What Is Computer Forensics? Computer Forensics FAQ
Computer Forensics:
There are a multitude of definitions and explanations for computer forensics, however the phrase Computer Forensics is used to describe specialized techniques used for the authentication, recovery, and analysis of Electronically Stored Information (ESI). Computer Forensic techniques aid in the reconstruction of computer usage, the examination of residual data related to a crime, authentication of data by using technical analysis or explanation of technical features of data and computer usage. Computer Forensics services require properly trained investigators who go beyond the normal data collection and preservation techniques used by average end-users or IT Professionals.

Our South Florida computer forensics experts have the ability to implement all applications of digital technologies, and tools to systematically search digital devices for pertinent evidence. Digital forensics is a relatively new science. Derived as a synonym for computer forensics, its definition has expanded to include the forensics of all digital technology. Whereas computer forensics is defined as "the collection of techniques and tools used to find evidence in a computer" [Calo01], digital forensics has been defined as
"the use of scientifically derived and proven methods toward the preservation, collection, validation, identification, analysis, interpretation, documentation, and presentation of digital evidence derived from digital sources for the purpose of facilitation or furthering the reconstruction of events found to be criminal, or helping to anticipate unauthorized actions shown to be disruptive to planned operations"
Our computer forensics experts handle electronic evidence in preparation for court by the following methodology:
1. Create a forensic copy of the evidence
Gather the evidence by creating a bit by bit copy (image) of the original media.
Use only industry trusted and tested tools to void alteration of evidence media.
Never use the original media during the analysis process (unless necessary).
Always use court approved methods to establish and maintain proper chain of custody of all evidence items.
2. Evidence authentication
Provide proof of the integrity of the evidence and provide the MAC (Modified, Access, Created) times of the evidence media (when possible).
Verify the authenticity of the bit by bit image by acquiring and confirming hash values (electronic fingerprints) using industry trusted and tested algorithms (MD5 or CRC32) of the evidence to confirm that it is identical to the original.
3. Managing digital evidence chain of custody
Take photographs and record the make, model, and serial numbers of all relevant computers, hard drives, installed hardware, while documenting all attached cables and devices.
Record the time and date, list all parties present, and note any other relevant facts pertaining to the physical environment of the evidence.
Preserve the integrity of the evidence and avoid tampering by sealing the evidence in static free containers and storing them in secure, environmentally controlled, lockup.
4. Computer evidence analysis
Prepare a list of keywords and time frames relevant to the matter.
Recover erased or deleted files and documents.
Conduct file signature analysis to find altered or hidden files
Search unallocated space, swap files, hibernation files, network files and any external media for bits of evidence.
5. Trim and remove duplicates from the dataset
De-duplicate all files and filter the dataset by keywords, relevant dates, and file types.
Remove all known system files and driver files by using NIST excepted hash sets.
