Patch Management and Software Deployment
Product: NEXTMEGABYTE (Greenitco ITAM) · Module: Patch Management (ITOM) · Audience: Administrator
Patch management is the systematic process of identifying, acquiring, testing, deploying and verifying software updates (patches) across operating systems, applications and firmware. Software deployment delivers, installs or removes applications on endpoints.
- Deployment makes software available to users.
- Patch management keeps that software secure and up to date.
Together they improve the performance, security and reliability of your endpoints. Both are part of the IT Operations Management (ITOM) capabilities of NEXTMEGABYTE.
A patch is a set of code changes from a software vendor that fixes security vulnerabilities, resolves bugs, improves performance or stability, or adds features and compliance updates.
The patch management agent is a lightweight client installed on each endpoint (workstation, server or laptop). It communicates with the portal to automate the full patching lifecycle.
Why use patch management
| Reason | Benefit |
|---|---|
| Security | Unpatched systems are the most common entry point for cyberattacks and ransomware |
| Compliance | Helps meet standards such as ISO 27001, HIPAA, PCI-DSS and GDPR |
| Bug fixes | Removes defects that cause crashes and data loss |
| Performance | Optimization patches improve speed and reliability |
| Consistency | All devices run approved, uniform software versions |
| Visibility | Full insight into patch status on every endpoint |
| Automation | Replaces manual, error-prone patching across hundreds of machines |
| Business continuity | Less downtime from security incidents and software failures |
Patch categories
| Category | Fixes or adds | Examples |
|---|---|---|
| Security patches | Known vulnerabilities | Windows security update, OpenSSL fix |
| Bug fixes | Functional defects | Application crash fix, memory leak patch |
| Feature updates | New or improved features | New UI components, API enhancements |
| Service packs | Cumulative bundles of fixes | Windows SP1, quarterly vendor update |
| Driver updates | Hardware drivers | GPU, network card and printer drivers |
| Firmware updates | Low-level device firmware | BIOS/UEFI update, SSD firmware |
| Third-party app patches | Non-OS software | Chrome, Adobe, Java, Zoom |
| OS updates | Core operating system | Windows Update, kernel patch |
Patch sync
When an administrator triggers Sync, the system:
- Connects to vendor patch sources (Microsoft WSUS, third-party feeds and CVE databases).
- Downloads the latest patch metadata: ID, name, severity, category, release date and affected versions.
- Compares it with the software installed on each endpoint.
- Calculates the compliance gap (patches available but not installed).
- Updates the dashboard with the latest patch inventory and compliance status.
