Describe the security and authorization concepts in ABAP development and how they are implemented.

Security and authorization are critical aspects of ABAP development to protect sensitive data and ensure that system resources are accessed only by authorized users. ABAP provides various security features and authorization concepts that can be implemented to enforce access control. Here's an in-depth explanation of these concepts: 1. User Management: ABAP offers user management capabilities to create and manage user accounts. User accounts are used to authenticate individuals accessing the system. User credentials, such as username and password, are verified during login to ensure the identity of the user. User management includes features like password policies, user lockout mechanisms, and user role assignment. 2.
