Describe one of the two risks within the OSI network model's Transport layer.
What will be an ideal response?
Within the Transport layer, there are two great risks. The first is handling sequence numbers. TCP segments are assigned sequential numbers to track their sequences. By guessing these sequence numbers, attackers can hijack TCP communications and attack either endpoint. The other great risk is the port assignments given the various services provided at higher layers. The combined Network layer address and Transport layer port socket provides insight into the function and operation of network-available services. Knowing the ports available allows attackers to infer the listening services or applications and thus provide the necessary intelligence to use to stage an attack. Port scanners are commonly used to identify this information, as systems are commonly configured to respond to requests about available services as part of normal network operations.
