Custom OS Image Development

Custom OS Image Development

Build lightweight, secure operating system images from scratch for VMs, containers, and edge devices with full compliance documentation

Purpose-Built Operating Systems for Secure Deployments

We create minimal, hardened OS images tailored to your specific application requirements — reducing attack surface, improving performance, and ensuring compliance with China's cybersecurity regulations.

Minimal Attack Surface

Remove unnecessary packages and services to reduce vulnerabilities and improve security posture.

Security Hardening

Implement mandatory access controls, secure boot, and other hardening measures from the ground up.

Optimized Performance

Tailor the OS to your hardware and workload for maximum efficiency and responsiveness.

Our Custom OS Development Process

Building secure, efficient operating systems from the ground up

From Requirements to Build

We start with a thorough analysis of your application requirements, security needs, and compliance obligations to design an OS that meets your exact specifications.

Application-specific optimization
Minimal package selection
Performance profiling
Resource optimization

Security Hardening & Compliance

Every custom OS image is built with security as a priority, incorporating industry best practices and meeting China's cybersecurity requirements.

Mandatory Access Control (SELinux/AppArmor)
Secure boot configuration
Audit logging and monitoring
Compliance documentation for audits

Deployment & Integration

We deliver your custom OS images in the format that works best for your environment, with comprehensive documentation and support.

VM images (OVA, QCOW2, VHD)
Container base images
PXE bootable images
Embedded/edge device images

How We Build Custom OS Images

A systematic approach to creating secure, efficient operating systems

1

Requirements Analysis

We analyze your application, security, and compliance requirements to determine the optimal OS configuration.

2

Architecture Design

We design the OS structure, package selection, and security controls based on your requirements.

3

Image Building

We build the OS from scratch using automated tools, ensuring consistency and reproducibility.

4

Security Hardening

We implement security controls including MAC, secure boot, and audit logging.

5

Testing & Validation

We thoroughly test the OS for functionality, performance, and security vulnerabilities.

6

Documentation & Delivery

We provide comprehensive documentation and deliver the OS in your preferred format.

Real-World Application

Client Challenge

A medical device manufacturer needed a secure, lightweight operating system for their diagnostic equipment that would meet both medical device regulations and China's cybersecurity requirements. The standard OS images were too large and had unnecessary services that created security risks.

Our Solution

We built a custom Linux-based OS image from scratch, removing all unnecessary packages and services. We implemented mandatory access controls, secure boot, and comprehensive audit logging. The final image was 85% smaller than the standard distribution and met all regulatory requirements.

Results Achieved

85% reduction in OS image size
Successfully passed medical device and cybersecurity audits
Reduced boot time from 45 seconds to 8 seconds
Eliminated 95% of potential attack surface

"The custom OS image Corestack developed was perfect for our medical devices. It's secure, fast, and compliant with all the regulations we face. They understood both the technical and regulatory challenges we were dealing with."
— CTO, Medical Technology Company
