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






2. OSI






3. fast - with little fidelity - examines header information and limited payload data






4. 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






5. A spoofed IP is used to send a SYN to the target. It then responds with a SYN/ACK that never receives the final ACK to complete the handshake. This occupies a portion of the target's pre-established buffer for TCP and can prevent the target from acce






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






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






8. Uniform protection - protected enclaves - information centric - threat vector analysis






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






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






11. A time of check/time of use attack that exploits the difference in between when a security control was applied and the time the service was used.






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






13. One is for talking - one is for implementing






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






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






16. Allows segmentation of a switch into different networks - regardless of where a system is plugged in - creates separate networks through software not hardware

17. packet filter firewalls rely on TCP flags to determine connection state. Attacker can send ACK packets only to bypass firewall.






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






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






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






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






22. 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






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






24. Infects MBR - no network spreading potential






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






26. Very simplistic. All systems are attached to the same cable segment. Rarely used because they're unreliable - low fault tolerance - poor traffic isolation - with limited scalability






27. Network scanner.






28. 53 bytes - 48 bytes for data - 5 bytes for the header






29. 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






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






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






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






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






34. Stateful firewalls maintain state of traffic flows






35. 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






36. Poor programming without error checking can allow commands to be run in an input field. This can point to a command further in the buffer that will execute the attacker's payload.






37. 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






38. 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






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






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






41. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






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






43. Network traffic to the host - typically listens on all interface - uses signature analysis to identify events of interest






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






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






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






47. Common backdoor to open a port - port scan scans for open ports on remote host - scans 0 - 65 -535 twice. TCP and UDP






48. 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






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






50. 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
