• Key Concepts: 
  Secure Network Communication (SNC) is a security component of the SAP Basis layer that provides authentication and encryption services for communication between SAP systems and external applications. It is based on the public-key infrastructure (PKI) and uses the X.509 standard for authentication and encryption. SNC is part of the BC-SEC Security component of SAP Basis. 
  
  How to use it: 
  SNC can be used to secure communication between SAP systems and external applications, such as web services, databases, or other applications. It can also be used to secure communication between different SAP systems. To use SNC, you must first configure the SNC parameters in the SAP system. This includes setting up the SNC partner profile, which defines the authentication and encryption algorithms to be used for communication with external applications. 
  
  Tips & Tricks: 
  When configuring SNC, it is important to ensure that the correct authentication and encryption algorithms are used for each partner profile. It is also important to ensure that the correct certificates are used for authentication and encryption.
