QUESTION 4

1. The chief characteristic of a Smurf attack is that an attacker

   		Uses a "cannon" to send an extremely large packet to overwhelm a target device
   		Requests that a huge amount of devices send ICMP responses to a target IP address
   		Requests a huge number of connections that they have no intention of completing, effectively overhelming the target's resources
   		Uses the Smurf virus to cause a buffer overflow in the network software of a target

QUESTION 5

1. The Internet was designed to scale to nearly unlimited connected devices - How does this relate to common network attacks?

   		It doesn't - Any one network device can only receive traffic from one other device at a time
   		Having so many devices on the Internet makes it tougher to target any single specific device
   		Many network attacks rely on tricking a large number of devices to target and overwhelm a single device or network
   		As the Internet grows larger, it makes it more difficult for an attacker to scan all of the available IP addresses - This causes a reduction in the number of attacks they can launch

QUESTION 6

1. Choose the network component that is used to connect two or more networks

   		Router
   		Switch
   		Hub
   		DataCom

QUESTION 7

1. What drawback of older protocols like Ethernet or IPv4 allow attackers to "spoof" or forge packets with the source address of another device?

   		Ethernet and IPv4 allow for using up to 5 source addresses
   		Ethernet and IPv4 allow packets to be created with any source address, with no verification
   		Ethernet and IPv4 don't enforce maximum packet sizes, making it possible to include additional source addresses in a data packet
   		Ethernet and IPv4 do authenticate source addresses, but attackers have cracked the process because it is old

QUESTION 8

1. True or False - Because the predecessor of the Internet was developed for the Department of Defense, advanced security measures were built into the main protocols used on the Internet

   True

   False

QUESTION 9

1. Protocols like Ethernet and IPv4 do not protect the confidentiality of the data they carry - This makes them susceptible to

   		Cracking
   		Hashing
   		Flooding
   		Eavesdropping

QUESTION 10

1. The chief characteristic of a SYN flood attack is that an attacker

   		Uses a "cannon" to send an extremely large packet to overwhelm a target device
   		Requests that a huge amount of devices send ICMP responses to a target IP address
   		Requests a huge number of connections that they have no intention of completing, effectively overhelming the target's resources
   		Uses the Smurf virus to cause a buffer overflow in the network software of a target
