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. 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






2. 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.






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






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






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






6. 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






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






8. Unencrypted message in its original form






9. A cracking tool inserted into the OS that allows the attacker to do as they please.






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






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






13. 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






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






16. 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






17. 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






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






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






20. An FTP that allows downloads only if the user knows the exact name of the file they're looking for






21. 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.






22. Improper deployment can increase attack risk - if production systems aren't sufficiently protected - they can be vulnerable from a honeypot - legal liability






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






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






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






26. 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






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






28. 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






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






30. 53 bytes - 48 bytes for data - 5 bytes for the header






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






32. Confidentiality - integrity - availability






33. Network scanner.






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






35. Confidentiality - symmetric encryption






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






37. logic bomb - trojan horse - trap door






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






39. 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






40. Bits of code embedded in programs to quickly gain access at a later time






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






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






43. One is for talking - one is for implementing






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






45. 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






46. Message in its encrypted form






47. Relies on executable code insertion and user interaction to spread






48. Personal area network - phone tethering - bluetooth - etc






49. Network traffic to the host - typically listens on all interface - uses signature analysis to identify events of interest






50. packet filter firewalls rely on TCP flags to determine connection state. Attacker can send ACK packets only to bypass firewall.
