Incident Response and Digital Forensics

Digital forensics typically comes into play as a subset of incident response, and it is generally reserved for incidents that have the potential to end up in a civil or criminal court. Incident response teams are typically ill-prepared to manage incidents of this nature, resulting in organizations choosing to contract with external experts when serious incidents occur. The challenge for most organizations is being able to identify these differences early on, so that those with the proper expertise do not arrive to find that important evidence has been disturbed or destroyed by untrained technicians, no matter how well-meaning they may be. Using external expertise for forensics investigations also makes sense, due to the complexity and specificity of the tools and procedures used by these experts to ensure that evidence is discovered and is collected using proper chain of custody. Networks that are not properly managed, or on which robust and effective security controls are implemented, create difficult environments for forensics experts, as they try to perform their work in a way that will be appropriate for use in a court of law.
