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. 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






2. 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






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






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






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






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






7. 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






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






9. 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






10. size is whatever the length of the UDP portion of the packet. Could be as large as 65 -535






11. 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






12. 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






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






14. 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






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






16. Confidentiality - integrity - availability






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






18. Unencrypted message in its original form






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






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






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






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






23. 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






24. 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






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






26. True positive - false positive - true negative - false negative






27. OSI






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






29. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






30. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






31. Syn - Syn/Ack - Ack






32. Going around with equipment to detect wireless networks






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






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






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






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






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

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


38. destruction of data - leaking confidential information - providing backdoor access






39. 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






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






41. 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






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






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






44. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






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






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






47. 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






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






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






50. Attempt to manipulate or trick a person into providing information or access - bypass network security by exploiting humans - vector is often outside attack by telephone or visitor inside
