NAME
sos clean - Obfuscate sensitive data from one or more sosreports
SYNOPSIS
sos clean TARGET [options]
[--domains]
[--disable-parsers]
[--keywords]
[--keyword-file]
[--map-file]
[--jobs]
[--no-update]
[--keep-binary-files]
[--archive-type]
DESCRIPTION
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 pro-
cessing executed during report generation, for example IP addresses.
Data obfuscated via this utility is done so consistently, meaning for example an IP ad-
dress 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 persis-
tently 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 be-
tween unprocessed and obfuscated elements will be written in the same location as the re-
sulting archive. This mapping file should be kept private by system administrators.
REQUIRED ARGUMENTS
TARGET
The path to the archive that is to be obfuscated. This may be an archive or an unbuilt sos
temporary
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.
OPTIONS
--domains DOMAINS
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 obfus-
cated, as will 'www.redhat.com' and subdomains such as 'foo.redhat.com'.
--disable-parsers PARSERS
Provide a comma-delimited list of parsers to disable when cleaning an archive. By
default all parsers are enabled.
Note that using this option is very likely to leave sensitive information in place
in the target archive, so only use this option when absolutely necessary or you
have complete trust in the party/parties that may handle the generated report.
Valid values for this option are currently: hostname, ip, ipv6, mac, keyword, and
username.
--keywords KEYWORDS
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.
--keyword-file FILE
Provide a file that contains a list of keywords that should be obfuscated. Each
word must be specified on a newline within the file.
--map-file FILE
Provide a location to a valid mapping file to use as a reference for existing ob-
fuscation 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/de-
fault_mapping so that consistency is maintained by default. Users may use this op-
tion to reference a map file from a different run (perhaps one that was done on an-
other system).
Default: /etc/sos/cleaner/default_mapping
--jobs JOBS
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
--no-update
Do not write the mapping file contents to /etc/sos/cleaner/default_mapping
--keep-binary-files
Keep unprocessable binary files in the archive, rather than removing them.
Note that binary files cannot be obfuscated, and thus keeping them in the archive
may result in otherwise sensitive information being included in the final archive.
Users should review any archive that keeps binary files in place before sending to
a third party.
Default: False (remove encountered binary files)
--archive-type TYPE
Specify the type of archive that TARGET was generated as. When sos inspects a TAR-
GET archive, it tries to identify what type of archive it is. For example, it may
be a report generated by sos report, or a collection of those reports generated by
sos collect, which require separate approaches.
This option may be useful if a given TARGET archive is known to be of a specific
type, but due to unknown reasons or some malformed/missing information in the ar-
chive directly, that is not properly identified by sos.
The following are accepted values for this option:
auto Automatically detect the archive type
report An archive generated by sos report
collect An archive generated by sos collect
insights An archive generated by the insights-client package
The following may also be used, however note that these do not attempt to pre-load
any information from the archives into the parsers. This means that, among other
limitations, items like host and domain names may not be obfuscated unless an ob-
fuscated mapping already exists on the system from a previous execution.
data-dir A plain directory on the filesystem.
tarball A generic tar archive not associated with any known tool
