What are

Digital
Forensics?

Digital forensics has many different definitions depending on the content and industry.
According to the United States Department of Defense, digital forensics is "the application of computer science and investigative procedures involving the examination of digital evidence - following proper search authority, chain of custody, validation with mathematics, use of validated tools, repeatability, reporting, and possibly expert testimony." (DoDD 5505.13E)

According to the National Institute of Standards and Technology (NIST), digital forensics is "application of science to the identification, collection, examination, and analysis of data while preserving the integrity of the information and maintaining a strict chain of custody for the data." (NIST, NIST SP 800-86). Forensic science is "the application of a broad spectrum of sciences and technologies to the investigation and establishment of facts of interest in relation to criminal law, civil law, or regulatory issues. (NIST, NISTIR 8006).  NIST also defines it as "the application of science to the law." (NIST, NIST SP 800-86)
VLS defines digital forensics as the identification, preservation, collection, examination, and documentation of digital evidence that may be presented in a civil, criminal, or administrative litigation or process. If the evidence is not going to be presented in a court, litigation hearing, or a part of an administrative process, then we don't consider the process to be digital forensics.

So what does this mean? It means different things depending on your perspective. For a law enforcement officer, it means that when investigating any crime you should be looking for digital evidence that may be probative because it could be incriminating or exculpatory in nature.  According to the International Association of Chiefs of Police (IACP), every crime has a digital nexus.  That means every case you are investigating has digital evidence that could prove or disprove your case.  This could include common digital evidence items like ones seen below:

4C Forensics is a private crime lab. Specialists in digital evidence identification, collection, transportation, storage, analysis, and reporting.Subsidiary of Veterans Lab Services, Inc. (a Texas Corporation.) The 4Cs of digital evidence that we primarily specialize in are: Computers, Cellphones, Cars, and Canines (4C).  4C is a service-connected and permanently disabled veteran-owned small business.Our mission…provide the highest standards and technical expertise to our customers so they achieve mission success.Customers include law enforcement, government agencies, law firms, and private individuals involved in civil, criminal, or administrative litigation.

THE VLS
PROCESS

First and  foremost, our Team always operates under the proper search authority…search warrant (if our client is a law enforcement agency), a contract/task order (if we are working with a government agency), or a service agreement if we are working with a private client. Equally at home with high profile or top secret data.

Respecting the law is a priority as is EVERYONE’S privacy interests, and we only perform work that is duly authorized.  

PHASE 1:

Identification

The first step is identifying and finding digital evidence.  <We> provide a unique service because we are the only private crime lab that provides electronic storage device (ESD) detection K9s.  Our ESD K9s are specially trained to identify and detect hidden, obscured, and covertly placed digital evidence.  Trained customers that conduct crime scene searches, or primary searches affiliated with a search warrant, miss and overlook key pieces of digital evidence that is probative to your case.  It has been documented that secondary searches that utilize ESD K9s identify and located digital evidence in over 28% of the time - when trained human searches are utilized during primary searches.  In the case of investigations involving CSAM (child sexual abuse material), without utilizing ESD K9s you  could be missing digital evidence that could have images and videos of real victims that you may not know about.  You could also be overlooking digital evidence that connects other cases that you are not aware of.

PHASE 2:

COLLECTION

Do you know how to properly collect digital evidence?  Did you know that the order in which you collect digital evidence is vital to your case?   <We> have the resources to train you on the proper collection, and are available to provide onsite assistance at crime scenes and search warrants when necessary.

PHASE 3:

PRESERVATION

The goal to any forensic investigation is to maintain the integrity of the evidence.  This is no different when collecting, storing, and analyzing digital evidence.  How you collect, package, transport, store, and handle digital evidence directly impacts if it will be properly preserved.

PHASE 4:

ANALYSIS

Do you know that how you analyze digital evidence impacts the quality of your results. Do you know when to analyze 'live' digital evidence from a system that is turned on? What about how you copy digital evidence during your analytical process?

Listed below are key facts and insights about the VLS Crime Lab.

For more details, please Contact VLS.

Our crime lab is PRIVATE and full service = independent, third party analysis of digital evidence.

Law enforcement labs can have a bias towards the prosecution.

Because we are private, we can work for the prosecutor, defense, or private party.  We do not have jurisdictional boundaries.

International accreditation* through ANAB under the ISO 17025 standard. 1 of only 2 private accredited labs that can support any customer.

ISO 17025 = competence; results are valid and repeatable based on our established quality manual, policies, procedures, and guidelines.

Subject matter experts. Most of the 17,000+ law enforcement agencies in the United States without an internationally accredited digital forensics lab, do not have experts in the field of digital forensics. They have personnel with general understanding and training, but may not be able to qualify as a subject matter expert if their work product was ever scrutinized in a court of law.

Lab director is recognized as an expert in digital forensics.  He teaches digital forensics for a nationally accredited digital forensics program where he trains and mentors the new generation of digital forensic investigators.

Licensed private investigators. In some jurisdictions, digital forensics personnel must possess private investigation licenses. *pursuing
