authorize-security-group-ingress

Note

To specify multiple rules in a single command use the --ip-permissions option

Description

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 .

--dry-run | --no-dry-run (boolean)

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 .

--protocol (string)

The IP protocol: tcp | udp | icmp

(VPC only) Use all to specify all protocols.

If this argument is provided without also providing the port argument, then it will be applied to all ports for the specified protocol.

--port (string)

For TCP or UDP: The range of ports to allow. A single integer or a range (min-max ).

For ICMP: A single integer or a range (type-code ) representing the ICMP type number and the ICMP code number respectively. A value of -1 indicates all ICMP codes for all ICMP types. A value of -1 just for type indicates all ICMP codes for the specified ICMP type.

--cidr (string)

The CIDR IP range.

--source-group (string)

The name or ID of the source security group.

--group-owner (string)

The AWS account ID that owns the source security group. Cannot be used when specifying a CIDR IP address.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples

[EC2-Classic] To add a rule that allows inbound SSH traffic

The following example enables inbound traffic on TCP port 22 (SSH). If the command succeeds, no output is returned.

aws ec2 authorize-security-group-ingress \\
    --group-name MySecurityGroup \
    --protocol tcp \
    --port 22 \
    --cidr 203.0.113.0/24

This command produces no output.

[EC2-Classic] To add a rule that allows inbound HTTP traffic from a security group in another account

The following example enables inbound traffic on TCP port 80 from a source security group (otheraccountgroup) in a different AWS account (123456789012). Incoming traffic is allowed based on the private IP addresses of instances that are associated with the source security group (not the public IP or Elastic IP addresses).

aws ec2 authorize-security-group-ingress \
    --group-name MySecurityGroup \
    --protocol tcp \
    --port 80 \
    --source-group otheraccountgroup \
    --group-owner 123456789012

This command produces no output.

[EC2-Classic] To add a rule that allows inbound HTTPS traffic from an ELB

The following example enables inbound traffic on TCP port 443 from an ELB.

This command produces no output.

[EC2-VPC] To add a rule that allows inbound HTTP traffic from another security group

The following example enables inbound access on TCP port 80 from the source security group sg-1a2b3c4d. Note that for EC2-VPC, the source group must be in the same VPC or in a peer VPC (requires a VPC peering connection). Incoming traffic is allowed based on the private IP addresses of instances that are associated with the source security group (not the public IP or Elastic IP addresses).

aws ec2 authorize-security-group-ingress \
    --group-id sg-1234567890abcdef0 \
    --protocol tcp \
    --port 80 \
    --source-group sg-1a2b3c4d

This command produces no output.

[EC2-VPC] To add one rule for RDP and another rule for ping/ICMP

The following example uses the ip-permissions parameter to add two rules, one that enables inbound access on TCP port 3389 (RDP) and the other that enables ping/ICMP.

(Windows):

aws ec2 authorize-security-group-ingress ^
    --group-id sg-1234567890abcdef0 ^
    --ip-permissions IpProtocol=tcp,FromPort=3389,ToPort=3389,IpRanges=[{CidrIp=172.31.0.0/16}] IpProtocol=icmp,FromPort=-1,ToPort=-1,IpRanges=[{CidrIp=172.31.0.0/16}]
