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 基準和零信任原則減少跨操作系統、容器、雲、網絡和數據庫層的攻擊面。在強化生產基礎設施、滿足合規性要求或實施深度防禦安全時使用。 來源：ancoleman/ai-design-components。
