Abstract
Backup systems are an essential part of data protection, ensuring that businesses can recover from data loss caused by accidental deletions, hardware failures, or cyberattacks. However, these systems are often overlooked when it comes to security, making them vulnerable to a range of risks. As organizations increasingly depend on backup data for continuity, addressing the vulnerabilities in these systems is critical. This study highlights common security threats like ransomware, insider attacks, and unauthorized access, and examines how advanced measures—such as encryption, Multi-Factor Authentication (MFA), and Role-Based Access Control (RBAC)—can mitigate these risks. Encryption secures backup data, MFA enhances authentication procedures, and RBAC restricts user access to minimize the impact of internal threats. The paper evaluates the effectiveness of these measures, discusses implementation challenges, and offers best practices for improving backup system security. The aim is to provide a roadmap for organizations to protect their backup infrastructure against evolving cyber threats.
