Test your basic knowledge |

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. Protected at rest - protected in transit - secure the key






2. Trying to ID modems in a telephone exchange that may be susceptible to compromise






3. Good for multimedia - can use small single packets - multicasting is required - speed is the highest priority






4. Attaches itself to existing program files and activated when the exe is launched






5. free windows based wireless scanner for 802.1b - detects access point settings - supports GSP integration - identifies networks as encrypted or unencrypted






6. A cracking tool inserted into the OS that allows the attacker to do as they please.






7. Publish separate mail - web - and DNS servers to the internet - provide appropriate access from internal network to internet - protect internal from external attack - provide defense in depth - protect all aspects of the system






8. low interaction production honeypot - network daemon that can simulate other hosts - each host can appear as a different OS






9. Infects MBR - no network spreading potential






10. 1 and 2 - Voice/Low speed data - 3 - Voice/Data 10Mb - 4 - Voice/Data 16Mb - 5 - 5e - Voice/Data 100Mb to 1Gb - 6 - Standard for gigabit






11. risk = threat x vulnerability - impossible to eliminate - security is an exercise in loss reduction






12. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






13. A spoofed IP is used to send a SYN to the target. It then responds with a SYN/ACK that never receives the final ACK to complete the handshake. This occupies a portion of the target's pre-established buffer for TCP and can prevent the target from acce






14. Strips OS commands and characters from input - avoid making system calls from within the app * especially based on user input






15. It allows the transport layer to detect when the UDP headers or the payload have been modified in transit






16. Handles transmissions across the physical media like wires - fiber - etc






17. A time of check/time of use attack that exploits the difference in between when a security control was applied and the time the service was used.






18. size is whatever the length of the UDP portion of the packet. Could be as large as 65 -535






19. OSI






20. Most commonly used transport protocol today - ensures reliable packet delivery - has error handling built in






21. Protocol for mapping an IP address to a physical machine address that is recognized on the local network. A table - usually called the ARP cache - is used to maintain a correlation between each MAC and its corresponding IP address






22. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






23. Switches along the path can be requested to allocate the desired amount of bandwidth. If the circuit has the required bandwidth - the circuit is set up.






24. True positive - false positive - true negative - false negative






25. Protocol for mapping an IP address to a physical machine address that is recognized on the local network - A table - usually called the ARP cache - is used to maintain a correlation between each MAC and it's corresponding IP address






26. Personal area network - phone tethering - bluetooth - etc






27. CIDR is a shorthand way of specifying which portion of the address is the network - and which portion is the host






28. Resource exhaustion like DDoS or fork attack - unexpected input value the machine does not know how to process






29. Message in its encrypted form






30. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






31. logic bomb - trojan horse - trap door






32. Small program triggered by an event that provides an action. E.g. scheduled file removal if countdown isn't reset - ie: employee was fired






33. rules indicate criteria in packets that represent events of interest - rules are applied to packets as they are received - alerts are created when matches are found






34. Free linux WLAN analysis tool - completely passive - cannot be detected - supports advanced GPS integration and mapping features - used for wardriving - WLAN vulerability assessment






35. Protects internal/external systems from attack - filters communications based on content - performs NAT - encrypts communications for VPN - logging to aid in intrusion detection






36. An agreement on how different computer will work - protocols define the format and order of messages and what to do upon receipt of the messages - basically the rules of the network






37. Threat requires a vector to cross the vulnerability - stop the ability of the threat to use the vector






38. Spread as an office attachment with executable code programmed using macro facility - targets are data files - visual basic editor and other macro languages - payload executes when the code is launched






39. Four layers - Network Layer - Internet Layer - Transport Layer - Application layer






40. An FTP that allows downloads only if the user knows the exact name of the file they're looking for






41. Program disguised as something helpful - only to perform actions the user did not intend. Opening ports - installing other programs - etc.






42. Slow - requires stateful data tracking - inspects all fields - including variable-length fields






43. It makes sure the data sent from one side to the other is in a format useful to the other side

45. NTP - BootP/DHCP - NFS file systems - SNMP - TFTP






46. Unencrypted message in its original form






47. Replicates traffic onto all ports - no traffic monitoring - cannot control which ports should or shouldn't receive frames - forming a large collision domain.






48. Not frequently seen on LANs because of expense - because of its traffic predictability and high bandwidth support - it's good for video streaming - encapsulates common protocols - uses virtual path identifiers to create end to end connectivity - has






49. War dialing - war driving - Sniffing - eavesdropping - dumpster diving - social engineering
