The role of encryption in securing backup data against ransomware threats

As ransomware attacks increasingly target organizations worldwide, protecting backup data has become a critical aspect of modern data security strategies. This article examines the role of different encryption techniques in defending against ransomware, ensuring that backup systems remain secure and reliable. By evaluating encryption methods such as AES, RSA, hybrid encryption, end-to-end encryption (E2EE), and file-level versus full-disk encryption, the paper underscores their effectiveness in preventing unauthorized access to backup data. The article concludes by emphasizing the necessity of a robust encryption strategy to protect backup systems from ransomware threats and maintain business continuity in the face of evolving cyber risks.
