Explanation:
The use of Ping with a packet size higher than 65 KB and no fragmentation flag on will cause a denial of
service. A brute force attack is typically a text attack that exhausts all possible key combinations. A leapfrog
attack, the act of telneting through one or more hosts to preclude a trace, makes use of user ID and password
information obtained illicitly from one host to compromise another host. A negative acknowledgement attack is
a penetration technique that capitalizes on a potential weakness in an operating system that does not handle
asynchronous interrupts properly, leaving the system in an unprotected state during such interrupts.
