# SC-42(4) Notice of Collection

> **Enhancement of:** SC-42

## High-Level Description

**Family:** System and Communications Protection (SC)
**Framework:** NIST SP 800-53 Rev 5

Awareness that organizational sensors are collecting data enables individuals to more effectively engage in managing their privacy. Measures can include conventional written notices and sensor configurations that make individuals directly or indirectly aware through other devices that the sensor is collecting information. The usability and efficacy of the notice are important considerations.

## What to Check

- [ ] Verify SC-42(4) Notice of Collection is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for SC-42(4)
- [ ] Verify enhancement builds upon base control SC-42

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SC-42(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 encryption and network controls | `cloud_audit_encryption`             |
| nmap            | Network scanning                      | `nmap -sV --script ssl-enum-ciphers` |

## Remediation Guide

### Control Statement

Employ the following measures to facilitate an individual’s awareness that personally identifiable information is being collected by [organization-defined]: [organization-defined].

### Implementation Guidance

Awareness that organizational sensors are collecting data enables individuals to more effectively engage in managing their privacy. Measures can include conventional written notices and sensor configurations that make individuals directly or indirectly aware through other devices that the sensor is collecting information. The usability and efficacy of the notice are important considerations.
