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






2. 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






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






5. -Malicious code might execute destructive overwrite to hard disks -Malicious mas mailing code might expose sensitive information to the internet - web server compromise might expose organization to ridicule - Web server compromise might expose custom






6. logic bomb - trojan horse - trap door






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






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






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






10. 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






11. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






12. 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.






13. Infects MBR - no network spreading potential






14. CIDR is a shorthand way of specifying which portion of the address is the network - and which portion is the host






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






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






17. True positive - false positive - true negative - false negative






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






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






20. 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






21. An attacker recruits zombie systems ahead of time to simultaneously release a flood of traffic at a specific target.






22. 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






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






24. Common backdoor to open a port - port scan scans for open ports on remote host - scans 0 - 65 -535 twice. TCP and UDP






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






26. 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






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






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






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






30. 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.






31. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






32. Going around with equipment to detect wireless networks






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






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






35. Connects many WANs - MANs - and LANs - provided via ISP






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






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






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






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






40. 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






41. Confidentiality - integrity - availability






42. 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






43. Message in its encrypted form






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






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






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






47. Confidentiality - symmetric encryption






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






49. A list of files is defined that should be monitored for a change - HIDS software calculates a one-way hash for each file - if a change is made to the file - the hash is changed






50. 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
