Check for permissions on the old user group when assigning a new user group to a user
Create permissions for customising
You can use the BAdI SMIME_EMAIL of the SMIME extension spot and implement the CERTIFICATE_RETRIEVAL and CERTIFICATE_SELECTION methods according to your requirements. This BAdI is called whenever an encrypted e-mail is sent. An extension allows you to search for a valid certificate at run time (for example, the one with the longest validity) to the recipient's email address in a source you defined. In the default implementation, the BAdI searches for the certificate in the Trust Manager's address book. For details on the availability of BAdIs, see SAP Note 1835509.
SNC secures communication with or between ABAP systems, but there are also many web-based applications in SAP system landscapes. They communicate via the Hypertext Transfer Protocol (HTTP). The data is also transmitted unencrypted when communicating via HTTP; Therefore, you should switch this communication to Hypertext Transfer Protocol Secure (HTTPS). HTTPS uses the encryption protocol Transport Layer Security (TLS) for secure data transfer on the Internet. You should therefore set up HTTPS for all users to access the Web. For communication between SAP systems, you should use HTTPS if you think the data transfer could be intercepted. You should either set up HTTPS on individual components of the infrastructure (such as proxies), or the ABAP systems should support HTTPS or TSL directly. Details of the configuration can be found in the SAPHinweis 510007.
Use SAP Code Vulnerability Analyser
In addition to SAP standard software, do you also use custom ABAP programmes? Learn how the SAP Code Vulnerability Analyser can scan your customer code for potential security vulnerabilities and resolve them if necessary. Permission concepts, firewalls, anti-virus and encryption programmes alone are not enough to protect your IT infrastructure and IT systems against internal and external attacks and misuse. Some of the risks are identified by potential security vulnerabilities in the ABAP code, most of which cannot be addressed by downstream measures and therefore need to be addressed in the code itself. It should also be noted that the permission concepts used can be circumvented by ABAP code, which underlines the weight of security vulnerabilities in the ABAP code. While SAP is responsible for providing security information to help close security vulnerabilities in standard code, it is up to you to address security vulnerabilities in custom ABAP programmes. Companies are subject to a whole range of legal requirements on data protection and data integrity, and you can fulfil them as far as possible with the help of a new tool. The SAP Code Vulnerability Analyser is integrated into the ABAP Test Cockpit (ATC) and thus available in all ABAP editors such as SE80, SE38, SE24, etc. Developers can use it to scan their code for vulnerabilities during programming and before releasing their tasks. This reduces testing costs and costs.
In the event that such conflicts nevertheless arise, regular checks should be established as part of an internal control system. Furthermore, the authorization concept includes content such as the integration of the data owner, security-relevant system settings, specifications for maintaining authorization default values (transaction SU24) and documentation requirements.
Authorizations can also be assigned via "Shortcut for SAP systems".
The Permissions check continues again if the table in question is a client-independent table.
Make sure that reference users are assigned minimal permissions to avoid overreaching dialogue user permissions.
