Features Of CertGear's CISSP Certification Practice Exam

  • Learn As You Go - Detailed explanations tell you not just the right answer, but why the right answer is right and the wrong answers are wrong. References for further study are also provided.

  • Customized Options - You decide the way you want to take the testing including:
    Timed, Live scoring, Randomization, Ask Incorrect, Show Answer, Select # of questions.

  • Ask Only The Questions You Got Wrong - This is a great feature. At the end of the exam, instead of being asked every question again, you can tell the test engine to only ask you questions that you got incorrect.

  • Randomization - The tests in our certification mode are dynamic, not fixed like some other practice tests are, so you'll get a new test every time. Each test is timed and the objectives are weighted the same as on the real exam.

  • History - The test engine keeps a history of all the exams and scores you have achieved on those tests. You can easily track your progress and help determine when you are ready to take the actual exam.

  • Categories - Many tests contain categories for you to selectively study topics. Additionally, you can see your grade in each category at the end of the exam.

  • Graphic Scoring - Graphical Breakdown Of Exam Results To Pinpoint Areas To Focus Your Study Effort..

  • Updates - Keep Up-To-Date With The Most Current And Most Accurate Exam Questions / Answers / Explanations With Complimentary Product Updates.

 

Free CISSP Certification Sample Questions:

Which of the following best describes an attack against an one-way hash function by attempting to achieve a collision after 2^(m/2) possible trial inputs?

  • [Ans: A]

  • The Birthday attack is based upon the birthday paradox: If you have 23 people in a room, the probability of duplicate birthdays is above 50%. The Birthday attack relies on the idea of producing duplicates, or collisions, at a rate that exceeds expectations. "Birthday attacks are a class of brute-force techniques used in an attempt to solve a class of cryptographic hash function problems. These methods take advantage of functions which, when supplied with a random input, return one of equally likely values. By repeatedly evaluating the function for different inputs, the same output is expected to be obtained after about 2^ (m/2) evaluations."

  • On the other hand, a Man In The Middle attack (MITM) is an attack in which an attacker is able to read, insert and modify messages between two parties without either party knowing that the communication channel between them has been compromised. In a MITM attack, an attacker sniffs packets from a network, modifies them and then inserts them back into the network. Once the attacker intercepts network transmissions between two hosts, the attacker then masquerades as one of the hosts.

  • On the other hand, the Meet-In-The-Middle attack is an attack in which an attacker encrypts the plaintext from one end and decrypts the cipher text from the other end, thus meeting in the middle. This type of attack is applied to double encryption schemes. Specifically, if you encrypt data twice, with two different keys, you usually find yourself susceptible to a meet-in-the-middle attack. That is why Triple-DES is used instead of double encryption, despite the three factor performance penalty.

  • Lastly, Differential cryptanalysis is a chosen plaintext attack where the attacker is able to select inputs and examine outputs in an attempt to derive the encryption key. Differential cryptanalysis exploits the high probability of certain occurrences of plaintext differences and differences into the last round of the cipher.
