There was not extra security from AMM-TLV or from TLV-AMM on RJ when I flew it last year. The only extra security on my JFK-AMM-TLV-AMM-ORD rount trip was the AMM-ORD leg.
A quick layover at AMM shouldn't be a problem, especially if you stay in either the east or west terminal (even then, switching between the terminals only adds 5 minutes).
