Use RevokeSecurityGroupIngress with an Amazon SDK or CLI

Example 1: To remove a rule from a security group

The following revoke-security-group-ingress example removes TCP port 22 access for the 203.0.113.0/24 address range from the specified security group for a default VPC.

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

This command produces no output if it succeeds.

For more information, see Security groups in the Amazon EC2 User Guide.

Example 2: To remove a rule using the IP permissions set

The following revoke-security-group-ingress example uses the ip-permissions parameter to remove an inbound rule that allows the ICMP message Destination Unreachable: Fragmentation Needed and Don't Fragment was Set (Type 3, Code 4).

aws ec2 revoke-security-group-ingress \
    --group-id sg-026c12253ce15eff7 \
    --ip-permissions IpProtocol=icmp,FromPort=3,ToPort=4,IpRanges=[{CidrIp=0.0.0.0/0}]

This command produces no output if it succeeds.

For more information, see Security groups in the Amazon EC2 User Guide.

Example 1: This example revokes access to TCP port 22 from the specified address range for the specified security group for EC2-VPC. Note that you must identify security groups for EC2-VPC using the security group ID not the security group name. The syntax used by this example requires PowerShell version 3 or higher.

$ip = @{ IpProtocol="tcp"; FromPort="22"; ToPort="22"; IpRanges="203.0.113.0/24" }
Revoke-EC2SecurityGroupIngress -GroupId sg-12345678 -IpPermission $ip

Example 2: With PowerShell version 2, you must use New-Object to create the IpPermission object.

$ip = New-Object Amazon.EC2.Model.IpPermission
$ip.IpProtocol = "tcp"
$ip.FromPort = 22
$ip.ToPort = 22
$ip.IpRanges.Add("203.0.113.0/24")

Revoke-EC2SecurityGroupIngress -GroupId sg-12345678 -IpPermission $ip

Example 3: This example revokes access to TCP port 22 from the specified address range for the specified security group for EC2-Classic. The syntax used by this example requires PowerShell version 3 or higher.

$ip = @{ IpProtocol="tcp"; FromPort="22"; ToPort="22"; IpRanges="203.0.113.0/24" }

Revoke-EC2SecurityGroupIngress -GroupName "my-security-group" -IpPermission $ip

Example 4: With PowerShell version 2, you must use New-Object to create the IpPermission object.

$ip = New-Object Amazon.EC2.Model.IpPermission
$ip.IpProtocol = "tcp"
$ip.FromPort = 22
$ip.ToPort = 22
$ip.IpRanges.Add("203.0.113.0/24")

Revoke-EC2SecurityGroupIngress -GroupName "my-security-group" -IpPermission $ip
