What is Zero Trust and is it the Future of Cybersecurity?
Zero Trust is a security architecture that assumes the network is already infiltrated and implements multi-factor authentication, least privilege access, and real-time monitoring and analytics to secure digital assets. The Zero Trust model goes beyond the traditional perimeter-based security method and focuses on protecting identities, endpoints, applications, data, infrastructure, and networks. By using a Zero Trust model, organizations can better protect themselves from cyber-attacks and data breaches while still making sure they are compliant and staying productive. Zero Trust is the future of cybersecurity because it focuses on visibility, automation, and orchestration. It is also the key to securing your digital estate.
Internet Traffic blocked in Edge Sandbox Mode (Windows Defender Application Guard)
I have successfully activated Windows Defender Application Guard but it seems surfing in Edge Sandbox Mode has been impossible. All required gpos and addition requirements as described on here: https://learn.microsoft.com/en-us/windows/security/application-security/application-isolation/microsoft-defender-application-guard/configure-md-app-guard https://learn.microsoft.com/en-us/windows/security/application-security/application-isolation/microsoft-defender-application-guard/faq-md-app-guard have been configured accordingly. I had a tip from microsoft support that my firewall could be blocking traffic (NAT)coming from the Host Computer so should allow all IP subnets in the range of 172.x.x.x or 192.x.x.x. I have tested that by allowing this traffic in the Trellix including Remote Ports 49700–65535, as described in Trellix documentation here https://kcm.trellix.com/corporate/index?page=content&id=KB88788 but to no avail. Could there be any other underlying root causes in a typical Enterprise environment where systems have been hardened using Security policies defined by CIS. What rules can be exempted here in order to allow this kind of traffic. Anybody has experience with this kind of environment or issue. Some tips will be welcomed.
