The Good
Significant advancements in cybersecurity measures have been made recently by the U.S. General Services Administration (GSA). It has taken two important steps: enhancing identity verification with a new program and allocating significant funds to fortify the cybersecurity posture of the Department of Labor and Environmental Protection Agency. In a notable move towards enhancing vulnerability assessment, the Forum of Incident Response and Security Teams (FIRST) has publicly launched CVSS 4.0.
- The GSA released a new program roadmap to improve the identity and verification capabilities of Login[.]gov and comply with security standards. Meanwhile, the GSA’s Technology Modernization Fund set aside five new investments to improve the cybersecurity postures for the Department of Labor and Environmental Protection Agency. While the Labor Department will use $15.2 million for zero-trust architecture, the EPA will invest its $2.5 million into the security of its analytical radiation data system.
- A new version of the Common Vulnerability Scoring System (CVSS 4.0), which solves the loopholes discovered in CVSS version 3.1, has been unveiled by the Forum of Incident Response and Security Teams (FIRST). Some of the improvements include the addition of new base metrics, a focus on OT/ICS/safety systems, and enhanced disclosure of impact metrics.
- New regulations were proposed by the U.S. Federal Communications Commission to safeguard customer accounts from SIM switching and port-out scams. Under the proposed rules, wireless operators would have to deploy secure methods of user authentication before moving a SIM card to a new device or a phone number to a different network.
