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






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






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






4. 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






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






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






7. Twisted pair cable with speed capability of 10Mbps






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






9. Malicious activity not reported or detected






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






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






12. IP - email - website - DNS - and ARP






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






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






15. A physical or logical subnetwork that houses systems accessible to a larger untrusted network - usually the Internet - also known as DMZ






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






17. Ping flooding - ping of death - smurf - fraggle - SYN flood - land - teardrop - email flood






18. IDS response method using logging and notification






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






20. Known as thicknet - 10mbps - limited to 500 meters






21. 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






22. Dynamic / private ports






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






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






25. An application layer gateway works at this layer of the OSI model






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






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






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






29. Twisted pair cable with speed capability of 1Gbps






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






31. A locked down/hardened host on the public side of the firewall highly exposed to attacks (i.e. web server - email server)






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






33. 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






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






35. Head of a packet contains...






36. Session hijacking countermeasure






37. Attempt to block service or reduce activity by overloading the victim machine with ping requests






38. Collection on honeypots






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






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






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






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






43. A server that sits between an intranet and it's Internet connection - masking all IP addresses






44. A level 3 firewall that remembers / tracks network connections - maintains a state table - distinguish which side of a firewall a connection was initiated - higher security






45. User / registered ports






46. Firewall with several NICs connected to different networks






47. 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






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






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






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