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






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






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






4. 53 bytes - 48 bytes for data - 5 bytes for the header






5. logic bomb - trojan horse - trap door






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






7. 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






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






9. 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






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






11. Uses flow control to handle network congestion - can send larger amounts of data per packet - has guaranteed delivery of transmitted data - better protection against spoofing - reduces need for error checking at higher OSI layers






12. Connects many WANs - MANs - and LANs - provided via ISP






13. 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






14. Combines the functionality of a hub and bride into a single device - keeps track of MACs attached to each port






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






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






17. Anonymous FTP - FTP passes through clear text - Bounce attacks with the PORT command - user can cause an FTP to open a connection from the FTP's own commands and bypass a firewall






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






19. 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.






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






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






23. Publish separate mail - web - and DNS servers to the internet - provide appropriate access from internal network to internet - protect internal from external attack - provide defense in depth - protect all aspects of the system






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






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






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






27. A time of check/time of use attack that exploits the difference in between when a security control was applied and the time the service was used.






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






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






30. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






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






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






33. Wide Area Network - Larger than MAN or LAN - uses public network - phone lines - and leased lines to tie LAN and MAN over a dispersed area






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






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






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






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






38. Network traffic to the host - typically listens on all interface - uses signature analysis to identify events of interest






39. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






40. Hash Authentication - asymmetric - non repudiation - digital signature - hash + asymmetry






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






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






43. 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






44. Known - unknown - zero day






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






46. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






47. Outside attack from network - Outsider attack from telephone - Insider attack from local network - insider attack from local system - attack from malicious code






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






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






50. 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
