Best Practices for Cloud Security

  • As part of the “Best Practices” series by Uplatz

 

Welcome to the Uplatz Best Practices series — your trusted guide to building secure, scalable systems in the cloud.
 Today’s focus: Cloud Security — protecting your infrastructure, data, and workloads in an ever-evolving threat landscape.

🧱 What is Cloud Security?

Cloud Security refers to a set of policies, controls, technologies, and procedures that work together to protect cloud-based systems — including infrastructure, applications, and data — from cyber threats and misconfigurations.

Cloud security spans:

  • Identity & Access Management (IAM)

  • Data encryption

  • Network security

  • Compliance

  • Runtime monitoring and more

✅ Best Practices for Cloud Security

Cloud security is a shared responsibility — while cloud providers secure the platform, it’s up to you to secure your usage of it.

1. Apply Least Privilege Access (LPA)

🔐 Use IAM Roles and Policies, Not Root Accounts
 🚫 Grant Just Enough Access, Just In Time (JIT)
 🧭 Review and Rotate Access Keys Periodically

2. Encrypt Everything

🔒 Enable Encryption at Rest and In Transit
 🔐 Use KMS or HSM for Key Management
 📜 Define Key Rotation Policies and Monitor Usage

3. Use Multi-Factor Authentication (MFA) Everywhere

📱 Require MFA for All Admin and Console Access
 🔁 Enforce MFA via Identity Providers (Okta, Azure AD, etc.)
 🚫 Disallow Access Without Second-Factor Verification

4. Implement Strong Perimeter and Network Controls

🛡 Use Security Groups, NSGs, and Firewalls Strategically
 🌐 Isolate VPCs/Subnets by Environment or App Tier
 🔌 Limit Public Exposure — Use Bastion Hosts, NATs, and VPNs

5. Continuously Monitor and Audit

📈 Enable Cloud-Native Monitoring (e.g., AWS GuardDuty, Azure Defender)
 📋 Log All Activities via CloudTrail, CloudWatch, or GCP Audit Logs
 🔍 Set Alerts for Unusual Behavior and Anomalies

6. Implement Identity Federation and SSO

🧾 Centralize Identity Management Using SAML, OIDC, or LDAP
 🛑 Avoid Creating Long-Lived Local Users in Cloud Platforms
 🔄 Sync User Access with Enterprise Directories

7. Secure Containers and Serverless

📦 Scan Images and Functions for Vulnerabilities (e.g., Trivy, Snyk)
 🚫 Don’t Run Containers as Root
 📊 Monitor for Unexpected Runtime Behavior (e.g., Falco, AWS Lambda Guardrails)

8. Use Compliance Frameworks and Benchmarks

📚 Align with Standards like CIS, NIST, ISO 27001
 🧰 Use Tools Like AWS Config, Azure Policy, or GCP Organization Policy
 🛠 Automate Compliance Checks via Policy-as-Code

9. Backups and Recovery Are Non-Negotiable

📤 Back Up Data Regularly Using Managed Services (e.g., S3, Azure Backup)
 🔁 Test Recovery Scenarios Periodically
 🧪 Secure and Encrypt Backups Just Like Primary Data

10. Train Your Teams and Simulate Attacks

🎓 Conduct Regular Cloud Security Awareness Programs
 🎯 Run Red Team Exercises and Attack Simulations
 📘 Create Incident Response Playbooks

💡 Bonus Tip by Uplatz

Security isn’t a product. It’s a practice.
 In the cloud, everything is programmable — so should your security be.
 Automate, audit, and always assume breach.
