how to expose limited number of operation contracts to a service consumer? - wcf

Question

I have a Service Contract with 5 operations contracts and hosted in IIS.
Let suppose I have 2 Service Consumer A & B.
I need to give access to all 5 operations contracts to Service Consumer A, but
for Service Consumer B, I need to give access to only 2 out of 5 operations contracts.
What settings we need to do to expose only 2 operations contracts to Consumer B?
Thanks

From Tim's Comment I would create the two contracts and have two endpoints but you would only need one implementation like follows
[ServiceContract]
public interface IService_AdminLvl : IService_USERLvl
{
[OperationContract]
string setData(int value);
[OperationContract]
string setData2(int value);
}
[ServiceContract]
public interface IService_USERLvl
{
[OperationContract]
string GetData(int value);
[OperationContract]
string GetData2(int value);
[OperationContract]
string GetData3(int value);
}
public class Service1 : IService_AdminLvl
{
//IMPL ALL FUCNTIONS
public string GetData(int value)
{
throw new NotImplementedException();
}
public string GetData2(int value)
{
throw new NotImplementedException();
}
public string GetData3(int value)
{
throw new NotImplementedException();
}
public string setData(int value)
{
throw new NotImplementedException();
}
public string setData2(int value)
{
throw new NotImplementedException();
}
and a config something like this...
<service name="domainName.Service_2">
<endpoint address="admin" binding="basicHttpBinding" contract="domainName.IService_AdminLvl">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="user" binding="basicHttpBinding" contract="domainName.IService_UserLvl">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
</service>
