[Rogue One] Is the empire's security apparatus entirely incompetent?

As seen in the movie, bodhi rook states that they were rerouted from eadu flight station, which apparently is enough to convince the shield apperture operating crew. I served time in my country's military and did guard duty, and this is against all base security protocol i've ever seen, why was no contact made with whoever is in charge of rerouting military flights? If sheev could contact clone commanders in the outer rim from coruscant, then an imperial officer can definitely contact space traffic control or an equivalent there-of. 

In addition, would there be no record that the shuttle approaching the shield apperture is missing? After all the rebel air traffic controller on yavin stated that it's an impounded imperial ship, so there must have must have been some suspicion about a missing shuttle, not scheduled to be there, suddenly showing up over scarif?

The shuttle also has proper code clearances, and with such a massive bureaucracy, information travels slowly. News of the attack on Eadu may or may not have reached Scariff yet, and whatever news did arrive was likely incomplete. The logistics of such a large empire are very complex, so an unscheduled arrival wasn't that uncommon.

Look at it from the Imperial perspective. They live and work on a quiet planet, protecting a giant library and some R&D stuff. No locals, no Rebel presence, just a calm beach world. Many Imperials worked there as a semi-retirement because it was a very easy, low stress assignment. Shuttles come in and out. Another shuttle comes in. The shuttle itself is undamaged and looks like every other shuttle. The pilot speaks in the same manner as every other pilot, and knows all the procedures. The codes they have transmitted are correct, and shuttles fly in and out from those sorts of research planets all the time. An unscheduled arrival, but that happens. Clear them, let them land, then inspect it just to be sure.

From an organizational perspective, the Empire knows nothing about Rogue One. They have no idea Galen put a weakness in the Death Star, or that Galen got a message out saying the plans were on Scariff. For all they know, the Rebels knew of the weapon and Galen's involvement, and then assassinated him to keep him from working on the project. Krennic went to Scariff to review the plans and ensure there had been no more breaches of security-nobody was expecting a Rebel attack at all. When the Rebels detonated the explosives, everyone was frozen by inaction, and only Krennic realized what was going on-is they expected a Rebel attack, deploying the garrison would have been step one. The Rebels caught everyone by complete surprise.
