Protection of confidential data in Amazon Elastic Block Store snapshots

Abstract

The article examines security issues in an Amazon Web Services (AWS) environment with an emphasis on the risks associated with public Elastic Block Store (EBS) snapshots. Analyzes how user identification and authorization processes can contribute to security risks and leakage of confidential data. Methods for detecting and monitoring public snapshots are described in detail, as well as recommendations for changing permissions and ensuring the security of credentials. Emphasizes the importance of conducting investigations when public snapshots are discovered, and develops strategies to prevent such incidents, including staff training and enforcement of privacy policies. AWS's approach to security is highlighted, particularly through informing customers about the potential risks associated with public access to snapshots. The paper offers a comprehensive overview of security issues in an AWS environment, focusing on data management, and recommends specific measures to ensure the secure use of EBS snapshots. Potential vulnerabilities are illustrated with real-world examples, demonstrating the importance of properly managing access policies and the informed use of snapshots to prevent accidental data leakage. Particular attention is paid to the impact of open snapshots on various industries and the need for audits to identify potential threats.
