Custom permissions for InfoScale log files
To comply 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 component-specific tunable parameters that let you modify the corresponding log file permissions as needed.
Table: InfoScale tunable parameter
InfoScale component | Tunable parameter | Located in file |
---|---|---|
VxFS | eo_perm |
|
VxVM | log_file_permissions |
|
VCS |
|
|
VxCPServ | VCS_ENABLE_PUBSEC_LOG_PERM |
|
DBED | VCS_ENABLE_PUBSEC_LOG_PERM |
|
InfoScale Operations Manager | log_file_permissions |
|
The following table lists the parameter values and the corresponding log file permissions that are applicable when those values are set. These values are applicable to all the InfoScale components.
Table: Tunable parameter values, file permissions, and behavior
Tunable parameter value | Log file permissions | Behavior |
---|---|---|
0 (default) | 600 | Update existing file permissions on upgrade. |
1 | 640 | Update existing file permissions on upgrade. |
2 | 644 | Update existing file permissions on upgrade. |
10 | 600 | Do not change existing file permissions on upgrade. |
11 | 640 | Do not change existing file permissions on upgrade. |
12 | 644 | Do not change existing file permissions on upgrade. |
