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. An attacker redirects valid request to malicious sites by feeding a DNS server altered records which are retained in its cache






2. A person or program masquerades as another by presenting false information to gain an illegitimate advantage






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






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






5. A ping message is broadcast to an entire network with a spoofed source IP addess of the victim computer - flooding the victim computer with responses during this attack






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






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






8. 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






9. A feature of firewalls / routers that disguise the IP address of internal systems allowing connection to the Internet using one public address






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






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






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






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






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






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






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






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






18. Bbenign activity reported as malicious






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






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






21. Type of IP addresses not routed on the internet: 10.x.x.x - 172.16.x.x - 192.168.x.x






22. IDS response method using logging and notification






23. Used to pass data from one VLAN to another






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






25. Firewall that intercepts and inspects messages before delivering them - placed between trusted and untrusted networks - degrade network traffic - also know as application gateway






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






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






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






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






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






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






32. Twisted pair cable with speed capability of 1Gbps






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






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






35. Monitors network traffic to identify possible attacks






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






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






38. Acts as an organizations internal phone system






39. 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






40. 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






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






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






43. Malicious activity not reported or detected






44. 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






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






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






47. A locked down/hardened host on the public side of the firewall highly exposed to attacks (i.e. web server - email server)






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






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






50. Dynamic / private ports
