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






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






4. Most commonly used transport protocol today - ensures reliable packet delivery - has error handling built in






5. logic bomb - trojan horse - trap door






6. One is for talking - one is for implementing






7. 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






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






9. 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






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






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






12. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






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






14. 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.






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






16. 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






17. Unencrypted message in its original form






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






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






20. 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






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






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






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






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






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






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






27. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






28. Message in its encrypted form






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






30. 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.






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






32. Attacks systems through known vulnerabilities - automatically scans for more systems to attack - lowers system defenses - installs rootkit or root shell - opens up back doors - self contained malware that can copy itself






33. 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






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






35. 53 - DNS - 67 - BootP - 68 - BootP - 69 - TFTP - 123- NTP - 137-139 NBT - 161 - SNMP - 162 - SNMP - 2049 - NFS






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






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






38. 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






39. 1. physical 2. data 3. network 4. transport 5. session 6. presentation 7. application






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






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






42. 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






43. 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






44. 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






45. 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






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






47. Take the file and try to compress it. If it compresses - it means there is a pattern and it's more easily crackable

48. 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






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






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