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






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






3. 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






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






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






6. Acts as an organizations internal phone system






7. 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






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






9. Used to pass data from one VLAN to another






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






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






12. IDS response method using logging and notification






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






14. Connects two or more subnets - determines the best path to forward packets based on packet header and forwarding table information






15. Dynamic / private ports






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






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






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






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






20. Twisted pair cable with speed capability of 10Mbps






21. Firewall with several NICs connected to different networks






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






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






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






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






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






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






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






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






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






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






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






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






34. 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






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






36. A level 3 firewall that remembers / tracks network connections - maintains a state table - distinguish which side of a firewall a connection was initiated - higher security






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






38. User / registered ports






39. 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






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






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






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






44. Protocol used to map an known IP address to its corresponding media access control (MAC) address






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






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






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






48. 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






49. 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






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