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. One is for talking - one is for implementing






2. An attacker spoofs the victim's IP and sends an ICMP ECHO request to the broadcast address of a network. When every system responds - a DoS occurs.






3. 1 and 2 - Voice/Low speed data - 3 - Voice/Data 10Mb - 4 - Voice/Data 16Mb - 5 - 5e - Voice/Data 100Mb to 1Gb - 6 - Standard for gigabit






4. packet filter firewalls rely on TCP flags to determine connection state. Attacker can send ACK packets only to bypass firewall.






5. 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






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






7. Syn - Syn/Ack - Ack






8. 53 bytes - 48 bytes for data - 5 bytes for the header






9. Attempt to manipulate or trick a person into providing information or access - bypass network security by exploiting humans - vector is often outside attack by telephone or visitor inside






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






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. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






13. 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.






14. Infects MBR - no network spreading potential






15. Handles the network address scheme and connectivity of multiple network segments. It handles communication.






16. A list of files is defined that should be monitored for a change - HIDS software calculates a one-way hash for each file - if a change is made to the file - the hash is changed






17. Spread as an office attachment with executable code programmed using macro facility - targets are data files - visual basic editor and other macro languages - payload executes when the code is launched






18. Improper deployment can increase attack risk - if production systems aren't sufficiently protected - they can be vulnerable from a honeypot - legal liability






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






20. Connection oriented - before systems can communicate over an ATM network - they must establish a virtual circuit between each other - this can span across multiple ATM switches that also handle communications for other systems - at the end of the con






21. Prepends to the beginning of the file and gains control when the first instruction of the infected COM file is executed - appending to the end - virus writes its payload to the end and inserts jump instruction as the first instruction - which execute






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

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






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. Simplest form of a research honeypot - useful in identifying nature of TCP scans - allows attacker to complete 3-way handshake - listens on a defined port - logs incoming requests for analysis






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






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






28. Isolates systems when they initially connect to the network - allows systems to be scanned and checked prior to being put on a trusted segment






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






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






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






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






33. 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






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






35. Network scanner.






36. Slow - requires stateful data tracking - inspects all fields - including variable-length fields






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






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






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






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






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






42. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






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






44. Four layers - Network Layer - Internet Layer - Transport Layer - Application layer






45. Confidentiality - integrity - availability






46. TCP/IP - the IP protoco - The core routing protocol of the internet - - deals with transmission of packets between end points - defines the addressing scheme for the internet






47. Stateful firewalls maintain state of traffic flows






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






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






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