With a number of high-profile security hacks involving widely used software, government agencies are retraining their focus on their organization's security measures and those of the vendors and service providers that work with them. This shift in focus was actually on the rise before the recent hacks in anticipation of cyberattacks just like the ones we've recently seen.
In January of 2020, the Defense Department implemented the Cybersecurity Maturity Model Certification (CMMC), a unified standard for implementing cybersecurity across the defense industrial base (DIB), which includes over 300,000 companies in the supply chain. Contractors have always been held responsible for implementing and documenting their IT systems' security that touch sensitive government data. Under CMMC, this continues, but adds the need for a third party to assess the contractor's compliance.
