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






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






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






4. Confidentiality - integrity - availability






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






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






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






8. Physical layer - Data link layer - Network Layer - Transport Layer - Session Layer - Presentation Layer - Application Layer






9. 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






10. Considered to be a perimeter device






11. Worms and Wireless - modems - tunnel anything through HTTP - social engineering






12. deployment challenges including topology and access limitations - analyzing encrypted traffic - quantity vs. quality of signatures - performance limitations with extensive analysis techniques - very costly for proper management






13. Used for connecting two physical segments of a network - segments traffic - breaks up collision domains - not generally used because of switches






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






15. One is for talking - one is for implementing






16. 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.






17. 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






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






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






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






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






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






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






24. -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






25. 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






26. free windows based wireless scanner for 802.1b - detects access point settings - supports GSP integration - identifies networks as encrypted or unencrypted






27. 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






28. Connects the physical part of the network (cables) with the abstract (packets and datastreams)






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






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






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






32. 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






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






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






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






36. OSI






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






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






40. fast - with little fidelity - examines header information and limited payload data






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

42. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






43. 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






44. 53 bytes - 48 bytes for data - 5 bytes for the header






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






46. Simplest form of a research honeypot - useful in identifying nature of TCP scans - allows attacker to complete 3-way handshake - listens on a defined port - logs incoming requests for analysis






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






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






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






50. An agreement on how different computer will work - protocols define the format and order of messages and what to do upon receipt of the messages - basically the rules of the network
