Manual patching refers to the process of applying software updates, fixes, or patches manually rather than through automated systems. It usually involves downloading the patch or update, applying it to the system or software, and verifying that it works as intended.
This method is often used when automated patching tools are unavailable, or when the process requires careful control, such as in environments with strict security requirements or complex systems that need custom solutions. Manual patching can be time-consuming and prone to human error, but it allows for a more tailored and cautious approach to applying updates.
Automated Patching.
Automated patching is the process of applying software updates, fixes, or patches automatically through the use of tools or systems, without requiring direct human intervention for each update. These tools can schedule, download, install, and sometimes even test patches on software, operating systems, or applications.
Automated patching is typically used in environments that need to apply security updates quickly and consistently across multiple devices or systems. It reduces the risk of human error, saves time, and ensures that systems are up-to-date with the latest security and performance improvements. However, it may also introduce risks if patches are not tested thoroughly before deployment, potentially leading to compatibility issues or unintended consequences.
Tools.
There are several tools available for automated patching, depending on the type of systems, applications, or infrastructure you are working with. Here are some widely used tools for automated patching:
For Operating Systems
1. **WSUS (Windows Server Update Services)** – A Microsoft tool for automating patch management in Windows environments.
2. **SCCM (System Center Configuration Manager)** – Microsoft's enterprise-grade tool for patching Windows operating systems and applications.
3. **Linux Package Managers (e.g., APT, YUM, DNF)** – For Linux systems, tools like `apt` (Debian/Ubuntu), `yum` (CentOS/RHEL), and `dnf` (Fedora) can be used for automated OS patching.
4. **Red Hat Satellite** – Manages and automates patching for Red Hat Enterprise Linux (RHEL) systems.
5. **Canonical Landscape** – A tool for managing and automating updates for Ubuntu systems.
Cross-Platform Patch Management Tools
1. **Ivanti Patch Management (formerly Shavlik)** – Supports patching for both Windows and Linux systems, as well as third-party applications.
2. **ManageEngine Patch Manager Plus** – A comprehensive patch management tool that supports Windows, macOS, and Linux environments.
3. **SolarWinds Patch Manager** – Provides automated patching for both Microsoft and third-party applications.
4. **GFI LanGuard** – Offers automated patch management for Windows, macOS, and Linux systems.
5. **Kaseya VSA** – A unified tool for patch management, software deployment, and system monitoring across platforms.
Cloud-based and Hybrid Systems
1. **AWS Systems Manager Patch Manager** – For automating patch management on AWS EC2 instances and hybrid environments.
2. **Microsoft Azure Automation Update Management** – Automates patching for virtual machines in Azure or on-premises systems.
3. **Google Cloud OS Patch Management** – Automates patching for virtual machines in Google Cloud.
Third-Party Application Patching
1. **PDQ Deploy** – Automates patching for a wide range of third-party applications on Windows systems.
2. **Patch My PC** – Offers automated patching for third-party applications integrated with SCCM and Intune.
3. **Ninite Pro** – A tool for automated patching of common third-party Windows applications.
For Containers and DevOps Environments
1. **Chef Automate** – Provides patch management for systems through automated infrastructure management.
2. **Ansible** – An open-source automation tool that can handle patch management via playbooks.
3. **Puppet** – Automates the deployment and patching of applications and operating systems across multiple environments.
These tools simplify the process of keeping systems up to date and secure by automatically identifying and applying the necessary patches.
