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






2. It handles the establishment and maintenance of connections between systems






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






4. 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






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






6. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






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






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






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






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






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






12. Hash Authentication - asymmetric - non repudiation - digital signature - hash + asymmetry






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






14. 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






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






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






17. Confidentiality - integrity - availability






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






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






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






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






22. A system resource that has no legitimate purpose or reason for someone to connect to it - its purpose is to draw in attackers to understand how they break into a system






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






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






25. 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






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






27. 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






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






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






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






31. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






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






33. 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






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






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






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






37. Isolates systems when they initially connect to the network - allows systems to be scanned and checked prior to being put on a trusted segment






38. Means multiple iterations won't matter. If you encrypt with a key - then re-encrypt - it's the same as using one key.






39. Going around with equipment to detect wireless networks






40. Confidentiality - integrity - availability






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






42. 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






43. Message in its encrypted form






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






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






46. -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






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






48. 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






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






50. Migrate to WPA2 - use strong authentication like PEAP or TTLS - audit network installations - require mutual auth between client and infrastructure equipment
