📅 - Zero Trust Security: Rebuilding Enterprise Cyber Defenses - The traditional model of cybersecurity, which relies heavily on securing the perimeter of trusted internal networks, is increasingly viewed as inadequate in the face of modern cyber threats. Enterprises today confront sophisticated adversaries capable of exploiting vulnerabilities and compromised credentials, effectively bypassing perimeter defenses.
As a result, a growing number of organizations are shifting towards a zero trust security model - a paradigm that eliminates the concept of implicit trust within a network and instead requires verification of every access request, regardless of user location or device.
The zero trust approach, originating from concepts introduced by Stephen [...]
