Basic steps to secure your cloud without overspending
Securing your cloud environment is crucial for protecting your data and ensuring the safety and integrity of your applications. Here are the basic steps you should take to secure your cloud. And remember you do not necessarily need to run into expensive third party software to secure your cloud, most of the general use cases can be covered with the native services from your cloud provider, looking into third party software only for certain use cases.
1.Secure Identity and Access Management (IAM)
Use your provider’s IAM tools to manage access and permissions.
-Implement the Principle of Least Privilege: Provide users and services with only the permissions they need to perform their roles.
-Use Multi-Factor Authentication (MFA): Require additional verification beyond a password for accessing cloud resources.
-Regularly Review and Update Policies: Keep your IAM policies up-to-date and remove unused or outdated permissions.
2. Protect networking and VPC design
– Set Up Secure Network Architecture: Use private subnets and limit public-facing resources to what is necessary.
– Configure Security Groups and Network ACLs: Define rules to control traffic flow and access at different layers of your network.
– Use Firewalls: Use cloud-native firewall services and network security groups to protect your resources.
3. Encrypt data in transit and at rest
Utilize your provider’s encryption services for data at rest and in transit.
– Use Secure Communication Protocols: Encrypt data in transit using TLS or other secure protocols.
– Encrypt Data at Rest: Use cloud-native encryption services to protect stored data.
– Manage Encryption Keys Securely: Use a cloud-based key management service (KMS) for generating, storing, and accessing encryption keys.
4. Monitor and audit regularly
Cloud providers offer monitoring and logging services that can help you track activity and detect anomalies.
– Implement Monitoring Tools: Use cloud-native monitoring services to track resource usage, application performance, and potential security threats.
– Set Up Alerts and Notifications: Configure alerts to notify your team of any suspicious activities or anomalies.
– Conduct Regular Audits: Perform audits of access logs and usage reports to ensure compliance with security policies.
5. Control logging and storage costs
– Establish Log Retention Policies: Determine how long logs should be retained based on your needs and regulatory requirements.
– Optimize Storage Solutions: Archive or delete old logs when they are no longer needed to save on storage costs.
6. Develop and test incident response plans
– Prepare for Security Incidents: Have a clear plan in place for responding to security breaches, including containment, eradication, and recovery.
– Test Your Response Plans: Regularly conduct drills and simulations to ensure your team is ready to handle incidents effectively.
7. Stay informed and up-to-Date
– Keep Software Updated: Apply security patches and updates to your operating systems, applications, and dependencies.
– Stay Informed About Threats: Keep up with the latest security threats and best practices for your cloud provider.
– Training and Awareness: Ensure your team is trained on security best practices and aware of potential threats.

You don’t necessarily need specific, expensive software to protect your cloud environment. Cloud providers offer built-in security features and tools that can help you secure your environment effectively without the need for third-party software. Though you may still want to choose third-party tools for specific use cases (be aware of their costs and dependencies):
– Security Information and Event Management (SIEM): These tools aggregate and analyze security logs from multiple sources.
– Intrusion Detection and Prevention Systems (IDPS): Detect and prevent potential threats within your environment.
– Security Scanning and Vulnerability Assessment: Tools for scanning your cloud environment for vulnerabilities and misconfigurations.
Conclusion
While specialized software can add layers of protection, the built-in security features provided by cloud service providers, combined with good security practices and vigilance, can help you protect your cloud environment effectively. By making use of the tools and services your provider offers and supplementing them with third-party tools as needed, you can build a top secure and efficient cloud strategy without incurring unnecessary costs.
