A new, cloud-centric world
DevOps and security teams often work in parallel, leading to more secure applications. While protecting applications inherently through this approach has been positive for DevOps and other teams involved, recent events like Log4J/Log4Shell show that software vulnerabilities are inevitable, regardless of this close collaboration.
Because vulnerabilities will occur, it is important to implement controls at the other layers of the stack to keep your organization protected against bad actors looking for windows of opportunity. In the case of mitigating risk within cloud environments, adding defensive layers outside of the application, such as through network security controls at the cloud edge and the application VPC (virtual private cloud) edge, organizations can close those windows of opportunity. The challenge is that legacy network security enforcement points work in the cloud, but are not designed to support the sheer scale of the cloud or solve multicloud problems in a cloud native way, increasing management complexity and cost for achieving a comprehensive security posture. And while each cloud provider has its own stack of network security tools, they are often limited to a single cloud region. They don’t protect all cloud services or work across cloud providers, limiting an organization from reaching a comprehensive multicloud security strategy.
Network security controls are critical in the cloud and must adapt to today’s modern multicloud world. This ebook will help cloud architects understand how to design security models for organizations with applications and workloads deployed across multiple public clouds and private data centers.
Unlike the static nature of traditional on-premises environments, the nature of the cloud is much more dynamic, containing ephemeral workloads, fluctuating network addresses, elasticity, automation, and seamless scalability. Your cloud security architecture must adapt to this dynamic ecosystem by providing automated protection while learning and adapting to the environment itself.
