Switches

Question 1

What types of attacks are Switches vulnerable to?

Answer 1

MAC Flooding
MAC Spoofing
Physical Tampering

Question 2

What is MAC Flooding?

Answer 2

An attempt to overwhelm the limited switch memory that is set aside to store the MAC addresses for each port.

Note: If the switch gets flooded, it can “fail-open” and start sending information out to every port.

Question 3

What is MAC Spoofing?

This occurs when an attacker masks their own MAC address to pretend they are another MAC address.

Note: MAC spoofing is often combined with ARP spoofing attacks.

The attacker gains physical access to the switch and can do a number of things to it.

Question 5

What layer of the OSI Model is the switch?
