      Daubert

    • B.

      Frye

    • C.

      IOCE

    • D.

      SWGDE & SWGIT

    Correct Answer
    A. Daubert
    Explanation
    The Daubert Standard, a legal act established in 1993 by the Supreme Court of the United States, explains about the rule of evidence regarding the admissibility of the expert witnesses’ testimony during the federal legal proceedings. Under this act, the plaintiff or defendant can raise a motion to exclude the unqualified evidence at a jury trial.
    In Daubert Standard Act, the Supreme Court passed a rule for federal trial judges to act as “gatekeepers” of scientific evidence. The trial judges should analyze the proffered expert witnesses to decide whether their testimony is both “relevant” and “reliable”. The relevance of a testimony decides whether the expert’s evidence applies to the facts of the case or not. The counsel can opt for Daubert motion before or during the trial to stop the presentation of ineffectual evidence to the jury. The expert’s testimony should be based on the evidence and facts of the case. An expert witness uses the scientific method of investigation to describe that the evidence is reliable and relevant to the case.

It systematically tries all possible combinations until it finds the correct one. This method is time-consuming and resource-intensive, but it is effective against weak passwords that lack complexity or length. Unlike other techniques like dictionary attacks or rule-based attacks, which rely on pre-existing databases or patterns, a brute force attack does not make any assumptions and tries all possibilities.
