An organization is migrating its core business applications to a multi-cloud environment, utilizing services from three different cloud providers. Each provider has its own unique security controls, APIs, and compliance certifications. The CISO needs to ensure consistent information security governance across this complex landscape. Which of the following approaches is MOST effective for establishing unified security governance in this multi-cloud context?
- AStandardize on the security controls offered by the most secure cloud provider and mandate their use across all other providers.
- BEngage a single third-party managed security service provider (MSSP) to assume full security responsibility for all cloud environments.
- CDevelop a common, cloud-agnostic security policy framework and implement automated tools for continuous compliance monitoring across all cloud platforms.
- DDelegate security governance responsibility to each individual cloud provider for their respective environments.
Show answer & explanationAnswer & explanation
Correct answer: C. Develop a common, cloud-agnostic security policy framework and implement automated tools for continuous compliance monitoring across all cloud platforms.
In a multi-cloud environment, delegating security or standardizing on one provider's controls is insufficient. A common, cloud-agnostic policy framework provides the unified governance, while automated tools are crucial for effectively and consistently monitoring compliance across disparate platforms. This approach ensures consistency and manageability.
Why the other options are wrong
- A. Standardizing on one provider's controls is often impossible due to differing capabilities and may not meet requirements of other providers.
- B. While an MSSP can assist, outsourcing full responsibility without an internal governance framework can lead to loss of control and accountability.
- D. Delegating governance to providers fragments control and prevents unified security posture.
Multi-Cloud Security Governance
The establishment and enforcement of consistent information security policies, controls, and processes across diverse and multiple cloud service providers used by an organization.
- Addresses disparate APIs, controls, and compliance.
- Requires a cloud-agnostic policy framework.
- Relies on automation for consistency and scalability.
