If the drywall is directly onto the concrete, drill into the concrete and use a shield and screw or there is a concrete screw called Tapcon that screws directly into the concrete without a shield and holds much better. If the drywall is on furring strips, either mount the banister on the strips or go through the strips into the concrete.
anchor bolts made for concrete
An anchor bolt is used to attach things or structures to concrete. Anchor bolts are used on all types of projects. They are used on dams and nuclear power plants.
Anchor bolts are used to secure items to concrete. They can be wet-set meaning inserted into the concrete while it is still hardening or the concrete can be drilled and the anchors set in to them.
The best concrete anchor for households is hammer-in-anchors. Hammer-in-anchors are easy to install and don't require separate screws, but cannot be used on crumbly surfaces.
A mechanical anchor is a load-carrying device that does not depend on glue or resin to support the loads. An example is a simple steel screw fixed into a wooden post to hold up the weight of a picture. However, the term "mechanical anchor" usually refers to a steel device which is fixed into a hole in a concrete beam or slab. The steel anchor resists load by a combination of friction and mechanical interlock with the concrete surface within the hole. The steel anchor contains some mechanism within itself to press the sides of the anchor (which are often toothed) into the concrete.
You should never anchor a wall arm like this into just drywall. It is very dangerous. You will need to find a wall stud under the drywall to anchor this into.
A quality drywall anchor depends on the merchant you purchased it from. Sometimes the cheaper they are, the worse they are. Don't be afraid to spend a little more money for quality.

Drywall anchors are small devices used to hold heavier items you plan on placing upon walls, especially if you don't plan on using the studs. You typically drill a hole where you plan to mount whatever it is you're mounting, screw the drywall anchor in, and then place the screw inside the anchor. The drywall anchor will hold tight to the wall so things don't fall or ruin your wall.

Drywall anchors should be placed no more than 16" apart. On a 20 foot wall you should place approximately 15 drywall anchors.
A cement anchor is a general term to describe a fastner that is attached to concrete. Common concrete anchors have a lead tip that mushrooms and "grabs" the concrete. Usually a hole is first drilled into the concrete. Then a concrete anchor is driven into the hole using a hammer. This allows for attaching wood or metal to concrete.
If you are attaching it to drywall, use plastic anchors with the screws. The anchor expands while the screw is being installed and helps hold the fixture firmer to the wall. If the fixture is kind of heavy, use a "butterfly" anchor (the hardware store clerk will know what you want). Butterfly anchors open up like a butterfly's wings behind the wall as you insert the screw.

Concrete anchor belts and bolts are used for large concrete structures when the foundations are being put down. They are sometimes removed later on without harming the buildings foundation.

If there's any question about whether or not a drywall anchor will hold on the ceiling, the best thing to do would be to find a ceiling joist and use a long screw to go into solid wood. (Use a stud finder to locate the joist.) Hanging on a ceiling is more dangerous than hanging on a wall since things that fall can fall on people or pets. If you HAVE to hang just in drywall, use the strongest anchor you can get (i.e. one that expands like a butterfly after insertion, or the type that flares out like a flower when you tighten it). Your local hardware store can help with what's a reasonable weight limit.
