SC-27 Platform-independent Applications
High-Level Description
Family: System and Communications Protection (SC)
Framework: NIST SP 800-53 Rev 5
Platforms are combinations of hardware, firmware, and software components used to execute software applications. Platforms include operating systems, the underlying computer architectures, or both. Platform-independent applications are applications with the capability to execute on multiple platforms. Such applications promote portability and reconstitution on different platforms. Application portability and the ability to reconstitute on different platforms increase the availability of mission-essential functions within organizations in situations where systems with specific operating systems are under attack.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for SC-27 implementation details. Verify the organization has documented how this control is satisfied.
Step 2: Validate Implementation
# For cloud environments, use cloud-audit-mcp tools
# For on-premises, review system configurations directly
# Example: Check if account management policies exist
grep -r "account.management\|access.control" /etc/security/ 2>/dev/null
Step 3: Test Operating Effectiveness
Verify the control is actively functioning, not just documented. Check logs, configurations, and operational evidence.
Tools

| cloud-audit-mcp | Check encryption and network controls | cloud_audit_encryption |
| nmap | Network scanning | nmap -sV --script ssl-enum-ciphers |

Implementation Guidance
Platforms are combinations of hardware, firmware, and software components used to execute software applications. Platforms include operating systems, the underlying computer architectures, or both. Platform-independent applications are applications with the capability to execute on multiple platforms. Such applications promote portability and reconstitution on different platforms. Application portability and the ability to reconstitute on different platforms increase the availability of mission-essential functions within organizations in situations where systems with specific operating systems are under attack.
