SAP Security Logs

As SAP systems are large and complex, ensuring an appropriate user management procedure is essential. SAP security logs record all activities performed in an SAP system, like system accesses, authorizations, and user management. By monitoring these logs, SAP administrators can detect potential incidents, threats and ensure compliance. Moreover, SAP security logs can include information that can ensure compliance with regulatory requirements like system parameters or system configuration settings.

Most Important SAP Security Logs 

There are many SAP security logs. However, there are some that are commonly used to protect system activities. The most important ones are:  

  1. Transaction Log – Documents all transactions executed within SAP systems. It tracks all changes made to business-critical data and finds threats like unusual user activity.  
  2. Security Audit Log – Documents all events relevant to the security of the system like user login activities, failed logins, and user information changes.  
  3. Change Log – This log is used to keep an eye on changes to critical systems and information to ensure compliance. It documents all changes made like configurations and customizations to objects and information within SAP.  
  4. Authorization Change Log – Documents all changes made to user authorizations. Looks further into user roles, access permissions, and profiles. 
  5. Transport log – This log provides information about the changes to programs and system updates. It documents all changes made to the SAP system during the transport process.  


Organizations must ensure they have the right tools to mitigate all threats and vulnerabilities. A unified platform like SecurityBridge can integrate with SAP security logs and monitor system activities. With SecurityBridge organizations gain full visibility into their SAP systems, including user activities, system changes, and more.
