Request Parameters Response Elements Errors Examples See Also

AuthorizeSecurityGroupIngress

Adds the specified inbound (ingress) rules to a security group.

An inbound rule permits instances to receive traffic from the specified IPv4 or IPv6 address range, the IP address ranges that are specified by a prefix list, or the instances that are associated with a destination security group. For more information, see Security group rules.

You must specify exactly one of the following sources: an IPv4 or IPv6 address range, a prefix list, or a security group. You must specify a protocol for each rule (for example, TCP). If the protocol is TCP or UDP, you must also specify a port or port range. If the protocol is ICMP or ICMPv6, you must also specify the ICMP/ICMPv6 type and code.

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

For examples of rules that you can add to security groups for specific access scenarios, see Security group rules for different use cases in the Amazon EC2 User Guide.

For more information about security group quotas, see Amazon VPC quotas in the Amazon VPC User Guide.

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.

Note

Amazon canonicalizes IPv4 and IPv6 CIDRs. For example, if you specify 100.68.0.18/18 for the CIDR block, Amazon canonicalizes the CIDR block to 100.68.0.0/18. Any subsequent DescribeSecurityGroups and DescribeSecurityGroupRules calls will return the canonicalized form of the CIDR block. Additionally, if you attempt to add another rule with the non-canonical form of the CIDR (such as 100.68.0.18/18) and there is already a rule for the canonicalized form of the CIDR block (such as 100.68.0.0/18), the API throws an duplicate rule error.

To specify an IPv6 address range, use IP permissions instead.

To specify multiple rules and descriptions for the rules, use IP permissions instead.

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

If the protocol is TCP or UDP, this is the start of the port range. If the protocol is ICMP, this is the ICMP type or -1 (all ICMP types).

To specify multiple rules and descriptions for the rules, use IP permissions instead.

Type: Integer

Required: No

GroupId

The ID of the security group.

Type: String

Required: No

GroupName

[Default VPC] The name of the security group. For security groups for a default VPC you can specify either the ID or the name of the security group. For security groups for a nondefault VPC, you must specify the ID of the security group.

Type: String

Required: No

IpPermissions.N

The permissions for the security group rules.

Type: Array of IpPermission objects

Required: No

IpProtocol

The IP protocol name (tcp, udp, icmp) or number (see Protocol Numbers). To specify all protocols, use -1.

To specify icmpv6, use IP permissions instead.

If you specify a protocol other than one of the supported values, traffic is allowed on all ports, regardless of any ports that you specify.

To specify multiple rules and descriptions for the rules, use IP permissions instead.

Type: String

Required: No

SourceSecurityGroupName

[Default VPC] The name of the source security group.

The rule grants full ICMP, UDP, and TCP access. To create a rule with a specific protocol and port range, specify a set of IP permissions instead.

Type: String

Required: No

SourceSecurityGroupOwnerId

The Amazon account ID for the source security group, if the source security group is in a different account.

The rule grants full ICMP, UDP, and TCP access. To create a rule with a specific protocol and port range, use IP permissions instead.

Type: String

Required: No

TagSpecification.N

The tags applied to the security group rule.

Type: Array of TagSpecification objects

Required: No

ToPort

If the protocol is TCP or UDP, this is the end of the port range. If the protocol is ICMP, this is the ICMP code or -1 (all ICMP codes). If the start port is -1 (all ICMP types), then the end port must be -1 (all ICMP codes).

To specify multiple rules and descriptions for the rules, use IP permissions instead.

Type: Integer

Required: No

Response Elements

The following elements are returned by the service.

requestId

The ID of the request.

Type: String

return

Returns true if the request succeeds; otherwise, returns an error.

Type: Boolean

securityGroupRuleSet

Information about the inbound (ingress) security group rules that were added.

Type: Array of SecurityGroupRule objects

Errors

For information about the errors that are common to all actions, see Common client error codes.

Examples

Example 1

This example request grants TCP port 80 access from the source group sg-2a2b3c4d to the security group sg-1a2b3c4d. The source security group must be in the same VPC or in a peer VPC (requires a VPC peering connection).
