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. Protocol used to map an known IP address to its corresponding media access control (MAC) address






2. Malicious activity not reported or detected






3. An attack where fragmented UDP packets with odd offset values are sent to the victim - when the OS attempts to rebuild the fragments they overwrite each other and cause confusion






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






5. One process on every system - use local system resources - detect attacks that NIDS misses - examine data after decrypted - can be OS specific - more expensive






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






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






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






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






10. 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






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






12. A method - used by switches and email servers - of delivering messages which are temporarily held by an intermediary before being sent to their final destination






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






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






15. Bbenign activity reported as malicious






16. Examines a entire packet and determines action based on a complex set of rules






17. A sniffer mode used to capture traffic addressed to/from another machine on the network






18. Head of a packet contains...






19. IDS response method using logging and notification






20. Firewall that intercepts and inspects messages before delivering them - placed between trusted and untrusted networks - degrade network traffic - also know as application gateway






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






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






23. 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






24. Promiscuous NIC to sniff passing traffic - admin NIC to send alerts to centralized management system






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






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






27. Session hijacking countermeasure






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






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






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






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






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






33. Firewall with several NICs connected to different networks






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






35. Evolved from IDS - monitors network traffic - detects and responds to attack on network






36. Used to pass data from one VLAN to another






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






38. When a hacker takes over a TCP session between two machines - also known as session hijacking - foiled by the use of encrypted sessions






39. A flaw in TCP/IP to verify that a packet really comes from the addess indicated in the IP header leads to this attack






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






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






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






43. Twisted pair cable with speed capability of 1Gbps






44. 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






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






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






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






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






49. Level 2 firewall often used to filter web traffic






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