Zero Trust in Resilient Cloud and Network Architectures
Autor Josh Halley, Dhrumil Prajapati, Ariel Leza, Vinay Sainien Limba Engleză Paperback – 29 aug 2025
Resursele tehnice care însoțesc acest volum, în special scripturile de automatizare bazate pe Terraform și Ansible, transformă Zero Trust in Resilient Cloud and Network Architectures dintr-un tratat teoretic într-un instrument de lucru indispensabil pentru inginerii de sistem. Considerăm că forța acestei lucrări rezidă în expertiza colectivă a autorilor Josh Halley, Dhrumil Prajapati, Ariel Leza și Vinay Saini, toți specialiști seniori în cadrul Cisco, care aduc în fața cititorului arhitecturi testate în medii de producție critice. Pe linia practică a lui Zero Trust Networks, dar cu focus pe reziliența rețelelor și integrarea hibridă, acest titlu explorează tranziția de la prototipuri la infrastructuri la scară largă. Structura este una tehnică și aplicată, abordând segmente critice precum Meraki, EVPN și protocoalele Pub/Sub. Dincolo de securizarea perimetrului, autorii analizează supraviețuirea rețelei în condiții de stres și introduc concepte de avangardă, cum ar fi securitatea cuantică și Industrial Zero Trust. Reținem rigurozitatea cu care sunt tratate procesele de segmentare și autentificare, esențiale pentru atenuarea riscurilor asociate dispozitivelor IoT. Spre deosebire de alte introduceri în domeniu, cum este Zero-trust – An Introduction, care oferă o privire de ansamblu asupra conceptului, volumul de față se scufundă în detalii de implementare specifice ecosistemului Cisco și cloud-ului rezilient. Cele peste 800 de pagini oferă o perspectivă granulară asupra modului în care fluxurile de trafic pot fi gestionate automatizat, asigurând o punte solidă între mediile on-premise și cele cloud.
