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






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






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






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






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






7. Used to pass data from one VLAN to another






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






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






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






11. Firewall with several NICs connected to different networks






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






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






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






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






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






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






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






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






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






21. 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






22. 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






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






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






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






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






27. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






43. Session hijacking countermeasure






44. Packet filtering - proxies - stateful inspection






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






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






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






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






49. Acts as an organizations internal phone system






50. Twisted pair cable with speed capability of 1Gbps
