You learn from your internal information security department that an employee has been using password-cracking software to access confidential customer insurance information. The account information extracted is unknown at this time, though it appears as though multiple computers were being used for the crime and it isn’t clear whether an attack is currently in progress. The employee has been detained but his computers remain online.

  3. Explicate the importance of creating an order of volatility by identifying the potential evidence that is the most volatile. Explain, in detail, how you would extract this evidence.
  4. Identify the high-level steps that would be performed in collecting and analyzing the evidence. Include steps that are required, as well as what should not be done, in order to maintain the potential admissibility of evidence.
