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. 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






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






3. 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






4. Considered to be a perimeter device






5. 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.






6. Program disguised as something helpful - only to perform actions the user did not intend. Opening ports - installing other programs - etc.






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






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






9. Confidentiality - integrity - availability






10. Known - unknown - zero day






11. 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






12. 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






13. Prepends to the beginning of the file and gains control when the first instruction of the infected COM file is executed - appending to the end - virus writes its payload to the end and inserts jump instruction as the first instruction - which execute






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






15. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






16. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






17. Going around with equipment to detect wireless networks






18. 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






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






20. Personal area network - phone tethering - bluetooth - etc






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






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






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






24. packet filter firewalls rely on TCP flags to determine connection state. Attacker can send ACK packets only to bypass firewall.






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






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






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






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






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






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






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






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






33. Stateful firewalls maintain state of traffic flows






34. 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






35. Switches networks make it difficult to monitor traffic in promiscuous mode - topology must be able to support traffic aggregation for monitoring






36. Relies on executable code insertion and user interaction to spread






37. Syn - Syn/Ack - Ack






38. Infects MBR - no network spreading potential






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






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






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






42. ATM supports two types of virtual circuits: permanent virtual circuits and switches virtual circuit - PVC is set up in advance - usually manually - SVC is established automatically through a signaling protocol and can be created on the fly - establis






43. Used by IDS for a baseline before analysis - attackers will try to de-normalize traffic to evade detection - IDS will normalize data for understood protocols






44. Maintains complete TCP connection state and sequencing through 2 connections - address translation built-in by virtue of second connection above






45. Most common approach - firewall - VPN - intrusion detection - AV - disk encryption - all parts of the organization receive equal protection - particularly vulnerable to malicious inside attacks






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






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






48. 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






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






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