SCP (Security Control Plan)

What is SCP (Security Control Plan)?

A Security Control Plan (SCP) is a formal document that details the security controls implemented or planned to be implemented within a specific information system or organization. In the context of government contracting, SCPs are often required to demonstrate compliance with federal security mandates, protect sensitive government data, and secure information systems that process, store, or transmit government information.

Definition

An SCP provides a comprehensive overview of an organization’s security posture regarding a particular information system. It identifies the security controls in place, how they are implemented, and how they are monitored and maintained. These controls can include technical safeguards (e.g., firewalls, intrusion detection systems, encryption), administrative procedures (e.g., security awareness training, access control policies), and physical security measures (e.g., facility access controls, environmental protection). The need for an SCP often stems from regulations like the Federal Information Security Modernization Act (FISMA), the National Institute of Standards and Technology (NIST) guidelines (e.g., NIST SP 800-53), and Cybersecurity Maturity Model Certification (CMMC). For government contractors, a well-developed and maintained SCP is crucial for securing contracts, demonstrating compliance, and mitigating the risk of data breaches and security incidents.

Key Points

• Control Implementation Details: The SCP should detail how each security control is implemented, including specific configurations, procedures, and responsibilities.
• Compliance Mapping: The plan must map the implemented controls to the specific requirements of relevant security standards and regulations (e.g., NIST 800-53, CMMC levels).
• Continuous Monitoring: The SCP should outline the processes for continuously monitoring the effectiveness of the security controls. This includes regular assessments, vulnerability scanning, and incident response procedures.
• Regular Updates: The SCP must be kept up-to-date to reflect changes in the information system, security threats, and regulatory requirements. This often involves periodic reviews and revisions.

Practical Examples

1. FedRAMP Compliance: A contractor bidding on a project requiring FedRAMP authorization needs to develop an SCP that demonstrates how their cloud service offerings meet FedRAMP security requirements. This SCP will be reviewed by a Third-Party Assessment Organization (3PAO) during the assessment process.
2. CMMC Certification: A Department of Defense (DoD) contractor seeking to achieve a specific CMMC level must create and maintain an SCP that outlines the implementation of the required security controls. The SCP will be assessed by a certified CMMC assessor.
3. Controlled Unclassified Information (CUI) Protection: If a contractor handles CUI, the SCP must detail how the CUI is protected in accordance with government regulations, such as those outlined in 32 CFR Part 2002. This includes controls for access control, encryption, and data handling.
