Final answer:
Good practices in attack surface reduction include eliminating system complexity, scanning and fixing vulnerabilities, implementing a DMZ network, and establishing Zero-trust policies. These strategies are focused on minimizing potential entry points for attackers and enhancing an organization's security posture.
Step-by-step explanation:
To answer your question about good practices in attack surface reduction, we can look at several strategies.
- Eliminate system complexity by simplifying the number of systems in use and reducing the number of features and components that can be attacked.
- Scan and fix vulnerabilities regularly to keep systems secure from known risks.
- Implement a DMZ network (Demilitarized Zone) which is a physical or logical subnetwork that contains and exposes an organization's external-facing services to a larger, untrusted network, usually the internet.
- Implement Zero-trust policies which assume no user or system is trusted by default, requiring verification at every step.
Each of these practices contributes to a robust security posture by minimizing potential entry points for attackers.
