Using proven methodology and software, the electronic devices are systematically examined in an effort to recover evidence that may prove or disprove that a certain event/situation has occurred. It may show that the event occured within the device or the device
has been used to create a situation.
All examinations are carried out to the highest of standards, so that the results are evidentially sound and may be accepted in courts of law.
Digital Forensics is the process of using scientific knowledge in the collection, analysing, and presenting of evidence in court. (The word forensics means to bring to the court.) Forensics deals primarily with the recovery and analysis of latent evidence. Latent
evidence can take many forms, from fingerprints left on a window to DNA evidence recovered from blood stains to the files on a hard drive.
Computer Forensics is defined as the discipline that combines elements of law and computer science to collect and analyse data from computer systems,
networks, wireless communications, and storage devices in a way that is admissible as evidence in a court of law.

Using sound computer principles and practices, you will help ensure the overall integrity and survivability of your network infrastructure. You can help your organisation if you consider computer forensics as a new basic element in what is known as a
defence-in-depth approach to network and computer security. Understanding the legal and technical aspects of computer forensics will help you capture vital information if your network is compromised and will help you prosecute the case if the intruder is caught.
