This article speaks to the benefits of automating vulnerability management This document provides self-assessment guidance for conducting Cybersecurity Maturity Model Certification (CMMC) assessments for Level 1. This article speaks to key components of a vulnerability management program for MSP's. In this blog, Kaseya will discuss patch management policy best practices and explain how they contribute to a better patching environment for large and small organizations alike. This guide is intended to provide small and medium-sized organizations with guidance for using Microsoft 365 (M365) to satisfy the Cybersecurity Maturity Model Certification (CMMC) Level 1 requirements. Microsoft Entra ID meets identity-related practice requirements in each Cybersecurity Maturity Model Certification (CMMC) level. To be compliant with requirements in CMMC, it's the responsibility of companies performing work with, and on behalf of, the US Dept. of Defense (DoD) to complete other configurations or processes. In CMMC Level 1, there are three domains that have one or more practices related to identity: Access Control (AC), Identification and Authentication (IA), and System and Information integrity (SI) This article explains the best ways to remediate vulnerabilities in a timely and prompt manner. This NIST Special Publication is designed to provide guidelines for BIOS protections in server-class systems. This NIST Special Publication is designed to provide a comprehensive set of security recommendations for the current landscape of the storage infrastructure. This NIST Special Publication is designed to assist organizations in understanding the basics of enterprise patch management technologies. This article from PurpleSec identifies the importance of prioritizing vulnerabilities. This article from Sprocket Security highlights the challenges of vulnerability management and how to establish an effective vulnerability management program.
Organizations identify systems that are affected by announced software and firmware flaws including potential vulnerabilities resulting from those flaws and report this information to designated personnel with information security responsibilities. Security-relevant updates include patches, service packs, hot fixes, and anti-virus signatures. Organizations address flaws discovered during security assessments, continuous monitoring, incident response activities, and system error handling. Organizations can take advantage of available resources such as the Common Weakness Enumeration (CWE) database or Common Vulnerabilities and Exposures (CVE) database in remediating flaws discovered in organizational systems.
Organization-defined time periods for updating security-relevant software and firmware may vary based on a variety of factors including the criticality of the update (i.e., severity of the vulnerability related to the discovered flaw). Some types of flaw remediation may require more testing than other types of remediation. NIST SP 800-40 provides guidance on patch management technologies.
Further Discussion
All software and firmware have potential flaws. Many vendors work to remedy those flaws by releasing vulnerability information and updates to their software and firmware. OSAs should have a process to review relevant vendor notifications and updates about problems or weaknesses. After reviewing the information, the OSA should implement a patch management process that allows for software and firmware flaws to be fixed without adversely affecting the system functionality. OSAs should define the time frames within which flaws are identified, reported, and corrected for all systems.
