security-hardening

SKILL.md

Proactive reduction of attack surface across infrastructure layers through systematic configuration hardening, least-privilege enforcement, and automated security controls. Applies industry-standard CIS Benchmarks and zero-trust principles to operating systems, containers, cloud configurations, networks, and databases.

Default Deny, Explicit Allow Start with all access denied, explicitly permit only required operations. Apply default-deny firewall rules and network policies, then allow specific traffic.

Least Privilege Access Grant minimum permissions required for operation. Use RBAC, IAM policies with specific resources, and database roles with limited permissions (no DELETE or DDL unless required).

使用 CIS 基准和零信任原则减少跨操作系统、容器、云、网络和数据库层的攻击面。在强化生产基础设施、满足合规性要求或实施深度防御安全时使用。 来源：ancoleman/ai-design-components。
