ABSTRACT
One of the foremost small business security concerns is the protection of critical information, both within their internal financial infrastructures and from external elements, Studies show that most cyber-attacks occur inside organizations, instigated by personnel with valid access to the system. This paper describes the design, implementation, and testing of security system that enhances the capability of small businesses to protect information within the boundary of their networks. Within a specified network, database and transactions are encrypted, decrypted, and processed by the Internal Control and Employee Agents. The database was clustered and access method was provided to employees using private keys. The test results indicate that this additional security layer provides a simple solution to the data sharing and transition within an organization’s network. The results of this study will be of significance to owners, managers, and the security personnel responsible for small business networks.
