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. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






2. 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






3. Uses flow control to handle network congestion - can send larger amounts of data per packet - has guaranteed delivery of transmitted data - better protection against spoofing - reduces need for error checking at higher OSI layers






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






5. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






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






7. 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.






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






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






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






11. 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






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






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






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






15. Personal area network - phone tethering - bluetooth - etc






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






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






18. 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






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






20. Uses a 1 to 1 substitution of arbitrary numbers - given a one character mapping - you cannot determine the key






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






22. 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.






23. Used for connecting two physical segments of a network - segments traffic - breaks up collision domains - not generally used because of switches






24. OSI






25. deployment challenges including topology and access limitations - analyzing encrypted traffic - quantity vs. quality of signatures - performance limitations with extensive analysis techniques - very costly for proper management






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






27. Known - unknown - zero day






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






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






30. 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






31. 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






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






33. keeps the same letters - but changes the position within the text - easy to break - can be combined with substitution






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






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






36. A sends a SYN packet to B - B acknowledges with a SYN/ACK - A replies with ACK






37. 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






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






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






40. open source tool for monitoring - can be used as a NIDS - has quick updates and flexibility for custom rules






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






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






43. 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






44. Confidentiality - integrity - availability






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






46. Going around with equipment to detect wireless networks






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






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






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






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