Removing the /etc/rc.dt file

Although running the CDE interface is convenient for users, security issues are associated with it. For this reason, do not run CDE on servers that require a high level of security. The best solution is to avoid installing CDE (dt) file sets. If you have installed these file sets on your system, consider uninstalling them, especially the /etc/rc.dt script, which starts CDE.

For more information about CDE, see the Operating system and device management.
