Information
Aべからず is an old-fashioned written expression used to strongly forbid something. Usually appears on signboards and the like, though in modern Japanese it is generally replaced with 禁止、な、てはいけない、てはならない.
べからざる is the noun modifying form, meaning "cannot" or "should not". Generally limited to few set expressions like 許すべからざる、ありうべからざる、欠くべからざる. Rarely used.
