• Key Concepts: 
  A guarded section is a feature of the ABAP Runtime Environment (BC-ABA) that allows for the protection of critical code sections. It ensures that only authorized users can access and modify the code, thus preventing unauthorized changes. It also helps to ensure that the code is not corrupted or tampered with. 
  
  How to use it: 
  To use a guarded section, you must first create a protected area in your code. This can be done by using the ABAP statement “GUARDED SECTION”. Once this statement is used, any code within the protected area will be inaccessible to unauthorized users. To access the code, you must provide a valid authorization key. 
  
  Tips & Tricks: 
  When creating a guarded section, it is important to ensure that the authorization key is kept secure. It should not be shared with anyone who does not have the necessary authorization to access the code. Additionally, it is important to regularly review and update the authorization key to ensure that it remains secure.
