Q1Domain Verified
In the context of Terraform security and IaC penetration testing, what is the primary risk associated with overly permissive IAM roles created through Terraform, and how would a specialist identify and mitigate this?
where applicable. C) The primary risk is denial-of-service (DoS) attacks on Terraform state files. Mitigation involves encrypting the Terraform state file using KMS.
The primary risk is drift between the declared infrastructure and the actual infrastructure. Mitigation involves using Terraform's `refresh` command regularly.
The primary risk is unauthorized access to sensitive data or resources due to the broad permissions granted. A specialist would identify this through static analysis of Terraform code for overly broad `*` or `Allow: *` statements and mitigate by implementing least privilege principles and using attribute-based access control (ABA
The primary risk is excessive resource provisioning, leading to increased cloud costs. Mitigation involves implementing resource quotas within Terraform modules.
Q2Domain Verified
During a penetration test of a Terraform-managed Kubernetes cluster, what is a common, yet often overlooked, vulnerability related to the `kubernetes_namespace` resource, and what is the most effective remediation strategy?
The vulnerability is the insecure storage of etcd credentials within the namespace. Remediation involves encrypting etcd data at rest.
The vulnerability is the lack of proper RBAC roles assigned to the namespace. Remediation involves creating specific `kubernetes_role` and `kubernetes_role_binding` resources for each namespace.
The vulnerability is the potential for resource exhaustion within a namespace due to lack of resource limits. The most effective remediation is to define `resource_quotas` and `limit_ranges` within the Kubernetes manifest applied by Terraform.
The vulnerability is the creation of public-facing namespaces. Remediation involves configuring network policies to restrict ingress and egress traffic.
Q3Domain Verified
A Terraform penetration tester discovers a Terraform configuration that provisions an S3 bucket with `acl = "public-read"`. Beyond the immediate data leakage, what is a sophisticated, secondary attack vector that an attacker could exploit in this scenario, and what Terraform-level control would be most effective in preventing it?
The secondary attack vector is manipulating the bucket's versioning settings to overwrite or delete critical data. Prevention involves disabling versioning for the S3 bucket.
The secondary attack vector is using the public bucket as a pivot point for distributed denial-of-service (DDoS) attacks by hosting malicious content. Prevention involves implementing S3 bucket policies that restrict access to specific IP ranges.
The secondary attack vector is exploiting cross-origin resource sharing (CORS) misconfigurations to access data from other domains. Prevention involves disabling CORS for the S3 bucket.
The secondary attack vector is using the public bucket to host phishing pages or malware, thereby impersonating legitimate services and tricking users into revealing credentials or downloading malicious software. The most effective Terraform-level control is to explicitly configure `acl = "private"` or `acl = "authenticated-read"` and enforce bucket policies that deny public read access, along with enabling `block_public_acls` and `block_public_policy` within the `aws_s3_bucket_public_access_block` resource.
