DIGITAL FORENSICS

Computer forensics is the scientific process of capturing (imaging) and analyzing information stored in any electronic format, for the purpose of investigating allegations, to find the truth, with no predisposition as to the outcome.

 

It encompasses a number of services:

  • Disk Forensics: The process of acquiring and analyzing the data stored on physical storage media (computer hard drive, cell phones, PDAs, removable media, etc.). Disk forensics includes both the recovery of hidden and deleted data and also file identification.

  • Network Forensics: The process of examining network traffic, including transaction logs and real-time monitoring, using sniffers and tracing.

  • Internet Forensics: The process of piecing together where and when a user has been on the Internet or internal company network. This is used to determine whether inappropriate Internet content access and downloading was inadvertent or not. It is also used to determine if sensitive information was emailed inappropriately using a personal email account.

  • Email Forensics: The study of source and content of electronic mail as evidence. It includes the process of identifying the actual sender, recipient, date, time and location and from where the email originated. Email has become a significant issue for individuals and organizations. Harassment, discrimination or unauthorized activity violating company policy can be identified via email forensics.

  • Cloud Forensics: The process of acquiring and analyzing the data stored in cloud servers. CFS has conducted numerous cloud acquisitions and understands the legal and ethical considerations surrounding this form of preservation.

INCIDENT RESPONSE

CFS is capable of responding to a security incident, event, or network-type intrusion. CFS conducts a scope assessment with the client, followed by a data acquisition plan involving a variety of potential sources/devices. Once data is acquired, CFS begins its forensic analysis and investigation to obtain a comprehensive view of a suspected security breach and reconstruct event activity. CFS then utilizes the analysis data and forensic artifacts to identify any additional threats with the ultimate goal of assisting the client contain the threat(s) and begin a remediation process. CFS remains ready to provide clients with additional consultation on where gaps occurred in their security posture and work to help prevent future incidents or attacks.

DISCOVERY

Electronic discovery involves more than merely recovery of computer data. It involves proper evidence handling and preservation, sifting information through a thoughtful investigative process, and providing results in a form that can be used by a non-technical lead attorney or court. Electronic discovery is accomplished most effectively when performed in conjunction with a case strategy and an experienced forensic consultant.
