Summary of “Week 2 Lab: Identity and Security Services in Cloud”

This video explains the concepts and practical aspects of identity and security services in cloud computing, focusing on the differences between AWS and Azure platforms. The main ideas are illustrated through an analogy with database management systems (DBMS) and access control, then extended to cloud identity and access management.

Main Ideas and Concepts

1. Recap of Week 1

• Account creation in cloud platforms.
• Exploration of regions, zones, and services.

2. Analogy with Database Management Systems (DBMS)

• Databases contain multiple tables with varying sensitivity of data.
• Example:
  • Table 1 holds sensitive info (usernames, passwords).
  • Table 2 holds customer info.
  • Table 3 holds original complaint data.
• Access to tables is controlled by the Database Administrator (DBA).
• Different users (junior developers, team leads, project managers) have different access permissions.
• Roles and groups are created to manage access efficiently.
  • Example groups:
    • Development group: access to tables T2, T3, T7.
    • Testing group: access to tables T2, T3, T8, T9.
• Purpose: Prevent accidental data loss or unauthorized data access by restricting permissions.

3. Identity and Security Services in Cloud Platforms

• Similar access control concepts are implemented in cloud platforms but with platform-specific services.

AWS: Identity and Access Management (IAM)

• After account creation and login, permissions to access services and resources (e.g., S3 buckets) are managed via IAM.
• Example: Role 1 uploads a file to an S3 bucket; whether Role 5 can access it depends on IAM permissions.
• Permissions can be set to public, private, or restricted to specific roles/users.
• IAM controls access after login.

Azure: Azure Active Directory (Azure AD)

• Security restrictions are applied before login during account creation and login.
• User selects a role (developer, admin, user) during login.
• Based on the role, the user can only see and access certain services.
• Access is role-based and enforced at login time, so no manual permission setting is needed after login.

4. Key Differences Between AWS IAM and Azure AD

• AWS allows anyone to create an account and login, but access to resources is controlled after login through IAM policies.
• Azure restricts access by role selection during login, controlling what services the user can see and use upfront.
• AWS permissions are granular and resource-specific (e.g., individual files in S3 buckets).
• Azure permissions are broader, role-based, and set at the directory/admin level.

5. Practical Instructions for Week 2 Lab

• AWS users:
  • Explore IAM service.
  • Create an S3 bucket.
  • Upload sample data (e.g., answer sheets).
  • Practice assigning permissions to control who can access the data.
• Azure users:
  • Experiment with creating accounts with different roles (developer, admin, user).
  • Observe what services each role can access post-login.
• Document findings and understand the differences in identity and security management between AWS and Azure.

6. Learning Recommendations

• Use internet resources and AI tools (like GPT) to research IAM and Azure AD.
• Understand the purpose and implementation of identity and access management in cloud environments.
• Prepare for future labs and projects by mastering these concepts.

Methodology / Instructions for the Lab

For AWS

• Login to AWS account.
• Navigate to IAM service.
• Create an S3 bucket (e.g., “bucket_mca”).
• Upload files (e.g., answer sheets).
• Set permissions on the bucket or files:
  • Make files public or private.
  • Assign access to specific roles/users.
• Verify access by logging in as different roles/users.

For Azure

• Create accounts with different roles (developer, admin, user).
• Login using each role.
• Observe and note the services accessible to each role.
• Understand how access is restricted before login based on role selection.

General

• Record observations.
• Compare and contrast AWS IAM and Azure AD approaches.
• Use external resources for deeper understanding.
