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






2. Infects MBR - no network spreading potential






3. risk = threat x vulnerability - impossible to eliminate - security is an exercise in loss reduction






4. Going around with equipment to detect wireless networks






5. 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






6. Relies on executable code insertion and user interaction to spread






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






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






9. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






10. Considered to be a perimeter device






11. A sends a SYN packet to B - B acknowledges with a SYN/ACK - A replies with ACK






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






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






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






15. 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






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






17. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






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






19. 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






20. 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






21. 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






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






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






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






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






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






27. 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






28. 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






29. Strips OS commands and characters from input - avoid making system calls from within the app * especially based on user input






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






31. Network scanner.






32. A low end firewall that can quickly be deployed using existing hardware. They examine packets themselves with no content.






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






34. Allows admins to remotely access a system for troubleshooting. - E.g VNC - GoToMyPc - PC Anywhere






35. 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






36. 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






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






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






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






40. Small program triggered by an event that provides an action. E.g. scheduled file removal if countdown isn't reset - ie: employee was fired






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






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






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






44. Known - unknown - zero day






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






46. Connection oriented - before systems can communicate over an ATM network - they must establish a virtual circuit between each other - this can span across multiple ATM switches that also handle communications for other systems - at the end of the con






47. Confidentiality - integrity - availability






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






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






50. One is for talking - one is for implementing
