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






2. 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






3. Dynamic / private ports






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






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






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






7. Used to pass data from one VLAN to another






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






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






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






12. Firewall with several NICs connected to different networks






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






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






15. Twisted pair cable with speed capability of 10Mbps






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






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






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






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






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






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






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






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






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






25. IDS response method using logging and notification






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






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






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






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






33. 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






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






35. Collection on honeypots






36. IDS that relies on usage patterns and baseline operation - can ID new vulnerability - high rate of false alarms






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






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






39. Head of a packet contains...






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






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






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






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






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






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






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






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






48. Acts as an organizations internal phone system






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






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