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






2. 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






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






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






5. 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






6. Unencrypted message in its original form






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






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






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






10. Personal area network - phone tethering - bluetooth - etc






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






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






13. 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






14. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






15. 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






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






17. Isolates systems when they initially connect to the network - allows systems to be scanned and checked prior to being put on a trusted segment






18. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






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






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






21. 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






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






23. Anonymous FTP - FTP passes through clear text - Bounce attacks with the PORT command - user can cause an FTP to open a connection from the FTP's own commands and bypass a firewall






24. It handles the establishment and maintenance of connections between systems






25. 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






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






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






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






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






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






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






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






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






34. 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






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






36. 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






37. 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






38. Uses flow control to handle network congestion - can send larger amounts of data per packet - has guaranteed delivery of transmitted data - better protection against spoofing - reduces need for error checking at higher OSI layers






39. Work groups that require additional protection are segmented from the rest of the internal organization - restricting access to critical segments - system of VPNs - internal firewall - VLANs and ACLs






40. 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






41. Common backdoor to open a port - port scan scans for open ports on remote host - scans 0 - 65 -535 twice. TCP and UDP






42. 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






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






44. Full open - half open (stealth scan) - UDP - Ping






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






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






47. Confidentiality - integrity - availability






48. Infects MBR - no network spreading potential






49. Confidentiality - symmetric encryption






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