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. 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.






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






3. A list of files is defined that should be monitored for a change - HIDS software calculates a one-way hash for each file - if a change is made to the file - the hash is changed






4. 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.






5. 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






6. 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






7. 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






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






9. 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






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






11. Infects the EXE and make them operate slightly different - when infected - exe header sizes are altered to point to the appended viral code






12. Confidentiality - symmetric encryption






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






14. 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






15. Parasitic malware - boot record infector - macro - COM/Script program infector - EXE program infector






16. 53 bytes - 48 bytes for data - 5 bytes for the header






17. War dialing - war driving - Sniffing - eavesdropping - dumpster diving - social engineering






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






19. An appliance that controls access between public internet and a companies private network - or between a PC NIC and the rest of the PC.






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






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






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






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






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






25. Malware - insider threat - natural disaster - terrorism - pandemic






26. When someone has compromised the integrity of data or a program. Allows attackers to create backdoors.






27. Simplest form of a research honeypot - useful in identifying nature of TCP scans - allows attacker to complete 3-way handshake - listens on a defined port - logs incoming requests for analysis






28. Wide Area Network - Larger than MAN or LAN - uses public network - phone lines - and leased lines to tie LAN and MAN over a dispersed area






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






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






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






32. Confidentiality - integrity - availability






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






34. 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






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






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






37. 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






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






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






40. Provides insight into traffic on the network - help detect problems with network operations - provides auditing for other security measures






41. Known - unknown - zero day






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






43. 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.






44. Message in its encrypted form






45. OSI






46. Prepends to the beginning of the file and gains control when the first instruction of the infected COM file is executed - appending to the end - virus writes its payload to the end and inserts jump instruction as the first instruction - which execute






47. Not a replacement for firewalls - hardening - strong policies - or other DiD methods - low maintenance - inexpensive






48. Infects MBR - no network spreading potential






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






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