10. 10What is Packet Inspection?

    1. AOpens IP Packets and looking beyond basic network protocol information and can tell the difference between different ports and applications
    2. BAllows packets to pass or halt based on the source and destination IP address, protocols and ports
    3. CInspects the actual data in the packets to check that the packet does not have malicious or unauthorized content

11. 11What is packet filtering?

    1. AOpens IP Packets and looking beyond basic network protocol information and can tell the difference between different ports and applications
    2. BAllows packets to pass or halt based on the source and destination IP address, protocols and ports
    3. CInspects the actual data in the packets to check that the packet does not have malicious or unauthorized content
12. 12What kind of things does Packet Filtering look at?

    1. ADestination IP
    2. BSource IP
    3. CDestination Port
    4. DSource Port
    5. EApplication data
13. 13What is stateful packet inspection?

    1. AMonitors the state of active connections and uses information to determine which network packets to allow through the firewall
    2. BInspects all layers of a packet to specifically allow or deny information pieces of information inside a packet
    3. COpens IP Packets and looking beyond basic network protocol information and can tell the difference between different ports and applications
14. 14Packet Filtering Firewalls are the.....

    1. ASimplest type
    2. BMost complex type
    3. CBest performing
15. 15What do Packet filtering firewalls permit/deny based on?

    1. AIP Address and TCP Port
    2. BIP Address and Protocol Port
    3. CApplication and Port

19. 19What are Packet Filtering Firewall susceptible to?

    1. ASpoofing
    2. BHacking
    3. CAllowing malicious content through
20. 20What do Stateful Inspection Firewalls do?

    1. ATracks each connection made through all interfaces on the firewall to make sure they are valid
    2. BPermits/denies based on IP Addresses and TCP Port
    3. CExamines all layers of the Protocol stack
21. 21All modern firewalls perform stateful inspection

    1. AVerdadero
    2. BFalso
22. 22What layer does the Stateful Inspection Firewall analyse down to?

    1. AApplication
    2. BTransport

    1. AForm of firewall that controls input, output, and/or access from, to, or by an application or service
    2. BTracks each connection made through all interfaces on the firewall to make sure they are valid
    3. CPermits/denies based on IP address and TCP port
