What is Patch Management
Patch management is a process that proactively identifies, tests, and installs software patches to fix security vulnerabilities or bugs in computer systems and applications.
It is a critical part of any organization’s security and risk management strategy and is often handled by a dedicated IT security team.
Patch management is essential because it helps protect a company’s networks, systems, and applications from security threats and malicious attacks.
Importance of Patch Management
Here are some reasons why software patching is one of the most important exercises for IT teams.
First, patch management helps ensure that all devices in the network have the latest security patches. This prevents any breaches when an intruder identifies a vulnerability.
Second, patch management can help reduce the risk of system failures and downtime since it allows you to quickly and easily install the latest patches and updates. This can help improve the overall reliability and stability of your network.
Finally, patch management can save time and resources since it automates managing and deploying patches and updates, allowing you to focus on other important tasks.
Effective patch management can help a company improve its security, performance, and compliance, leading to increased profits. For example, suppose a company can avoid a costly security breach or legal penalty. In that case, it can save significant amounts of money to be reinvested in the business to drive growth and profitability.
Types of Patches
Here are some of the types of patches that may be used in patch management
Security patches
Such patches address vulnerabilities in software or hardware that attackers could exploit to gain unauthorized access or cause damage.
Performance improvements
Certain patches optimize software or hardware performance by increasing speed or reducing resource usage.
Emergency patches
Address urgent issues or vulnerabilities that require immediate attention. Such as critical security vulnerabilities or critical bugs.
Bug fixes
They address issues or errors in software or hardware that may cause problems or disrupt regular operation.
Feature updates
These patches add new features and capabilities to software or hardware and directly impact the operations.
Steps involved in Patch Management
In a large enterprise, patch management typically involves the following steps
Identifying Patches
This typically involves determining which systems and software need to be updated and determining which patches are relevant for them.
Patch Testing
Before applying patches to production systems, it is important to test them in a test environment to ensure they do not cause any issues.
Patch Scheduling
Once the patches have been tested and approved, a schedule for installing them on production systems needs to be created. This may involve creating deployment policies.
Applying Patches
The patches are then applied to the production systems according to the schedule. This may involve gradually rolling them out to all the systems.
Monitoring Patch Installations
After the patches have been applied, the systems and software should be monitored to ensure that the patches have been applied correctly and that there are no issues.
Use Cases for a Patch Management
Patch management software ensures that your systems and applications are up-to-date.
Applying Security Patches
A patch management software can help you identify and apply security patches to your systems and applications to fix vulnerabilities.
Updating Software
A patch management software can help keep your software up to date by alerting you to new updates and providing an easy installation.
Fixing bugs
A patch management software can help you identify and fix bugs in your software by providing access to patches that fix known issues.
Adding New Features
A patch management software can help you add new features to your software by providing access to patches that add new functionality.
Choosing the Right Software
Factors to consider when choosing the right patch management software for a company
Compatibility
Ensure the software is compatible with your organization’s operating systems, hardware, and applications.
Ease of Use
Look for easy and understandable software, especially if it will be used by non-technical staff.
Automation
Consider whether the software offers automatic patch deployment and testing, as this can save time.
Scalability
Choose software that can handle the number of devices and systems in your organization.
Security
Look for software that offers robust security features, such as the ability to roll back patches if necessary.
Cost
Consider the cost of the software, including any ongoing maintenance fees and the cost of training.
Automating Patch Management with Motadata ServiceOps Patch Manager
Motadata offers a robust patch management solution designed to help organizations automate the process of managing the life cycle of patches. It does this through a centralized patch management repository, which retrieves all available patches from third-party repositories and distributes them across devices in the network.
How ServiceOps Patch Manager Works?
Vulnerability details are collected periodically from third-party software vendors and are put in the Central Patch Repository.
Devices with the agent application are scanned to identify the missing patches. In large, distributed networks, relay servers are also used to keep the ServiceOps main server updated.
All available patches are shown on the dashboard with proper labels, showing whether they are critical, security/non-security updates, service packs, rollups feature packs, etc.
All patches go through an approval process before they are pushed for deployment.
Users can create policies to control the deployment behavior, which includes scheduling options. Once a deployment is done, the same is updated in the ServiceOps main server.
ServiceOps Patch Manager Features
Automate the process of identifying and installing patches
Endpoint Scanning
Devices with the agent application are periodically scanned and synced with the main server.
Testing & Approval
Approve patches after testing them in a controlled environment and auto-approve them.
Reporting
Generate OOB reports or build your own, using custom conditions, to highlight the details of the deployments.
Decline Patches
Prevent problematic patches from deployment across devices or on certain devices, and prevent unwanted disruptions.
Patch Rollback
Remotely trigger uninstallation of patches for some devices or all devices at scale and achieve better control.
System Health
Find devices that are missing critical patches and generate reports.
Cross Platform Patching
Support for patches of both Windows and Linux operating systems.
Remote Configuration Setup
Remotely manage the configuration of devices through the registry values.
