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






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






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






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






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






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






7. Very simplistic. All systems are attached to the same cable segment. Rarely used because they're unreliable - low fault tolerance - poor traffic isolation - with limited scalability






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






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






10. Going around with equipment to detect wireless networks






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






12. 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






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






14. Confidentiality - symmetric encryption






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






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






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






18. 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






19. Message in its encrypted form






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






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






22. 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






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






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






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






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






27. 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






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






29. Stateful firewalls maintain state of traffic flows






30. 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






31. 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






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






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






34. logic bomb - trojan horse - trap door






35. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






36. 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






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






38. -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






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






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






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






42. 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


43. Isolates systems when they initially connect to the network - allows systems to be scanned and checked prior to being put on a trusted segment






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






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






46. fast - with little fidelity - examines header information and limited payload data






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






48. Provides insight into the tactics - motives - and attacker tools






49. 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


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