자세한 설명

The Get-NetIPsecMainModeSA cmdlet gets an active main mode security association (SA). This cmdlet is used for policy monitoring.

An SA is generated when main mode negotiation establishes a secure, authenticated channel between two computers. The SA is the information maintained about that secure channel on the local computer so that it can use the information for future network traffic to the remote computer.

An SA is the combination of a negotiated key, security protocol, and SPI, which together define the security used to protect the communication from sender to receiver. Therefore, by looking at the security associations for this computer, which computers have connections with this computer can be determined, which type of data integrity and encryption is being used for that connection, and other information. This information can be helpful when testing IPsec policies and troubleshooting access issues.

There are four mandatory parameters that negotiated as part of the main mode SA:
-- The computer authentication method: Kerberos v5, certificate, or pre-shared key (PSK) authentication, provided by the NetIPsecPhase1AuthSet object.
-- The encryption algorithm, provided by the NetIPsecMainModeCryptoSet object.
-- The hashing algorithm, provided by the NetIPsecMainModeCryptoSet object.
-- The Diffie-Hellman (DH) key exchange group to be used for the base keying material, provided by theNetIPsecMainModeCryptoSet object.

매개 변수

-All

Indicates that all of the main mode security associations within the specified policy store are retrieved.

-AsJob

-AssociatedNetIPsecQuickModeSA<CimInstance>

Gets the quick mode security associations associated with the given main mode security association.

-CimSession<CimSession[]>

원격 세션에서 또는 원격 컴퓨터에서 cmdlet을 실행합니다. New-CimSession 또는 Get-CimSession cmdlet의 출력과 같은 컴퓨터 이름이나 세션 개체를 입력합니다. 기본값은 로컬 컴퓨터의 현재 세션입니다.

-Name<String[]>

Specifies that only matching main mode rules of the indicated name are retrieved. Wildcard characters are accepted.
This parameter acts just like a file name, in that only one rule with a given name may exist in a policy store at a time. During group policy processing and policy merge, rules that have the same name but come from multiple stores being merged, will overwrite one another so that only one exists. This overwriting behavior is desirable if the rules serve the same purpose. For instance, all of the firewall rules have specific names, so if an administrator can copy these rules to a GPO, and the rules will override the local versions on a local computer. Since GPOs can have precedence, if an administrator that gives a rule with a different or more specific rule the same name in a higher-precedence GPO, then it overrides other rules that exist.
The default value is a randomly assigned value.
When the defaults for main mode encryption are overridden, specify the customized parameters and set this parameter value, making this parameter the new default setting for encryption.

-ThrottleLimit<Int32>

이 cmdlet을 실행하도록 설정할 수 있는 최대 동시 작업 수를 지정합니다. 이 매개 변수가 생략되거나 값 0이 입력되면 Windows PowerShell®은 컴퓨터에서 실행 중인 CIM cmdlet의 수에 따라 cmdlet에 대한 최적의 제한 한도를 계산합니다. 제한 한도는 현재 cmdlet에만 적용되며 세션이나 컴퓨터에는 적용되지 않습니다.

<CommonParameters>

이 cmdlet은 일반 매개 변수 -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer 및 -OutVariable을 지원합니다. 자세한 내용은 다음을 참조하세요. about_CommonParameters(https://go.microsoft.com/fwlink/p/?LinkID=113216).

입력

입력 유형은 cmdlet에 파이프할 수 있는 개체의 유형입니다.

• Microsoft.Management.Infrastructure.CimInstance#root\StandardCimv2\NetIPsecQuickModeSA

  Microsoft.Management.Infrastructure.CimInstance 개체는 WMI(Windows Management Instrumentation) 개체를 표시하는 래퍼 클래스입니다. 파운드 기호(#) 뒤에 오는 경로는 기본 WMI 개체의 네임스페이스 및 클래스 이름을 제공합니다.

출력

출력 유형은 cmdlet이 내보내는 개체의 유형입니다.

• Microsoft.Management.Infrastructure.CimInstanceroot\StandardCimv2\NetIPsecMainModeSA[]

  Microsoft.Management.Infrastructure.CimInstance 개체는 WMI(Windows Management Instrumentation) 개체를 표시하는 래퍼 클래스입니다. 파운드 기호(#) 뒤에 오는 경로는 기본 WMI 개체의 네임스페이스 및 클래스 이름을 제공합니다.

예제

EXAMPLE 1

This example returns all of the active main mode cryptographic sets on the local computer.

PS C:\> Get-NetIPsecMainModeSA –PolicyStore ActiveStore

Example 2

This example removes all of the active quick mode cryptographic sets associated with the specified main mode security association on a remote computer.

PS C:\> $computer1 = "RemoteMachineName"

PS C:\> Get-NetIPsecMainModeSA –Name "196511" –CimSession $Computer1 | Remove-NetIPsecQuickModeSA –CimSession $computer1
