Implementing a customized security framework tailored to your infrastructure and risk tolerance allows you to tap the speed and efficiency of the cloud while defending against its new threats.

In this comprehensive guide, we‘ll cover:

  • Key drivers prompting companies like yours to adopt frameworks
  • Common components that make up frameworks
  • Pros and cons of leading industry frameworks
  • Steps to customize a framework for your needs
  • Expert guidance on maximizing frameworks

Let‘s get you up to speed on protecting your cloud environments!

Why Companies Are Adopting Cloud Security Frameworks

First, what exactly is a cloud security framework?

It‘s a set of documented policies, controls, procedures and best practices organized to protect data, apps and infrastructure hosted in public clouds, private clouds or SaaS services.

Frameworks provide pre-defined controls to safeguard cloud deployments that organizations cancustomize to their needs.

By establishing a standardized approach to cloud security aligned with industry standards, companies realize several advantages:

Tighter Security Posture

Certifications earned by implementing regulations like ISO 27001 validate you‘re meeting best practices for info security.

Streamlined Compliance

Maintaining controls that satisfy PCI DSS, HIPAA and other data regulations gets easier.

Improved Risk Management

Centralized visibility into cloud risks and risk metrics help you prioritize and justify security spending.

Business Enablement

Documented diligence around security reassures customers and leadership that data remains protected.

Let‘s explore why improving cloud security posture grows more urgent.

Threat Trends Driving Adoption of Frameworks

  • Over 30 billion records have been exposed in the cloud since 2013 according to RiskBased Security.
  • Thales reports 69% of companies have experienced a cloud data breach.
  • Gartner predicts that through 2025, 99% of cloud security failures will result from preventable misconfigurations or poor access policies.

As your company adopts cloud services like IaaS, PaaS and SaaS, you take on new responsibilities for securing these environments.

But multi-cloud complexity makes this difficult:

  • 82% of organizations have a multi-cloud strategy according to Flexera.
  • IDC predicts there will be 100 Zettabytes of data in the cloud by 2025.

Without clear ownership or uniform controls and visibility across all this cloud sprawl, gaps emerge that attackers aggressively exploit.

The escalating tempo of software releases also heightens risks:

  • Over 1 million new malware threats emerge every day on average as per AV-Test Institute.
  • Gartner anticipates dev teams will deploy software over 5 times faster thanks to agile and CI/CD tools by 2023, leaving security playing catch-up.

By defining policies, rules and controls specifically for cloud in a structured framework, you can equip stretched security teams to lock down cloud deployments and prove governance over distributed environments.

Elements of a Cloud Security Framework

While approaches vary, most cloud security frameworks incorporate elements like:

Policies and Standards

These provide baseline rules and expectations for security practices across your org.

Risk Assessments

Inventories of cloud assets paired with continuous evaluations of vulnerabilities and threats.

Access Controls

Managing identities and limiting data/resource access with checks like MFA and dynamic authorization.

Network Safeguards

Tools like cloud firewalls, intrusion detection systems and microsegmentation.

Data Security

Encrypting data at rest and in transit along with monitoring for unauthorized activities.

Audits and Monitoring

Tracking operational controls and risk metrics required to prove security and compliance.

Next let‘s survey some of the most widely adopted security frameworks you could leverage.

Performing an assessment of your existing security program maturity and deficiencies when measured against a framework can help determine which is the best fit for your cloud objectives.

Selecting an Optimal Framework

Factors to consider when selecting a framework include:

Industry

If regulations like HIPAA or PCI DSS apply to your company, prioritize frameworks that incorporate related controls.

Existing Controls

No need to reinvent the wheel. Lean towards frameworks resembling security efforts you already have in place.

Business Requirements

Consider frameworks mandated by partners you exchange data with or providers you rely on.

Internal Resources

The overhead tied to certifications like ISO 27001 must be accounted for.

Cloud Models

Assess if guidance adequately covers your specific deployment models like IaaS, PaaS or SaaS.

Once selected, frameworks require further customization. Let‘s examine this process next.

Tailoring Frameworks to Your Needs

Rather than forcefitting an rigid one-size-fits all framework, savvy security teams morph industry standards to their organization‘s requirements. You‘ll need to:

Establish Ownership

Appoint resources to steward framework implementation and ensure stakeholder alignment on direction.

Perform Assessments

Map your infrastructure, data flows, workloads and code pipelines before analyzing risks.

Delegate Control Responsibilities

Determine the split of security duties between your company and any cloud providers based on service models.

Identify Gaps

Pinpoint areas where existing program deviates from framework guidance.

Define a Transition Roadmap

Create a priority-based rollout plan listing controls to deploy, adjust or strengthen over time.

Integrate with Operations

Embed security deeper into processes like CI/CD and procurement to increase adoption.

Leverage Automation

Reduce reliance on manual reviews by codifying policy enforcement and responses using infrastructure as code tools.

Keep Current

Revisit and update the tailored framework periodically to address new threats.

Now let‘s explore some real-world examples of security frameworks deployed by prominent companies.

Frequently Asked Questions

Do frameworks guarantee you‘ll avoid cloud breaches?

Unfortunately no. Frameworks outline areas requiring safeguards but don‘t flag specific holes. Ongoing auditing and scanning for misconfigurations or vulnerabilities remains essential.

We already conform with HIPAA and PCI DSS. Why adopt another framework?

While stringent, these standards don‘t encompass all possible cloud risks. More holistic frameworks will strengthen defenses based on learnings beyond your industry.

Isn‘t requiring cloud providers to have ISO 27001 certification sufficient?

While certification indicates robust security foundations are in place, you still need internal policies and controls tailored to your deployment models and data flows.

Our org accumulates tons of cloud security posture data. How can we leverage it?

Centralizing then correlating posture metrics using a data lake approach allows you to uncover trends, find coverage gaps and improve risk quantification efforts.

How much organizational change is involved in adopting frameworks?

Obtaining stakeholder input upfront helps smooth adoption. But depending on current maturity, the roadmap may necessitate new budget, tools, skill sets, processes and executive reporting.

What are examples of "as code" safeguards we can leverage?

Policy as code solutions let you programmatically define then enforce policies for resources provisioning, configuration standards, anomaly response and access permissions.

Should every company adopt the same foundational framework?

Not necessarily. Optimization involves balancing industry drivers, geographic regulations, existing processes and architectural constraints unique to your business.
