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. Going around with equipment to detect wireless networks






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






3. 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






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






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






7. 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






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






9. 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






10. 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






11. 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






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






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






14. Stateful firewalls maintain state of traffic flows






15. 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






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






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






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






19. 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






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






21. Worms and Wireless - modems - tunnel anything through HTTP - social engineering






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






23. It makes sure the data sent from one side to the other is in a format useful to the other side






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






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






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






27. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






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






29. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






30. Known - unknown - zero day






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






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






33. 53 - DNS - 67 - BootP - 68 - BootP - 69 - TFTP - 123- NTP - 137-139 NBT - 161 - SNMP - 162 - SNMP - 2049 - NFS






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






35. logic bomb - trojan horse - trap door






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






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






38. 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






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






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






41. 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






42. Uses a 1 to 1 substitution of characters - rotate the alphabet by 'n' number of characters - rot+X means rotate the letters X characters






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






44. One is for talking - one is for implementing






45. 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.






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






47. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0
