Simulate Basic Cloud Attacks and Apply Defensive Measures

Welcome!

You are a Junior Cloud Security Analyst at CyberSecure Solutions. The organization wants to test whether its cloud environment is protected against common security threats.

Using an authorized training cloud environment, you will simulate basic attacks, identify the security weakness, apply defensive measures, and verify that the attack is no longer successful.

Topic : Cryptography and Cloud Security 

1) Cloud Architecture & Web Application Hosting

2) Access Control & Identity Exploitation

3) API Security in Cloud Environments Storage, Data Exposure & Misuse

4) Cloud Attack Simulation & Defense

Understand how incorrect permissions can allow unauthorized users to access cloud resources.

Create two test users:

Attempt to access the same resource

Give User A access to a test cloud resource

Log in as User B

Record whether access was allowed or denied

Observe the result

Expected Output :-

Understand the risk of giving users unnecessary permissions.

Select a test IAM user

Review the user's permissions

Identify unnecessary privileges

In the training environment, assign an intentionally excessive permission set

Log in as the test user

Verify what additional actions the user can perform

Record the security risk

Example :

Expected Output :-

Understand how incorrect cloud storage settings can expose sensitive data

Open the assigned test storage bucket/container

Place a dummy confidential file inside it

Enable public access according to the instructor's lab setup

Test whether the file can be accessed without authentication

Record the result

Do not use real personal or confidential information

Example :

Expected Output :-

Correct the identified security weaknesses.

For each simulated attack:

Disable unnecessary public access

Remove excessive permissions

Apply least privilege

Ensure only authorized users can access resources

Enable appropriate logging and monitoring

Save the configuration

Example :

Expected Output :-

Confirm that the defensive measures work.

Log in as the unauthorized test user

Attempt to access the protected resource

Attempt the previously excessive action

Try to access the protected storage object

Review the cloud logs

Confirm that unauthorized actions are denied

Example :

Record what happened before and after applying the security controls

For each vulnerability, record:

Example :-

• Vulnerability: Public Cloud Storage
• Severity: High
• Description:The storage resource allows unauthorized users to access stored objects.
• Impact: Sensitive company information may be accessed or downloaded.
• Recommendation: Disable unnecessary public access and apply least-privilege access controls.

Example :-

• Vulnerability: Public Cloud Storage
• Severity: High
• Description:The storage resource allows unauthorized users to access stored objects.
• Impact: Sensitive company information may be accessed or downloaded.
• Recommendation: Disable unnecessary public access and apply least-privilege access controls.

Great job!

You have successfully completed your first lab on Cloud Security Attack Simulation and Defense.

In this lab, you have: Simulated basic attacks in an authorized cloud environment, Identified security weaknesses, Applied appropriate defensive measures, and Verified that the implemented security controls prevented the attacks from succeeding.
