Synopsis

Calls the Amazon Elastic Compute Cloud (EC2) DescribeSecurityGroups API operation.

Syntax

Get-EC2SecurityGroup
-GroupId <String[]>
-Filter <Filter[]>
-GroupName <String[]>
-MaxResult <Int32>
-NextToken <String>
-Select <String>
-PassThru <SwitchParameter>
-NoAutoIteration <SwitchParameter>
-ClientConfig <AmazonEC2Config>

Description

Describes the specified security groups or all of your security groups. A security group is for use with instances either in the EC2-Classic platform or in a specific VPC. For more information, see Amazon EC2 security groups in the Amazon Elastic Compute Cloud User Guide and Security groups for your VPC in the Amazon Virtual Private Cloud User Guide. We are retiring EC2-Classic. We recommend that you migrate from EC2-Classic to a VPC. For more information, see Migrate from EC2-Classic to a VPC in the Amazon Elastic Compute Cloud User Guide.

This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

  • description - The description of the security group.
  • egress.ip-permission.cidr - An IPv4 CIDR block for an outbound security group rule.

AliasesFilters
-GroupId <String[]>
The IDs of the security groups. Required for security groups in a nondefault VPC.Default: Describes all of your security groups.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
AliasesGroupIds
-GroupName <String[]>
[EC2-Classic and default VPC only] The names of the security groups. You can specify either the security group name or the security group ID. For security groups in a nondefault VPC, use the group-name filter to describe security groups by name.Default: Describes all of your security groups.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesGroupNames
-MaxResult <Int32>
The maximum number of items to return for this request. To get the next page of items, make another request with the token returned in the output. This value can be between 5 and 1000. If this parameter is not specified, then all items are returned. For more information, see Pagination.
Note: In AWSPowerShell and AWSPowerShell.NetCore this parameter is used to limit the total number of items returned by the cmdlet.
In AWS.Tools this parameter is simply passed to the service to specify how many items should be returned by each service call.
Pipe the output of this cmdlet into Select-Object -First to terminate retrieving data pages early and control the number of items returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxItems, MaxResults
-NextToken <String>
The token returned from a previous paginated request. Pagination continues from the end of the items returned by the previous request.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.
In order to manually control output pagination, use '-NextToken $null' for the first call and '-NextToken $AWSHistory.LastServiceResponse.NextToken' for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of NextToken as the start point.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the GroupId parameter. The -PassThru parameter is deprecated, use -Select '^GroupId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'SecurityGroups'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.EC2.Model.DescribeSecurityGroupsResponse). Specifying the name of a property of type Amazon.EC2.Model.DescribeSecurityGroupsResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage.

Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>

This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Outputs

Amazon.EC2.Model.SecurityGroup or Amazon.EC2.Model.DescribeSecurityGroupsResponse
This cmdlet returns a collection of Amazon.EC2.Model.SecurityGroup objects. The service call response (type Amazon.EC2.Model.DescribeSecurityGroupsResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.

Examples

Example 1

Get-EC2SecurityGroup -GroupId sg-12345678
    
Description         : default VPC security group
GroupId             : sg-12345678
GroupName           : default
IpPermissions       : {Amazon.EC2.Model.IpPermission}

OwnerId             : 123456789012
Tags                : {}
VpcId               : vpc-12345678
This example describes the specified security group for a VPC. When working with security groups belonging to a VPC you must use the security group ID (-GroupId parameter), not name (-GroupName parameter), to reference the group.

Example 2

Get-EC2SecurityGroup -GroupName my-security-group
    
Description         : my security group
GroupId             : sg-45678901

IpPermissionsEgress : {}
OwnerId             : 123456789012
Tags                : {}
VpcId               :
This example describes the specified security group for EC2-Classic. When working with security groups for EC2-Classic you may use either the group name (-GroupName parameter) or group ID (-GroupId parameter) to reference the security group.

Example 3
