Security threat protection strategies: development of a cybersecurity system

Objective. The relevance of this study stems from the rapid advancement of the digital economy and the escalating cyber threats that jeopardize the security of personal data and financial transactions. The aim of the scientific research is to analyze modern strategies for protecting against cyber threats and to advance the development of a cybersecurity system in the context of digital transformation. Method . Research methods encompass literature review, statistical analysis, and case studies. Result . The paper considers the types of cyberattacks (phishing, DDoS, malware, cyber espionage) and key security technologies, including AES-256 encryption, multifactor authentication (MFA), and intrusion detection systems (IDS). Attention is paid to the following strategies: proactive defense, adaptive security, and zero trust architecture, with examples of their application in Russia (Sberbank, Rostelecom, medical institutions). The paper studies the mechanisms for preventing attacks and increasing cyber resilience, including the role of GosSOPKA, which processed over 500 thousand incidents in 2023. The paper identifies system vulnerabilities and proposes ways to minimize them: upgrading technical equipment, developing human resources, and improving the regulatory framework. Conclusion . The practical significance lies in the development of recommendations for the implementation of strategies that reduced damage from attacks by 18% in 2023. A systematic approach is needed to integrate innovations and coordinate efforts to ensure sustainable development of cybersecurity in Russia.
