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






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






3. 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






4. 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






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






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






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






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






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






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






11. 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






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






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






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






15. 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






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






17. 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






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






19. Known - unknown - zero day






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






21. 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






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






23. Allows admins to remotely access a system for troubleshooting. - E.g VNC - GoToMyPc - PC Anywhere






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

25. Going around with equipment to detect wireless networks






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






27. 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






28. 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






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






30. An attempt to gain access by bombarding it with guesses until the password is found.






31. True positive - false positive - true negative - false negative






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






33. 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






34. Syn - Syn/Ack - Ack






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

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






37. 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






38. 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.






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






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






41. 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






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






43. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






44. 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






45. 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






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






47. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






48. risk = threat x vulnerability - impossible to eliminate - security is an exercise in loss reduction






49. 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






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