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






2. Level 2 firewall often used to filter web traffic






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






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






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






6. 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






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






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






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






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






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






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






13. Dynamic / private ports






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






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






16. Collection on honeypots






17. IDS response method using logging and notification






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






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






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






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






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






23. Acts as an organizations internal phone system






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






25. Blocks all traffic from passing through the firewall except for traffic that is explicitly allowed - also known as restrictive access - best practice






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






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






28. 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






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






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






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






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






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






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






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






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






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






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






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






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






41. Twisted pair cable with speed capability of 1Gbps






42. Twisted pair cable with speed capability of 10Mbps






43. User / registered ports






44. Monitors network traffic to identify possible attacks






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






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






47. 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






48. IPS response method - terminate process/session - block/reject and redirect network traffic






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






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