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. 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






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






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






4. 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






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

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






7. It allows the transport layer to detect when the UDP headers or the payload have been modified in transit






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






9. 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






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

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


11. 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






12. 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.






13. 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






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






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






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






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






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






20. 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






21. 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






22. True positive - false positive - true negative - false negative






23. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






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






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






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






27. The practice of sending an ACK inside another packet going to the same destination






28. An attacker recruits zombie systems ahead of time to simultaneously release a flood of traffic at a specific target.






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






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






31. Infects MBR - no network spreading potential






32. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






33. 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






34. 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






35. 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






36. OSI






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






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






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






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






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






42. Going around with equipment to detect wireless networks






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






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






45. 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






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






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






48. Most commonly used transport protocol today - ensures reliable packet delivery - has error handling built in






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






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