Resources on Layers 1 and 2

I am a graduate student doing research on security at Layer 1 and Layer 2 and am finding limited information. I read the article by Julie Bort, which was very informative and gave me some ideas. Is there anything you can provide further?
Layer 1 is the physical layer of the ISO/OSI reference model. As such, the primary security that can be provided is physical protection. This includes protected conduit and other means.

At Layer 2 (Data Link Layer) one can actually start encrypting data. Layer 2 Tunneling Protocol (L2TP) was developed to effectively make a layer 2 encrypted stream across another network. Microsoft's Point to Point Tunneling Protocol (PPTP) is based on L2TP.

The ISO Lower Layer security model (ISO/IEC TR 13594) and its companion Upper Layer security model (ISO/IEC 10745:95) are both available from the ISO (for a fee) at http://www.iso.ch.
