SEC01-BP03: Identify and validate control objectives
Based on your compliance requirements and risks identified from your threat model, derive and validate the control objectives and controls that you need to apply to your workload. Ongoing validation of control objectives and controls helps you measure the effectiveness of risk mitigation.
Implementation guidance
Control objectives are the specific goals and outcomes that your security controls are designed to achieve. By identifying and validating these objectives, you can ensure that your security controls are effective and aligned with your compliance requirements and risk management strategy.
Key steps for implementing this best practice:
- Identify compliance requirements:
- Determine which regulatory frameworks apply to your workload (e.g., GDPR, HIPAA, PCI DSS)
- Identify industry standards relevant to your organization (e.g., ISO 27001, NIST CSF)
- Document internal security policies and requirements
- Map compliance requirements to specific control objectives
- Conduct threat modeling:
- Identify potential threats to your workload
- Assess the likelihood and impact of each threat
- Prioritize threats based on risk
- Determine which controls are needed to mitigate identified threats
- Define control objectives:
- Create clear, measurable control objectives based on compliance requirements and threat model
- Ensure control objectives are specific, measurable, achievable, relevant, and time-bound (SMART)
- Align control objectives with your organization’s risk tolerance
- Document the relationship between control objectives and specific risks
- Implement security controls:
- Select controls that address your control objectives
- Implement technical, administrative, and physical controls as needed
- Document how each control maps to control objectives
- Ensure controls are properly configured and functioning
- Validate controls:
- Test controls to ensure they function as expected
- Conduct regular assessments of control effectiveness
- Use automated tools to continuously validate controls where possible
- Perform penetration testing to identify control weaknesses
- Monitor and improve:
- Continuously monitor control performance
- Regularly review control objectives and controls
- Update controls as threats and compliance requirements evolve
- Implement a continuous improvement process for security controls
Control frameworks and standards
Several established control frameworks can help you identify and validate control objectives:
NIST Cybersecurity Framework (CSF)
The NIST CSF provides a policy framework of computer security guidance for organizations to assess and improve their ability to prevent, detect, and respond to cyber attacks. It consists of five core functions:
- Identify
- Protect
- Detect
- Respond
- Recover
ISO/IEC 27001
ISO/IEC 27001 is an international standard for managing information security. It specifies requirements for establishing, implementing, maintaining, and continually improving an information security management system (ISMS).
CIS Controls
The Center for Internet Security (CIS) Controls are a set of 18 prioritized safeguards to mitigate the most common cyber attacks. They are organized into three implementation groups based on their complexity and resource requirements.
AWS Shared Responsibility Model
The AWS Shared Responsibility Model defines the security responsibilities of AWS and its customers. AWS is responsible for “security of the cloud,” while customers are responsible for “security in the cloud.”

Benefits of identifying and validating control objectives
- Aligned security controls: Ensures security controls are directly tied to specific risks and compliance requirements
- Measurable security posture: Provides clear metrics for evaluating security effectiveness
- Efficient resource allocation: Focuses security investments on the most important control objectives
- Simplified compliance: Makes it easier to demonstrate compliance with regulatory requirements
- Improved risk management: Provides a structured approach to managing security risks
- Enhanced security governance: Establishes clear accountability for security controls
