1. Understand the FaaS provider’s security measures: A FaaS provider offers a secure environment for running functions. Some providers may have better security measures than others. It’s essential to research the provider and understand their security mechanisms.
1. Limit access to functions: Allow only authorized individuals to have access to the functions. Use access controls, such as IAM roles, to restrict access and grant permissions to specific resources.
1. Secure the code: Ensure that the code deployed on the FaaS platform is secure. Developers can do a security review of their code and use automated security tools to detect vulnerabilities.
1. Monitor function activity: Monitor function activity to detect suspicious behavior. Use logging and monitoring tools to analyze function activity and identify any security issues that may arise.
1. Use encryption: Deploy encryption mechanisms to protect sensitive data. Use TLS/SSL to encrypt data in transit and encrypt data at rest using encryption services offered by the FaaS provider.
1. Keep software up-to-date: Ensure that the FaaS platform and all software components are kept up-to-date. Follow the FaaS provider’s recommendations regarding updates and patches.
1. Disaster recovery and backups: Have a disaster recovery and backup plan in place. Regularly backup function code and data to ensure availability in case of any disruptions or attacks.
1. Testing: Test functions for security vulnerabilities during the development phase using testing tools and techniques.
1. Educate staff: Ensure that all staff members are aware of security best practices and the importance of following security procedures when working with functions deployed on the FaaS platform.
