Security Guidelines for ABAPThis guide is to provide developers with an overview of the security aspects and recommendations for ABAP applications.

This documentation is divided into the following sections. A. The SAP Authorization Concept The ABAP authorization concept protects transactions, programs, and services in SAP systems from unauthorized access. On the basis of the authorization concept, the administrator assigns authorizations to the users that determine which actions a user can execute in the SAP system, after he or she has logged on to the system and authenticated himself or herself. To access business objects or execute SAP transactions, a user requires corresponding authorizations, as business objects or transactions are protected by authorization objects. The authorizations represent instances of generic authorization objects and are defined depending on the activity and responsibilities of the employee. The authorizations are combined in an authorization profile that is associated with a role. The user administrators then assign the corresponding roles using the user master record, so that the user can use the appropriate transactions for his or her tasks. The following graphic shows the authorization components and their relationships. Explanation of the graphic Single Role Single Role is created with the role administration tool and allows the automatic generation of an authorization profile. The role contains the authorization data and the logon menu for the user. Composite Role Consists of any number of single roles. Generated authorization profile Is generated in role administration from the role data. Composite profile Consists of any number of authorization profiles. How To Uninstall Ansys 14. Authorization Definition of an authorization object, that is, a combination of permissible values in each authorization field of an authorization object. Authorizations allow you to specify any number of single values or value ranges for a field of an authorization object. You can also allow all values, or allow an empty field as a permissible value. If you change authorizations, all users whose authorization profile contains these authorizations are affected. Authorization object An authorization object allows complex tests of an authorization for multiple conditions. Authorizations allow users to execute actions within the system. For an authorization check to be successful, all field values of the authorization object must be appropriately entered in the user master record. Authorization field Contains the value that you defined. It is connected to the data elements stored with the ABAP Dictionary. B. Security Logging Concept. SAP Systems keep a variety of logs for system administration, monitoring, problem solving, and auditing purposes. Audits and logs are important for monitoring the security of your system and to track events in case of problems. SAP Systems offer different frameworks for logging data changes as well as events. For an overview of the different frameworks provided, please see the following table Data Type Events Framework.

C. Handling User names and passwords. User ID and Password Authentication prevents unauthorized access to the system This helps in maintaining data privacy, integrity and safeguards critical information. User ID and password authentication enables you to enforce access control to the ABAP systems with an authentication mechanism that offers basic access protection with relatively low complexity of security configuration tasks. The following guidelines can be followed while developing and application in ABAP that requires user authentication. The password should be displayed in the screen using asterisk. Do not display in plain text. The password should be always saved using hash value. Avoid the administrator to gain access to the password. Use secure hash functions to prevent password recovery. Do not hard code passwords in the source code. Passwords in the source code are not protected from inspection. Do not record passwords in logprotocoltrace files. Use encryption and decryption feature to protect the password. Do not use HTTP GET requests since all parameters will be found in the URL. Use HTTP POST requests instead. In general, you should avoid transmitting passwords, in particular with every request you send. Use secure mechanisms instead, such as digital certificates for example. Passwords may also be displayed in readable form when tracing, depending on the trace settings. Do overwrite passwords in memory, otherwise they might still exist in memory even after completion of the application and could thus be read by a malicious application.
