Test your basic knowledge |

Comptia Security +: Network Security

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Variation of the SYN flood where SYN packets are spoofed to have the same source and destination IP address and port






2. Twisted pair cable with speed capability of 1Gbps






3. Type of IP addresses not routed on the internet: 10.x.x.x - 172.16.x.x - 192.168.x.x






4. Firewall that communicates directly with a perimeter router and the internal network - 2 NICs - screens internal traffic






5. Most common DMZ implementation using three firewall interfaces (internet - intranet - DMZ)






6. Unauthenticated connections - creating the potential for a successful connection as an anonymous user






7. Web servers - FTP servers - DNS servers - mail servers should be located on the _____________






8. A set of rules computers use to communicate with each other across a network






9. Head of a packet contains...






10. Collection on honeypots






11. A feature of firewalls / routers that disguise the IP address of internal systems allowing connection to the Internet using one public address






12. Forging an IP address with the address of a trusted host






13. Dynamic / private ports






14. A complete transfer of all DNS zone information from one server to another






15. A pool of public IP addresses is shared by a collection of private IP addresses






16. Firewall with several NICs connected to different networks






17. Used by ISPs - single public network IP address is shared among many hosts on a private network - also known as PAT






18. Malicious insiders - connections that bypass the firewall (i.e. IM) - encrypted traffic/tunneling - social engineering - physical access are missed by ___________






19. Well known ports - allow administrative access - used for network services - considered only ports allowed to transmit traffic thru a firewall






20. Session hijacking countermeasure






21. Take control of a session between a server and client - the users gets kicked off the session while the attacker inserts himself into the session by sending a reset request to the client






22. A firewall that checks all layers of a packet including content - verifying an expected response to a current communication session - also call a deep packet inspection






23. A logical division of a computer network - in which all nodes can reach each other by broadcast at the data link layer - equivalent to a VLAN






24. A logical connection point allowing computers and software to communicate and exchange data






25. A ping message is broadcast to an entire network with a spoofed source IP addess of the victim computer - flooding the victim computer with responses during this attack






26. Examines content passing through and makes a decision on the data based on a set of criteria - normal uses email filtering and web browsing






27. Network configuration that permits selected outsiders access internal information systems






28. IP spoofing attack where the attacker can only send packets and has to guess about replies






29. An attack where an attacker captures sensitive information and sends it again later in an attempt to replicate the transaction






30. Connects devices together to form a subnet - packet forwarding is based on MAC addresses - works at the data link layer of the OSI






31. Connects two or more subnets - determines the best path to forward packets based on packet header and forwarding table information






32. Monitors network traffic to identify possible attacks






33. A decoy system - intentionally left exposed to attract/distract attackers - logs and monitors attacker activities






34. User / registered ports






35. Packet filtering - proxies - stateful inspection






36. An attacker redirects traffic by falsifying the IP address requested by ARP request






37. Twisted pair cable with speed capability of 10Mbps






38. Unauthenticated Windows session where an attacker can gather list of users - groups - machines - shares - user and host SID






39. IP spoofing attack where the attacker can monitor packets and participate in bidirectional communication






40. A person or program masquerades as another by presenting false information to gain an illegitimate advantage






41. Cable with copper core - has no physical transmission security and is easy to tap - 10mbps - maximum length 500 meters






42. Generate random TCP sequence numbers and encrypt traffic countermeasure what attacks






43. Man in the middle attack where the attacker captures the traffic and sends it to the original recipient without altering the intercepted data






44. Two authoritative sources for your domain namespace with differing contents depending on whether the query is internal or external






45. A variation of a smurf attack using UDP






46. DMZ implementation using two firewalls with different rule sets for the DMZ and intranet






47. A DoS attack that subverts the normal "three way handshake" of TCP/IP by sending SYN packets - but no corresponding ACK packets






48. A logical group of computers connected via a switch/hub that share the same network prefix in their IP address






49. Connects devices together to form a subnet - broadcasts incoming packets to all devices






50. Seeks to reduce the probability and/or impact of a specific risk below an acceptable threshold
