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. Used to pass data from one VLAN to another






2. Crashing a computer by sending oversized packets (over 64 bytes) that it doesn't know how to handle






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






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






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






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






7. 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






8. Bastion host - dual homed firewall - multi homed firewall - screened host - screened subnet






9. One device per network segment - does not use local system resources - can't examine encrypted traffic - OS independent - less expensive






10. Creating a illegitimate website with the intention of convincing victims that they are visiting a legitimate site - typically to collect confidential information






11. Amplifies the signal of incoming packets before broadcasting them to the network






12. Twisted pair cable with speed capability of 1Gbps






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






14. IDS response method using logging and notification






15. Multiple network defense components are placed throughout the organizations assets and the network is properly segmented






16. Allows all traffic except traffic that is specifically denied - also known as permissive access






17. A group of hosts on logical network segment that communicate as if they were attached to the same broadcast domain - regardless of their physical location






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






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






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






21. Cable used most in networks - maximum speed 1Gbps - maximum length 100 meters - susceptible to tap






22. Known as thinnet - 10mbps - limited to 185 meters






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






24. Bbenign activity reported as malicious






25. Attack where an attacker intercepts traffic and tricks parties at either end into believing they are communicating with each other






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






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






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






29. 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






30. Dynamic / private ports






31. Session hijacking countermeasure






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






33. 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






34. Twisted pair cable with speed capability of 10Mbps






35. Collection on honeypots






36. Firewall with several NICs connected to different networks






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






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






39. Level 1 firewall that looks at the head of a packet - (not content) - operates rapidly - application independent - either allow or deny packets






40. 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






41. Firewall with two NICs - one internal and one external facing - NAT is often used with this firewall






42. Variation of the SYN flood where SYN packets are spoofed to have the same source and destination IP address and port






43. Capture and analyze network traffic - also known as packet analyzer - sniffer - network analyzer






44. Man in the middle attack where the content of an intercepted message is altered before it is sent on






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






46. Head of a packet contains...






47. Cable designed for transmission at higher speeds (100Mbps - 2Gbps) and longer distances (2km) - expensive -eliminates signal tapping






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






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






50. An attacker redirects valid request to malicious sites by feeding a DNS server altered records which are retained in its cache
