ABSTRACT

As enterprises become increasingly dependent on the Internet, there is a growing trend among firms to open their network infrastructures to key stakeholders, including customers, employees, partners, and suppliers. By opening the enterprise environment to improve information flow and transaction capabilities, the inherent risks and vulnerabilities significantly increase as well. As a result, it is critical for enterprises to provide a secure environment that guarantees stakeholders the confidential exchange of information while ensuring data, message, and transaction integrity.
