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






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






3. 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.






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






5. Unencrypted message in its original form






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






7. 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






8. 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






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






10. 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






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






12. Known - unknown - zero day






13. Provides insight into traffic on the network - help detect problems with network operations - provides auditing for other security measures






14. Connects many WANs - MANs - and LANs - provided via ISP






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






16. Confidentiality - symmetric encryption






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






18. 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






19. Stateful firewalls maintain state of traffic flows






20. One is for talking - one is for implementing






21. open source tool for monitoring - can be used as a NIDS - has quick updates and flexibility for custom rules






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






23. Protects internal/external systems from attack - filters communications based on content - performs NAT - encrypts communications for VPN - logging to aid in intrusion detection






24. 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






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






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






27. Means multiple iterations won't matter. If you encrypt with a key - then re-encrypt - it's the same as using one key.






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






29. 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






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






31. 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






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






33. Attempt to manipulate or trick a person into providing information or access - bypass network security by exploiting humans - vector is often outside attack by telephone or visitor inside






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






35. Attacks systems through known vulnerabilities - automatically scans for more systems to attack - lowers system defenses - installs rootkit or root shell - opens up back doors - self contained malware that can copy itself






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






37. -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






38. Identify critical assets and provide layered protection - data is accessed by applications - applications reside on hosts - hosts operate on networks






39. Infects MBR - no network spreading potential






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






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






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






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






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






45. Considered to be a perimeter device






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






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






48. Physical layer - Data link layer - Network Layer - Transport Layer - Session Layer - Presentation Layer - Application Layer






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






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