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. 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.






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






3. 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






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






5. 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






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






7. 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






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






9. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






10. 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






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






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






13. Confidentiality - integrity - availability






14. 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






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






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






17. 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 its corresponding IP address






18. 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.






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






20. Network scanner.






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






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






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






24. Infects MBR - no network spreading potential






25. Simplest form of a research honeypot - useful in identifying nature of TCP scans - allows attacker to complete 3-way handshake - listens on a defined port - logs incoming requests for analysis






26. OSI






27. Weakness in a system - inherent in a complex system - majority are due to poor coding - gateway by which threats are manifested






28. -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






29. 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






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






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






32. 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






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






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






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






36. One is for talking - one is for implementing






37. An attacker spoofs the victim's IP and sends an ICMP ECHO request to the broadcast address of a network. When every system responds - a DoS occurs.






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






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






40. Application layer attacks may get through - dialup - VPN - extranet connections may bypass firewalls






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






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






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






44. Known - unknown - zero day






45. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






46. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






47. Considered to be a perimeter device






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






49. 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






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