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. Trivial File Transfer Protocol - method to transfer files from one device to another without needing authentication






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






3. It interacts with the application layer to determine which network services will be required






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






5. 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






6. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






7. Simple attack done by simply browsing available information that's allowed on a local network.






8. Considered to be a perimeter device






9. 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






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






11. One is for talking - one is for implementing






12. Uses flow control to handle network congestion - can send larger amounts of data per packet - has guaranteed delivery of transmitted data - better protection against spoofing - reduces need for error checking at higher OSI layers






13. 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






14. deployment challenges including topology and access limitations - analyzing encrypted traffic - quantity vs. quality of signatures - performance limitations with extensive analysis techniques - very costly for proper management






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






16. 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






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






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






19. 1. physical 2. data 3. network 4. transport 5. session 6. presentation 7. application






20. Hash Authentication - asymmetric - non repudiation - digital signature - hash + asymmetry






21. A system resource that has no legitimate purpose or reason for someone to connect to it - its purpose is to draw in attackers to understand how they break into a system






22. 53 bytes - 48 bytes for data - 5 bytes for the header






23. Wide Area Network - Larger than MAN or LAN - uses public network - phone lines - and leased lines to tie LAN and MAN over a dispersed area






24. Migrate to WPA2 - use strong authentication like PEAP or TTLS - audit network installations - require mutual auth between client and infrastructure equipment






25. Provides insight into traffic on the network - help detect problems with network operations - provides auditing for other security measures






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






27. 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.






28. open source tool for monitoring - can be used as a NIDS - has quick updates and flexibility for custom rules






29. Work groups that require additional protection are segmented from the rest of the internal organization - restricting access to critical segments - system of VPNs - internal firewall - VLANs and ACLs






30. Multiple levels of protection must be deployed - an exercie in detection - measures must be across a wide range of controls - compromises happen when people leave sites - risk - CIA triad - strategies






31. Used for connecting two physical segments of a network - segments traffic - breaks up collision domains - not generally used because of switches






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






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






34. Full open - half open (stealth scan) - UDP - Ping






35. Going around with equipment to detect wireless networks






36. Uses a 1 to 1 substitution of arbitrary numbers - given a one character mapping - you cannot determine the key






37. Stateful firewalls maintain state of traffic flows






38. 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






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






40. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






41. UDP based infection - infected through vulnerability in SQL server - caused DoS on saturated networks






42. Physical layer - Data link layer - Network Layer - Transport Layer - Session Layer - Presentation Layer - Application Layer






43. 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






44. Attempt to manipulate or trick a person into providing information or access - bypass network security by exploiting humans - vector is often outside attack by telephone or visitor inside






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






46. keeps the same letters - but changes the position within the text - easy to break - can be combined with substitution
