Cloud Security India — ISO 27001 and RBI Compliance 2026

Cloud Security India — ISO 27001 and RBI Compliance 2026

Moving to cloud does not automatically mean secure. Many Indian businesses migrate to AWS or Azure and then configure resources incorrectly — public S3 buckets, open security groups, shared access keys — creating significant security vulnerabilities. For regulated industries (NBFCs, healthcare, fintech), cloud security is also a regulatory requirement under RBI circulars, SEBI guidelines, and the DPDP Act 2023.

Cloud Security Threats for Indian Businesses

Misconfigured Resources
- Open S3 bucket: sensitive data publicly accessible
- Overly permissive IAM: one compromised credential = full account access
- Unpatched instances: old EC2 or Azure VMs with known vulnerabilities
- Default passwords: databases and admin panels with default credentials

Identity and Access Attacks
- Phishing: employee credential stolen, used to log into cloud console
- API key exposure: API keys committed to GitHub repository (publicly visible)
- Privilege escalation: attacker with limited access escalates to admin

Data Breaches
- Unencrypted databases: data readable by anyone with access to storage
- SQL injection: unprotected application allows database dump
- Insider threat: overprivileged employee or contractor accesses sensitive data

Regulatory Consequences
- DPDP Act breach notification: 72 hours to notify Data Protection Board
- RBI penalty: data breach at NBFC = regulatory action, possible COR cancellation
- Reputational damage: Indian businesses that suffer visible breaches lose clients

RBI Cloud Security Requirements for NBFCs

RBI's circular on outsourcing and cloud requires NBFCs to:
- Ensure data localisation: personal financial data stored in India
- Right to audit: NBFC (and RBI) can audit the cloud provider
- Incident reporting: security incidents reported to RBI within prescribed timelines
- BCP/DR: cloud deployment supports Business Continuity Planning
- Vendor risk management: cloud provider assessed as a service provider
- Data segregation: NBFC's data not commingled with other tenants

MICS Cloud Security Implementation

Identity and Access Management (IAM)
- IAM policy review: remove overly permissive policies
- Principle of least privilege: each user/service has minimum permissions needed
- MFA enforcement: multi-factor authentication for all console logins
- Role-based access: developers, operations, read-only — different permission sets
- Service accounts: API keys rotated, secrets stored in Secrets Manager / Key Vault
- Privileged Access Workstation: VPN required to access production environment

Network Security
- VPC/VNet design: application, data, and management tiers isolated
- Security groups/NSGs: tightest possible ingress rules — only required ports open
- WAF (Web Application Firewall): protect web applications from OWASP Top 10
- AWS Shield / Azure DDoS Protection: protect against DDoS attacks
- Private endpoints: databases accessible only from within private network, not internet
- Bastion host: no direct SSH/RDP from internet — all access via bastion

Data Encryption
- Encryption at rest: all storage (S3, EBS, RDS, Azure Blob) encrypted with AES-256
- Encryption in transit: TLS 1.3 for all data movement
- Key management: AWS KMS / Azure Key Vault for encryption key management
- Database encryption: RDS / Azure SQL transparent data encryption enabled

Monitoring and Detection (SIEM)
- AWS CloudTrail / Azure Activity Log: all API calls logged — who did what, when
- CloudWatch / Azure Monitor: resource metrics and custom alerts
- AWS GuardDuty / Microsoft Defender: AI-powered threat detection
- SIEM: centralised log aggregation (AWS Security Hub, Azure Sentinel)
- Alert: unusual login location, privilege escalation attempt, high API call rate

Vulnerability Management
- AWS Inspector / Microsoft Defender for Servers: OS and container vulnerability scanning
- Patch management: Systems Manager Patch Manager for automated patching
- Container scanning: Trivy or Grype on Docker images in CI/CD pipeline
- Penetration testing: annual VAPT of cloud infrastructure and applications

Backup and Recovery
- Automated backups: RDS automated backups, EBS snapshots on schedule
- Cross-region backup: production data backed up to a different region
- Backup testing: quarterly restore test — verify backups are usable
- RTO/RPO targets: defined and tested for each application

Compliance Reporting
- AWS Security Hub / Azure Policy: compliance score against frameworks (CIS, PCI DSS, ISO 27001)
- DPDP Act: data inventory, access logs, breach response procedure
- RBI compliance documentation: data localisation evidence, access controls, incident log
- Monthly security report: for CISO or board

#

ISO 27001 on Cloud

For Indian companies pursuing ISO 27001 certification:
- MICS aligns cloud security controls to ISO 27001 Annex A controls
- Evidence collection: access logs, change management, backup records — ready for auditor
- Gap assessment: current cloud security vs. ISO 27001 requirements
- Remediation: close gaps before formal certification audit
