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






2. destruction of data - leaking confidential information - providing backdoor access






3. Uses flow control to handle network congestion - can send larger amounts of data per packet - has guaranteed delivery of transmitted data - better protection against spoofing - reduces need for error checking at higher OSI layers






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






5. 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






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






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






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






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






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






11. NTP - BootP/DHCP - NFS file systems - SNMP - TFTP






12. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






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






14. 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






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






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






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






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






19. Connects the physical part of the network (cables) with the abstract (packets and datastreams)






20. 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






21. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






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






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






24. 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






25. Hash Authentication - asymmetric - non repudiation - digital signature - hash + asymmetry






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






27. Stateful firewalls maintain state of traffic flows






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






29. Confidentiality - symmetric encryption






30. Confidentiality - integrity - availability






31. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






32. 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.






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






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






35. 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






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






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






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






39. 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






40. OSI






41. 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.






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






43. Network scanner.






44. Simple attack done by simply browsing available information that's allowed on a local network.






45. Uses a 1 to 1 substitution of arbitrary numbers - given a one character mapping - you cannot determine the key






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






47. One is for talking - one is for implementing






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






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






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