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






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






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






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






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






6. Two authoritative sources for your domain namespace with differing contents depending on whether the query is internal or external






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






8. Firewall with several NICs connected to different networks






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






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






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






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






13. Bastion host - dual homed firewall - multi homed firewall - screened host - screened subnet






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






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






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






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






18. IPS response method - terminate process/session - block/reject and redirect network traffic






19. Used to pass data from one VLAN to another






20. User / registered ports






21. IDS response method using logging and notification






22. Head of a packet contains...






23. Examines a entire packet and determines action based on a complex set of rules






24. Session hijacking countermeasure






25. Acts as an organizations internal phone system






26. Packet filtering - proxies - stateful inspection






27. Malicious insiders - connections that bypass the firewall (i.e. IM) - encrypted traffic/tunneling - social engineering - physical access are missed by ___________






28. 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






29. A variation of a smurf attack using UDP






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






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






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






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






34. Dynamic / private ports






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






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






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






38. Bbenign activity reported as malicious






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






40. 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






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






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






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






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






45. Monitors network traffic to identify possible attacks






46. Well known ports - allow administrative access - used for network services - considered only ports allowed to transmit traffic thru a firewall






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






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






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






50. 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
