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






2. 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






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






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






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






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






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






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






9. Metropolitan area network - spans across city or town - larger than a LAN - uses fiber for backbone






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






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






12. 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






13. Syn - Syn/Ack - Ack






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






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






16. 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






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






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






19. fast - with little fidelity - examines header information and limited payload data






20. True positive - false positive - true negative - false negative






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






22. 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.






23. A system resource that has no legitimate purpose or reason for someone to connect to it - its purpose is to draw in attackers to understand how they break into a system






24. Message in its encrypted form






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






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






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






28. 53 bytes - 48 bytes for data - 5 bytes for the header






29. 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






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






31. 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






32. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






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






34. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






35. 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






36. 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.






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






38. Protected at rest - protected in transit - secure the key






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






40. logic bomb - trojan horse - trap door






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






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






43. Going around with equipment to detect wireless networks






44. OSI






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






46. Known - unknown - zero day






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






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






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






50. 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
