What is an information security expert witness?
Information security expert witness candidates typically have extensive experience and expertise in computer science, information security, cyber security, and/or computer forensics. An information security expert witness should also feel confident explaining digital evidence and technology to a jury. In a high-profile case, or litigation involving a significant financial stake, a law firm may request an information security professional with prior expert witness testimony experience.
What types of cases require an information security expert witness?
Information security is the practice of preventing unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction of physical or electronic information. Information security programs are commonly built around CIA (Confidentiality, Integrity and Availability).
A computer forensics expert can reverse engineer components to prove (or disprove) intellectual property infringement, theft, or cybercrime.
