Abstract	The rapid expansion of digital information systems has transformed the manner in which organizations create, store, process, exchange, and manage information. Enterprise applications, cloud platforms, mobile technologies, Internet of Things devices, artificial intelligence systems, and interconnected digital services have created substantial opportunities for operational efficiency and innovation. At the same time, these developments have expanded the cyber threat landscape and increased organizational exposure to unauthorized access, malware, ransomware, phishing, insider threats, data breaches, denial-of-service attacks, supply-chain compromises, and sophisticated persistent attacks. Cybersecurity frameworks provide structured approaches for identifying, assessing, managing, monitoring, and responding to these risks. This study examines cybersecurity frameworks for protecting digital information systems and develops an integrated conceptual framework for strengthening organizational information security. A conceptual and descriptive research design was adopted through a thematic synthesis of scholarly literature related to cybersecurity governance, information security management, risk assessment, security controls, incident response, identity management, privacy protection, threat intelligence, and organizational resilience. The analysis demonstrates that effective cybersecurity protection requires a multilayered approach combining governance, risk management, preventive controls, detection mechanisms, incident response, recovery capabilities, and continuous improvement. Security frameworks provide organizations with structured mechanisms for establishing security policies, identifying critical assets, evaluating threats, implementing controls, and monitoring security performance. Identity and access management, encryption, network segmentation, endpoint protection, secure configuration, vulnerability management, security monitoring, and employee awareness are identified as important components of digital-system protection. The study further proposes an integrated cybersecurity framework consisting of asset identification, risk assessment, protection, detection, response, recovery, and continuous evaluation. The analysis indicates that cybersecurity maturity depends not only on technological controls but also on leadership commitment, governance structures, employee awareness, third-party risk management, security culture, and organizational preparedness. Major challenges include increasingly sophisticated cyberattacks, complex digital infrastructures, legacy systems, shortage of cybersecurity professionals, inconsistent security practices, supply-chain dependencies, privacy requirements, and limited organizational resources. The study concludes that cybersecurity frameworks should be implemented as continuous organizational processes rather than static compliance mechanisms. An integrated framework combining technical, managerial, human, and governance dimensions can improve the confidentiality, integrity, availability, resilience, and trustworthiness of digital information systems. Future research should examine adaptive cybersecurity frameworks, artificial intelligence-based threat detection, zero-trust architectures, autonomous incident response, privacy-preserving security analytics, and predictive cyber-risk management.
