When an IT governance committee is reviewing its current risk management policy due to increased usage of social media within an enterprise, the first task should be to initiate an assessment of the impact on the business. This assessment will provide a comprehensive understanding of how social media usage affects various aspects of the business, including productivity, security, data privacy, and compliance with existing policies and regulations. Understanding the business impact will inform the committee's decisions on any necessary policy adjustments or controls to mitigate potential risks associated with social media usage. While reviewing current usage levels, blocking access, and reassessing BYOD policies are relevant considerations, they should be informed by an initial assessment of the business impact to ensure that any actions taken are aligned with the enterprise's strategic objectives and risk tolerance.
