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






2. Confidentiality - integrity - availability






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






4. 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






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






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






7. Confidentiality - integrity - availability






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






9. Allows admins to remotely access a system for troubleshooting. - E.g VNC - GoToMyPc - PC Anywhere






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






11. 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






12. 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






13. logic bomb - trojan horse - trap door






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






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






16. 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






17. 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






18. 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






19. 53 - DNS - 67 - BootP - 68 - BootP - 69 - TFTP - 123- NTP - 137-139 NBT - 161 - SNMP - 162 - SNMP - 2049 - NFS






20. Identify critical assets and provide layered protection - data is accessed by applications - applications reside on hosts - hosts operate on networks






21. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






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






23. Syn - Syn/Ack - Ack






24. 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






25. Stateful firewalls maintain state of traffic flows






26. Slow - requires stateful data tracking - inspects all fields - including variable-length fields






27. Handles transmissions across the physical media like wires - fiber - etc






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

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






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






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






32. 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.






33. Considered to be a perimeter device






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






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






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






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






38. 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






39. Good for multimedia - can use small single packets - multicasting is required - speed is the highest priority






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






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






42. 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






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






44. Handles the network address scheme and connectivity of multiple network segments. It handles communication.






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






46. 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






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






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






49. 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.






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