Well, if you want to follow the NEC, all wiring that is exposed less than eight feet above ground is supposed to be protected by "some adequate means". Even low voltage wiring since this requirement falls under "wiring methods" in the code. I interpret this as cable guard or conduit.

Does anybody do it for low-voltage? Of course not! Would an electrical inspector bust you for not protecting it? I seriously doubt it. I would't worry about a short exposed length, just do the best you can to keep it out of harm's way and out of direct sunlight and it should be fine. If you need a short length of CAT5 cable that's outdoor rated, just let me know in a PM and I will send you some.
