How to Meet the CMMC 2.0 Incident Response Requirement: Best Practices for CMMC Compliance

The Cybersecurity Maturity Model Certification (CMMC) 2.0 is a critical benchmark for defense contractors in the Department of Defense’s (DoD) supply chain, otherwise known as the defense industrial base (DIB). CMMC seeks to protect sensitive information, specifically controlled unclassified information (CIA) and federal contract information (FCI).

An essential component of CMMC compliance is the implementation of a robust incident response plan This requirement not only enhances an organization’s ability to respond to and recover from cyber incidents but also strengthens its overall security posture.

In this blog post, we will explore this critical requirement, including basic principles and best practices for creating and implementing an effective incident response plan for CMMC compliance that obviously has broader benefits than just compliance.

The CMMC certification process is arduous but our CMMC 2.0 compliance roadmap can help.

CMMC 2.0 Overview

The Cybersecurity Maturity Model Certification (CMMC) 2.0 is the Department of Defense’s (DoD) comprehensive framework designed to safeguard the defense industrial base from increasing cybersecurity threats. CMMC 2.0, like its predecessor CMMC 1.0, aims to ensure that defense contractors implement mandatory cybersecurity standards to securely handle Controlled Unclassified Information (CUI) and Federal Contract Information (FCI). Significant changes from CMMC 1.0 to CMMC 2.0 include streamlining the model into three levels, CMMC Level 1 (Foundational), CMMC Level 2 (Advanced), and CMMC Level 3 (Expert), and better alignment with NIST standards like NIST 800-171 and, to a lesser extent, NIST 800-172. CMMC 2.0’s maturity levels essentially scale cybersecurity practices according to the sensitivity of the data handled. Consequently, assessments that evaluate CMMC compliance span from self-assessment for CMMC Level 1 to assessment by a certified third-party assessor organization (C3PAO) for CMMC Level 2 and CMMC Level 3 (in some cases).

CMMC 2.0 consists of 14 domains, each covering various aspects of cybersecurity. These domains are Access Control (AC), Audit and Accountability (AA), Awareness and Training (AT), Configuration Management (CM), Identification and Authentication (IA), Incident Response (IR), Maintenance (MA), Media Protection (MP), Personnel Security (PS), Physical Protection (PP), Risk Management (RM), Security Assessment (CA), System and Communications Protection (SC), and System and Information Integrity (SI). Each domain contributes to an overarching goal of securing critical information. We will focus the remainder of this post on the Incident Response requirement.
