What do PKI, SDL, and WAF represent in cloud security?

PKI, SDL, and WAF are all initiatives and technologies aimed at enhancing cloud security, which makes identifying them specifically as cloud security controls very accurate.

Public Key Infrastructure (PKI) provides a framework for managing digital certificates and encryption keys, ensuring secure data transmission. It plays a crucial role in user authentication and data integrity within cloud environments.

Software Development Lifecycle (SDL) refers to a systematic process for developing software that emphasizes security at each stage. Implementing SDL in cloud applications enhances the overall security posture, addressing vulnerabilities throughout the development process.

Web Application Firewall (WAF) is a security solution designed to protect web applications by filtering and monitoring HTTP traffic between a web application and the internet. It helps mitigate various attacks targeting web applications, ensuring they operate securely in the cloud.

Each of these components directly contributes to strengthening the security mechanisms within a cloud framework, which confirms the designation of PKI, SDL, and WAF as essential cloud security controls.
