Securing Access in Cloud Environments using IAM

1. Securing Access in Cloud Environments Exploring Cross-Chain and Dynamic IAM Access Control Aditya Devarahalli Nanjappa MSCE - 630

2. Abstract As businesses migrate to the cloud, securing access to resources becomes critical. IAM is pivotal for ensuring confidentiality, integrity, and availability. This slides delves into IAM in cloud environments, its components, challenges, best practices, and future trends.

3. The Importance of IAM in Cloud Computing Definition: IAM manages digital identities, authenticates users, and enforces access controls in virtual infrastructures. Significance: Controls access to resources. Simplifies user management. Enhances security posture.

4. Challenges of Current IAM Implementation Complexity: Managing IAM across multiple platforms is challenging. Security Risks: Misconfigurations and weak authentication mechanisms pose risks. Compliance Requirements: Compliance with regulatory standards necessitates robust IAM controls. User Experience: Balancing security with user convenience is crucial.

5. Cross Chain for Multi Cloud IAM

6. Cross Chain for Multi Cloud IAM (2) Definition: Manages access to resources spanning multiple blockchain networks. Aspects: Identity Verification Permission Management Interoperability Standards Smart Contract Integration Privacy Preservation

7. Advantages of Cross-Chain IAM over Traditional IAM Scope: Controls access across multiple blockchain networks. Decentralization: Eliminates central authorities, enhancing security. Interoperability: Enables interoperability between diverse systems. Trust Model: Uses blockchain tech for trustless access control. Privacy and Security: Prioritizes privacy and security with cryptographic techniques. Resilience: Distributes policies across multiple networks, ensuring operational continuity.

8. Context Aware Dynamic Access Control Overview: Dynamic access control adapts access decisions in real-time based on various factors such as user attributes, environmental conditions, and system states. Significance: Unlike traditional access control mechanisms, dynamic access control ensures adaptive and context-aware access permissions.

9. Components: D2

10. Key Aspects of Dynamic Access Control Contextual Authorization: Factors considered: user identity, device attributes, location, time of access, and security posture. Example: Access decisions based on user roles, location, or data sensitivity. Attribute-Based Access Control (ABAC): Attributes: Users, resources, and environmental conditions. Dynamic access decisions based on attribute evaluation. Policy Evaluation Engine: Responsible for processing access control policies and making real-time access decisions. Adaptive Access Policies: Adjust access permissions based on changing conditions and risk levels. Example: Additional authentication requirements based on location or device security.

11. Evaluation User Credential visibility: D2 scheme ensures that the identity records of our users are securely stored in the cloud and blockchain. Access Policy storage as JSON: D2 use a JSON file for access policies where each document represents a user's policy. All documents are encrypted using public key encryption and the encryption key is secured in the configuration file. Accountability: D2 system records all activity in the blockchain, ensuring data and service integrity. SSO authentication status, authorization enforcement, and access control are tamper-proof. Token Reply attacks: To prevent token replay attacks, the ACSG stores user and session IDs for each token. SSL-secured connections encrypt all system parameters and protect against Man-in-the-Middle attacks.

12. Conclusion IAM is increasingly crucial: Challenges such as complexity, security risks, compliance requirements, and user experience issues exist for IAM in cloud environments, benefits of IAM outweigh the costs, emphasizing its importance. Emerging technologies: C ross-chain access control Dynamic Access Control IAM solutions must adapt to evolving cloud technologies to address new challenges and opportunities effectively.
