Social Media Forensics: A Primer
A brief overview of the technical, legal, and practical issues in a social media investigation.
Specialized hardware, software, and knowledge is required, so most collection or preservation efforts will require a digital forensics expert. In addition to the data that is visible directly on the site, an expert can often collect other data, such as private posts and metadata, that may not be accessible through the normal user interface.
After capturing the data, a social media forensics expert can also make the data more useful to an attorney or investigator, enabling comprehensive keyword searches and allowing for review of the data in a format that emulates the original post.
