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






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






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






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






5. keeps the same letters - but changes the position within the text - easy to break - can be combined with substitution






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






7. One is for talking - one is for implementing






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






9. True positive - false positive - true negative - false negative






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






11. 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






12. Message in its encrypted form






13. 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






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






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






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






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






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






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






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






21. 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






22. 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






23. 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.






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






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






26. 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






27. Connection oriented - before systems can communicate over an ATM network - they must establish a virtual circuit between each other - this can span across multiple ATM switches that also handle communications for other systems - at the end of the con






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

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






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






31. logic bomb - trojan horse - trap door






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






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






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






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






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






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






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






39. Stateful firewalls maintain state of traffic flows






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






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






42. 53 - DNS - 67 - BootP - 68 - BootP - 69 - TFTP - 123- NTP - 137-139 NBT - 161 - SNMP - 162 - SNMP - 2049 - NFS






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






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






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






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






47. 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






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






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






50. Anonymous FTP - FTP passes through clear text - Bounce attacks with the PORT command - user can cause an FTP to open a connection from the FTP's own commands and bypass a firewall
