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. 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






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






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






5. 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






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






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






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






9. Considered to be a perimeter device






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






11. It allows the transport layer to detect when the UDP headers or the payload have been modified in transit






12. Unencrypted message in its original form






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






14. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






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






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






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






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






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






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






21. True positive - false positive - true negative - false negative






22. 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






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






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






25. Message in its encrypted form






26. OSI






27. Confidentiality - symmetric encryption






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






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






30. 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






31. 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






32. 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.






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






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






35. CIDR is a shorthand way of specifying which portion of the address is the network - and which portion is the host






36. logic bomb - trojan horse - trap door






37. Small program triggered by an event that provides an action. E.g. scheduled file removal if countdown isn't reset - ie: employee was fired






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


39. 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






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






41. 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






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






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






44. Provides insight into traffic on the network - help detect problems with network operations - provides auditing for other security measures






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






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






47. 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.






48. 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






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






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