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






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






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






4. An appliance that controls access between public internet and a companies private network - or between a PC NIC and the rest of the PC.






5. 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






6. Parasitic malware - boot record infector - macro - COM/Script program infector - EXE program infector






7. A low end firewall that can quickly be deployed using existing hardware. They examine packets themselves with no content.






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






9. 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






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






11. FIN 130 - ACK 131 - FIN 570 - ACK 571






12. 53 - DNS - 67 - BootP - 68 - BootP - 69 - TFTP - 123- NTP - 137-139 NBT - 161 - SNMP - 162 - SNMP - 2049 - NFS






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






14. 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






15. 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






16. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






17. Confidentiality - integrity - availability






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






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






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






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






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






23. 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






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






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






26. One is for talking - one is for implementing






27. 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






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






29. True positive - false positive - true negative - false negative






30. Message in its encrypted form






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






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

33. 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






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






35. Protected at rest - protected in transit - secure the key






36. Network scanner.






37. 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






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






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






40. -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






41. 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






42. Confidentiality - symmetric encryption






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






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






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






46. 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






47. 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






48. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






49. 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
