Both nouns mean 'ban, prohibition​' and both verbs 'forbid'. I expect that in
set combinations, such as 禁煙 for 'no smoking', there is only one correct
possibility. But, otherwise, what's the difference?

Difference between 禁 and 禁止 (and 禁じる/禁止する)
**As nouns:**

  * 禁 is not commonly used as a noun, it is almost always used as a bound morpheme if you use it like a noun, it would sound antiquated, like you are quoting from an old book

> 「沈黙{ちんもく}は金{きん}どころか、禁{きん}である」

_As a bound morpheme, it is very common 解禁{かいきん}、厳禁{げんきん}、禁煙{きんえん}_

  * 禁止 is the common noun for banning or prohibiting, but most commonly it is made into a verb

_("ban" or "prohibition" as nouns would probably be translated 禁止令{きんしれい} or
禁止法{きんしほう})_

**As verbs:**

  * 禁じる・禁ずる has an antiquated feel to it, heavy and serious, like "to forbid"

  * 禁止する is neutral and common, just meaning to "ban", "prohibit", "not allow" etc.
