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






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






4. 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






5. Dynamic / private ports






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






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






8. IDS response method using logging and notification






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






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






11. Twisted pair cable with speed capability of 1Gbps






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






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






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






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






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






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






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






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






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






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






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






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






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






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






27. 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






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






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






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






31. 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






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






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






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






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






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






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






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






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






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






41. Attack where an attacker intercepts traffic and tricks parties at either end into believing they are communicating with each other






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






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






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






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






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






47. Malicious activity not reported or detected






48. 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






49. Level 2 firewall often used to filter web traffic






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