Property Validation - YEAR validation on an Integer Property

I have a property in a Section that has been originally defined as an Integer Property Type. User needs to enter a YEAR for this property in a Section.

I need to validate (from the front end) that the user is entering a four digit year in the field in the section.

When I open the (Magnifier Glass of the) Property on the Section, I see two additional options viz. Control and Behavior. Can you suggest how I may use the Control and/or Behavior to make sure that User enters a valid year on the Section.
