The only security checkpoints that you pass through are at the entrances to the concourses, or as the case is in Denver, leaving the terminal heading north as in your diagram. As you are arriving in "B" and leaving from "B", the only security you will see is actually at the airport you originally flew out from.
Since you are not changing concourses the time you have available is fine. That concourse has 27 gates...It is about 400-500 yards in length.
