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. 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






2. Confidentiality - integrity - availability






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






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






5. Attacks systems through known vulnerabilities - automatically scans for more systems to attack - lowers system defenses - installs rootkit or root shell - opens up back doors - self contained malware that can copy itself






6. 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






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






8. destruction of data - leaking confidential information - providing backdoor access






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






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






11. True positive - false positive - true negative - false negative






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






13. logic bomb - trojan horse - trap door






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






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






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






17. flags anomalous conditions in traffic on the network - requires understanding on what is normal - bases good traffic as a baseline






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






19. Network scanner.






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






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






22. Uses inclusive or exclusive lists - inclusive analysis utilizes a list of keywords - exclusive analysis utilizes a list of events that can be ignored






23. Message in its encrypted form






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






25. local area network - small network confined to small location - all equipment owned by a single entity - vulnerable to inside threats and logic bombs






26. A TCP version of ping - sends custom TCP packets to a host and listens for replies - enables port scanning and spoofing simultaneously






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






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






29. Netmasks or subnets provide a method for identifying what portion of an address is the network - and what portion is the host






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






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






32. 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.






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






34. 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






35. Syn - Syn/Ack - Ack






36. Most common approach - firewall - VPN - intrusion detection - AV - disk encryption - all parts of the organization receive equal protection - particularly vulnerable to malicious inside attacks






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






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






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






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






41. Improper deployment can increase attack risk - if production systems aren't sufficiently protected - they can be vulnerable from a honeypot - legal liability






42. 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.






43. 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






44. Confidentiality - integrity - availability






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






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






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