Fundamental Principles of Cybersecurity in The Software Testing Process

The study examines the principles of ensuring cybersecurity during software testing. The focus is placed on the fact that testing should not be limited to validation checks but must also incorporate risk assessment, compliance with standards, and early-stage vulnerability analysis throughout the software development lifecycle. The study reviews key regulatory requirements (GDPR, HIPAA, PCI DSS, ISO/IEC 27001, NIST Cybersecurity Framework) and analyzes their impact on testing strategies and quality control processes. Special attention is given to the CIA triad (confidentiality, integrity, and availability) and proactive incident planning. The necessity of integrating automated tools (SAST/DAST, SIEM, RPA, etc.) and artificial intelligence algorithms is substantiated to optimize protection procedures and enhance vulnerability detection efficiency. The conclusions emphasize that achieving a high level of product resilience is only possible through the close alignment of security requirements with test scenarios and the continuous refinement of testing methodologies. The findings presented in this study will be of interest to researchers and professionals in information security, softw
