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






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






3. A sends a SYN packet to B - B acknowledges with a SYN/ACK - A replies with ACK






4. 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






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






6. OSI






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






8. Outside attack from network - Outsider attack from telephone - Insider attack from local network - insider attack from local system - attack from malicious code






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






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






11. 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






12. True positive - false positive - true negative - false negative






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






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






15. Prepends to the beginning of the file and gains control when the first instruction of the infected COM file is executed - appending to the end - virus writes its payload to the end and inserts jump instruction as the first instruction - which execute






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






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






18. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






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






20. It handles the establishment and maintenance of connections between systems






21. Connection oriented - before systems can communicate over an ATM network - they must establish a virtual circuit between each other - this can span across multiple ATM switches that also handle communications for other systems - at the end of the con






22. Known - unknown - zero day






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






24. Syn - Syn/Ack - Ack






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






26. 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






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






28. 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






29. Relies on executable code insertion and user interaction to spread






30. Poor programming without error checking can allow commands to be run in an input field. This can point to a command further in the buffer that will execute the attacker's payload.






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






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






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






35. 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.






36. Metropolitan area network - spans across city or town - larger than a LAN - uses fiber for backbone






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






39. Handles the network address scheme and connectivity of multiple network segments. It handles communication.






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






41. Network traffic to the host - typically listens on all interface - uses signature analysis to identify events of interest






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






43. Not a replacement for firewalls - hardening - strong policies - or other DiD methods - low maintenance - inexpensive






44. Bits of code embedded in programs to quickly gain access at a later time






45. Unified data carrying service - replacing from replay and ATM






46. Common backdoor to open a port - port scan scans for open ports on remote host - scans 0 - 65 -535 twice. TCP and UDP






47. ATM supports two types of virtual circuits: permanent virtual circuits and switches virtual circuit - PVC is set up in advance - usually manually - SVC is established automatically through a signaling protocol and can be created on the fly - establis






48. Intellectual property - business goals - validated data - historical






49. 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






50. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0
