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. 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.






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






3. 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.






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






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






6. Considered to be a perimeter device






7. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






8. 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






9. 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






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






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






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






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






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






15. Multiple levels of protection must be deployed - an exercie in detection - measures must be across a wide range of controls - compromises happen when people leave sites - risk - CIA triad - strategies






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






17. 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






18. 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






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






20. 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






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






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






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






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






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






26. FIN 130 - ACK 131 - FIN 570 - ACK 571






27. logic bomb - trojan horse - trap door






28. A cracking tool inserted into the OS that allows the attacker to do as they please.






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






30. 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






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






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






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






34. 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






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






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






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






38. 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






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






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






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






42. 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






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






44. 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






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






46. Going around with equipment to detect wireless networks






47. Message in its encrypted form






48. 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






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