Cloud Data Security

1. Moving to the Cloud: Convenience comes with Risks

Using cloud services like Google Workspace, Microsoft 365, AWS, or Azure brings amazing flexibility. However, without proper security configurations, businesses face serious threats:

• Employees accidentally sharing important data files outside the company (Public sharing).
• Admin accounts stolen due to lack of MFA, leading to complete system takeover.
• Source code leaks, misconfigured AWS S3 buckets exposing customer information.

2. Multi-Layer Cloud Security Architecture

Cyber IT Security provides comprehensive security solutions for Cloud environments following the Shared Responsibility model:

Component	Purpose
Access Control (IAM)	Strictly manage who is allowed to access which resource, and from where (IP/Country).
MFA & SSO	Mandatory multi-factor authentication for all cloud accounts.
Data Loss Prevention (DLP)	Prevent sharing and sending of sensitive data (ID, Credit Cards, Contracts) externally.
CSPM (Cloud Security Posture Management)	Scan for misconfigurations on AWS/Azure/GCP, continuous vulnerability alerting.
Cloud Backup	Automated periodic backup for Office 365, G-Suite, preventing encryption or accidental deletion.

3. Services by Specific Platform

Google Workspace & Microsoft 365

Set up Context-Aware Access, Conditional Access. Configure MDM to manage mobile devices accessing company mail. Deploy advanced anti-Spam, Phishing, and Malware rules.

AWS / Azure Infrastructure

Configure Network Security Groups, VPCs, WAF. Deploy CloudTrail, GuardDuty to monitor abnormal behaviors. Periodic Well-Architected Framework reviews.

4. Deployment Process

1. Assessment: Scan the entire current Cloud system, identifying misconfigurations and vulnerabilities.
2. Design: Create a security plan tailored to the workflow.
3. Deployment: Enable MFA, configure DLP policies, monitor access.
4. Training & Handover: Guide users and internal IT staff on secure system management.
