U.S. Office of Management and Budget Directive: Federal Agencies Have 60 Days to Identify Critical Supply Chain Software

“If you see something say something, right?” The U.S. Office of Management and Budget (OMB) issued another memorandum last week calling for federal departments and agencies to report on critical software inventories and implement a plan to secure them. This is yet another in a series of government mandates aimed at hardening cyber defenses against increasing threats.

The M-21-30 OMB memo directs executives to catalog critical software assets in the next 60 days and, over the next year, implement the first phase of the guidance. The end game is to make the software supply chain more secure and protect the use of software in all operating environments, including cloud. The memo points to National Institute of Standards and Technology (NIST) guidelines to define “critical software;” the required cybersecurity measures needed in a multi-phased approach; and detailed instructions on how to best comply under the following timelines:

Requirement Deadline Responsible Body

1. Identify All Agency Critical Software, in Use or in the Acquisition Process

60 Days

All Agencies

2. Incorporate Security Measures for Specified Categories of Critical Software

1 Year

All Agencies

3. Incorporate Security Measures for Additional Software Categories Identified for Each Subsequent Phase

1 Year

All Agencies

4. Publish Updates to the Definition of Critical Software and Guidance for Security Measures

As necessary

NIST

5. Issue List of Software Categories to Be Included in Next Phase of Implementation

As necessary

CISA


What’s Missing? Speed, Sticks, Vendor Requirements and Testing

If you read the memo thoroughly and were left thinking something is missing, you’re not alone. In my view, OMB should be pushing for results much faster. Consider how much the threat landscape changes every week. A year from now we’ll be dealing with new challenges not yet imagined. We must get ahead of it, not further behind. Here are some things to consider:

First, cataloging critical or even operational software assets should be a straightforward task that is already part of any federal agency’s cybersecurity plan and audit process. Also, where is the stick? What happens if a federal department or agency doesn’t meet the deadlines … aside from a chance they’ll get breached?

Second, government entities are not the only culpable party here. Yes, they must ensure they purchase software from reputable supply chain vendors, but where is the focus on the vendors?

Software vendors for the federal government should be required to assure provenance and provide evidence and artifacts that their software has been thoroughly tested and validated against vulnerabilities. Perhaps another third-party independent validation and certification is in order. Vendors might complain about the extra cost, time to market etc., but the impact would be far less than if a breach is caused by their software.

Third, just because software complies with guidance from NIST, the Federal Informational Security Act (FISMA), the Federal Risk and Authorization Management Program (FedRAMP), Federal Informational Processing Standards (FIPS) and Common Criteria today doesn’t mean it’s secure tomorrow. Sophisticated red team testing can identify vulnerabilities before attackers do. This should be part of the guidance.

A Few Final Thoughts

Time is a critical variable in the cybersecurity defense conversation. Assuming you subscribe to the idea that to stay ahead of the adversary, you must adapt in near real time to the threat of the day. The latest OMB directive is good to see; yet, it doesn’t keep the government on par with the speed of adversaries.

But, let’s end with some good news. Awareness is growing all the time. Measures like those laid out in the White House Executive Order on Improving the Nation’s Cybersecurity, which requires a Zero Trust architecture, help move us closer to where we need to be. Time is of the essence, so if you’re still on the sidelines when it comes to implementing Zero Trust, get in the game now.
