Overview
Cloud security refers to policies, technologies, and controls that protect data, applications, and infrastructure in cloud environments. Shared responsibility between cloud providers and users is critical.
Common Threats
- Data breaches due to misconfigured cloud storage.
- Denial of Service (DoS) attacks targeting cloud services.
- Insider threats abusing cloud privileges.
- Weak API security exposing data.
Real-World Example
In 2019, Capital One suffered a breach due to a misconfigured AWS S3 bucket, exposing sensitive financial data of over 100 million customers.
Best Practices
- Use strong Identity and Access Management (IAM) controls.
- Encrypt data at rest and in transit.
- Perform regular security audits and compliance checks.
- Monitor cloud environments with SIEM tools.
