On May 12, the Biden Administration issued an “Executive Order on Improving the Nation’s Cybersecurity.”  The Order seeks to strengthen the federal government’s ability to respond to and prevent cybersecurity threats, including by modernizing federal networks, enhancing the federal government’s software supply chain security, implementing enhanced cybersecurity practices and procedures in the federal government, and creating government-wide plans for incident response.  The Order covers a wide array of issues and processes, setting numerous deadlines for recommendations and actions by federal agencies, and focusing on enhancing the protection of federal networks in partnership with the service providers on which federal agencies rely.  Private sector entities, including federal contractors and service providers, will have opportunities to provide input to some of these actions.…

Today, Susan Cassidy, Ashden Fein, Moriah Daugherty, and Melinda Lewis posted an article on Inside Government Contracts about the June 19, 2019 announcement by the National Institute of Standards and Technology (“NIST”) of the long-awaited update to Special Publication (“SP”) 800-171 Rev. 1, Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations.

The update…

On March 26, 2019, the Senate Armed Services’ Subcommittee on Cybersecurity held a hearing to receive testimony assessing how the Department of Defense’s (“DOD”) cybersecurity policies and regulations have affected the Defense Industrial Base (“DIB”).

Since August 2015, defense contractors have been on notice that they were required to implement the security controls in National Institute of Standards and Technology (“NIST”) Special Publication (“SP”) 800-171 no later than December 31, 2017 on covered contractor information systems. Although the focus has been…

On December 20, 2017, the National Institute of Standards and Technology (“NIST”) held a live webcast to discuss the draft updates to the Framework for Improving Critical Infrastructure Cybersecurity (“the Cybersecurity Framework”) and the Roadmap for Improving Critical Infrastructure Cybersecurity (“the Roadmap”). Although the webcast is not currently available online, NIST plans to publish a recording of the live webcast in early January 2018.

During this webcast, NIST provided an overview of the updates to Version 1.1 of the Cybersecurity Framework (“Version 1.1”), which were analyzed in previous blog posts on Inside Privacy and Inside Government Contracts. The webcast included a discussion of the following topics:…

Ahead of the upcoming December 31, 2017 deadline for federal defense contractors to implement the security controls of National Institute of Standards and Technology (“NIST”) Special Publication 800-171 (“SP 800-171”), NIST has released a new draft publication designed to assist organizations in assessing compliance under SP 800-171, Draft Special Publication 800-171A, Assessing Security Requirements for Controlled Unclassified Information (“CUI”) (“SP 800-171A”).

Currently, there is no regulation or statute that imposes SP 800-171A on contractors. Rather, SP 800-171A is intended as guidance for organizations in developing assessment plans and conducting “efficient, effective, and cost-effective” assessments of the implementation of security controls required by SP 800-171. Similar to SP 800-171, SP 800-171A does not prescribe specific, required assessment procedures. Instead, SP 800-171A provides a series of “flexible and tailorable” procedures that organizations could use for conducting assessments with each security control in SP 800-171. SP 800-171A specifically recognizes three distinct methods for conducting assessments: examining and interviewing to facilitate understanding, achieve clarification, or obtain evidence and testing to compare actual results with expectations.…
