Setting log file permissions
In compliance with the U.S. Presidential Executive Order (EO) 14028 (issued on May 12, 2021), all InfoScale log files permissions are set to 600 (rw-------) by default. Only the owner of the log files has full read-write access. However, this default value may not be suitable for all environments. In certain cases, there can be a need to set different values for the log file permissions. To address this requirement, InfoScale provides tunables that let you modify the log file permissions as needed.
To set InfoScale log file permissions
- You can set the InfoScale log file permissions in the following ways:
During InfoScale upgrade:
When you upgrade to InfoScale 9.0, the installer presents you with the following dialog during installation:
Do you want to set the permission of the files as per EO logging standards? [y,n,q]
When you enter y (Yes), the following dialog appears:
Please provide the proper permission option [b,q,?] (0)
The default is value is set as 0 (zero) and the permissions are set to 600 (read-write access to owner) for all log files. Enter the desired value here to set the required permission settings. For example, enter 10 to set the permissions to the default value of 600 (read-write access to owner), applicable to all new log files, but do not change any existing log file permissions.
Note that this value gets applied to all the InfoScale log files. Post upgrade, you can use the manual method to set permissions for log files at an individual component level.
Post InfoScale upgrade:
You can modify the log file permissions after the upgrade. Each InfoScale component has a unique tunable parameter to which you can assign a value to set the desired log file permissions for that component. You can do this manually using the relevant commands or by directly editing the individual component's configuration file.
Note:
When you set the permissions manually, you must restart the individual component service for the changes to take effect.
The log file permissions are set to the value that you provide, irrespective of whether you set the value during upgrade or post upgrade.
