Best Practice: Implement cloud security controls like CASB, encryption, and IAM
Sep 12, 2024
With organisations increasingly relying on cloud services, robust cloud security measures are essential to protect data and applications. Solutions like Cloud Access Security Brokers (CASBs), Identity and Access Management (IAM), and encryption help secure your cloud environment, ensuring that your systems and data remain safe from breaches or unauthorised access.
Why Cloud Security Controls Matter
- Improved visibility: CASB solutions provide visibility into cloud activity, allowing organisations to detect and respond to potential security threats in real time. This ensures continuous monitoring of cloud environments, reducing the risk of data breaches.
- Controlled access: IAM tools allow organisations to control who can access specific cloud resources. By enforcing least-privilege principles, businesses can limit the risk of unauthorised access, ensuring that only the right people have access to sensitive data.
- Data protection: Encryption is essential for protecting sensitive data stored in the cloud. Even if data is intercepted or accessed by unauthorised users, encryption ensures it cannot be read without the correct decryption keys.
Implementing This Best Practice
- Use a CASB solution: Implement a Cloud Access Security Broker (CASB) like Netskope or McAfee MVISION to monitor cloud activity and enforce security policies. CASBs help ensure compliance, secure sensitive data, and prevent unauthorised access to cloud services.
- Enforce IAM policies: Use Identity and Access Management (IAM) tools to create and manage access controls for your cloud environment. Implement least-privilege policies to limit users’ access to only the resources they need.
- Apply encryption: Ensure that all sensitive data in your cloud environment is encrypted, both at rest and in transit. Cloud providers such as AWS, Azure, and GCP offer encryption services to help organisations secure their data across different environments.
Conclusion
Implementing robust cloud security controls is crucial for protecting your organisation’s data and applications in the cloud. By using CASB solutions, enforcing IAM policies, and applying encryption across all cloud environments, you can mitigate security risks and ensure your cloud infrastructure remains secure and compliant with industry standards.
