With the implementation of the President's Executive Order (EO) on Improving the Nation's Cybersecurity, public sector agencies were placed under immense pressure to increase adoption of emerging technologies as part of an enhanced approach to cybersecurity through initiatives related to software supply chain security and integrity. Looking back one year later, how has the nation's cybersecurity improved and what still needs to be done? What do things look like for public sector agencies moving forward? During this Public Sector Virtual Roundtable, World Wide Technology (WWT) and GitLab will look back at the Cyber EO – analyzing its immediate impact, how agencies reacted and responded, and the lasting significance of overhauling our national approach to cybersecurity. The event will also feature a demonstration of how agencies can implement the latest NIST requirements into their cybersecurity strategy to adhere to the EO mandates, leveraging the DevOps and DevSecOps best practices.
