Question:

What is the difference between the deny and reject in security policy

Answer:

Deny: Select deny to silently discard the packets without sending a TCP reset packet or an ICMP destination-unreachable message to the sender.

Reject: Select reject to discard the packets and send a TCP reset packet or an ICMP destination-unreachable message to the sender.
