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






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






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






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






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






6. One is for talking - one is for implementing






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






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






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






10. 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






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






12. Infects MBR - no network spreading potential






13. Syn - Syn/Ack - Ack






14. 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






15. 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






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

17. 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






18. -Malicious code might execute destructive overwrite to hard disks -Malicious mas mailing code might expose sensitive information to the internet - web server compromise might expose organization to ridicule - Web server compromise might expose custom






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






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






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






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






23. 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






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






25. Small program triggered by an event that provides an action. E.g. scheduled file removal if countdown isn't reset - ie: employee was fired






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






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






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






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






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






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






32. 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






33. 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






34. A spoofed IP is used to send a SYN to the target. It then responds with a SYN/ACK that never receives the final ACK to complete the handshake. This occupies a portion of the target's pre-established buffer for TCP and can prevent the target from acce






35. 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






36. Network scanner.






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






38. 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






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






40. NTP - BootP/DHCP - NFS file systems - SNMP - TFTP






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

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


42. Identify critical assets and provide layered protection - data is accessed by applications - applications reside on hosts - hosts operate on networks






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






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






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






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






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






48. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






49. Connects many WANs - MANs - and LANs - provided via ISP






50. 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
