**Tenable, a leading force in vulnerability management, shares its best practices for establishing a robust cloud security program using their Tenable Cloud Security platform.**

**Tenable’s Infosec team has overcome numerous challenges in securing their cloud infrastructure. They’ve learned valuable lessons and implemented key best practices that they’re now sharing with other organizations.**

**The article highlights key steps for building a successful cloud security program:**

**1. Establishing Cloud Account Visibility and Ownership:**
– Gaining complete visibility into all cloud accounts, including production, development, and sandbox environments, is crucial.
– Determining resource usage and identifying potential overprivileged or publicly accessible resources is essential.
– Account owners should be assigned to each account, serving as primary contacts and decision-makers for security and risk acceptance.
– Multiple account owners are recommended for redundancy and smoother decision-making.

**2. Defining Roles and Permissions:**
– Clearly define teams that access each account and the level of access they require.
– Assign roles based on team responsibilities:
– **Collaborator:** For primary teams managing policies and adding resource labels.
– **Viewer:** For secondary teams reviewing findings and managing resources.
– **Administrator:** For IT/Infosec teams onboarding accounts, configuring settings, and managing access.

**3. Ensuring Compliance and Standards:**
– Implement continuous monitoring against industry standards such as CIS Benchmarks, GDPR, and NIST CSF.
– Determine the resources and data requiring protection and configure compliance reporting for the relevant accounts.
– Utilize scheduled reports to automatically email CSV attachments with compliance scores to relevant teams.

**4. Prioritizing Remediation Efforts:**
– Prioritize remediation based on severity and resource ownership.
– Utilize tagging policies for consistent resource management and faster incident response times.
– Leverage Labels feature within Tenable Cloud Security for identifying resource owners without tagging support.
– Address findings based on a predefined order of priority.

**5. Managing Exceptions and Risk Acceptance:**
– Implement policies for temporary and permanent exceptions to address unaddressed security issues.
– Hold account owners responsible for excluded resources and the impact on overall compliance scores.
– Utilize Tenable Cloud Security’s options for managing exclusions based on patterns or individual resources.

**6. Monitoring Performance and Compliance Metrics:**
– Track Key Performance Indicators (KPIs) to measure compliance progress against chosen standards.
– Utilize the Dashboard and Compliance sections in Tenable Cloud Security to monitor KPI metrics and compliance score changes.

**7. Communication and Collaboration:**
– Regularly meet with account owners to discuss the cloud security program and their responsibilities.
– Communicate clearly about account management, compliance reporting, remediation procedures, exclusion process, and targeted KPIs.
– Create internal documentation for easy reference by current and future account owners.

**Tenable’s article emphasizes the importance of a proactive approach to cloud security, highlighting the need for ongoing vigilance and collaboration between security teams and account owners. By implementing these best practices, organizations can effectively secure their cloud environments and mitigate potential cyber risks.**
