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






2. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






3. Known - unknown - zero day






4. Confidentiality - integrity - availability






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






6. A TCP version of ping - sends custom TCP packets to a host and listens for replies - enables port scanning and spoofing simultaneously






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






8. Take the file and try to compress it. If it compresses - it means there is a pattern and it's more easily crackable

9. Trying to ID modems in a telephone exchange that may be susceptible to compromise






10. -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






11. Unencrypted message in its original form






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






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






14. 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.






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






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






17. 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






18. 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






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






20. Small program triggered by an event that provides an action. E.g. scheduled file removal if countdown isn't reset - ie: employee was fired






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






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






23. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






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






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






26. Slow - requires stateful data tracking - inspects all fields - including variable-length fields






27. 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.






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






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






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






31. Going around with equipment to detect wireless networks






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






33. 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.






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






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






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






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






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






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






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






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






42. 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






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






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






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






46. True positive - false positive - true negative - false negative






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






48. 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






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






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