Study Notes

Computer Forensics Definition

Computer forensics involves obtaining and analyzing digital information as evidence in legal cases, including civil, criminal, or administrative proceedings.

Computer Forensics vs. Other Disciplines

Computer forensics investigates digital data retrieved from computer hard drives or other storage media.
Network forensics focuses on how attackers or perpetrators gain access to a network.
Data recovery aims to retrieve accidentally deleted information or data lost during power surges or server crashes.
Computer forensics specifically focuses on recovering hidden or deleted data for use as evidence.
This evidence can be inculpatory (incriminating) or exculpatory (exonerating).
Disaster recovery employs computer forensics techniques to retrieve lost information.
Investigators often work collaboratively to secure computers and networks within an organization.

Public and Private Investigations

Computer investigations and forensics fall into two categories: public and private/corporate investigations.

Preparing for Computer Investigations

Public investigations involve government agencies responsible for criminal investigations and prosecutions.
These organizations must adhere to legal guidelines, specifically the law of search and seizure, which protects the rights of everyone, including suspects.

Law Enforcement Agency Investigations

Criminal cases involve trying a suspect for a criminal offense, such as burglary, murder, or molestation.
While computers and networks might serve as tools to commit crimes, specific computer crime laws address offenses like data theft.
Legal processes vary based on local customs, legislative standards, and rules of evidence.
Criminal cases typically involve three stages: the complaint, the investigation, and the prosecution.
A police officer documents the initial complaint and collects evidence to support the allegation.
Investigators then process and analyze the collected information.

Corporate Investigations

Private or corporate investigations involve private companies and lawyers dealing with company policy violations and litigation disputes.
Corporate computer crimes range from e-mail harassment and data falsification to gender and age discrimination, embezzlement, sabotage, and industrial espionage.
Establishing company policies helps avoid litigation by providing clear guidelines for employees.
Well-defined policies empower computer investigators and forensic examiners to conduct internal investigations.
Displaying warning banners, typically when a computer starts or connects to the corporate network, informs users that the organization reserves the right to inspect systems and network traffic.
This helps establish the organization's right to conduct investigations and removes any expectation of privacy.
Designating an authorized requester, often defined by executive management, grants individuals the authority to initiate investigations.
This authority should be vested in groups like Corporate Security Investigations, the Corporate Ethics Office, Corporate Equal Employment Opportunity Office, Internal Auditing, the general counsel, or the Legal Department.
Security investigations commonly address issues like abuse or misuse of corporate assets, e-mail abuse, and internet abuse.
Corporations often follow the silver-platter doctrine, which describes the process when a civilian or corporate investigator delivers evidence to a law enforcement officer.
It's crucial to distinguish between personal and company property, especially with devices like PDAs, cell phones, and personal notebooks.
To avoid potential issues, companies often restrict the use of personally owned devices on company-owned resources to prevent data mixing.

Maintaining Professional Conduct

Professional conduct is essential for maintaining credibility and includes ethical behavior, morals, and high standards.
Maintaining objectivity involves forming and upholding unbiased opinions regarding cases.
Confidentiality is crucial to preserving an investigation's credibility, especially in corporate settings.
Rare instances may arise where a corporate case progresses to a criminal case, potentially involving serious offenses like murder.
