In my Urlybird DB interface i have an unlock method which throws a RecordNotFoundExecption and SecurityException.
Im wondering how should i handle the SecurityException in my service layer? If the exception is thrown in the first place it means that someone is violating the rules of the api. There doesnt seem to be any point bubling this up to the UI layer?

You should not handle this exception, because it indicates wrong api usage.

If you don't want to fail automatically you should not make any changes to the interface you got. In my opinion the SecurityException should be a runtime exception, not a checked exception. Using the search engine of this forum, you'll can find many threads about this topic, e.g. this one.

As long as you provide a valid override, you don't have to worry (I followed same approach), but if it's declared as a runtime exception no need to override these methods

I was concerned that because the SecurityException appeared in the throws clause of the Sun interface that it had to be declared as checked but declaring as unchecked makes alot more sense.
The other reason I override the method is because i dont want to throw RNFE so my override just looks like this.
