Part 1: Executive Summary & Introduction

Executive Summary

In today’s world, schools and small-to-medium businesses (SMEs) rely heavily on digital tools and internet connectivity to operate smoothly. With this reliance comes the risk of cyberattacks and data theft. To protect sensitive information, many organizations must meet cybersecurity rules like the Cybersecurity Maturity Model Certification (CMMC) Level 1. This certification is especially important when working with U.S. government contracts.

This paper explains how open-source network management tools—namely Nagios and OpenNMS—can help schools and SMEs protect their networks and meet CMMC Level 1 requirements. These tools are free or low-cost alternatives to expensive commercial products and offer strong monitoring and alerting features. We also show how partners KeenComputer.com and IAS-Research.com support organizations with expert deployment and ongoing help.

Introduction

Why Network Management Matters
A network connects all the devices in an organization — computers, printers, servers, and more — allowing them to communicate. Good network management means making sure these devices are always working, secure from attacks, and running efficiently.

For schools, network issues can disrupt online classes or access to learning resources. For SMEs, network problems can cause lost sales, unhappy customers, or data breaches that damage reputation and lead to fines.

What is CMMC Level 1?
CMMC Level 1 sets out basic cyber hygiene practices required to protect sensitive but unclassified federal contract information. It includes rules about who can access systems, how devices are protected, and how information is kept safe.

Challenges for Schools and SMEs
Many schools and SMEs have limited budgets and IT staff, making it hard to buy and maintain costly network management systems. Open-source tools like Nagios and OpenNMS provide affordable, flexible solutions that fit these needs.

Part 2: Understanding CMMC Level 1: Compliance Overview

What is CMMC Level 1?

CMMC (Cybersecurity Maturity Model Certification) is a cybersecurity framework developed by the U.S. Department of Defense. It has different levels (1 to 5), with Level 1 being the most basic.

Level 1 requires 17 cybersecurity controls grouped into areas such as:

• Access Control: Only authorized people can use or change your systems.
• Identification and Authentication: You must confirm who users and devices are before giving access.
• Media Protection: Protect physical and digital copies of information.
• Physical Protection: Keep your servers and devices physically safe.
• System and Communications Protection: Monitor and secure data as it moves over the network.
• System and Information Integrity: Detect and fix software or hardware problems quickly.

Why is CMMC Important?

• It protects sensitive information from theft or damage.
• It's required for any organization doing business with the U.S. government.
• Helps improve overall cybersecurity, reducing risks of attacks.
