Test your basic knowledge |

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. Most common approach - firewall - VPN - intrusion detection - AV - disk encryption - all parts of the organization receive equal protection - particularly vulnerable to malicious inside attacks






2. Allows admins to remotely access a system for troubleshooting. - E.g VNC - GoToMyPc - PC Anywhere






3. Uniform protection - protected enclaves - information centric - threat vector analysis






4. Unencrypted message in its original form






5. open source tool for monitoring - can be used as a NIDS - has quick updates and flexibility for custom rules






6. Switches networks make it difficult to monitor traffic in promiscuous mode - topology must be able to support traffic aggregation for monitoring






7. Infects the EXE and make them operate slightly different - when infected - exe header sizes are altered to point to the appended viral code






8. Not frequently seen on LANs because of expense - because of its traffic predictability and high bandwidth support - it's good for video streaming - encapsulates common protocols - uses virtual path identifiers to create end to end connectivity - has






9. Known - unknown - zero day






10. Network scanner.






11. deployment challenges including topology and access limitations - analyzing encrypted traffic - quantity vs. quality of signatures - performance limitations with extensive analysis techniques - very costly for proper management






12. 1. physical 2. data 3. network 4. transport 5. session 6. presentation 7. application






13. A low end firewall that can quickly be deployed using existing hardware. They examine packets themselves with no content.






14. Take the file and try to compress it. If it compresses - it means there is a pattern and it's more easily crackable

15. Provides insight into traffic on the network - help detect problems with network operations - provides auditing for other security measures






16. Good for multimedia - can use small single packets - multicasting is required - speed is the highest priority






17. Maintains complete TCP connection state and sequencing through 2 connections - address translation built-in by virtue of second connection above






18. Not a replacement for firewalls - hardening - strong policies - or other DiD methods - low maintenance - inexpensive






19. Netmasks or subnets provide a method for identifying what portion of an address is the network - and what portion is the host






20. Threat requires a vector to cross the vulnerability - stop the ability of the threat to use the vector






21. Weakness in a system - inherent in a complex system - majority are due to poor coding - gateway by which threats are manifested






22. The Practice of sending an ACK inside another packet going to the same destination






23. Small program triggered by an event that provides an action. E.g. scheduled file removal if countdown isn't reset - ie: employee was fired






24. Protects internal/external systems from attack - filters communications based on content - performs NAT - encrypts communications for VPN - logging to aid in intrusion detection






25. keeps the same letters - but changes the position within the text - easy to break - can be combined with substitution






26. Full open - half open (stealth scan) - UDP - Ping






27. Trivial File Transfer Protocol - method to transfer files from one device to another without needing authentication






28. Resource exhaustion like DDoS or fork attack - unexpected input value the machine does not know how to process






29. It interacts with data and prepares it to be transmitted across the network. It ensures reliable connectivity from end-to-end






30. Means multiple iterations won't matter. If you encrypt with a key - then re-encrypt - it's the same as using one key.






31. Stateful firewalls maintain state of traffic flows






32. Very simplistic. All systems are attached to the same cable segment. Rarely used because they're unreliable - low fault tolerance - poor traffic isolation - with limited scalability






33. 53 - DNS - 67 - BootP - 68 - BootP - 69 - TFTP - 123- NTP - 137-139 NBT - 161 - SNMP - 162 - SNMP - 2049 - NFS






34. Syn - Syn/Ack - Ack






35. Message in its encrypted form






36. Relies on executable code insertion and user interaction to spread






37. A sends a SYN packet to B - B acknowledges with a SYN/ACK - A replies with ACK






38. A hash is produced when applied to a monitored file. The hash always generates the same value unless a change was made. HIDS software checks the hashes of monitored files and if a change is found - analyst is notified. - ie: tripwire






39. Program disguised as something helpful - only to perform actions the user did not intend. Opening ports - installing other programs - etc.






40. Going around with equipment to detect wireless networks






41. Intellectual property - business goals - validated data - historical






42. An agreement on how different computer will work - protocols define the format and order of messages and what to do upon receipt of the messages - basically the rules of the network






43. Provides insight into the tactics - motives - and attacker tools






44. UDP based infection - infected through vulnerability in SQL server - caused DoS on saturated networks






45. Physical layer - Data link layer - Network Layer - Transport Layer - Session Layer - Presentation Layer - Application Layer






46. low interaction production honeypot - network daemon that can simulate other hosts - each host can appear as a different OS






47. fast - with little fidelity - examines header information and limited payload data






48. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






49. Replicates traffic onto all ports - no traffic monitoring - cannot control which ports should or shouldn't receive frames - forming a large collision domain.






50. Uses inclusive or exclusive lists - inclusive analysis utilizes a list of keywords - exclusive analysis utilizes a list of events that can be ignored
