Overview

In response to increasing cybersecurity threats targeting operational technology (OT) networks, the Cybersecurity and Infrastructure Security Agency (CISA) and other federal agencies have released new guidelines recommending a zero trust approach for these systems. As industrial systems become more interconnected, the risks of cyberattacks grow, prompting the need for stronger security measures. The guidance aims to help organizations better protect their OT environments by adopting zero trust principles, which focus on verifying all users and devices before granting access to sensitive systems. This is particularly important as the reliance on digital technologies in industrial sectors continues to expand. Implementing these practices is crucial for safeguarding critical infrastructure against evolving cyber threats.

Program to rotate cyber personnel through federal agencies saw little use

CyberScoop

The Government Accountability Office (GAO) reported that the Federal Rotational Cyber Workforce program, designed to rotate cybersecurity professionals among federal agencies, has seen minimal participation. Only a handful of personnel received approval to join the initiative, which aims to enhance collaboration and knowledge sharing across government entities. This low engagement raises concerns about the effectiveness of the program in addressing the growing cybersecurity challenges faced by federal agencies. Without a more robust participation rate, the program may struggle to achieve its intended goals of improving cyber defense capabilities and developing a skilled workforce. The findings suggest a need for better incentives or support to encourage agencies to utilize this resource effectively.
