I try to setting up a security and it seems that the Default Security Zone let tags readWrite access even I setup Service Security or not.
I just want that all PCs can have access to the tag but only PCs in dedicated Zone can Write to the tags.
I want to know if I do something wrong? If, yes, what it is ??
You will want to make sure you specify whether the default zone will define the read only zone or the read/write zone. Once you configure your CT002 zone, you will want to move it up above the default zone on the Service Security page or it will do nothing. Watch this video and make sure you have followed all of the other steps completely.
