These measures ensure the security and integrity of sensitive payment information, shielding it from potential threats and unauthorized access.

Health Insurance Portability and Accountability Act (HIPAA)

HIPAA guarantees the security of sensitive health records overseen by healthcare entities. Compliance requires companies to regularly assess risks and implement risk management policies. These measures uphold the confidentiality and integrity of individuals’ health information, ensuring it remains protected from unauthorized access or breaches. 

General Data Protection Regulation (GDPR)

GDPR prioritizes the protection of personal data gathered and handled by organizations within the European Union. It establishes fundamental rights, including access, rectification, erasure, and notification in the event of data breaches. Here is a breakdown of all the user rights highlighted under GDPR.

• Right to Access: Individuals have the right to obtain confirmation from organizations about whether their personal data is being processed. They can request access to their personal data and information about how it is being used by the organization.

• Right to Be Informed: Individuals have the right to be informed about the collection and use of their personal data. Organizations must provide clear and transparent information about the purposes of data processing, the categories of data being processed, and any third parties involved.

• Right to Modify: Users have the right to request the correction of inaccurate or incomplete personal data held by organizations. If the data is found to be incorrect or outdated, organizations must promptly update it to ensure its accuracy.

• Right to Erasure (Right to Be Forgotten): Individuals have the right to request the deletion or removal of their personal data when there is no compelling reason for its continued processing. This right enables individuals to have their data erased under specific circumstances, such as when the data is no longer necessary for the purposes for which it was collected.

• Right to Data Portability: Users have the right to receive their personal data in a structured, commonly used, and machine-readable format. They can also request the transfer of their data from one organization to another, without hindrance from the original organization.

• Right to Object: Individuals have the right to object to the processing of their personal data in certain situations, such as direct marketing or processing for purposes of scientific or historical research. Organizations must respect these objections and cease processing the data unless they have legitimate reasons for continuing to do so.

• Right to Restriction of Processing: Users have the right to request the restriction of processing of their personal data under certain circumstances. This right allows individuals to limit the ways in which organizations can use their data while unresolved issues are being addressed.

• Right to Notification of Data Breach: Individuals have the right to be notified without undue delay if their personal data is involved in a data breach that poses a risk to their rights and freedoms. Organizations must inform affected individuals about the nature of the breach, the potential consequences, and any measures taken to mitigate its impact.

ISO 27001

ISO 27001 serves as a global benchmark for information security management systems, applicable across diverse cloud solutions. Emphasizing key aspects such as risk assessment, asset management, access control, incident response, and continuous monitoring, provides a systematic approach to ensuring strong security measures. 

Other than ISO 27001, ISO has two other compliance frameworks which include:

• ISO/IEC 27002: Also known as ISO 27002, is a standard that complements ISO/IEC 27001 by providing guidance on implementing specific security controls outlined in ISO 27001. It details best practices for information security management and offers recommendations for protecting sensitive data and mitigating security risks.

• ISO/IEC Technical Report 22678: This technical report provides guidelines for cloud service providers and cloud customers on implementing cloud security policies. It offers insights into various aspects of cloud security, including access control, data protection, and compliance requirements.

NIST Cybersecurity Framework

The NIST Cybersecurity Framework, developed by the National Institute of Standards and Technology (NIST), provides comprehensive guidelines for identifying, protecting, detecting, responding to, and recovering from cybersecurity risks. Specifically tailored for cloud environments, it emphasizes the assessment, mitigation, and management of cybersecurity risks. 

Here are a few other sub-categories other than the NIST Cybersecurity Framework:
