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. 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






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






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






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






5. removable media - email attachments - web browsing - social networking - network vulnerabilities - IM applications - p2p






6. One is for talking - one is for implementing






7. 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






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






9. Considered to be a perimeter device






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






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






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






13. 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






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






15. When someone has compromised the integrity of data or a program. Allows attackers to create backdoors.






16. Confidentiality - integrity - availability






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






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






19. 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.






20. Network scanner.






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






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






23. 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






24. Malware - insider threat - natural disaster - terrorism - pandemic






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






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






27. Anonymous FTP - FTP passes through clear text - Bounce attacks with the PORT command - user can cause an FTP to open a connection from the FTP's own commands and bypass a firewall






28. 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






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






30. Known - unknown - zero day






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






32. Maintains complete TCP connection state and sequencing through 2 connections - address translation built-in by virtue of second connection above






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






34. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






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






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






37. It interacts with data and prepares it to be transmitted across the network. It ensures reliable connectivity from end-to-end






38. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






39. packet filter firewalls rely on TCP flags to determine connection state. Attacker can send ACK packets only to bypass firewall.






40. True positive - false positive - true negative - false negative






41. 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






42. 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






43. 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






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






45. Infects the EXE and make them operate slightly different - when infected - exe header sizes are altered to point to the appended viral code






46. 53 bytes - 48 bytes for data - 5 bytes for the header






47. Confidentiality - integrity - availability






48. Allows segmentation of a switch into different networks - regardless of where a system is plugged in - creates separate networks through software not hardware
