nw-security-and-governance SKILL.md skillA
nw-security-and-governance from nwave-ai/nwave is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nwave-ai/nwave/nw-security-and-governance@git:20260320.d98f3cbPins git:20260320.d98f3cb in mdr.lock. Pin the fingerprint instead.

Database security (encryption, access control, injection prevention), data governance (lineage, quality, MDM), and compliance frameworks (GDPR, CCPA, HIPAA).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Security and Governance
## Defense-in-Depth Security Model
Layered security, each layer provides independent protection:
1. **Encryption at rest** (TDE) — protects against physical media theft
2. **Encryption in transit** (TLS/SSL) — protects against network interception
3. **Access control** (RBAC/ABAC) — enforces least privilege
4. **SQL injection prevention** — protects against application-layer attacks
5. **Audit logging** — accountability and forensic capability
## Encryption at Rest (TDE)
Encrypts DB files on disk without application changes. Encrypts data pages before writing, decrypts on read into memory. AES 128/256-bit symmetric encryption. Transparent to applications.
### Key Hierarchy (SQL Server)
1. Service Master Key (Windows DPAPI) -> 2. Database Master Key -> 3. Certificate -> 4. Database Encryption Key (DEK)
### Implementation
```sql
-- SQL Server TDE (key hierarchy: Service Master Key -> DB Master Key -> Certificate -> DEK)
CREATE DATABASE ENCRYPTION KEY WITH ALGORITHM = AES_256
ENCRYPTION BY SERVER CERTIFICATE TDE_Cert;
ALTER DATABASE [YourDB] SET ENCRYPTION ON;

How to install
mdr add nwave-ai/nwave/nw-security-and-governance@sha256:f14bdaaec185bca9The line at the top of this page pins the label git:20260320.d98f3cb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
