The primary reason for the implementation of additional security controls is to manage risk to acceptable tolerance levels. Here's the explanation:
* Avoid the Risk of Regulatory Noncompliance: While compliance is important, the primary driver of security controls is broader than just compliance. It is about managing overall risk, which includes but is not limited to regulatory requirements.
* Adhere to Local Data Protection Laws: This is a specific aspect of risk management related to compliance. However, the broader goal of implementing security controls is to address a wide range of risks, not just those related to legal compliance.
* Manage Risk to Acceptable Tolerance Levels: The fundamental purpose of implementing additional security controls is to ensure that risks are reduced to levels that are acceptable to the organization. This encompasses regulatory compliance, data protection, operational continuity, and overall security posture.
Therefore, the primary reason is to manage risk to acceptable tolerance levels.
