# SA-15(8) Reuse of Threat and Vulnerability Information

> **Enhancement of:** SA-15

## High-Level Description

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

Analysis of vulnerabilities found in similar software applications can inform potential design and implementation issues for systems under development. Similar systems or system components may exist within developer organizations. Vulnerability information is available from a variety of public and private sector sources, including the NIST National Vulnerability Database.

## What to Check

- [ ] Verify SA-15(8) Reuse of Threat and Vulnerability Information is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for SA-15(8)
- [ ] Verify enhancement builds upon base control SA-15

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SA-15(8) 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

Require the developer of the system, system component, or system service to use threat modeling and vulnerability analyses from similar systems, components, or services to inform the current development process.

### Implementation Guidance

Analysis of vulnerabilities found in similar software applications can inform potential design and implementation issues for systems under development. Similar systems or system components may exist within developer organizations. Vulnerability information is available from a variety of public and private sector sources, including the NIST National Vulnerability Database.
