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






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






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






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






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






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






7. Collection on honeypots






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






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






10. Bbenign activity reported as malicious






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






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






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






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






15. User / registered ports






16. Malicious activity not reported or detected






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






18. A group of hosts on logical network segment that communicate as if they were attached to the same broadcast domain - regardless of their physical location






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






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






21. 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






22. Twisted pair cable with speed capability of 1Gbps






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






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






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






26. 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






27. Twisted pair cable with speed capability of 10Mbps






28. Firewall with several NICs connected to different networks






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






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






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






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






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






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






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






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






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






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






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






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






41. 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






42. Multiple network defense components are placed throughout the organizations assets and the network is properly segmented






43. Monitors network traffic to identify possible attacks






44. Acts as an organizations internal phone system






45. IDS response method using logging and notification






46. Level 2 firewall often used to filter web traffic






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






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






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






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