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






2. Simplest form of a research honeypot - useful in identifying nature of TCP scans - allows attacker to complete 3-way handshake - listens on a defined port - logs incoming requests for analysis






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






4. Going around with equipment to detect wireless networks






5. logic bomb - trojan horse - trap door






6. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






7. Confidentiality - integrity - availability






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






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






10. Identify critical assets and provide layered protection - data is accessed by applications - applications reside on hosts - hosts operate on networks






11. Network scanner.






12. A hash is produced when applied to a monitored file. The hash always generates the same value unless a change was made. HIDS software checks the hashes of monitored files and if a change is found - analyst is notified. - ie: tripwire






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






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






15. 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






16. 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






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






18. 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






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






21. Syn - Syn/Ack - Ack






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






23. 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






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






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






26. 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






27. Stateful firewalls maintain state of traffic flows






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






29. 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






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






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






32. Bits of code embedded in programs to quickly gain access at a later time






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






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






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






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






37. 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






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






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






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






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






42. A low end firewall that can quickly be deployed using existing hardware. They examine packets themselves with no content.






43. Considered to be a perimeter device






44. risk = threat x vulnerability - impossible to eliminate - security is an exercise in loss reduction






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






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






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






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

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






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