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






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






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






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






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






7. User / registered ports






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






9. Acts as an organizations internal phone system






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






11. Collection on honeypots






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






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






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






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






16. A sniffer mode used to capture traffic addressed to/from another machine on the network






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






18. A variation of a smurf attack using UDP






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






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






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






22. Level 2 firewall often used to filter web traffic






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






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






25. A logical division of a computer network - in which all nodes can reach each other by broadcast at the data link layer - equivalent to a VLAN






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






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






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






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






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






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






32. 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






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






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






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






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






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






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






39. Twisted pair cable with speed capability of 1Gbps






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






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






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






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






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






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






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






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






48. Monitors network traffic to identify possible attacks






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






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