證明原則的範例

發行項
08/08/2024

證明原則會用來處理證明證據，並判斷 Azure 證明是否會發出證明權杖。您可以使用自訂原則來控制證明權杖的產生。以下是證明原則的一些範例。

Software Guard Extensions (SGX) 記憶體保護區的範例自訂原則

version= 1.0;
authorizationrules
{
       [ type=="x-ms-sgx-is-debuggable", value==false ]
        && [ type=="x-ms-sgx-product-id", value==<product-id> ]
        && [ type=="x-ms-sgx-svn", value>= 0 ]
        && [ type=="x-ms-sgx-mrsigner", value=="<mrsigner>"]
    => permit();
};
issuancerules {
c:[type=="x-ms-sgx-mrsigner"] => issue(type="<custom-name>", value=c.value);
};

如需 Azure 證明所產生的傳入宣告詳細資訊，請參閱宣告集合。原則作者可以使用傳入宣告在自訂原則中定義授權規則。

發行規則區段並非必要專案，但可用來在證明權杖中產生其他具有自訂名稱的傳出宣告。如需證明權杖中的服務所產生的傳出宣告之詳細資訊，請參閱宣告集合。

SGX 記憶體保護區的預設原則

version= 1.1;
configurationrules{
	=> issueproperty(type="x-ms-sgx-tcbidentifier", value="azuredefault");
};
authorizationrules{
	=> permit();
};
issuancerules{
	c:[type=="x-ms-sgx-is-debuggable"] => issue(type="is-debuggable", value=c.value);
	c:[type=="x-ms-sgx-mrsigner"] => issue(type="sgx-mrsigner", value=c.value);
	c:[type=="x-ms-sgx-mrenclave"] => issue(type="sgx-mrenclave", value=c.value);
	c:[type=="x-ms-sgx-product-id"] => issue(type="product-id", value=c.value);
	c:[type=="x-ms-sgx-svn"] => issue(type="svn", value=c.value);
	c:[type=="x-ms-attestation-type"] => issue(type="tee", value=c.value);
};

預設原則中使用的宣告會被視為已淘汰，但受到完全支援，且未來將繼續包含。建議使用未淘汰的宣告名稱。如需建議宣告名稱的詳細資訊，請參閱宣告集合。

};
