Security falls under?

The aspect of security testing primarily aligns with compliance testing because it involves ensuring that software systems adhere to specific security standards, regulations, and guidelines. Compliance testing aims to validate that the system meets the required legal and regulatory requirements related to security, data protection, and privacy. It not only checks adherence to these standards but also evaluates whether the required security controls and measures are effectively implemented and maintained.

Additionally, compliance testing in the context of security often encompasses frameworks and protocols that organizations must follow, such as GDPR, PCI DSS, or HIPAA, depending on the industry. Ensuring compliance helps mitigate risks related to security breaches and fosters a trustworthy environment for users and stakeholders. This makes it crucial in the broader scope of software quality assurance, where security is considered a fundamental aspect of the system's overall quality.
