupName=webserver1
&AUTHPARAMS

Example 3

[EC2-Classic, default VPC] This example request grants TCP port 80 access from the source group named OtherAccountGroup (in AWS account 123456789012) to the security group named websrv. For EC2-VPC, the user ID parameter is not required, and the source security group must be in the same VPC.

Sample Request

https://ec2.amazonaws.com/?Action=AuthorizeSecurityGroupIngress
&GroupName=websrv
&IpPermissions.1.IpProtocol=tcp
&IpPermissions.1.FromPort=80
&IpPermissions.1.ToPort=80

&IpPermissions.1.Groups.1.UserId=123456789012
&AUTHPARAMS

Example 4

[EC2-VPC] This example request grants TCP port 80 access from the source group sg-2a2b3c4d to the security group sg-1a2b3c4d. In EC2-VPC, you must use the security group IDs in a request, not the security group names. The source security group must be in the same VPC or in a peer VPC (requires a VPC peering connection).
