Cloud Computing — Security in Cloud Computing

Security is a top concern in cloud computing. Cloud providers implement various measures to protect data and applications:

  • Encryption: Data is encrypted both while stored and in transit.
  • Firewalls: Protect systems from unauthorized access.
  • Identity and Access Management (IAM): Controls who can access which resources.
  • Multi-Factor Authentication (MFA): Adds an extra layer of security for logins.
  • Regular Backups: Prevent data loss during system failures or cyberattacks.

While providers handle much of the security, customers also share responsibility by properly configuring their cloud environments (known as the Shared Responsibility Model).

Example: AWS provides IAM to manage access permissions, but the customer must correctly set policies to prevent accidental data leaks.
