What version of IIS are you using is usually a good thing to include in the question.

Older versions of IIS (5) use ASPNET and newer versions use Network Service.

You can adjust permissions as you normally do in Windows or via your Hosting Control Panel.

It's best practice to make this a new account that you can control the direct privileges too, since Network Service can have a bit higher level of permissions. You can change this under the Application Pool in IIS that your website hosting WCF is running as.

Then wherever your website needs the read/write access grant to this new account.
