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. One is for talking - one is for implementing






2. Known - unknown - zero day






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






4. Confidentiality - symmetric encryption






5. Slow - requires stateful data tracking - inspects all fields - including variable-length fields






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






8. 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






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






10. Syn - Syn/Ack - Ack






11. 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






12. Simple attack done by simply browsing available information that's allowed on a local network.






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






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






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






16. 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






17. Maintains complete TCP connection state and sequencing through 2 connections - address translation built-in by virtue of second connection above






18. 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






19. -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






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






21. 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.






22. 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.






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






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






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






26. removable media - email attachments - web browsing - social networking - network vulnerabilities - IM applications - p2p






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






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






29. 53 bytes - 48 bytes for data - 5 bytes for the header






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






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






32. When someone has compromised the integrity of data or a program. Allows attackers to create backdoors.






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






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






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






36. Message in its encrypted form






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






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






39. Going around with equipment to detect wireless networks






40. 1 and 2 - Voice/Low speed data - 3 - Voice/Data 10Mb - 4 - Voice/Data 16Mb - 5 - 5e - Voice/Data 100Mb to 1Gb - 6 - Standard for gigabit






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






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






43. Stateful firewalls maintain state of traffic flows






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






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






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






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






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






49. Uses flow control to handle network congestion - can send larger amounts of data per packet - has guaranteed delivery of transmitted data - better protection against spoofing - reduces need for error checking at higher OSI layers






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