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. 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






2. 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






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






4. -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






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






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






7. 53 - DNS - 67 - BootP - 68 - BootP - 69 - TFTP - 123- NTP - 137-139 NBT - 161 - SNMP - 162 - SNMP - 2049 - NFS






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






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






10. 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






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






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






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






14. 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.






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






16. 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






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






18. 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






19. 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






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






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






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






23. 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






24. 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






25. 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






26. Syn - Syn/Ack - Ack






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






28. Confidentiality - integrity - availability






29. 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.






30. Free linux WLAN analysis tool - completely passive - cannot be detected - supports advanced GPS integration and mapping features - used for wardriving - WLAN vulerability assessment






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






32. 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






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






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






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






36. OSI






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






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






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






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






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






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






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






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






45. 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






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






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

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






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






50. 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.
