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. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






2. 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






3. Allows segmentation of a switch into different networks - regardless of where a system is plugged in - creates separate networks through software not hardware

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






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






6. Infects MBR - no network spreading potential






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






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






9. Stateful firewalls maintain state of traffic flows






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






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






12. Unencrypted message in its original form






13. Network scanner.






14. 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






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






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






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






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






20. 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






21. Going around with equipment to detect wireless networks






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






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






24. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






25. Weakness in a system - inherent in a complex system - majority are due to poor coding - gateway by which threats are manifested






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






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






28. 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.






29. Confidentiality - integrity - availability






30. 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






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






32. Known - unknown - zero day






33. size is whatever the length of the UDP portion of the packet. Could be as large as 65 -535






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






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






36. 53 bytes - 48 bytes for data - 5 bytes for the header






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






38. Spread as an office attachment with executable code programmed using macro facility - targets are data files - visual basic editor and other macro languages - payload executes when the code is launched






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






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






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






42. 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






43. 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






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






45. Replicates traffic onto all ports - no traffic monitoring - cannot control which ports should or shouldn't receive frames - forming a large collision domain.






46. 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






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






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






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