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






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






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






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






5. 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






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






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






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






9. Level 2 firewall often used to filter web traffic






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






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






12. Head of a packet contains...






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






14. User / registered ports






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






16. 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






17. Acts as an organizations internal phone system






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






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






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






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






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






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






24. 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






25. Packet filtering - proxies - stateful inspection






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






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






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






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






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






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






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






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






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






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






36. 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






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






38. Collection on honeypots






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






40. Crashing a computer by sending oversized packets (over 64 bytes) that it doesn't know how to handle






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






42. Dynamic / private ports






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






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






45. 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






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






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






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






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






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