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






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






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






4. 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






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






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






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






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






9. 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






10. Unencrypted message in its original form






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






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






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






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






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






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






17. 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






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






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






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






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






22. OSI






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






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






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






26. Netmasks or subnets provide a method for identifying what portion of an address is the network - and what portion is the host






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






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






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






30. Message in its encrypted form






31. Confidentiality - integrity - availability






32. Connects many WANs - MANs - and LANs - provided via ISP






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






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






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






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






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






38. 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






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






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






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






42. Physical layer - Data link layer - Network Layer - Transport Layer - Session Layer - Presentation Layer - Application Layer






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






44. Attempt to manipulate or trick a person into providing information or access - bypass network security by exploiting humans - vector is often outside attack by telephone or visitor inside






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






46. logic bomb - trojan horse - trap door






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






48. Infected millions through various methods - vulnerability in the MS Server Service - brute force admin password through network shares - infect removable devices with a malicious autorun script






49. 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.






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