What difference in security should there be between a small and large airport?

The short answer, none.

They both have the same goal of preventing security risks from disrupting travel.

And although one is typically less trafficked, security accuracy should not fluctuate.

Security is an established processes, reinvent the wheel regardless of the size of an airport has diminishing returns.

Don’t invest energy rebuilding what you don’t need to.
