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






3. 53 bytes - 48 bytes for data - 5 bytes for the header






4. A list of files is defined that should be monitored for a change - HIDS software calculates a one-way hash for each file - if a change is made to the file - the hash is changed






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






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






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






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






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






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






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






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






13. 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






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






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






16. 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






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






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






19. 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






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






21. Uniform protection - protected enclaves - information centric - threat vector analysis






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






23. Considered to be a perimeter device






24. OSI






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






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






28. It makes sure the data sent from one side to the other is in a format useful to the other side






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






30. 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 its corresponding IP address






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






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






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






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






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






36. True positive - false positive - true negative - false negative






37. 1 and 2 - Voice/Low speed data - 3 - Voice/Data 10Mb - 4 - Voice/Data 16Mb - 5 - 5e - Voice/Data 100Mb to 1Gb - 6 - Standard for gigabit






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






39. Trying to ID modems in a telephone exchange that may be susceptible to compromise






40. -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






41. Full open - half open (stealth scan) - UDP - Ping






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






43. 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.






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






45. 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.






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






47. Syn - Syn/Ack - Ack






48. One is for talking - one is for implementing






49. Slow - requires stateful data tracking - inspects all fields - including variable-length fields






50. Confidentiality - symmetric encryption
