Imagine an attacker gaining unauthorized access to your sensitive data or taking control of your cloud infrastructure.
Penetration testing is a crucial step in identifying and addressing these vulnerabilities before they can be exploited.
In this post, we’ll explore 20 critical checks for penetration testing AWS cloud systems, along with possible real-world examples of how each vulnerability can be exploited.
1. Misconfigured security groups: An attacker can exploit open ports and unnecessary access rules to gain unauthorized access to instances and data.
2. IAM policies and roles: Overly permissive policies can allow attackers to elevate privileges and access sensitive resources.
3. Unencrypted data at rest: Without encryption, attackers can access sensitive data if they gain access to storage services.
4. Unencrypted data in transit: Insecure communication channels can be intercepted, allowing attackers to access sensitive data.
5. EBS volume snapshots: Unencrypted snapshots can be copied and used to access data, even after deletion.
6. S3 bucket permissions: Publicly accessible buckets can be accessed by anyone, allowing unauthorized data access or manipulation.
7. CloudTrail and CloudWatch configurations: Insufficient logging and monitoring can hinder incident response and forensic analysis.
8. Instance metadata exposure: Attackers can use metadata to gain unauthorized access to instances and data.
9. Default security settings: Default settings can leave services vulnerable to known attacks.
10. Unused resources: Unneeded resources can provide additional attack surface and increase the risk of data exposure.
11. Multi-factor authentication (MFA): Without MFA, attackers can easily gain unauthorized access to user accounts.
12. Port scanning and vulnerability assessment: Attackers can use these techniques to identify and exploit weaknesses in your infrastructure.
13. Access keys and secret keys: Improperly managed keys can be stolen and used to access your AWS resources.
14. Use of outdated AMIs: Outdated AMIs can contain known vulnerabilities that can be exploited by attackers.
15. Insecure data deletion: Improper data deletion can lead to data recovery by attackers.
16. Use of insecure protocols: Insecure protocols can be intercepted, allowing attackers to access sensitive data.
17. Insufficient resource isolation: Shared resources can lead to unintended access and data exposure.
18. Use of VPC peering: Improperly configured VPC peering can allow unauthorized access to resources.
19. NAT instances and security groups: Incorrectly configured NAT instances and security groups can allow unauthorized access to instances and data.
20. Use of AWS services with known vulnerabilities: Attackers can exploit known vulnerabilities in AWS services to gain unauthorized access or disrupt services.
