Zero Trust Architecture: Moving Beyond Perimeter-Based Security
Network perimeters have dissolved. The traditional castle-and-moat approach to security died the moment cloud services and remote work became standard practice. Yet many organisations still cling to outdated models. Zero trust architecture represents a fundamental shift in thinking. The core principle sounds simple: never trust, always verify. Implementation proves far more complex than that pithy phrase suggests. The assumption that internal networks are inherently safe has caused countless breaches. Attackers who gain initial access through phishing or compromised credentials move laterally with ease across flat networks.
