AI Governance Frameworks
AI governance is the regulatory frame around technical safety. Major frameworks NIST AI RMF — voluntary US framework; maps risks across lifecycle EU AI Act — risk-tiered (banned, high-risk, limited-risk, minimal); 2024 effective UK pro-innovation — sector-by-sector approach China — algorithm filing, content moderation requirements India — DPDP applies to AI processing PII; specific AI […]
Production AI Deployment Patterns
Production AI is engineering. Choices have security and cost implications. Hosting choices Pattern Privacy Cost Quality OpenAI / Anthropic / Google managed Lowest (data leaves) Pay-per-token; scales Highest Azure OpenAI Moderate (Microsoft tenant; opt-out training) Same as OpenAI Same AWS Bedrock Moderate (your AWS account) Higher Same Self-hosted (Llama, Qwen, Mistral) Highest GPU-rental; ops effort […]
RAG Security
RAG combines vector search + LLM. Security model is hybrid. Threats specific to RAG Vector store data exposure — anyone with access reads embeddings (and retrieves originals) Indirect prompt injection via retrieved docs — adversary plants malicious doc; RAG retrieves and follows instructions IAM bypass via vector similarity — user query semantically matches private docs […]
Azure Incident Response
Module 7 (Blue Team) covered IR generally. This is the Azure-specific actions. Compromised account playbook Disable user account in Entra ID Revoke active sessions and refresh tokens (Revoke-AzureADUserAllRefreshToken) Reset password Review AD audit logs for the user (last 30 days) Check for created service principals or app registrations Review M365 mailbox forwarding rules Review consent […]
GCP Organisation Hierarchy
GCP’s hierarchy is the foundation of multi-project security. Levels Organisation — top; tied to your Google Workspace / Cloud Identity domain Folders — group projects (by environment, business unit) Projects — workload boundary; resources live here Resources — buckets, instances, etc. IAM inheritance Roles granted at higher levels apply to all child resources. Org-level Owner […]
VPC Service Controls
VPC Service Controls = GCP’s data-exfiltration defence. Define a perimeter; data can’t leave it even with valid credentials. The model Perimeter wraps GCP services + projects Inside perimeter: free communication Outside attempting to access services inside: blocked unless explicit ingress rule Inside attempting to send to outside: blocked unless explicit egress rule Common patterns Lock […]
Azure RBAC Mastery
Module 9 (Cloud track) covered privesc paths. This module is the operational guide. Scope hierarchy Management Group → Subscription → Resource Group → Resource. Inheritance flows down. Least-privilege principle: assign at the lowest scope possible. Built-in roles to know Owner — full control + can manage access Contributor — full control without manage-access Reader — […]
BigQuery Security
BigQuery is the most-used data warehouse for Indian fintech. Security model is rich; most teams use 30%. Access patterns Dataset-level — coarse; user can see entire dataset or none Authorized views — view exposes subset to other users without granting access to underlying tables Row-level security — policies restrict which rows a user sees Column-level […]
Google Secret Manager
GCP’s native secrets store. Simpler than Vault; sufficient for most. Features Versioned secrets (latest, specific version) IAM-scoped access Replication policies (auto / user-managed) Cloud KMS encryption Audit log per access Secret Manager Notifications for rotation triggers Pattern gcloud secrets create my-secret --replication-policy=automatic gcloud secrets versions add my-secret --data-file=./secret.txt # In application from google.cloud import secretmanager […]
Cloud Armor for WAF & DDoS
Cloud Armor = Google’s edge security. WAF + DDoS + bot mitigation. Layers Standard — basic L3/4 DDoS, included with HTTP(S) load balancer Plus — adaptive DDoS protection, ML-based, paid tier WAF rules — preconfigured (OWASP CRS) + custom Bot management — reCAPTCHA Enterprise integration Common WAF rules OWASP CRS (XSS, SQLi, RCE, LFI/RFI) Custom […]
