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. 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






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






3. The practice of sending an ACK inside another packet going to the same destination






4. 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






5. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






6. 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






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. 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.






9. Resource exhaustion like DDoS or fork attack - unexpected input value the machine does not know how to process






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






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






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






13. Known - unknown - zero day






14. 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






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






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






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






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






19. 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






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






21. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






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






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






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






25. An agreement on how different computer will work - protocols define the format and order of messages and what to do upon receipt of the messages - basically the rules of the network






26. True positive - false positive - true negative - false negative






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






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






29. 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






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






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






32. Network scanner.






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






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






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






36. Infects MBR - no network spreading potential






37. logic bomb - trojan horse - trap door






38. 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






39. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






40. Stateful firewalls maintain state of traffic flows






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






42. Unencrypted message in its original form






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






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






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






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






47. Connects the physical part of the network (cables) with the abstract (packets and datastreams)






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






49. Going around with equipment to detect wireless networks






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