CAS-005 Exam Dumps : CompTIA SecurityX Certification Exam

The strings utility extracts human-readable text from binary files. Security analysts use it to identify Indicators of Compromise (IoCs) such as URLs, IP addresses, filenames, and commands embedded in the malware.

Option A (reconstructing timeline) would require event logs or forensic timeline tools.

Option C (replicating the attack) involves execution in a sandbox, not static string extraction.

The best approach is to use Terraform scripts while creating golden images (A). Terraform is an Infrastructure as Code (IaC) tool that allows organizations to automate infrastructure deployment consistently across environments. A golden image is a pre-configured, patched, and hardened system image used as a standard baseline. By creating golden images via Terraform scripts, the company ensures that every microservice instance is deployed on an already-updated and secure OS. This eliminates the need for repeatedly patching the base OS before code deployment.

Option B (cron job with apt-update) applies patches but introduces delays (every 30 days) and lacks consistency across new deployments. Option C (snapshots) saves deployment states but risks replicating outdated or unpatched images. Option D (centralized update server) is useful but still requires updates post-deployment, which slows the rollout of microservices.

By automating golden image creation through Terraform, the company gains efficiency, repeatability, and security assurance, aligning with DevSecOps principles and CAS-005 cloud-native best practices.

The best way to address these requirements is to apply Role-Based Access Controls (RBAC) combined with geolocation policies. RBAC ensures that customers are authenticated and authorized to access only the data they are entitled to, thereby minimizing data exposure risks. At the same time, geolocation policies enforce restrictions on which regions customers can access data from, helping with compliance requirements such as GDPR or regional sovereignty laws.

Option B (replicating data in each customer environment) is inefficient, expensive, and introduces additional risks related to data sprawl. Option C (regional hosting with unique links) complicates access management and does not inherently prevent exposure or enforce strong authentication. Option D (restricting to a single region provider) removes flexibility and may conflict with customer needs for global access.

Therefore, implementing RBAC along with geolocation controls provides fine-grained access management, ensures compliance, prevents unnecessary data exposure, and is scalable for a global cloud environment.
