The evolution of cloud security: Lessons from the past to navigate the future

Cloud security has evolved significantly from the early days of antivirus software to the current need for sophisticated cloud detection and response (CDR) solutions, reflecting lessons learned from past cybersecurity developments. Initially, endpoint security focused on antivirus programs that used signature-based methods to protect against known threats, but attackers soon adapted with polymorphic malware, leading to the development of next-generation antivirus and endpoint detection and response (EDR) software. However, as organizations migrated to the cloud, the inadequacies of on-premises security tools became apparent, prompting the emergence of cloud-specific solutions like cloud security posture management (CSPM) and cloud infrastructure entitlement management (CIEM). While these tools were effective in prevention, the complexity and speed of cloud threats highlighted the necessity for real-time detection and response capabilities uniquely designed for cloud environments. Consequently, CDR solutions have been developed to offer advanced threat detection, investigation acceleration, and automated response in diverse cloud infrastructures, enabling security teams to effectively manage and mitigate threats in real-time, ensuring robust cloud security.
