Checklist: Security for your cloud infrastructure

Your cloud infrastructure can be made secure with a clear strategy and continuous measures. With our checklist, you can keep an eye on all important security aspects.

Secure access and authentication

• Implement strong password policies: Complex, unique passwords and regular updates are mandatory.
• Activate multi-factor authentication: This is an additional layer of protection that prevents unauthorized access even if passwords are stolen.
• Apply the zero trust principle: Every access is checked, regardless of whether it comes from the internal or external network.

Keep rights and authorizations to a minimum

• Implement the principle of least privilege: Each user only receives the access rights they need for their tasks.
• Perform regular authorization checks to quickly remove outdated or unnecessary access.
• Use time-limited access: Enable sensitive authorizations only for specific requirements.

Strengthen network and infrastructure protection

• Segment the network: Operate critical systems in separate zones to shorten attack paths.
• Use firewalls and intrusion detection systems to block unwanted traffic and detect suspicious activity.
• Use VPNs and secure protocols: Only allow data transfers via encrypted connections.

Back up and protect data

• Encryption at rest and in transit: Sensitive information should be encrypted at all times, and the keys must be managed securely.
• Secure key management should be implemented, for example through the use of hardware security modules or central KMS (Key Management Service).
• Regular backups and recovery tests should be carried out to ensure that data can be restored quickly in an emergency.

Ensuring monitoring and transparency

• A central log management system should be set up to collect all security-relevant events in one place.
• Use real-time monitoring to immediately recognize and react to conspicuous activities.
• Particularly privileged accounts should always be kept in view and administrator activities should be logged separately.

Promoting safety awareness in the team

• Regular training courses on phishing, social engineering and secure IT use raise employee awareness.
• Carry out realistic phishing tests to identify weaknesses in behavior and rectify them in a targeted manner.

Adhering to compliance and standards

• Identify relevant standards and regulations (e.g. GDPR, ISO 27001 or industry-specific requirements)
• Regularly check processes for conformity and compare safety guidelines with legal requirements.

Establish emergency management

• Create an incident response plan in which you define clear responsibilities, communication channels and instructions for action.
• Use early warning systems: Activate automatic notifications for suspicious events.
• Carry out emergency drills: Realistically simulate an emergency to test procedures.

Proactively eliminate weak points

• Perform regular security scans to detect vulnerabilities at an early stage.
• Penetration tests should be planned in order to check systems specifically for vulnerability.
• Security measures should already be built in during development – according to the “shift-left” approach for early protection.

Choose a cloud provider carefully

• Check security certificates and demand verifiable standards such as ISO 27001.
• Understand the shared responsibility model and clearly define which security aspects are the responsibility of the provider and which are your own.

Securing multi-cloud environments

• Implement central security guidelines: Uniform standards for all cloud platforms.
• Integration of security solutions: Connecting tools and monitoring systems to avoid gaps.

Conclusion

This checklist lays the foundation for a comprehensively secured cloud infrastructure. The combination of technical protection mechanisms, clear processes and trained employees significantly reduces risks and ensures a high level of security – regardless of whether you operate one or more cloud platforms.
