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. Relies on executable code insertion and user interaction to spread






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






3. Going around with equipment to detect wireless networks






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






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






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






7. The Practice of sending an ACK inside another packet going to the same destination






8. 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






9. Confidentiality - symmetric encryption






10. size is whatever the length of the UDP portion of the packet. Could be as large as 65 -535






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






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






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






14. Very simplistic. All systems are attached to the same cable segment. Rarely used because they're unreliable - low fault tolerance - poor traffic isolation - with limited scalability






15. 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






16. 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






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






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






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






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






21. 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






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






23. Infects MBR - no network spreading potential






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






25. deployment challenges including topology and access limitations - analyzing encrypted traffic - quantity vs. quality of signatures - performance limitations with extensive analysis techniques - very costly for proper management






26. 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






27. 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






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






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






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






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






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






33. 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






34. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






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






36. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






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






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. Stateful firewalls maintain state of traffic flows






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






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






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






43. 53 bytes - 48 bytes for data - 5 bytes for the header






44. 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






45. 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.






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






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






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






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






50. Most commonly used transport protocol today - ensures reliable packet delivery - has error handling built in
