Before revision: The Shortest Path Problem, in real-life applications, has to deal with multiple criteria.
After revision: The Shortest Path Problem, in real-life applications, has to deal with multiple attack layers e.g., man-in-the-middle, eavesdropping, packet injection, packet insertion, etc. Consider different probabilities for each such attack over an edge, probabilities that can differ across edges. Furthermore, usage of a single shortest path (for routing) implies possible traffic bottleneck, which should be avoided if possible, which we term pathneck security avoidance.
