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






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






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






4. 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






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






6. Message in its encrypted form






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

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






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






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






11. 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






12. 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






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






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






15. Uses a 1 to 1 substitution of characters - rotate the alphabet by 'n' number of characters - rot+X means rotate the letters X characters






16. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






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






18. Unencrypted message in its original form






19. Replicates traffic onto all ports - no traffic monitoring - cannot control which ports should or shouldn't receive frames - forming a large collision domain.






20. 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






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






22. Considered to be a perimeter device






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






24. Switches networks make it difficult to monitor traffic in promiscuous mode - topology must be able to support traffic aggregation for monitoring






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






26. Uses inclusive or exclusive lists - inclusive analysis utilizes a list of keywords - exclusive analysis utilizes a list of events that can be ignored






27. 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.






28. Wide Area Network - Larger than MAN or LAN - uses public network - phone lines - and leased lines to tie LAN and MAN over a dispersed area






29. Improper deployment can increase attack risk - if production systems aren't sufficiently protected - they can be vulnerable from a honeypot - legal liability






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






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






32. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






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






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






35. 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






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






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






38. Going around with equipment to detect wireless networks






39. OSI






40. 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






41. 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






42. Confidentiality - integrity - availability






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






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






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






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






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






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






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