Data Security Policy

Our Commitment to Your Privacy

BizCloud Experts does NOT share, sell, rent, or distribute your data to any third parties. Your data remains strictly confidential and is used solely for the purpose of delivering our AWS cloud services to you. We implement industry-leading security measures to protect your information at all times.

Overview

This Data Protection & Security Policy defines best practices to safeguard data for applications hosted on AWS under AWS Managed Services (AMS). It outlines essential controls across classification, encryption, access management, monitoring, backup, and incident response to maintain confidentiality, integrity, and availability of information.

Purpose

The purpose of this policy is to provide clear and actionable guidelines for protecting organizational data on AWS. It aims to ensure consistent implementation of security measures, support compliance with regulatory requirements, and minimize risk of data breaches or loss.

Audience

This policy is intended for use by the in-house cloud operations, security, and development teams responsible for deploying and managing applications on AWS.

Data Classification

• Classify all data by sensitivity (Public, Internal, Confidential, Regulated).

• Tag AWS resources accordingly (e.g.

  Classification=Confidential

  ) and enforce via guardrails.

Encryption

• At Rest: Mandate KMS-encrypted storage (S3, EBS, RDS) using customer-managed CMKs.

• In Transit: Require TLS for all service endpoints and inter-service traffic.

• In Use: Employ Nitro Enclaves or equivalent for sensitive in-memory processing.

Access Control

• Enforce least-privilege IAM policies scoped to specific ARNs and actions.

• Leverage tag-based (ABAC) policies to align permissions with resource classification.

• Apply restrictive resource policies (S3 bucket, KMS key policies) tied to approved principals and network sources.

Key Management

• Maintain separate CMKs per environment (Dev, Prod) and per data domain.

• Enable automatic CMK rotation; audit all key usage via CloudTrail.

• For FIPS-140-2 L3 requirements, utilize AWS CloudHSM or custom key stores.

Monitoring & Logging

• Activate CloudTrail, VPC Flow Logs, S3 access logs, and KMS key usage logs.

• Continuously assess compliance with AWS Config rules and AWS Security Hub.

• Deploy threat detection services (GuardDuty, S3 Access Analyzer).

Backup & Recovery

• Centralize and automate backups using AWS Backup.

• Implement cross-Region replication (S3) and multi-AZ configurations (RDS/EBS).

• Conduct regular recovery drills to validate RTO/RPO objectives.

Data Lifecycle Management

• Define retention periods per classification; automate lifecycle rules (e.g., S3 expiration, snapshot pruning).

• Enforce secure deletion processes in accordance with retention policies.

Incident Response

• Maintain runbooks for data-related incidents (unauthorized access, key compromise).

• Automate rapid containment via EventBridge-triggered Lambda actions (e.g., isolate instances, revoke keys).

• Track and remediate findings through AWS Config auto-remediation and Security Hub.

Governance & Review

• Enforce policy guardrails for tagging, encryption, IAM via AMS.

• Perform periodic audits and policy reviews to address new compliance requirements and emerging threats.

• Update best practices as AWS services evolve and threat landscapes change.
