Recent cyberattacks have revealed an uncomfortable truth: Public-sector data, networks and IT are less secure than agencies thought. Now, doubts exist that traditional, perimeter-based security can protect governments. To guarantee mission wins, agencies at every level need a new gold standard for cybersecurity. President Joe Biden’s executive order (EO) on cybersecurity could not have come at a better time. Instead of relying on outdated tactics, Biden’s EO directed America’s cybersecurity toward a new future: zero-trust security. This represents a big shift in how agencies think about security. In zero-trust security, all computing entities are deemed untrustworthy by default. Actively practicing zero-trust security also requires such unfamiliar concepts as continuous monitoring, network segmentation, identity and access management and the principle of least privilege. With such a steep learning curve, how can agencies quickly understand zero-trust security and align with the transformative details in Biden’s EO?
