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






2. Full open - half open (stealth scan) - UDP - Ping






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






4. A hash is produced when applied to a monitored file. The hash always generates the same value unless a change was made. HIDS software checks the hashes of monitored files and if a change is found - analyst is notified. - ie: tripwire






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






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






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






8. Syn - Syn/Ack - Ack






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






10. 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






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






12. Considered to be a perimeter device






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






14. Stateful firewalls maintain state of traffic flows






15. 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






16. Connects the physical part of the network (cables) with the abstract (packets and datastreams)






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






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






19. 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






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






21. 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






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






23. destruction of data - leaking confidential information - providing backdoor access






24. 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






25. 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






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






27. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






28. Common backdoor to open a port - port scan scans for open ports on remote host - scans 0 - 65 -535 twice. TCP and UDP






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






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






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






32. Known - unknown - zero day






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. Confidentiality - symmetric encryption






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






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






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






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






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






40. Strips OS commands and characters from input - avoid making system calls from within the app * especially based on user input






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






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






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






44. 53 - DNS - 67 - BootP - 68 - BootP - 69 - TFTP - 123- NTP - 137-139 NBT - 161 - SNMP - 162 - SNMP - 2049 - NFS






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






46. Going around with equipment to detect wireless networks






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






48. Confidentiality - integrity - availability






49. 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






50. 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
