SCCM Patch Management

System Center Configuration Manager (SCCM) is a comprehensive systems management tool provided by Microsoft that enables IT administrators to automate the deployment, management, and monitoring of software across a network. One of its primary features is patch management, which allows organizations to deploy critical updates, security patches, and software fixes efficiently.

SCCM patch management can be used to deploy updates to a variety of devices, including:

  • Windows computers
  • Windows servers
  • Mac computers
  • Linux computers
  • Mobile devices

How the SCCM tool works

1. Infrastructure Setup

To deploy SCCM, you need to set up the required infrastructure. This typically includes installing the SCCM server on a dedicated machine and configuring the necessary components such as the site database, management point, distribution point, software update point, and reporting services point. These components work together to facilitate the management and distribution of software and updates.

2. Discovery and Inventory

SCCM performs discovery to identify and gather information about devices on the network. Discovery methods include Active Directory system discovery, network discovery, and user discovery. Once discovered, SCCM collects inventory data from the devices, capturing hardware and software details, installed applications, and other relevant information.

3. Software Deployment

SCCM enables administrators to deploy software packages, applications, and updates to client devices. Administrators can create deployment packages containing the necessary files and instructions for software installation. These packages can be customized based on requirements, such as specifying installation behavior, and dependencies, and targeting specific devices or user collections. Deployment methods include mandatory, available, and user-initiated deployments.

4. Patch Management

SCCM offers robust patch management capabilities. It integrates with Windows Server Update Services (WSUS) to synchronize with Microsoft Update servers and obtain the latest software updates, security patches, and hotfixes. The SCCM software update point (SUP) downloads and stores these updates in the SCCM database. Administrators can then create software update groups, which contain a collection of updates to be deployed. SCCM provides deployment rings and maintenance windows to control the deployment process, allowing updates to be tested in controlled environments before wider deployment.

5. Client Communication and Policy Enforcement

SCCM relies on client agents installed on managed devices to communicate with the SCCM server and receive instructions. These agents communicate through various channels, including the management point, distribution point, and software update point. SCCM applies policies to client devices to enforce configurations, software installations, updates, and other management tasks. Clients regularly check in with the SCCM server to receive policy updates and report their status.

6. Reporting and Monitoring

SCCM provides extensive reporting capabilities to monitor and track the status of managed devices, deployments, compliance, and other key metrics. Administrators can access built-in reports or create custom reports based on specific requirements. The reporting services point component in SCCM enables the generation and distribution of reports to stakeholders within the organization.

7. Endpoint Protection

SCCM integrates with Windows Defender Antivirus, allowing administrators to manage antivirus settings, monitor protection status, and deploy antivirus definitions to client devices. This integration enhances endpoint security by ensuring that antivirus software is up to date on all managed devices.

8. Updates and Upgrades

Microsoft regularly releases updates and upgrades to SCCM itself. These updates provide bug fixes, security patches, and new features. SCCM administrators can use the SCCM console to check for and apply these updates to their SCCM infrastructure, ensuring the tool is up-to-date and operating efficiently.

Features of SCCM Patch Management

  • Software Update Point (SUP): SCCM uses a SUP role to synchronize with Microsoft Update servers and obtain the latest software updates and patches. The SUP also provides an updated catalog that allows administrators to review and select updates for deployment.
  • Deployment Packages: SCCM organizes updates into deployment packages, which can be customized based on criteria such as update type, language, and platform. These packages are then distributed to distribution points for deployment to client devices.
  • Maintenance Windows: SCCM allows administrators to define maintenance windows during which patching activities can occur. This helps minimize disruptions by ensuring updates are installed at suitable times.
  • Baselines and Compliance Settings: SCCM supports the creation of software update baselines and compliance settings to enforce the installation of critical updates and maintain a secure environment.
  • Reporting and Monitoring: SCCM provides comprehensive reporting capabilities, including dashboards and detailed reports, to track the progress and success of patch deployments, identify issues, and ensure compliance.
