What is a significant challenge when using converged protocols in enterprise-wide security?

The need for additional specialist knowledge is a significant challenge associated with the implementation of converged protocols in enterprise-wide security. Converged protocols combine different types of data (like voice, video, and data) over a single network. This integration can lead to complex security requirements that go beyond traditional IT security measures.

Organizations need to understand how to secure communication across different media and ensure that security protocols are effective across all types of integrated services. This often requires specialized knowledge in areas such as network design, risk management, and specific security mechanisms applicable to converged environments. Moreover, IT staff may need training or certification in these areas to effectively manage and secure the more advanced protocols.

In contrast, while increased operational costs, malfunctioning hardware, and compatibility issues with applications may also pose challenges in deploying converged protocols, they are less directly related to the specialist knowledge required for securing those environments effectively. Thus, the need for expertise stands out as a primary challenge in the context of enterprise-wide security using converged protocols.
