System Hardening / Attack Surface Reduction
Limit the Exposure of Systems and Applications to Threats
System hardening involves implementing security measures to reduce a system's attack surface. By applying best practices from recognized standards, organizations can significantly reduce their attack surface and protect against potential threats.
This proactive approach includes removing unnecessary services and configuring systems according to established security guidelines and best practices. By doing so, your organization can ensure a strong baseline of security across its entire IT infrastructure.
System hardening is an ongoing process. To ensure that your systems remain resilient against attacks, regular reviews and updates are essential to maintain security as threats evolve and your infrastructure changes.
Frameworks for System Hardening
CIS Benchmarks are a set of best practice guidelines for securely configuring IT systems. Developed through a consensus process involving cybersecurity experts from around the world, these benchmarks provide prescriptive guidance for hardening systems against cyber threats. CIS Benchmarks cover a wide range of technologies, including operating systems, applications, cloud providers, network devices, and more.
The Defense Information Systems Agency (DISA) Security Technical Implementation Guides (STIGs) are a set of security protocols designed to safeguard U.S. Department of Defense (DoD) systems and networks from cybersecurity threats. These guidelines provide detailed configuration standards to ensure that systems are secure and compliant with DoD requirements. STIGs cover a wide range of technologies, including operating systems, applications, network devices, and more.
Key Differences
- Scope and Audience: DISA STIGs are specifically designed for DoD systems and contractors, while CIS Benchmarks are intended for a broader audience, including private sector organizations.
- Development Process: DISA STIGs are developed by the DoD, whereas CIS Benchmarks are created through a community-driven consensus process.
- Compliance Requirements: Compliance with DISA STIGs is mandatory for DoD entities, while CIS Benchmarks provide voluntary best practice guidelines.
