Used for file transfers between the client computer and the network engine pre Release 10.1

Used by the Metasys system for Active Directory service authentication at the Metasys system login screen, and Service Account authentication prior to LDAP queries.

Kerberos is a standard network authentication protocol designed to provide strong authentication for client/server applications by using secret-key cryptography. Kerberos is the primary security protocol for authentication within an Active Directory service Domain. Kerberos authentication relies on client functionality built into the Windows operating systems supported by Metasys software.

Used by the Metasys system to access user objects and attributes within Active Directory service.

LDAP is a standard communication protocol for directories located on TCP/IP networks. LDAP defines how a directory client can access a directory server and how the client can perform directory operations and share directory data.

I/O

Metasys at 8.1 and higher uses HTTPS for communication between engines and the ADS/ADX/OAS and also between clients (SMP/MUI) and the ADS/ADX/OAS.

Required if you use SSL with your reporting ADX.

Required if you use TLS with the Metasys UI and the Johnson Controls System Configuration Tool (JCT) for site security.

Port 443 is used for secure web browser communication. Data transferred across such connections is highly resistant to eavesdropping and interception. Moreover, the identity of the remotely connected server can be verified with significant confidence. Web servers offering to accept and establish secure connections listen on this port for connections from web browsers desiring strong communication security.

With BFT, file transfers occur between the device and SCT where the device is the HTTPS client and SCT is the HTTPS server. 

Used during Metasys system SSO authentication.

NTLMv2 is a network authentication protocol developed by Microsoft and the secondary security protocol for authentication within an Active Directory service domain. If a domain client or domain server cannot use Kerberos authentication, then NTLM authentication is used.
