This Week's Reading Takes You From The General Discussion ✓ Solved
This Weeks Reading Takes You From The General Discussion We Held Last
This week's reading takes you from the general discussion we held last week into some more specific details about the role of both criminal justice and non-criminal justice professionals in the IT and computer forensics world, as well as why it is important that you understand the basic principles and concepts of the criminal justice process. Then we get into the meat of what you would do and how you would interface with law enforcement in the event you have to conduct a forensic system analysis. The readings in module 2 again stress the importance of understanding the criminal justice process, as well as discuss different types of devices or file systems that may contain information critical to your analysis.
Among the basic concepts to understand this week are that there are many types of evidence one could find in digital data. Understanding what data you may find, even if it is not evidence of a crime, is important to preparing a digital examination/analysis plan. Let’s look at a non-technical example… When a law enforcement officer applies for a warrant to search a residence, the officer must specify for what it is he or she is searching; if the case involves a stolen car, then the officer’s search will be limited to only those locations a stolen car, or pieces of a stolen car (in case it was chopped), could be located. It would be unwise to just list the stolen car on the warrant, as (in the interpretation of the court) might only limit the officer to the whole car, intact.
So, the officer has to determine in the beginning of their search what could have happened to the car (attempting to account for all the possibilities) so his or her search is complete (and most likely to yield results). The officer will also have to justify (in the affidavit) why he or she believes that the car could be found in smaller pieces. To that end, an officer with auto theft experience may also be able to state that, in his or her experience, stolen cars are often broken down into smaller components, which can be identified with certainty as belonging to the original stolen car, as well as where such components could be hidden. It would most likely not be enough for the officer to simply assert that cars are broken down and sold for parts, if he or she wants to justify seizing an ashtray; the ashtray would need some specific characteristics to do that like a serial number, or other unique identifying artifact.
Search warrants and searches are, therefore, most often limited in scope to items for which the searcher is looking (i.e., nearly always evidence of a crime or wrongdoing). You cannot look for an elephant in a kitchen drawer! I know that sounds absurd, but it is an excellent metaphor… However, if you were looking for narcotics, they could be hidden almost anywhere, and you could justify a much broader search. In this example, digital evidence is much more akin to narcotics than you may think, with evidential data often occurring in hidden, strange, or unlikely places. As such, warrants to search for digital evidence often cast a “wide net,” but cannot be so overly broad as to not be supported by probable cause or violate someone’s Fourth Amendment protections and implied rights to privacy under the Constitution.
Do not despair, however, if you are not a law enforcement officer… The requirement to obtain a search warrant does not apply to searches by private individuals or non-government organizations, as long as the individual(s) have the authority to conduct the search (e.g., IT security personnel are searching a computer owned by their company for company data, or an employee gives the company consent to search for their personal data). Judicially, the Court evaluates whether your activity was an extension of the government (law-enforcement); acting on their behalf or assisting them. However, even those searches may be limited to certain parts of the computer system(s) or network(s). If a person is allowed to use a personally-owned flash drive at work, and that drive is connected to the computer, you still may not be able to search it without the employee's consent.
All of these examples depend heavily on established company policies and what warnings were given to the employee. The readings this week identify several types of devices on which digital evidence could be found. For this week’s discussion, please select two of the devices described in your readings (or other devices, if you prefer). For each device, answer the following questions below in detail. Please discuss thoroughly and substantively in your post. Additionally, respond in a thorough, substantive, intelligent way to at least one of your fellow classmates that adds to our discussion and learning of this week’s topic! For each, state what types of evidence you would look for on those devices in detail Explain what limitations or hurdles you would have to clear before searching each of the devices (BOTH as a company IT professional and a law enforcement officer). Identify what, if any, policies would need to be in place for you to search as a private employee, as well as what limits can be placed on the search by police.
Sample Paper For Above instruction
The role of digital evidence in criminal justice and private sector investigations has become increasingly significant as technology advances and digital devices become ubiquitous. Understanding how to analyze various devices for evidence, along with the legal and procedural considerations, is crucial for both IT professionals and law enforcement officers. This paper explores the types of evidence found on two common types of devices—personal computers and mobile smartphones—and discusses the limitations and policies governing searches of these devices in both private and law enforcement contexts.
Evidence on Personal Computers and Mobile Smartphones
Personal computers and mobile smartphones are among the most data-rich devices, often harboring evidence of criminal activities or policy violations. On personal computers, evidence might include documents, emails, internet browsing history, downloaded files, photos, videos, and system logs. For law enforcement, digital forensics involves recovering deleted files, analyzing metadata, and identifying unusual activity such as unauthorized access or data exfiltration (Rogers, 2020).
Similarly, mobile smartphones contain call logs, text messages, emails, app data, GPS location history, and multimedia files. These can be critical in investigations involving fraud, stalking, drug trafficking, or cybercrime (Casey, 2017). The potential evidence includes geolocation data, communication records, and activity logs. Smartphone forensics requires extracting data without tampering and often supports encryption removal or bypassing security features (Garcia & Martinez, 2019).
Limitations and Hurdles in Searching Devices
When conducting searches of personal computers or smartphones, several limitations and hurdles must be addressed. As a company IT professional, the primary considerations include adherence to company policies, privacy rights, and the need for authorized access. Policies regarding the scope of allowed searches, employee consent, and data retention should be established beforehand (Johnson, 2018). For example, if an employee consents to a search, it must be documented, and the scope should be limited to work-related data unless explicitly permitted otherwise.
Law enforcement officers face additional challenges, including obtaining a valid search warrant supported by probable cause, as required under the Fourth Amendment. Encrypted devices, secure operating systems, and anti-forensic techniques complicate evidence acquisition (Bunting & Bunting, 2020). Encrypted data may require specialized tools to decrypt, and officers must demonstrate that the search adheres to legal standards to avoid exclusion of evidence in court.
Policies and Limits on Searches
In a corporate setting, policies must clearly define when and how searches are conducted, emphasizing employee privacy rights and the company's right to protect its assets. Policies could specify that searches are performed with prior notice, within specific parameters, and with documentation. In contrast, law enforcement searches are constrained by judicial oversight and constitutional protections. A search warrant limits the scope geographically, temporally, and in terms of the data targeted, preventing overreach (Kerr, 2018).
Conclusion
Both private sector and law enforcement personnel must navigate complex legal and technical landscapes when searching digital devices. Knowledge of evidence types, technical hurdles, and policy frameworks ensures that searches are effective, lawful, and respectful of individual rights. As technology continues to evolve, ongoing training and clear policies are essential to maintain integrity and due process in digital investigations.
