Often computer fraud and misuse can be difficult to detect. Helping companies to identify computer and mobile phone abuse in the workplace is essential in combating the accessing of inappropriate websites, computer fraud and the loss of Intellectual Property. The industry of computer crime investigation as a result has continued to grow, and many clients are turning to investigations specialists to provide expert guidance in identifying whether any misuse has occurred.
These companies should follow all Association of Chief Police Officers (ACPO) guidelines on handling and preserving digital evidence and be ISO9001 and ISO27001 certified. ISO 17025 will also soon be a requirement. Alongside undertaking their own investigations many will also work with other organisations' in-house computer teams to assist with complex tasks that these companies may not have the resources or knowledge to undertake internally.
A mobile phone forensic investigation uses techniques consistent with ACPO standards to retrieve text and picture messages, call logs, photos, videos, internet history, address books and any other types of associated information that could be utilised in an examination.
Any forensic phone investigator should work from a properly certified mobile phone forensic lab, and the team of analysts should be specialists in the varying types of phone hardware and software. They should also be aware that each phone model is different, and requires a targeted, specific technique for forensic purposes.
All computer misuse investigations should be handled properly and comprehensively to eliminate the threat of legal challenges. This may, for example follow allegations of intellectual property theft or inappropriate use of company computers that could lead to contract terminations.
If the situation should arise, always contract a team that can give expert witness evidence in court or at a tribunal, and outline the processes and procedures involved in the investigation and any conclusions that were reached. The company should have a proven track record in delivering professional expert witness services in court - ensuring that any highly technical issues that form part of the examination are presented in an easily understood way.
In a computer crime investigation, communication is key. Clients should expect regular updates and, following completion of the examination, the analyst should present their clients with a jargon-free document detailing the extent of computer misuse, if any, that has been found.
