Theory of Gravitational Information Security – Making Security Policy Implementation A Reality

This article draws on elements of gravity theory to help visualise information security concepts and to describe how to practically implement security policy objectives. It describes a metaphorical model where gravitational forces are analogous to the level of security controls we apply to an organisation’s information. Be warned, this will quite possibly be the nerdiest article I have written, but will be simple enough.. no degree in particle physics required to grasp it.

What is Gravity?

Gravity is a force which attracts and pulls physical objects towards each other. All objects are known to be affected by gravity, from the smallest atom to the largest star in the night sky. A general rule for gravity is, that the greater the mass of an object, the more gravitational force it will exert on the other objects around it. The sun, for instance, pulls the earth towards it in the same way that the earth pulls the moon ever closer as time passes.

At an atomic level, the closer to the center of an object we get, the greater the gravitational force is. As density increases, the movement of those central atoms is more restricted whereas the outer atoms are often able to move more freely.

The Analogy

In the same way as gravity applies force to those atoms drawing them towards the center, we can secure information by applying varying levels of enforcement based on sensitivity. If we imagine the sum of our organisation’s information as a spherical object made up of thousands of information atoms, we can start to visualize the relationship. Our most sensitive information is at the core of our infosphere (information sphere) and we must apply more force to protect it. As we move further towards the surface of our infosphere, the controls we will want to apply will be less restrictive and we will let those less sensitive information atoms move more freely.
