Wazuh: Building robust cybersecurity architecture with open source tools. Cybersecurity architecture refers to the design and structure of an organization's approach to securing its information systems. It outlines the components, policies, technologies, and processes to protect digital assets. The primary objective of a cybersecurity architecture is to establish a robust, resilient, and well-integrated defense against a wide range of cyber threats. Building a cybersecurity architecture requires organizations to leverage several security tools to provide multi-layer security in an ever-changing threat landscape. However, the cost required to implement these security solutions could be enormous for small and medium enterprises (SMEs). Leveraging open source tools and solutions to build a cybersecurity architecture offers organizations several advantages, such as cost-effectiveness, flexibility, community support, and transparency. Open source solutions allow organizations to customize and adapt their cybersecurity infrastructure to specific needs while benefiting from the collective expertise of the global open source community. Security design implementation Safeguarding an organization's digital assets requires the implementation of policies, processes, controls, and technology, with technology playing a vital role. Some key areas to consider when implementing a security architecture include: Organizations require various security tools that satisfy the key areas of a security architecture as they each play a role in securing digital assets. For example, an anti-virus solution for endpoint security, web application firewall for application security, network firewall for network security, and SIEM solution for monitoring and compliance. Leveraging open source tools in cybersecurity Open Source Software (OSS) is software that is distributed with its source code available for use and modification while retaining its original rights. It is shared openly, enabling anyone to access the repository for independent code use or to contribute to the project's design and functionality. OSS is often designed with interoperability in mind. It promotes the sharing of improvements and innovations within the community of developers, contributors, and users who collaborate to improve the software. This approach leads to rapid development, bug fixes, and enhancements of OSS. There are many open source security projects on the internet. Leveraging these open source projects can help organizations reduce the cost of implementing security solutions as it eliminates paying licensing fees associated with proprietary solutions. This cost savings can be significant for organizations, especially those with budget constraints. Some open source security tools and their functions Building a cybersecurity architecture using open source software requires a strategic approach to selecting security tools that align with the roles and requirements of each component within the security framework. Below are examples of some open source tools that can fulfill these roles in a cybersecurity architecture. Taking it a step further with Wazuh Wazuh is a security solution that offers unified SIEM and XDR protection across several platforms.
