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






2. 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






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






4. Allows segmentation of a switch into different networks - regardless of where a system is plugged in - creates separate networks through software not hardware

5. 53 - DNS - 67 - BootP - 68 - BootP - 69 - TFTP - 123- NTP - 137-139 NBT - 161 - SNMP - 162 - SNMP - 2049 - NFS






6. 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






7. 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.






8. The Practice of sending an ACK inside another packet going to the same destination






9. 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






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






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






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






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






14. Weakness in a system - inherent in a complex system - majority are due to poor coding - gateway by which threats are manifested






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






16. 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






17. Used by IDS for a baseline before analysis - attackers will try to de-normalize traffic to evade detection - IDS will normalize data for understood protocols






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






19. The practice of sending an ACK inside another packet going to the same destination






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






21. 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






22. 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






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






24. Most common approach - firewall - VPN - intrusion detection - AV - disk encryption - all parts of the organization receive equal protection - particularly vulnerable to malicious inside attacks






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






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






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






28. 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






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






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






31. Network scanner.






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






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






34. 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






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






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






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. Stateful firewalls maintain state of traffic flows






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






40. A cracking tool inserted into the OS that allows the attacker to do as they please.






41. OSI






42. 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






43. 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
