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

2. Going around with equipment to detect wireless networks






3. The practice of sending an ACK inside another packet going to the same destination






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






5. flags anomalous conditions in traffic on the network - requires understanding on what is normal - bases good traffic as a baseline






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






7. Intrusion detection system - it reports attacks against monitored systems/networks






8. CIDR is a shorthand way of specifying which portion of the address is the network - and which portion is the host






9. 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






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






11. Network scanner.






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






13. 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






14. Message in its encrypted form






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






16. Metropolitan area network - spans across city or town - larger than a LAN - uses fiber for backbone






17. logic bomb - trojan horse - trap door






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






19. Unified data carrying service - replacing from replay and ATM






20. A spoofed IP is used to send a SYN to the target. It then responds with a SYN/ACK that never receives the final ACK to complete the handshake. This occupies a portion of the target's pre-established buffer for TCP and can prevent the target from acce






21. Work groups that require additional protection are segmented from the rest of the internal organization - restricting access to critical segments - system of VPNs - internal firewall - VLANs and ACLs






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






23. Infects MBR - no network spreading potential






24. Identify critical assets and provide layered protection - data is accessed by applications - applications reside on hosts - hosts operate on networks






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






26. Used for connecting two physical segments of a network - segments traffic - breaks up collision domains - not generally used because of switches






27. size is whatever the length of the UDP portion of the packet. Could be as large as 65 -535






28. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






29. free windows based wireless scanner for 802.1b - detects access point settings - supports GSP integration - identifies networks as encrypted or unencrypted






30. 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.






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






32. An attacker recruits zombie systems ahead of time to simultaneously release a flood of traffic at a specific target.






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






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






35. 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






36. Infected millions through various methods - vulnerability in the MS Server Service - brute force admin password through network shares - infect removable devices with a malicious autorun script






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






38. 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






39. 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 its corresponding IP address






40. Application layer attacks may get through - dialup - VPN - extranet connections may bypass firewalls






41. It interacts with the application layer to determine which network services will be required






42. Trying to ID modems in a telephone exchange that may be susceptible to compromise






43. 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






44. Stateful firewalls maintain state of traffic flows






45. NTP - BootP/DHCP - NFS file systems - SNMP - TFTP






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






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






48. Simple attack done by simply browsing available information that's allowed on a local network.






49. An attempt to gain access by bombarding it with guesses until the password is found.






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