When Processing A Crime Scene That Contains Cyber Evidence

When Processing A Crime Scene That Contains Cyber Evidence There Are

When processing a crime scene that contains cyber evidence, there are three main categories of evidence. Areas to be searched may be obvious, such as a desk with a computer on it or drawers containing computer-related material. Other areas, such as suspended ceilings and adjacent rooms, may also be important. Local Area Networks (LANs) will often connect multiple computers, tablets, and smartphones to each other. Devices supporting connections and power backup may also be concealed in suspended ceilings, behind panels, or in adjacent rooms or closets.

Research and identify the following types of evidence that may be found in a multi-computer crime scene and should be seized: Category 1: Hardware—physical devices that compute, store virtual files, scan, or print. Category 2: Software—programs that can be loaded onto hardware to perform functions; software alone cannot do anything. Category 3: Items necessary to set up the seized hardware in the same configuration as at the crime scene, including power sources, connection cables, and wireless connection devices.

List three items of evidence from each category and briefly identify their function. Use your text, web resources, and all course materials for assistance.

Paper For Above instruction

In the investigation of cyber-related crimes, methodical collection and preservation of evidence are critical to ensure the integrity of the case and adherence to legal standards. The process involves a thorough search of the crime scene to uncover physical devices, digital systems, and supporting infrastructure that could hold relevant evidence. This paper discusses the categories of evidence that should be seized during a crime scene investigation involving cyber evidence, specifically hardware, software, and setup materials required to replicate the scene’s digital environment accurately.

Category 1: Hardware

Hardware encompasses the physical devices present at the scene that facilitate computing and storage functions. Three crucial examples include:

  1. Computer Towers or Laptops: These are the primary devices used by suspects or victims to perform digital activities. They store virtual data, run applications, and may contain relevant logs or files pertinent to the investigation.
  2. External Storage Devices (USB drives, External Hard Drives): These portable devices are often used to copy, transfer, or back up data. They are critical for retrieving deleted files or transferring data to secure locations.
  3. Network Equipment (Routers, Switches): These devices manage digital communications within the scene and may contain configurations, logs, or firmware information relevant to network-based crimes.

Category 2: Software

Software refers to the programs and operating systems loaded onto hardware that enable digital operations. Identifying relevant software can provide insights into the suspect’s activities and potential malicious tools. Examples include:

  1. Operating Systems (Windows, macOS, Linux): These platforms facilitate user interaction and run the applications involved in the crime. Analyzing the OS can reveal system logs or history files useful to the investigation.
  2. Malware or malicious tools: These may include viruses, spyware, or ransomware installed to compromise data integrity or facilitate unauthorized access.
  3. Encryption or security tools (VPN clients, encryption software): These applications may be used to anonymize activities or secure data, important for understanding methods used by the perpetrator.

Category 3: Setup Materials

To accurately replicate the digital environment, investigators need to gather specific items that support the physical and wireless installation of the seized devices. This ensures proper analysis and forensic recovery. Examples include:

  1. Power Sources (AC adapters, batteries): Essential to ensure the devices can function during analysis and testing.
  2. Connection Cables (Ethernet, HDMI, USB): Necessary for establishing network connections or displaying visual output during setup.
  3. Wireless Connection Devices (Wi-Fi adapters, access points): Important for re-establishing wireless networks or testing device communications in controlled environments.

Conclusion

Effectively processing a cyber crime scene requires careful identification and seizure of various evidence types, spanning physical hardware, digital software, and setup materials. Collecting and preserving these items in their original context is vital for reconstructing the incident, understanding the methods employed by perpetrators, and providing legally admissible evidence. An organized approach increases the likelihood of successful investigation and prosecution of cyber crimes.
