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






2. 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






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






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






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






6. Intellectual property - business goals - validated data - historical






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






8. Application layer attacks may get through - dialup - VPN - extranet connections may bypass firewalls






9. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






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






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






12. 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






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






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






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






17. 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






18. 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






19. Program disguised as something helpful - only to perform actions the user did not intend. Opening ports - installing other programs - etc.






20. 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.






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






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






23. 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






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






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






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






27. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






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






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






30. 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






31. Not a replacement for firewalls - hardening - strong policies - or other DiD methods - low maintenance - inexpensive






32. Unencrypted message in its original form






33. Confidentiality - integrity - availability






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






35. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






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






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






38. Good for multimedia - can use small single packets - multicasting is required - speed is the highest priority






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






40. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






41. Going around with equipment to detect wireless networks






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






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






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






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






46. 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






47. A cracking tool inserted into the OS that allows the attacker to do as they please.






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






49. Resource exhaustion like DDoS or fork attack - unexpected input value the machine does not know how to process






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