Security research requires specific definitions to assure that meaning is properly conveyed. The development of the Open Source Security Testing Methodology Manual (OSSTMM) required hundreds of researchers and thousands of reviewers working together to create a significant piece of work. The first major hurdle to overcome was agreeing on common definitions for terms. The word protection became the common synonym for security since it had fewer outside connotations. However, the idea that security meant freedom from risk stuck with the developers of the project and, in effect, tainted the research.
Early versions of the OSSTMM, through version 2.X, used common definitions; however, early versions also focused on risk. Researchers disagreed about these definitions while developing those early versions. A security standard has no room for disagreement. People expect a security standard to be black and white. It needs to be correct and factual. To do that, it needs to avoid the concept of risk.
Risk is biased. People accept risk at varying rates. Furthermore, the dictionary definition of security being "freedom from risk" is an impossibility since even our own cells may conspire against us. Therefore, "freedom from risk" is not something that can be effectively or realistically used to understand security, let alone to measure it. The researchers realized that the concept of risk could not be in the OSSTMM.
The OSSTMM researchers determined that security in its simplest form is not about risk, but about protection. This is why they referred to protection when discussing security. They concluded that security could be best modeled as the "separation of an asset from a threat." This theme has become universal when discussing security whether it be Internet fraud, petty larceny, or creating a retirement fund. In each case, security separates the asset from the threat. Not surprisingly, the best defense from any threat is to avoid it, by either being far removed from it or having it removed.
Security is the separation of an asset from a threat.
Security as practiced by the military generally means destroying the threat. A nonfunctioning threat is no longer a threat. So to separate the threat from the asset, you have three options:
• Physically remove or separate the asset from the threat.
• Move or destroy the asset.
In practical terms, destroying the asset is undesirable and destroying the threat is often too complicated or illegal. However, separating the two is normally achievable.
