# IA-5(4) Automated Support for Password Strength Determination

> **Enhancement of:** IA-5

## High-Level Description

**Family:** Identification and Authentication (IA)
**Framework:** NIST SP 800-53 Rev 5

No description available.

## What to Check

- [ ] Verify IA-5(4) Automated Support for Password Strength Determination is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for IA-5(4)
- [ ] Verify enhancement builds upon base control IA-5

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for IA-5(4) 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                      |
| --------------- | ------------------------------ | -------------------------- |
| cloud-audit-mcp | Check authentication settings  | `cloud_audit_iam_policies` |
| hackbrowser | Test authentication mechanisms | `hackbrowser`        |

## Remediation Guide

### Control Statement

Refer to NIST SP 800-53 Rev 5 for the full control statement.

### Implementation Guidance

Implement this control per organizational risk assessment and system categorization.
