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






2. Bbenign activity reported as malicious






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






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






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






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






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






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






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






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






11. 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






12. 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






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






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






15. Twisted pair cable with speed capability of 10Mbps






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






17. Packet filtering - proxies - stateful inspection






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






19. A pool of public IP addresses is shared by a collection of private IP addresses






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






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






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






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






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






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






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






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






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






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






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






31. 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






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






33. Collection on honeypots






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






35. A DoS attack that subverts the normal "three way handshake" of TCP/IP by sending SYN packets - but no corresponding ACK packets






36. Twisted pair cable with speed capability of 1Gbps






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






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






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






40. User / registered ports






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






42. A variation of a smurf attack using UDP






43. Acts as an organizations internal phone system






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






45. 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






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






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






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






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






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