CompTIA SecurityX (CAS-005)Security ArchitectureMedium

A company is migrating its on-premises data center to a hybrid cloud environment. The security architect needs to ensure consistent security policies and visibility across both on-premises and cloud resources. Which of the following approaches BEST addresses this requirement?

  1. AEstablishing a dedicated VPN tunnel between the on-premises network and the cloud provider.
  2. BImplementing separate security tools and policies for each environment and manually syncing them.
  3. CDeploying a cloud access security broker (CASB) to enforce policies for SaaS applications.
  4. DUtilizing a unified security management platform that integrates with both on-premises and cloud APIs.
Show answer & explanation

Correct answer: D. Utilizing a unified security management platform that integrates with both on-premises and cloud APIs.

A unified security management platform provides a single pane of glass to define, deploy, and monitor security policies across diverse environments, including on-premises and multiple cloud providers. This ensures consistency and simplifies management, which is critical in a hybrid cloud scenario.

Why the other options are wrong

  • A. A VPN tunnel provides secure connectivity but does not inherently offer consistent security policy management or unified visibility across the connected environments.
  • B. Manually syncing separate tools and policies is prone to error, inconsistency, and is not scalable for a complex hybrid environment.
  • C. A CASB is primarily focused on SaaS application security and data governance, not comprehensive policy enforcement and visibility across IaaS/PaaS and on-premises infrastructure.

Unified Security Management (USM)

A comprehensive approach to security that integrates multiple security functions, tools, and processes into a single platform for centralized management and visibility across diverse IT environments.

  • Provides a single pane of glass for security operations.
  • Enables consistent policy enforcement across hybrid environments.
  • Integrates with various security tools and platforms.
  • Improves visibility and simplifies compliance reporting.
