Since 2012, the federal government has proposed or released a myriad of cybersecurity guidelines in effort to reduce cyber risks. While many of the guidelines remain voluntary, entities seeking to contract with the federal government must adhere to certain mandatory requirements, e.g., safeguarding unclassified controlled technical information. Additional mandatory regulations that have been proposed concern safeguarding contractor information systems and reporting data breaches, and are due for imminent release. Entities – federal government contractors in particular – should be mindful of these recent developments and take steps toward navigating the cybersecurity regulatory landscape. This recent development guide provides an overview of the cybersecurity regulatory landscape, but is tailored to federal government contractors. The guide also includes step by step checklists for the current and imminent mandatory regulations.
