Another meaningful categorization of fraud crimes is internal and external.Internal crimes are far greater in number. In fact, the most common type of computer crime is probably theft of assets by employees. They have fraud opportunity from being inside the organization; with some pressure to steal (personal cash flow problems) and weak personal ethics,the fraud triangle is complete. If a weakness exists in the controls, the temptation can become too great for the employee to resist stealing from the organization. Then there are those who break in from the outside to steal data, sabotage systems,or spy. Others bring a system down and make it unavailable to users. Whatever the damage, these actions intentionally bring about losses and as such are computer-related crimes.
