Lucas Masson discusses the challenges of securing modern production systems, emphasizing the need for comprehensive security measures amid the complexities of distributed systems and microservices. The introduction of Datadog Application Security Management (ASM) aims to address these challenges by providing integrated security solutions within the Cloud Security Platform. ASM enables teams to receive alerts on significant threats, identify authenticated attackers, assess the impact of attacks, and gain code-level insights for remediation. It offers coverage for various vulnerabilities, including SQL injections and cross-site scripting, and facilitates a unified view of attack vectors across the stack, enhancing collaboration between security and engineering teams. The ASM system is designed to be easily integrated with existing Datadog services, allowing users to quickly implement it without additional agents or traffic redirection.
