CISSP Telecom And Network Security

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. Protocol based on the first version - however this version allows for fixed bandwidth to be allocated for specific applications.






2. Blue tooth vulnerability where an attacker sends messages to a receiver that is in discovery mode.






3. Most commonly used LAN implementation today. Considered a "chatty" protocol because it allows all systems to hear each other's broadcasts. Has many collisions because all systems share the same medium. Can operate at 10 to 1000 Mbps.






4. Type of wireless authentication where the device does not need to provide a key for authentication. Usually - only the SSID is required and plaintext transmission occurs.






5. Problems: Central device is a single point of failure.






6. In the OSI layer 5 - these are the types of what?






7. Combines voice and data over the same IP network media and protocol. Reduces the cost of implementing and maintaining two different networks.






8. Most expensive type of WAN connection because the fee is based on distance between the two points rather than the amount of bandwidth used. Examples - T1 and T3.






9. Strengths of a type of firewall: Better security than packet filtering. Looks at all info in the packet - up to the application layer. Breaks the connection between trusted and untrusted systems. Weaknesses include limited number of applications supp






10. Protocol stack used instead of TCP/IP on wireless devices. The "gap" in this protocol involves translating its secure traffic to SSL or TLS - which is typically done by a 3rd party.






11. Type of wireless security standard that uses AES in CBC mode.






12. Communication devices that are not synchronized - meaning all devices can send data at will - send a sequence of bits framed with a start and stop bit.






13. Problems: Requires more expense in cabling and extra effort to track down cable faults.






14. Wireless communication that distributes individual signals across the allocated frequencies.






15. Wireless LAN standard that operates in a 2.4Ghz range - 11Mbps - DSSS






16. Altering an ARP table so an IP address is mapped to a different MAC address. Results in traffic being routed to an attacker's computer.






17. Firewall that does not require a proxy for each service; does not provide detailed access control; but does provide for a wider range of protocols.






18. Security wireless standard that rotates encryption keys - stronger IV values - MAC codes for packet integrity. Works in combination with WEP.






19. Dynamically builds ACL's to allow internal systems to communicate with external systems. Once the connection is finished - the ACL is removed from the list. 4th generation firewall.






20. A Temporary circuit set up for a single connection. Set up and torn down as they are needed.






21. Type of network that allows large IP ranges to be divided into smaller - logical - and easier to maintain network segments.






22. Faster because processing is done in the kernel. One network stack is created for each packet. 5th generation firewall - runs at the application layer.






23. Type of firewall that lies between the perimeter router and and LAN.






24. Type of LAN and MAN technology - usually used for backbones - that uses token-passing technology and has redundant rings in case the primary ring goes down.






25. Standard that addresses wireless MAN technologies.






26. Server that can be configured to hang up and call back remote users - but this can be compromise by enabling call forwarding.






27. OSI layer that prepares data for the network medium by framing it into LAN/WAN frames. Defines how the physical layer transmits the network packets. Protocols at this layer ARP (Address Resolution Protocol) - RARP (Reverse Address Resolution Protocol






28. VPN protocol that works at the data link layer - can only run in IP networks - and provides encryption and encapsulation. This is Microsoft's VPN solution.






29. In a token ring network - each computer is connected to this - which acts as a central hub.






30. Both directions - both applications can send information at a time. Session Layer Communication Modes






31. Wireless communication that splits total amount of bandwidth into smaller sub-channels. Send and receiver work in one of the channels for a period of time - and then move into a different channel. It uses a portion of the bandwidth - throughput of 1-






32. Protocol where all computers compete for the shard network cable - listen to learn when they can transmit data - susceptible to data collisions. Used by Ethernet.






33. Type of cable where STP and UTP (shielded and unshielded) cables are the most popular - cheapest - and easiest to work with. However - easiest to tap into - have cross talk issues - and are vulnerable to electromagnetic interference (EMI).






34. Type of cabling problem signals from one wire crossing over to another wire.






35. Protocol that addresses vulnerabilities found in PAP. Uses challenge/response mechanism to authenticate the user instead of sending password.






36. Type of cable that is more expensive than UTP and STP - more resistant to EMI - can carry baseband and board band technologies.






37. Works like a private line for a customer with an agreed upon bandwidth. Path is programmed into the WAN devices.






38. Type of ethernet implementation that uses twisted-pair copper wiring and transmits at 100Mbps.






39. 7: Application - 6: Presentation - 5: Session - 4: Transport - 3: Network - 2: Data Link - 1: Physical - Remember 'All People Seem To Need Data Processing'






40. Network segment name for a DMZ created by two physical firewalls.






41. Type of authentication protocol that provides a framework to enable may types of authentication techniques to be used during PPP connections. It extends the possibilities to one-time passwords - token cards - biometrics - Kerberos - and digital certi






42. OSI layer that sets up - maintains - and breaks down the dialog (session) between two applications. Controls dialog organization and synchronization. Protocols that work at this layer are NFS (Network File System) - SQL - NetBIOS - RPC.






43. Standard for transmitting data across the Internet. One is reliable and connection oriented. The other is unreliable and connectionless.






44. Type of network device that divides networks into more controllable segments to ensure more efficient use of bandwidth. Works at the data link layer and understands MAC addresses - not IP addresses.






45. Communication process that must deliver data with set time constraints. Applications are typically video related where audio and must match perfectly. VoIP is another example.






46. Type of firewall that is also know as a screening router and is accomplished by ACL's (Lines of text called rules). Traffic can be filtered by address - ports - and protocol types. 1st generation firewall - runs at the network layer.






47. Type of firewall that can be compromised if the OS does not have packet forwarding or routing turned off.






48. Type of wireless authentication where a shared WEP key is used to encrypt a nonce for authentication.






49. The well known values range from 0-1023. FTP runs on 20 and 21 - SMTP runs on 25 - TFTP runs on 69 - DNS runs on 53 - HTTP runs on 80 - HTTPS runs on 443 - SNMP runs on 161.






50. Strengths of a type of firewall: application independence - high performance - and scalability. Weaknesses include low security - no protection above the network layer.
