Is the default umask set to a minimal value?
|The umask sets the default permission for files that you create. Bastille can set one of several umasks in the default login configuration files. These cover standard shells like csh and most bourne shell variants like bash, sh, and ksh. If you are going to install other shells, you may have to configure them yourself. The only reason not to set at least a minimal default umask is if you are sure that you have already set one.|
