Security configuration management (SCM) is essential for the success of an organization’s overall security posture. This integral function of a holistic cybersecurity program targets the configurations of elements in the IT environment such as operating systems, applications, network devices, cloud assets, databases, servers, directory services, POS terminals, and workstations. Configuration security is important because misconfigurations continue to prove popular attack vectors for cybercriminals attempting to access private systems and data.
What Is Security Configuration Management?
SCM is a central process in cybersecurity where configuration settings across a digital environment are assessed, corrected when necessary, and regularly monitored for changes that could result in a security breach or non-compliance with regulatory standards. The National Institute of Standards and Technology (NIST) defines security configuration management as “The management and control of configurations for an information system to enable security and facilitate the management of risk.”
Large organizations with complex digital environments have thousands of configurations to manage. This process is inordinately time-consuming (if not altogether impossible) if done manually, so many organizations rely on automated SCM solutions that scan for misconfigurations. The more closely configurations are monitored, the quicker security teams can act to block their associated attack vectors.
Organizations that only monitor configurations intermittently are more likely to experience configuration drift, wherein configurations deviate over time without the organization's awareness — allowing misconfigurations to linger undetected.

How Does Security Configuration Management Work?
What is the security configuration management process? Like most of the key processes of cybersecurity, SCM isn’t a one-step operation, but rather a continual effort including discovery, baselining, change detection, and remediation.
Asset Discovery
The first step of SCM is to ensure that all assets and their current configurations are accounted for in a centralized repository. These assets must also be categorized and tagged appropriately to ensure effective configuration management. Automated SCM solutions that scan continuously can identify new assets as soon as they appear.
Configuration Baselining
Misconfigurations can only be found and fixed when there is a secure baseline with which to compare them. Determining the correct configuration for each asset may seem daunting, but best practice frameworks like the Center for Internet Security (CIS) and NIST provide prescriptive configuration benchmarks to follow.
Change Detection
After all assets are detected, categorized, and have their baselines established, it’s time to determine how frequently to run a configuration policy assessment. SCM solutions allow you to set assessment schedules and view the resulting data. For example, a centralized dashboard can provide instant visibility into the amount and severity of misconfigurations throughout the organization.
Remediation
The final component of the continuous process of SCM is remediation of unauthorized, unsecure, or non-compliance changes. Strong SCM solutions will provide clear, detailed remediation guidance to enable security teams to quickly return configurations back to their secure baseline states. Effective SCM solutions also do the heavy lifting in terms of prioritizing misconfigurations based on their associated risks.

The Importance of Security Configuration Management
Misconfigurations are one of the most popular attack vectors for threat actors. Most default configuration settings are designed for ease of use, not security, so it’s vital to have solutions in place to detect and correct configurations that leave systems exposed.
