The Issue of Network Content Monitoring Network content monitoring and filtering is an appliance based technology often used to protect information from escaping over a companies network. These solutions are often deployed as part of a defense in depth strategy, but do not offer the completeness of protection that is often expected. Network content monitoring and filtering systems are unable to: - Protect most data that is encrypted
- Protect data that moves through networks using tunneling like Microsoft's PPTP technology
- Protect data that is on mobile devices
- Protect data that is copied from an endpoint to an external device
Implementing this technology alone is an incomplete DLP solution that protects only a small portion of data in use or in motion. |
