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. Metropolitan area network - spans across city or town - larger than a LAN - uses fiber for backbone






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






3. 53 - DNS - 67 - BootP - 68 - BootP - 69 - TFTP - 123- NTP - 137-139 NBT - 161 - SNMP - 162 - SNMP - 2049 - NFS






4. 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






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






6. Going around with equipment to detect wireless networks






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






8. Confidentiality - symmetric encryption






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






10. 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






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






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






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






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






15. 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






16. The practice of sending an ACK inside another packet going to the same destination






17. One is for talking - one is for implementing






18. 53 bytes - 48 bytes for data - 5 bytes for the header






19. -Malicious code might execute destructive overwrite to hard disks -Malicious mas mailing code might expose sensitive information to the internet - web server compromise might expose organization to ridicule - Web server compromise might expose custom






20. Confidentiality - integrity - availability






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






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






23. Spread as an office attachment with executable code programmed using macro facility - targets are data files - visual basic editor and other macro languages - payload executes when the code is launched






24. Infected millions through various methods - vulnerability in the MS Server Service - brute force admin password through network shares - infect removable devices with a malicious autorun script






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






26. Considered to be a perimeter device






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






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






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






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






31. OSI






32. rules indicate criteria in packets that represent events of interest - rules are applied to packets as they are received - alerts are created when matches are found






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






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






35. Message in its encrypted form






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






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. 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






39. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






40. keeps the same letters - but changes the position within the text - easy to break - can be combined with substitution






41. 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






42. 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






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






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






45. An FTP that allows downloads only if the user knows the exact name of the file they're looking for






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






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






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






49. TCP/IP - the IP protoco - The core routing protocol of the internet - - deals with transmission of packets between end points - defines the addressing scheme for the internet






50. 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
