NIST SP 800-30
This publication, also developed by NIST, provides a more detailed set of security controls focused on protecting Federal Information Systems and Organizations (FISMA). It can be used to supplement NIST CSF by providing specific controls for each of the five core functions. There are different variations of SP 800-30 that target specific security areas, such as Special Publications for Risk Assessments or Security and Privacy Controls for Federal Information Systems and Organizations.
Benefits: NIST SP 800-30 offers a comprehensive set of controls that can be tailored to an organization's specific needs. By implementing these controls, organizations can improve their overall cybersecurity posture and meet FISMA compliance requirements.
Drawbacks: NIST SP 800-30 can be complex and difficult to implement for organizations without significant cybersecurity expertise. Additionally, complying with all the controls can be resource-intensive.
SOX 404 (Sarbanes-Oxley Act Section 404)
This is a regulatory compliance framework established by the Sarbanes-Oxley Act. It focuses on internal controls over financial reporting. While not strictly a cybersecurity framework, SOX 404 includes controls that can help to mitigate cybersecurity risks that could impact the accuracy of financial reporting.
Benefits: SOX 404 compliance can help to ensure the accuracy and reliability of financial reporting. This can improve investor confidence and reduce the risk of financial fraud. Additionally, some of the controls implemented for SOX 404 can have broader cybersecurity benefits.
Drawbacks: SOX 404 compliance can be expensive and time-consuming, particularly for larger organizations. The focus on financial reporting may not address all of an organization's cybersecurity risks.
CIS Critical Security Controls (CIS CSC Top 20)
This framework, developed by the Center for Internet Security (CIS), is a free and non-vendor specific set of high-impact controls that can be implemented by organizations of all sizes and industries. The CIS Controls are designed to address the most common cyber threats and vulnerabilities. There are different versions of CIS Controls tailored to specific environments, such as CIS Controls for Enterprise or CIS Controls for Smaller Organizations.
Benefits: CIS Controls are a cost-effective way to improve an organization's cybersecurity posture. They are easy to understand and implement, and they are aligned with other popular frameworks, such as NIST CSF.
