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. The practice of sending an ACK inside another packet going to the same destination






2. Take the file and try to compress it. If it compresses - it means there is a pattern and it's more easily crackable

3. A low end firewall that can quickly be deployed using existing hardware. They examine packets themselves with no content.






4. An appliance that controls access between public internet and a companies private network - or between a PC NIC and the rest of the PC.






5. 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






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






7. Worms and Wireless - modems - tunnel anything through HTTP - social engineering






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






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






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






11. 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






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






13. Combines the functionality of a hub and bride into a single device - keeps track of MACs attached to each port






14. A list of files is defined that should be monitored for a change - HIDS software calculates a one-way hash for each file - if a change is made to the file - the hash is changed






15. Intrusion detection system - it reports attacks against monitored systems/networks






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






17. Used by IDS for a baseline before analysis - attackers will try to de-normalize traffic to evade detection - IDS will normalize data for understood protocols






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






19. 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






20. Going around with equipment to detect wireless networks






21. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






22. Weakness in a system - inherent in a complex system - majority are due to poor coding - gateway by which threats are manifested






23. Infected millions through various methods - vulnerability in the MS Server Service - brute force admin password through network shares - infect removable devices with a malicious autorun script






24. Confidentiality - integrity - availability






25. Parasitic malware - boot record infector - macro - COM/Script program infector - EXE program infector






26. Switches networks make it difficult to monitor traffic in promiscuous mode - topology must be able to support traffic aggregation for monitoring






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






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






29. TCP/IP - the IP protoco - The core routing protocol of the internet - - deals with transmission of packets between end points - defines the addressing scheme for the internet






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






31. 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.






32. Means multiple iterations won't matter. If you encrypt with a key - then re-encrypt - it's the same as using one key.






33. An attacker recruits zombie systems ahead of time to simultaneously release a flood of traffic at a specific target.






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






35. 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






36. 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






37. 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






38. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






39. A hash is produced when applied to a monitored file. The hash always generates the same value unless a change was made. HIDS software checks the hashes of monitored files and if a change is found - analyst is notified. - ie: tripwire






40. Message in its encrypted form






41. Uniform protection - protected enclaves - information centric - threat vector analysis






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






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






44. 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






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






46. Connects the physical part of the network (cables) with the abstract (packets and datastreams)






47. Unencrypted message in its original form






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






49. FIN 130 - ACK 131 - FIN 570 - ACK 571






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