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






2. Threat requires a vector to cross the vulnerability - stop the ability of the threat to use the vector






3. Simple attack done by simply browsing available information that's allowed on a local network.






4. 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






5. 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






6. Application layer attacks may get through - dialup - VPN - extranet connections may bypass firewalls






7. Uses a 1 to 1 substitution of arbitrary numbers - given a one character mapping - you cannot determine the key






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






9. 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






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






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






12. logic bomb - trojan horse - trap door






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






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






15. Infects the EXE and make them operate slightly different - when infected - exe header sizes are altered to point to the appended viral code






16. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






17. 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






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






19. An attacker spoofs the victim's IP and sends an ICMP ECHO request to the broadcast address of a network. When every system responds - a DoS occurs.






20. ATM supports two types of virtual circuits: permanent virtual circuits and switches virtual circuit - PVC is set up in advance - usually manually - SVC is established automatically through a signaling protocol and can be created on the fly - establis






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






22. Unencrypted message in its original form






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






24. A sends a SYN packet to B - B acknowledges with a SYN/ACK - A replies with ACK






25. 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






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






27. Wide Area Network - Larger than MAN or LAN - uses public network - phone lines - and leased lines to tie LAN and MAN over a dispersed area






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






29. War dialing - war driving - Sniffing - eavesdropping - dumpster diving - social engineering






30. 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






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






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






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






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






35. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






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






37. 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






38. 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






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






40. Migrate to WPA2 - use strong authentication like PEAP or TTLS - audit network installations - require mutual auth between client and infrastructure equipment






41. Infects MBR - no network spreading potential






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






43. 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






44. Trivial File Transfer Protocol - method to transfer files from one device to another without needing authentication






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






47. 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






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






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






50. 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.
