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. Uniform protection - protected enclaves - information centric - threat vector analysis






2. Free linux WLAN analysis tool - completely passive - cannot be detected - supports advanced GPS integration and mapping features - used for wardriving - WLAN vulerability assessment






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






4. 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






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






6. 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






7. local area network - small network confined to small location - all equipment owned by a single entity - vulnerable to inside threats and logic bombs






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






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






10. 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






11. A list of files is defined that should be monitored for a change - HIDS software calculates a one-way hash for each file - if a change is made to the file - the hash is changed






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


13. 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.






14. 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






15. It handles the establishment and maintenance of connections between systems






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






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






18. 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






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






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






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






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






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






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






25. logic bomb - trojan horse - trap door






26. Common backdoor to open a port - port scan scans for open ports on remote host - scans 0 - 65 -535 twice. TCP and UDP






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






28. 53 bytes - 48 bytes for data - 5 bytes for the header






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






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






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






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






33. Message in its encrypted form






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






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






36. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






37. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






38. 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






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


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






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






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. Work groups that require additional protection are segmented from the rest of the internal organization - restricting access to critical segments - system of VPNs - internal firewall - VLANs and ACLs






44. OSI






45. Full open - half open (stealth scan) - UDP - Ping






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






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






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






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






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