The 7 tenets of zero trust provided in NIST SP 800-207, are an attempt to define what should be included in a zero trust architecture instead of what should be excluded. Several authors define zero trust in terms of what should be excluded, like perimeters. But these attempts, go back to the use of perimeters…

A next generation firewall is a must-have in nowadays cybersecurity environments. NGFWs improve traditional firewalls in many ways, to improve network security. According to Gardner, “Next-generation firewalls (NGFWs) are deep-packet inspection firewalls that move beyond port/protocol inspection and blocking to add application-level inspection, intrusion prevention, and bringing intelligence from outside the firewall”. So, let’s start…

Zero trust architecture (ZTA) provides us with tools and principles to increase security in enterprise networks. This effort becomes especially relevant nowadays with the increase in cybersecurity threats and attacks. A zero trust architecture assumes that an attacker is always present in the network and therefore, access to every resource is denied by default until…
