The failure of legacy on-premises infrastructure during the COVID-19 pandemic demonstrated its inability to provide the services that it was initially designed for. The tremendous load placed on these systems meant that they were unable to support complex, critical and “supposedly” elastic infrastructure. This inadequacy prompted the shift to cloud.
For most organizations, the shift to cloud has always created a complex security challenge. The intricacy of cloud services, SaaS applications, microservices, elastic resource scaling, mobile devices and an ever-increasing attack landscape makes security and visibility even harder. As organizations shift their data and applications to the cloud, security can become an afterthought, as many assume that it’s the vendor’s responsibility. However, security is a shared responsibility between the organization and the cloud vendor across the entire infrastructure, both on premises and in the cloud. As legacy systems are migrated to the cloud, planning and addressing the security of these systems is critical.
