Insider Threat
An attack from inside your organization may seem unlikely, but the insider threat does exist. Employees can use their authorized access to an organization's cloud-based services to misuse or access information such as customer accounts, financial forms, and other sensitive information.
Additionally, these insiders don't even need to have malicious intentions.
A study by Imperva, "Inside Track on Insider Threats" found that an insider threat was the misuse of information through malicious intent, accidents or malware. The study also examined four best practices companies could follow to implement a secure strategy, such as business partnerships, prioritizing initiatives, controling access, and implementing technology.
