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 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.






2. 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






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






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






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






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






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






8. 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






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






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






11. 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






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






13. Unencrypted message in its original form






14. Maintains complete TCP connection state and sequencing through 2 connections - address translation built-in by virtue of second connection above






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






16. A low end firewall that can quickly be deployed using existing hardware. They examine packets themselves with no content.






17. 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






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






19. 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






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






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






22. Poor programming without error checking can allow commands to be run in an input field. This can point to a command further in the buffer that will execute the attacker's payload.






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






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. 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






26. Message in its encrypted form






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






28. Network scanner.






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






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






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






32. Going around with equipment to detect wireless networks






33. 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






34. An appliance that controls access between public internet and a companies private network - or between a PC NIC and the rest of the PC.






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






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






37. A TCP version of ping - sends custom TCP packets to a host and listens for replies - enables port scanning and spoofing simultaneously






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






39. 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






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






41. logic bomb - trojan horse - trap door






42. 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


43. Uses inclusive or exclusive lists - inclusive analysis utilizes a list of keywords - exclusive analysis utilizes a list of events that can be ignored






44. Handles the network address scheme and connectivity of multiple network segments. It handles communication.






45. 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






46. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






47. 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
