sos clean - Obfuscate sensitive data from one or more sosreports

sos clean TARGET [options]
[--domains]
[--map]
[--jobs]
[--no-update]

sos clean or sos mask is an sos subcommand used to obfuscate sensitive information from previously generated sosreports that is not covered by the standard plugin-based post processing executed during report generation, for example IP addresses.

Data obfuscated via this utility is done so consistently, meaning for example an IP address of 192.168.1.1 in an unprocessed sosreport that gets obfuscated to, for example, 100.0.0.1, will be changed to 100.0.0.1 in all occurrences found in the report.

Additionally, by default all such obfuscations are stored in "maps" that will be persistently saved to /etc/sos/cleaner/default_mapping and be re-used on subsequent runs.

This utility may also be used in-line with sos report and sos collect by specifying the --clean or --mask option.

When called directly via sos clean, the obfuscated archive is written as an additional file, meaning the original unprocessed report still remains on the filesystem. When called via report or collect, the changes are done in-line and thus only an obfuscated archive is written and available. In either case, a mapping file containing the relationships between unprocessed and obfuscated elements will be written in the same location as the resulting archive. This mapping file should be kept private by system administrators.

TARGET

directory. If an archive, it will first be extracted and then after obfuscation is complete re-compressed using the same compression method as the original.

Provide a comma-delimited list of domain names to obfuscate, in addition to those matching the hostname of the system that created the sosreport. Subdomains that match a domain given via this option will also be obfuscated.

For example, if --domains redhat.com is specified, then 'redhat.com' will be obfuscated, as will 'www.redhat.com' and subdomains such as 'foo.redhat.com'.

Provide a comma-delimited list of keywords to scrub in addition to the default parsers.

Keywords provided by this option will be obfuscated as "obfuscatedwordX" where X is an integer based on the keyword's index in the parser. Note that keywords will be replaced as both standalone words and in substring matches.

Provide a location to a valid mapping file to use as a reference for existing obfuscation pairs. If one is found, the contents are loaded before parsing is started. This allows consistency between runs of this command for obfuscated pairs. By default, sos will write the generated private map file to /etc/sos/cleaner/default_mapping so that consistency is maintained by default. Users may use this option to reference a map file from a different run (perhaps one that was done on another system).

Default: /etc/sos/cleaner/default_mapping

The number of concurrent archives to process, if more than one. If this utility is called by sos collect then the value of the jobs option for that utility will be used here.

Default: 4

Do not write the mapping file contents to /etc/sos/cleaner/default_mapping
