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. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






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






3. Relies on executable code insertion and user interaction to spread






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






5. 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






6. Most common approach - firewall - VPN - intrusion detection - AV - disk encryption - all parts of the organization receive equal protection - particularly vulnerable to malicious inside attacks






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






8. Considered to be a perimeter device






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






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






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






12. Message in its encrypted form






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






14. 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






15. 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






16. Going around with equipment to detect wireless networks






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






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






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






20. 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






21. Bits of code embedded in programs to quickly gain access at a later time






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






23. It interacts with data and prepares it to be transmitted across the network. It ensures reliable connectivity from end-to-end






24. A system resource that has no legitimate purpose or reason for someone to connect to it - its purpose is to draw in attackers to understand how they break into a system






25. The Practice of sending an ACK inside another packet going to the same destination






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






27. 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 its corresponding IP address






28. logic bomb - trojan horse - trap door






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






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

31. Trivial File Transfer Protocol - method to transfer files from one device to another without needing authentication






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






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






34. 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






35. A list of files is defined that should be monitored for a change - HIDS software calculates a one-way hash for each file - if a change is made to the file - the hash is changed






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






37. Very simplistic. All systems are attached to the same cable segment. Rarely used because they're unreliable - low fault tolerance - poor traffic isolation - with limited scalability






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






39. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






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






41. Syn - Syn/Ack - Ack






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






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






44. -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






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






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






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






48. Simple attack done by simply browsing available information that's allowed on a local network.






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






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