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






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






3. 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






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






5. 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






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






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






8. Intrusion detection system - it reports attacks against monitored systems/networks






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






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






11. -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






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






13. Unencrypted message in its original form






14. 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.






15. 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.






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






17. Message in its encrypted form






18. 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






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






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






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






23. flags anomalous conditions in traffic on the network - requires understanding on what is normal - bases good traffic as a baseline






24. 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






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






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






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






28. 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






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






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






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






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






33. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






34. Infects MBR - no network spreading potential






35. 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






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






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






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






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






40. 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






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






42. Metropolitan area network - spans across city or town - larger than a LAN - uses fiber for backbone






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






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






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






46. 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






47. Confidentiality - integrity - availability






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






49. Stateful firewalls maintain state of traffic flows






50. 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
