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. 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






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






3. 53 bytes - 48 bytes for data - 5 bytes for the header






4. Network scanner.






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






6. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






7. Message in its encrypted form






8. Confidentiality - integrity - availability






9. 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






10. Good for multimedia - can use small single packets - multicasting is required - speed is the highest priority






11. 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






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






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






14. Infects MBR - no network spreading potential






15. 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






16. Uses a 1 to 1 substitution of characters - rotate the alphabet by 'n' number of characters - rot+X means rotate the letters X characters






17. 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






18. logic bomb - trojan horse - trap door






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






20. Going around with equipment to detect wireless networks






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






22. Confidentiality - symmetric encryption






23. 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






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






25. It interacts with data and prepares it to be transmitted across the network. It ensures reliable connectivity from end-to-end






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






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






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






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






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






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






32. 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






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






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 it's corresponding IP address






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






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






37. A system resource that has no legitimate purpose or reason for someone to connect to it - its purpose is to draw in attackers to understand how they break into a system






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






39. Considered to be a perimeter device






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






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






42. Protects internal/external systems from attack - filters communications based on content - performs NAT - encrypts communications for VPN - logging to aid in intrusion detection






43. 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






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






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






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






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






48. Poor programming without error checking can allow commands to be run in an input field. This can point to a command further in the buffer that will execute the attacker's payload.






49. Outside attack from network - Outsider attack from telephone - Insider attack from local network - insider attack from local system - attack from malicious code






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