Current economic conditions have created many hurdles for businesses across the country as they reduce personnel, cut expenditures and seek other ways to remain viable in a competitive market. One of the biggest hurdles, resulting from the layoff of many businesses' IT employees, has been the increasing incidences of internal security breaches and the associated release of confidential data. IT departments in every company have been the gate keepers for an organization's sensitive data. Now some companies may look at these departments as an economic liability instead of an asset. Research indicated that former employees, or even disgruntled current employees, who have experienced salary reductions, been passed over for promotions, or some other perceived slight, are responsible for deliberate security breaches resulting in millions of dollars in damages, especially when they publicize the confidential data or sell it to competitors. Other breaches are caused by employee negligence, such as permitting password leaks, transmitting irresponsible social networking messages, and carelessly handling confidential data. The focus in this paper is on reference materials documenting why employees maliciously and negligently harm their employers, how companies can determine they are under attack, and what methods they can take to prevent attacks. A model is proposed recommending how companies can confront this problem, describing what policies, procedures, deterrents, and security measures can be taken to prevent such internal security breaches in the future, and how employees in each business can assist in dealing with internal threats.
