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






3. Infects MBR - no network spreading potential






4. Good for multimedia - can use small single packets - multicasting is required - speed is the highest priority






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






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






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






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






9. 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






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






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






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






13. 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.






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






15. 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






16. Confidentiality - symmetric encryption






17. 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






18. 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






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






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






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






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

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






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






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






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






27. Strips OS commands and characters from input - avoid making system calls from within the app * especially based on user input






28. 1. physical 2. data 3. network 4. transport 5. session 6. presentation 7. application






29. Infects the EXE and make them operate slightly different - when infected - exe header sizes are altered to point to the appended viral code






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






31. rules indicate criteria in packets that represent events of interest - rules are applied to packets as they are received - alerts are created when matches are found






32. An FTP that allows downloads only if the user knows the exact name of the file they're looking for






33. 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






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






35. Network scanner.






36. True positive - false positive - true negative - false negative






37. Malware - insider threat - natural disaster - terrorism - pandemic






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






39. 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






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






41. 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






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






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






44. 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






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






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






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






48. 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






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






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