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






2. Twisted pair cable with speed capability of 1Gbps






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






4. IDS response method using logging and notification






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






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






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






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






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






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






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






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






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






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






15. Dynamic / private ports






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






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






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






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






20. 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






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






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






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






24. Monitors network traffic to identify possible attacks






25. 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






26. Protocol used to map an known IP address to its corresponding media access control (MAC) address






27. Connects devices together to form a subnet - packet forwarding is based on MAC addresses - works at the data link layer of the OSI






28. Twisted pair cable with speed capability of 10Mbps






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






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






31. Collection on honeypots






32. Level 2 firewall often used to filter web traffic






33. Acts as an organizations internal phone system






34. A ping message is broadcast to an entire network with a spoofed source IP addess of the victim computer - flooding the victim computer with responses during this attack






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






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






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






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






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






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






41. 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






42. Two authoritative sources for your domain namespace with differing contents depending on whether the query is internal or external






43. Used to pass data from one VLAN to another






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






45. Firewall with several NICs connected to different networks






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






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






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






49. Bbenign activity reported as malicious






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