Security Design

Building a system that requires multiple levels of authentication before a record can be accessed limits the pool of potential actors. This design often includes encryption and physical locks on servers to prevent local access. By creating these barriers, the company reduces the risk of an internal threat.

Modification Detection

When a change is attempted on a protected file, the system must trigger an alert or leave a visible mark of the event. This detection mechanism relies on the mathematical properties of the data or the physical properties of the storage medium. If a person tries to change the date on a digital contract, the security software identifies the inconsistency and prevents the file from being saved.

This immediate response is a major deterrent for anyone considering fraud. The resulting log of these attempts provides the management team with a list of security risks that need to be addressed.

Audit Security

Providing a record that is known to be accurate allows for a faster and less expensive review by external experts.
