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






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






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






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






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






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






7. 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






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






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






10. Promiscuous NIC to sniff passing traffic - admin NIC to send alerts to centralized management system






11. 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






12. Twisted pair cable with speed capability of 1Gbps






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






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






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






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






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






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






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






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






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






22. Session hijacking countermeasure






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






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






25. User / registered ports






26. Level 2 firewall often used to filter web traffic






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






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






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






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






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






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






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






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






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






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






37. 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






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






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






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






41. Monitors network traffic to identify possible attacks






42. A variation of a smurf attack using UDP






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






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






45. Bbenign activity reported as malicious






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






47. Head of a packet contains...






48. Acts as an organizations internal phone system






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






50. Collection on honeypots
