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






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






3. Infects MBR - no network spreading potential






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






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






6. Physical layer - Data link layer - Network Layer - Transport Layer - Session Layer - Presentation Layer - Application Layer






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






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






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






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






11. 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






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






14. Application layer attacks may get through - dialup - VPN - extranet connections may bypass firewalls






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






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






17. Going around with equipment to detect wireless networks






18. NTP - BootP/DHCP - NFS file systems - SNMP - TFTP






19. 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






20. 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






21. Hash Authentication - asymmetric - non repudiation - digital signature - hash + asymmetry






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






23. 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






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






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






26. 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






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






28. Confidentiality - integrity - availability






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






30. 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






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






32. 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.






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






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






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






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






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






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






39. Confidentiality - symmetric encryption






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






41. 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






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






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






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






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






46. flags anomalous conditions in traffic on the network - requires understanding on what is normal - bases good traffic as a baseline






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






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






49. 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.






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