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






2. 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






3. Known - unknown - zero day






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






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






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






7. 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






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






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






10. Syn - Syn/Ack - Ack






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






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






13. 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






14. 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






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






16. True positive - false positive - true negative - false negative






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






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






20. It interacts with the application layer to determine which network services will be required






21. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






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






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






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






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






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






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






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






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






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






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






32. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






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






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






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






36. Trying to ID modems in a telephone exchange that may be susceptible to compromise






37. Confidentiality - integrity - availability






38. Simple attack done by simply browsing available information that's allowed on a local network.






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






40. 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






41. Unencrypted message in its original form






42. 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






43. 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






44. Network scanner.






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