# SA-3(3) Technology Refresh

> **Enhancement of:** SA-3

## High-Level Description

**Family:** System and Services Acquisition (SA)
**Framework:** NIST SP 800-53 Rev 5

Technology refresh planning may encompass hardware, software, firmware, processes, personnel skill sets, suppliers, service providers, and facilities. The use of obsolete or nearing obsolete technology may increase the security and privacy risks associated with unsupported components, counterfeit or repurposed components, components unable to implement security or privacy requirements, slow or inoperable components, components from untrusted sources, inadvertent personnel error, or increased complexity. Technology refreshes typically occur during the operations and maintenance stage of the system development life cycle.

## What to Check

- [ ] Verify SA-3(3) Technology Refresh is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for SA-3(3)
- [ ] Verify enhancement builds upon base control SA-3

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SA-3(3) 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

| Tool          | Purpose                           | Usage |
| ------------- | --------------------------------- | ----- |
| Manual Review | Documentation and interview-based | N/A   |

## Remediation Guide

### Control Statement

Plan for and implement a technology refresh schedule for the system throughout the system development life cycle.

### Implementation Guidance

Technology refresh planning may encompass hardware, software, firmware, processes, personnel skill sets, suppliers, service providers, and facilities. The use of obsolete or nearing obsolete technology may increase the security and privacy risks associated with unsupported components, counterfeit or repurposed components, components unable to implement security or privacy requirements, slow or inoperable components, components from untrusted sources, inadvertent personnel error, or increased complexity. Technology refreshes typically occur during the operations and maintenance stage of the system development life cycle.

## Risk Assessment

| Finding                                    | Severity | Impact                                     |
| ------------------------------------------ | -------- | ------------------------------------------ |
| SA-3(3) Technology Refresh not implemented | Medium   | System and Services Acquisition            |
| SA-3(3) partially implemented              | Low      | Incomplete System and Services Acquisition |
