Study Notes
Computer Forensics
- Computer forensics involves obtaining and analyzing digital information as evidence.
Related Disciplines
- Computer forensics investigates data retrieved from computer hard drives and other storage media.
- Network forensics examines network traffic to understand how a perpetrator gained access.
- Data recovery focuses on retrieving information lost due to accidental deletion or technical issues.
- Computer forensics specifically aims to recover hidden or deleted data for evidence purposes.
- Disaster recovery also utilizes computer forensics techniques to retrieve lost information.
Public and Private Investigations
- Public investigations involve law enforcement agencies handling criminal cases.
- Private or corporate investigations typically address company policy violations or litigation disputes.
Law Enforcement Agency Investigations
- Criminal cases involve trying suspects for offenses such as burglary, murder, or molestation.
- Computers and networks can be tools used to commit crimes, leading to specific criminal codes addressing computer-related offenses.
- The legal process in criminal cases follows three stages: the complaint, the investigation, and the prosecution.
- A complaint is filed when someone discovers evidence of illegal activity, leading to an investigation and potential prosecution.
Corporate Investigations
- Corporate computer crimes include email harassment, data falsification, discrimination, embezzlement, sabotage, and industrial espionage.
- Publishing clear company policies helps avoid litigation and provides a framework for internal investigations.
- Warning banners displayed upon system startup or network connection inform users about company monitoring rights.
- Designated authorized requesters have the power to conduct investigations based on established company policies.
- Corporate investigations often distinguish between personal and company property, including personal devices connected to company resources.
Professional Conduct
- Professional conduct influences credibility and includes ethical behavior, morals, and standards.
- Maintaining objectivity means forming unbiased opinions during investigations.
- Confidentiality is crucial in both corporate and criminal investigations.
Computer Forensics Defined
- Computer forensics examines digital information as evidence:
- Civil
- Criminal
- Administrative cases
Computer Forensics vs. Other Disciplines
- Computer Forensics: Investigates data from a computer hard drive or storage media
- Network Forensics: Investigates how a perpetrator gained access to a network
- Data Recovery: Recovering lost or deleted information. Typically, you already know what you are looking for
Public & Private Investigations
- Two main categories of computer investigations:
- Public (law enforcement)
- Private (corporate)
Preparing for Computer Investigations
- Public investigations are handled by government agencies
- Follow legal guidelines, including the law of search and seizure, which protects rights of all involved
- Private investigations involve companies and lawyers
- Address company policy violations and legal disputes
Law Enforcement Agency Investigations
- Involves criminal prosecution
- Examples include crimes like burglary, murder, or molestation
- Computers can be tools used in these crimes
- Investigations follow a legal process depending on:
- Location
- Laws
- Rules of evidence
- Stages of a criminal case:
- Complaint
- Investigation
- Prosecution
Understanding Law Enforcement Agency Investigations (continued)
- A criminal case starts when someone finds evidence of an illegal act
- Complainant makes the allegation
- Police officer interviews the complainant and writes a report
- Police blotter documents clues to crimes that have been committed previously
- Investigators gather and process the information related to the complaint
Understanding Corporate Investigations
- Involve private companies and lawyers
- Address company policy violations and legal disputes
- Common corporate computer crimes:
- E-mail harassment
- Data falsification
- Discrimination
- Embezzlement
- Sabotage
- Espionage
Understanding Corporate Investigations (continued)
- Establishing company policies can minimize litigation:
- Clearly defined policies provide a line of authority to conduct internal investigations
- Warning banners inform users of the organization's right to inspect computer systems and network traffic
- Remove expectation of privacy
- Designating an authorized requester:
- Individuals with authority to conduct investigations
- Examples:
- Corporate Security Investigations
- Corporate Ethics Office
- Corporate Equal Employment Opportunity Office
- Internal Auditing
- Legal Department
- Conducting security investigations:
- Examples of situations:
- Abuse of corporate assets (email, internet)
- Company policies help distinguish between abuse problems and potential criminal problems
- Examples of situations:
- Silver-platter doctrine:
- Civilian or corporate agents might deliver evidence to law enforcement officers
Understanding Corporate Investigations (continued)
- Distinguishing personal and company property:
- Company policies should clearly define the difference
- Difficult to distinguish with PDAs, cell phones, and personal notebook computers
- Best practice: Do not allow personally owned devices to connect to company resources
Maintaining Professional Conduct
- Professional conduct determines credibility
- Ethics, morals, and standards of behavior are all important
- Maintaining objectivity means forming unbiased opinions of your cases
- Keep investigations confidential:
- Critical in corporate investigations because cases may become more serious, like murder
