WBSP-AS-000790 - The WebSphere Application Server wsadmin file must be protected from unauthorized deletion.
Protecting log data also includes identifying and protecting the tools used to view and manipulate log data. Depending upon the log format and application, system and application log tools may provide the only means to manipulate and manage application and system log data. It is, therefore, imperative that access to log tools be controlled and protected from unauthorized modification. If an attacker were to delete log tools, the application server administrator would have no way of managing or viewing the logs. Application servers provide a web- and/or a command line-based management functionality for managing the application server log capabilities. In addition, subsets of log tool components may be stored on the file system as jar, class, or xml configuration files. The application server must ensure that in addition to protecting any web-based log tools, any file system-based tools are protected from unauthorized deletion as well.
On the system hosting the WebSphere application server, log on to the operating system with admin rights. Navigate to the 'WebSphere' folder, change permissions on the folder. Do not propagate permissions to sub-folders. For UNIX systems: set the 'WebSphere' folder permissions to '770'. For Windows systems: set 'WebSphere' folder permission to allow full control for SYSTEM, WebSphere user, and Admin Group. Do not propagate permissions to sub-folders.
