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. 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






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






3. It handles the establishment and maintenance of connections between systems






4. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






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






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






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






8. Migrate to WPA2 - use strong authentication like PEAP or TTLS - audit network installations - require mutual auth between client and infrastructure equipment






9. 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






10. Confidentiality - integrity - availability






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






12. Most commonly used transport protocol today - ensures reliable packet delivery - has error handling built in






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






14. Multiple levels of protection must be deployed - an exercie in detection - measures must be across a wide range of controls - compromises happen when people leave sites - risk - CIA triad - strategies






15. Protected at rest - protected in transit - secure the key






16. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






17. A system resource that has no legitimate purpose or reason for someone to connect to it - its purpose is to draw in attackers to understand how they break into a system






18. ATM supports two types of virtual circuits: permanent virtual circuits and switches virtual circuit - PVC is set up in advance - usually manually - SVC is established automatically through a signaling protocol and can be created on the fly - establis






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






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






21. Protocol for mapping an IP address to a physical machine address that is recognized on the local network - A table - usually called the ARP cache - is used to maintain a correlation between each MAC and it's corresponding IP address






22. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






23. Poor programming without error checking can allow commands to be run in an input field. This can point to a command further in the buffer that will execute the attacker's payload.






24. Syn - Syn/Ack - Ack






25. Handles transmissions across the physical media like wires - fiber - etc






26. removable media - email attachments - web browsing - social networking - network vulnerabilities - IM applications - p2p






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






28. A cracking tool inserted into the OS that allows the attacker to do as they please.






29. local area network - small network confined to small location - all equipment owned by a single entity - vulnerable to inside threats and logic bombs






30. An appliance that controls access between public internet and a companies private network - or between a PC NIC and the rest of the PC.






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






32. An FTP that allows downloads only if the user knows the exact name of the file they're looking for






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






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

35. When someone has compromised the integrity of data or a program. Allows attackers to create backdoors.






36. Switches along the path can be requested to allocate the desired amount of bandwidth. If the circuit has the required bandwidth - the circuit is set up.






37. -Malicious code might execute destructive overwrite to hard disks -Malicious mas mailing code might expose sensitive information to the internet - web server compromise might expose organization to ridicule - Web server compromise might expose custom






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






39. It allows the transport layer to detect when the UDP headers or the payload have been modified in transit






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






41. Attaches itself to existing program files and activated when the exe is launched






42. Personal area network - phone tethering - bluetooth - etc






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






44. logic bomb - trojan horse - trap door






45. Allows segmentation of a switch into different networks - regardless of where a system is plugged in - creates separate networks through software not hardware

46. Malware - insider threat - natural disaster - terrorism - pandemic






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






48. Used by IDS for a baseline before analysis - attackers will try to de-normalize traffic to evade detection - IDS will normalize data for understood protocols






49. Bits of code embedded in programs to quickly gain access at a later time






50. War dialing - war driving - Sniffing - eavesdropping - dumpster diving - social engineering
