• Key Concepts: 
  Simple and Protected GSS API Negotiation Mechanism (SPNEGO) is a security component of the SAP BC-SEC Security module. It is a mechanism that allows for secure authentication and authorization between two systems, such as a client and a server. SPNEGO is based on the Generic Security Services Application Program Interface (GSSAPI), which is an industry standard for secure authentication and authorization. 
  
  How to use it: 
  SPNEGO can be used to authenticate users and authorize access to resources. It works by exchanging tokens between the client and server, which are then used to authenticate the user and authorize access to the requested resource. The tokens are encrypted using a shared secret key, which ensures that only authorized users can access the resource. 
  
  Tips & Tricks: 
  When using SPNEGO, it is important to ensure that the shared secret key is kept secure. Additionally, it is important to ensure that the tokens are not intercepted or tampered with during transmission.
