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






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






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






4. 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






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






6. User / registered ports






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






8. One process on every system - use local system resources - detect attacks that NIDS misses - examine data after decrypted - can be OS specific - more expensive






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






10. Used to pass data from one VLAN to another






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






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






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






14. Head of a packet contains...






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






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






17. Malicious activity not reported or detected






18. Twisted pair cable with speed capability of 1Gbps






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






20. A variation of a smurf attack using UDP






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






22. Packet filtering - proxies - stateful inspection






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






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






25. Twisted pair cable with speed capability of 10Mbps






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






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






28. 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






29. 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






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






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






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






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






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






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






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






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






38. Firewall that communicates directly with a perimeter router and the internal network - 2 NICs - screens internal traffic






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






40. Collection on honeypots






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






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






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






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






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






46. Session hijacking countermeasure






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






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






49. Monitors network traffic to identify possible attacks






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