Test your basic knowledge |

Comptia Security +: Network Security

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. Multiple network defense components are placed throughout the organizations assets and the network is properly segmented






2. Used to pass data from one VLAN to another






3. Unauthenticated connections - creating the potential for a successful connection as an anonymous user






4. Most common DMZ implementation using three firewall interfaces (internet - intranet - DMZ)






5. One device per network segment - does not use local system resources - can't examine encrypted traffic - OS independent - less expensive






6. A firewall that checks all layers of a packet including content - verifying an expected response to a current communication session - also call a deep packet inspection






7. A level 3 firewall that remembers / tracks network connections - maintains a state table - distinguish which side of a firewall a connection was initiated - higher security






8. IP spoofing attack where the attacker can monitor packets and participate in bidirectional communication






9. Ping flooding - ping of death - smurf - fraggle - SYN flood - land - teardrop - email flood






10. User / registered ports






11. Man in the middle attack where the attacker captures the traffic and sends it to the original recipient without altering the intercepted data






12. Level 2 firewall often used to filter web traffic






13. Unauthenticated Windows session where an attacker can gather list of users - groups - machines - shares - user and host SID






14. A complete transfer of all DNS zone information from one server to another






15. Examines content passing through and makes a decision on the data based on a set of criteria - normal uses email filtering and web browsing






16. Man in the middle attack where the content of an intercepted message is altered before it is sent on






17. IDS response method using logging and notification






18. Firewall with two NICs - one internal and one external facing - NAT is often used with this firewall






19. IP spoofing attack where the attacker can only send packets and has to guess about replies






20. A physical or logical subnetwork that houses systems accessible to a larger untrusted network - usually the Internet - also known as DMZ






21. Level 1 firewall that looks at the head of a packet - (not content) - operates rapidly - application independent - either allow or deny packets






22. One process on every system - use local system resources - detect attacks that NIDS misses - examine data after decrypted - can be OS specific - more expensive






23. DMZ implementation using two firewalls with different rule sets for the DMZ and intranet






24. Known as thicknet - 10mbps - limited to 500 meters






25. Allows all traffic except traffic that is specifically denied - also known as permissive access






26. An attack where fragmented UDP packets with odd offset values are sent to the victim - when the OS attempts to rebuild the fragments they overwrite each other and cause confusion






27. A method - used by switches and email servers - of delivering messages which are temporarily held by an intermediary before being sent to their final destination






28. A flaw in TCP/IP to verify that a packet really comes from the addess indicated in the IP header leads to this attack






29. Head of a packet contains...






30. An attacker redirects traffic by falsifying the IP address requested by ARP request






31. Known as thinnet - 10mbps - limited to 185 meters






32. Web servers - FTP servers - DNS servers - mail servers should be located on the _____________






33. Variation of the SYN flood where SYN packets are spoofed to have the same source and destination IP address and port






34. Cable used most in networks - maximum speed 1Gbps - maximum length 100 meters - susceptible to tap






35. A packet filtering firewall works at this layer of the OSI model






36. When a hacker takes over a TCP session between two machines - also known as session hijacking - foiled by the use of encrypted sessions






37. IDS that relies on the identification of known attack signatures






38. Firewall with several NICs connected to different networks






39. Seeks to reduce the probability and/or impact of a specific risk below an acceptable threshold






40. Evolved from IDS - monitors network traffic - detects and responds to attack on network






41. A DoS attack that subverts the normal "three way handshake" of TCP/IP by sending SYN packets - but no corresponding ACK packets






42. Connects devices together to form a subnet - broadcasts incoming packets to all devices






43. IDS that relies on usage patterns and baseline operation - can ID new vulnerability - high rate of false alarms






44. An attack where an attacker captures sensitive information and sends it again later in an attempt to replicate the transaction






45. Cable designed for transmission at higher speeds (100Mbps - 2Gbps) and longer distances (2km) - expensive -eliminates signal tapping






46. Capture and analyze network traffic - also known as packet analyzer - sniffer - network analyzer






47. Firewall that communicates directly with a perimeter router and the internal network - 2 NICs - screens internal traffic






48. Malicious activity not reported or detected






49. IP - email - website - DNS - and ARP






50. Creating a illegitimate website with the intention of convincing victims that they are visiting a legitimate site - typically to collect confidential information
