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. Collection on honeypots






2. Connects devices together to form a subnet - packet forwarding is based on MAC addresses - works at the data link layer of the OSI






3. Level 2 firewall often used to filter web traffic






4. Protocol used to map an known IP address to its corresponding media access control (MAC) address






5. Twisted pair cable with speed capability of 10Mbps






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






7. Forging an IP address with the address of a trusted host






8. Session hijacking countermeasure






9. Attempt to block service or reduce activity by overloading the victim machine with ping requests






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






11. Packets with a forged source IP address - purpose to conceal the identity of the sender or impersonate another computing system






12. Twisted pair cable with speed capability of 1Gbps






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






14. Cable with copper core - has no physical transmission security and is easy to tap - 10mbps - maximum length 500 meters






15. Firewall with several NICs connected to different networks






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






17. A group of hosts on logical network segment that communicate as if they were attached to the same broadcast domain - regardless of their physical location






18. Monitors network traffic to identify possible attacks






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






20. Network configuration that permits selected outsiders access internal information systems






21. Amplifies the signal of incoming packets before broadcasting them to the network






22. 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






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






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






25. 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






26. Used by ISPs - single public network IP address is shared among many hosts on a private network - also known as PAT






27. Blocks all traffic from passing through the firewall except for traffic that is explicitly allowed - also known as restrictive access - best practice






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






29. An application layer gateway works at this layer of the OSI model






30. Attack where an attacker intercepts traffic and tricks parties at either end into believing they are communicating with each other






31. Head of a packet contains...






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






33. One private IP address is mapped to one public IP address






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






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






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






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






38. 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






39. Malicious activity not reported or detected






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






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






42. A server that sits between an intranet and it's Internet connection - masking all IP addresses






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






44. Connects two or more subnets - determines the best path to forward packets based on packet header and forwarding table information






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






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






47. A pool of public IP addresses is shared by a collection of private IP addresses






48. A decoy system - intentionally left exposed to attract/distract attackers - logs and monitors attacker activities






49. A logical connection point allowing computers and software to communicate and exchange data






50. Used to pass data from one VLAN to another
