The Cyber Resilience Act (CRA) is a European Union regulation aimed at improving the cybersecurity of products and services. One of its key concepts is the “minimal attack surface.”

A minimal attack surface refers to the reduction of opportunities for malicious actors to exploit vulnerabilities in a product or system. In simpler terms, it’s about limiting the number of ways a cyberattack can be launched successfully.

Key aspects of achieving a minimal attack surface include:

• Limiting Functionality: Reducing unnecessary features or components that could introduce vulnerabilities.
• Secure Design: Ensuring that the product or system is designed with security in mind from the outset.
• Regular Updates: Providing timely security patches and updates to address known vulnerabilities.
• Secure Configuration: Configuring the product or system to minimize risks and vulnerabilities.
• Third-Party Risk Management: Assessing and mitigating risks associated with third-party components or services.

By adhering to these principles, organizations can significantly reduce their exposure to cyber threats and enhance their overall cybersecurity posture.
