What is Data Leakage?
Data Leakage occurs when sensitive information is exposed in an unauthorized manner. From another angle, it involves the failure to protect such information, and it can lead to data loss or data theft.
How to Recognize This Threat: The threat of data leakage is especially great when data is shared between multiple management applications within an organization, such as Human Resources, CRM, and Accounting tools.
How to Prevent This Threat: Access Control Lists, encryption, and generally strong internal network security are a must. A cornerstone of network security is a robust firewall, through which all traffic should be managed. See excellent firewall options from a variety of top brands.
