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. Relies on executable code insertion and user interaction to spread






2. risk = threat x vulnerability - impossible to eliminate - security is an exercise in loss reduction






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






4. Used by IDS for a baseline before analysis - attackers will try to de-normalize traffic to evade detection - IDS will normalize data for understood protocols






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






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

7. 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






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






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






11. Going around with equipment to detect wireless networks






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






13. OSI






14. Unencrypted message in its original form






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






16. 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.






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






18. One is for talking - one is for implementing






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






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. Four layers - Network Layer - Internet Layer - Transport Layer - Application layer






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






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






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






25. 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.






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






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






28. packet filter firewalls rely on TCP flags to determine connection state. Attacker can send ACK packets only to bypass firewall.






29. 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






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






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






32. Uses a 1 to 1 substitution of arbitrary numbers - given a one character mapping - you cannot determine the key






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






34. Considered to be a perimeter device






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






36. Infects MBR - no network spreading potential






37. Stateful firewalls maintain state of traffic flows






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






39. -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






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






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






43. rules indicate criteria in packets that represent events of interest - rules are applied to packets as they are received - alerts are created when matches are found






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






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






46. 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






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






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






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






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