Security-Enhanced Linux secures the aide processes via flexible mandatory access control.
The aide processes execute with the aide_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep aide_t
The aide_t SELinux type can be entered via the aide_exec_t file type.
The default entrypoint paths for the aide_t domain are the following:
SELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to psbP
Policy governs the access confined processes have to files. SELinux aide policy is very flexible allowing users to setup their aide processes in as secure a method as possible.
The following process types are defined for aide:
Note: semanage permissive -a aide_t can be used to make the process type aide_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
SELinux policy is customizable based on least access required. aide policy is extremely flexible and has several booleans that allow you to manipulate the policy and run aide with the tightest access possible.
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
The SELinux process type aide_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
SELinux requires files to have an extended attribute to define the file type.
You can see the context of a file using the -Z option to lsbP
Policy governs the access confined processes have to these files. SELinux aide policy is very flexible allowing users to setup their aide processes in as secure a method as possible.
aide policy stores data with multiple different file context types under the /var/log/aide directory. If you would like to store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this data under the /srv directory you would execute the following command:
semanage fcontext -a -e /var/log/aide /srv/aide
restorecon -R -v /srv/aide
STANDARD FILE CONTEXT
SELinux defines the file context types for the aide, if you wanted to store files with these types in a diffent paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t aide_db_t '/srv/myaide_content(/.*)?'
restorecon -R -v /srv/myaide_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for aide:
- Set files with the aide_db_t type, if you want to treat the files as aide database content.
- Set files with the aide_exec_t type, if you want to transition an executable to the aide_t domain.
- Set files with the aide_log_t type, if you want to treat the data as aide log data, usually stored under the /var/log directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
semanage fcontext can also be used to manipulate default file context mappings.
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
