If an employee's computer has been used by a fraudulent employee to commit a crime, the hard disk may be seized as evidence and once the investigation is complete it would follow the normal steps of the Evidence Life Cycle. In such case, the Evidence life cycle would not include which of the following steps listed below?
正解: D
Explanation/Reference:
Unless the evidence is illegal then it should be returned to owner, not destroyed.
The Evidence Life Cycle starts with the discovery and collection of the evidence. It progresses through the following series of states until it is finally returned to the victim or owner:
* Acquisition collection and identification
* Analysis
* Storage, preservation, and transportation
* Presented in court
* Returned to victim (owner)
The Second edition of the ISC2 book says on page 529-530:
Identifying evidence: Correctly identifying the crime scene, evidence, and potential containers of evidence.
Collecting or acquiring evidence: Adhering to the criminalistic principles and ensuring that the contamination and the destruction of the scene are kept to a minimum. Using sound, repeatable, collection techniques that allow for the demonstration of the accuracy and integrity of evidence, or copies of evidence.
Examining or analyzing the evidence: Using sound scientific methods to determine the characteristics of the evidence, conducting comparison for individuation of evidence, and conducting event reconstruction.
Presentation of findings: Interpreting the output from the examination and analysis based on findings of fact and articulating these in a format appropriate for the intended audience (e.g., court brief, executive memo, report).
Note on returning the evidence to the Owner/Victim
The final destination of most types of evidence is back with its original owner. Some types of evidence, such as
drugs or drug paraphernalia (i.e., contraband), are destroyed after the trial.
Any evidence gathered during a search, although maintained by law enforcement, is legally under the control of the courts. And although a seized item may be yours and may even have your name on it, it might not be returned to you unless the suspect signs a release or after a hearing by the court.
Unfortunately, many victims do not want to go to trial; they just want to get their property back.
Many investigations merely need the information on a disk to prove or disprove a fact in question; thus, there is no need to seize the entire system. Once a schematic of the system is drawn or photographed, the hard disk can be removed and then transported to a forensic lab for copying.
Mirror copies of the suspect disk are obtained using forensic software and then one of those copies can be returned to the victim so that business operations can resume.
