# Example command for setting up Nextcloud on Ubuntu
sudo snap install nextcloud

Auditable Codebases

Projects that allow developers to audit the codebase ensure transparency, making it harder for vulnerabilities to go unnoticed. Regular audits and community engagement can enhance security. For instance, a developer can run automated tests to check for vulnerabilities, incorporating tools like npm audit or pip-audit to ensure dependencies remain secure.

When developers actively participate in the auditing process, they can discover hidden vulnerabilities before they are exploited. For example, a recent audit of a popular open source framework revealed several outdated libraries that could potentially be exploited. The community swiftly patched these vulnerabilities, ensuring the framework remained secure for users.

# Example command for auditing npm packages
npm audit

Commercial Open Source

Using commercial open source solutions can give you the best of both worlds: the freedom of open source and the security of professional support. For example, Red Hat offers a subscription model that includes support and services for enterprise applications. This can be a game-changer for businesses looking to balance cost and security.

By choosing a commercial open source solution, businesses gain access to dedicated support teams that can help resolve security issues swiftly. This level of support can be crucial during security incidents, where every second counts. In fact, organizations leveraging commercial support often experience faster response times to security threats, reducing potential damage.

Community-Driven Solutions

Community-driven solutions are fundamental in maintaining the security of open source projects. Engaging with communities can help identify vulnerabilities faster. For instance, participating in community forums, contributing to documentation, or even code submissions can make a significant impact on a project’s security posture.

Many successful projects have implemented regular security sprints, where contributors focus solely on security improvements. These events not only address existing vulnerabilities but also foster a culture of security within the community. For example, during a recent security sprint for a popular CMS, contributors identified and resolved over 50 vulnerabilities in just a few days.

Case Study: A Real-World Example

Let’s look at an actual case involving a self-hosted system. A small startup decided to implement Nextcloud as their file-sharing solution. They faced several internal security issues with their previous open source solution, which was too exposed to potential exploits.

After transitioning, they could customize their environment. They set up stringent access controls and regular audits of their data usage. This shift resulted in a 60% decrease in security incidents within six months.
