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






2. Take control of a session between a server and client - the users gets kicked off the session while the attacker inserts himself into the session by sending a reset request to the client






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






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






5. A logical group of computers connected via a switch/hub that share the same network prefix in their IP address






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






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






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






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






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






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






12. Collection on honeypots






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






14. A set of rules computers use to communicate with each other across a network






15. Acts as an organizations internal phone system






16. Head of a packet contains...






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






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






19. Generate random TCP sequence numbers and encrypt traffic countermeasure what attacks






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






21. Bbenign activity reported as malicious






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






23. 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






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






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






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






27. Packet filtering - proxies - stateful inspection






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






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






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






31. IDS response method using logging and notification






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






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






34. 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






35. A variation of a smurf attack using UDP






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






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






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






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






40. Level 2 firewall often used to filter web traffic






41. Session hijacking countermeasure






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






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






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






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






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






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






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






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






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