Project 2 For The Purpose Of This Project You Are Still I

Project 2for The Purpose Of This Project You Are Still The Infosec Sp

For this project, you are tasked with continuing your role as the information security (Infosec) specialist for Makestuff Company. The scenario involves conducting digital and non-digital forensic investigations related to a former employee, Mr. Yourprop. You are to determine necessary permissions and documentation for inspection, identify potential digital and non-digital evidence in a work area photograph, evaluate evidence custody documentation, and outline proper storage procedures for collected evidence, emphasizing best practices for digital forensic handling and environmental security measures.

Permissions and Authorities for Searching the Work Area

Before conducting a search of Mr. Yourprop’s former workplace, it is essential to ensure I possess the appropriate permissions and legal authorities. Generally, this involves obtaining a formal warrant signed by a judge or a legal authorization from the company’s management if acting on their behalf, depending on jurisdiction and whether the investigation is internal or external. The authority must specify the scope of the search, the items to be seized, and the timeframe. Proper documentation includes a detailed search warrant or authorization letter, which records the jurisdiction, date, time, specific areas authorized for inspection, and the investigator’s credentials. Additionally, maintaining logs of the search activities, photographs of the search process, and a detailed inventory of seized items is crucial to ensure the investigation adheres to chain of custody standards, maintaining admissibility in potential legal proceedings (Casey, 2011).

Identification and Collection of Digital Evidence

In examining the provided photo of Mr. Yourprop’s work area, three potential digital evidence items are identifiable. The first is a desktop computer, which may contain user data, browser history, emails, or stored documents pertinent to the investigation. Digital evidence from a computer must be collected using write-blockers to prevent any alterations, and an image of the entire drive should be created using forensic software such as FTK Imager, following best practices to preserve the original data's integrity (Rogers, 2014). The second item is a USB flash drive lying on the desk, which could hold portable data transferred from work devices or malicious files introduced via removable media. Collection involves careful disconnection and sealing of the device in an anti-static bag, labeling it properly, and documenting the process to prevent contamination. The third item is a mobile phone on the desk, potentially containing texts, call logs, or app data relevant to the case. The phone must be properly seized, powered off to preserve volatile data, and extracted using forensic tools like Cellebrite, ensuring chain of custody protocols are strictly followed (Casey, 2011).

Identification and Collection of Non-Digital Evidence

From the photograph, three non-digital items of potential evidentiary value include a printed company email on paper, a handwritten note or memo on sticky notes, and a physical external storage device such as an external hard drive. The printed email could provide context or evidence of illicit communication or intent, and collecting it involves photograph documentation, then preserving it in a paper evidence bag, ensuring minimal handling to avoid smudging or damage. The handwritten note might contain instructions or information relevant to the case; collection involves careful removal, photographing, and securing it in an evidence bag with labels. The external hard drive, if present, might contain backups or additional files; collection includes disconnection, placement into an anti-static container, and meticulous chain of custody documentation. Proper evidence collection procedures, including avoiding contamination and ensuring secure transport, are essential for maintaining evidence integrity (Rogers, 2014).

Review of Evidence Custody Documentation

After reviewing the Evidence Custody Document prepared by a coworker, it’s important that the description of each item be precise and detailed. The document should include specific identifiers such as make, model, serial numbers for digital storage devices; detailed descriptions of physical characteristics such as size, color, and unique markings for non-digital items. Based on the photographs, I would recommend adding details such as the exact capacity, brand, and condition for the external hard drive, and including serial numbers or unique identifiers for the computer and mobile phone. For physical items, noting any damages, labels, or markings enhances traceability. For digital evidence, documenting hash values and storage locations strengthens the chain of custody and ensures integrity for court presentation. Clear, comprehensive descriptions prevent ambiguity and improve the reliability of the evidence record (Carrier, 2005).

Evidence Storage and Environmental/Security Considerations

Collected evidence must be stored in a secure, environmentally controlled evidence room to prevent tampering, deterioration, or theft. Digital evidence requires specific handling; storage should involve a secure, access-controlled environment with fire suppression systems, climate control to prevent static build-up, and proper labeling with chain of custody documentation. Evidence is best stored on read-only media or in deduplicated, encrypted repositories, with off-site backups where necessary. Non-digital evidence such as physical items should be stored in tamper-evident containers, placed in locked cabinets within a restricted access room. The environment should maintain stable temperature and humidity levels, avoiding exposure to sunlight, moisture, or vibration that might damage evidence. Security procedures must include access logs, surveillance cameras, and strict chain of custody controls to prevent unauthorized handling (Rogers, 2014; Casey, 2011). Regular audits and proper training of personnel handling evidence are essential to uphold evidentiary integrity over time.
