Request an in-depth attack surface analysis to see what apps and services you have exposed to the internet, vulnerable to attacks. Its also clear from the above that its important for all domains to be resolvable across trusts for Kerberos Authentication to function. The Zero Trust Certified Architect (ZTCA) path enables you to gain a clear understanding of the need to transform to a true zero trust architecture and be introduced to the three sections and seven elements one must understand when embarking on a zero trust journey. Replace risky and overloaded VPNs with next-gen ZTNA. o AD Site enumeration is necessary for DFS mount point calculation How to configure application segments and define applications within the Zscaler Private Access (ZPA) Admin Portal. most efficient), Client performs LDAP query to Domain Controller requesting capabilities, Client requests Kerberos LDAP Service Ticket from AD Domain Controller, Client performs LDAP bind using Kerberos (SASL), Client makes RPC call to Domain Controller (TCP/135) which returns unique port to connect to for GPO (high port range 49152-65535 configurable through registry), Client requests Group Policy Object for workstation via LDAP (SASL authenticated). In the context of automatic user provisioning, only the users and/or groups that have been assigned to an application in Azure AD are synchronized.
