Shifting from traditional perimeter-based security
As discussed, Zero Trust represents a fundamental shift from the traditional perimeter-based security approaches that have long dominated cybersecurity. This paradigm shift is driven by the recognition that traditional security models are no longer sufficient to protect organizations from the rapidly evolving threat landscape and the transformation of IT infrastructure brought about by new innovations.
The “castle-and-moat” approach relies on the premise that internal systems and users within a network are inherently trustworthy, while external threats must be kept at bay. This approach focuses on establishing a strong perimeter around the organization’s resources, using firewalls, intrusion detection and prevention systems (IDPS), and other security measures to prevent unauthorized access.
