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. Personal area network - phone tethering - bluetooth - etc






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






4. 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.






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






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






7. Uses inclusive or exclusive lists - inclusive analysis utilizes a list of keywords - exclusive analysis utilizes a list of events that can be ignored






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

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






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






11. Network scanner.






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






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






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






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






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






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






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






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






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






21. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






22. 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






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






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






25. Infected millions through various methods - vulnerability in the MS Server Service - brute force admin password through network shares - infect removable devices with a malicious autorun script






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






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






28. Confidentiality - integrity - availability






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






30. Confidentiality - integrity - availability






31. 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






32. flags anomalous conditions in traffic on the network - requires understanding on what is normal - bases good traffic as a baseline






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






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






35. Uses a 1 to 1 substitution of characters - rotate the alphabet by 'n' number of characters - rot+X means rotate the letters X characters






36. Four layers - Network Layer - Internet Layer - Transport Layer - Application layer






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






38. Outside attack from network - Outsider attack from telephone - Insider attack from local network - insider attack from local system - attack from malicious code






39. Hash Authentication - asymmetric - non repudiation - digital signature - hash + asymmetry






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






41. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






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