"It is first important to know and understand the asset within your ICS, IoT or IIoT environment. Moreover, it is important to understand the various points of integration. In order to do micro segmentation, it is important to segment the OT into five pillars," says Migriño.

"We have now recognized that existing security approaches are not enough. Therefore, in our sector, enterprise leaders are finding that the zero trust model could deliver best results. Not all technology components are available today, so we have begun by encryption of data in store and in transit," says Taborlupa.

In a video panel interview with Information Security Media Group, Migriño and Taborlupa also discuss:

  • How zero trust can be applied to legacy systems;
  • Where the National Task Force in the Philippines is on its zero trust journey;
