logwatch_mail_selinux: Security Enhanced Linux Policy for the logwatch_mail processes
NAMElogwatch_mail_selinux - Security Enhanced Linux Policy for the logwatch_mail processes
Security-Enhanced Linux secures the logwatch_mail processes via flexible mandatory access control.
The logwatch_mail processes execute with the logwatch_mail_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep logwatch_mail_t
The logwatch_mail_t SELinux type can be entered via the sendmail_exec_t, mta_exec_type, mta_exec_type file types.
The default entrypoint paths for the logwatch_mail_t domain are the following:
/usr/sbin/sendmail(.sendmail)?, /usr/bin/esmtp, /usr/sbin/rmail, /usr/sbin/ssmtp, /usr/lib/sendmail, /var/qmail/bin/sendmail, /usr/sbin/sendmail.postfix
PROCESS TYPESSELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux logwatch_mail policy is very flexible allowing users to setup their logwatch_mail processes in as secure a method as possible.
The following process types are defined for logwatch_mail:
Note: semanage permissive -a logwatch_mail_t can be used to make the process type logwatch_mail_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANSSELinux policy is customizable based on least access required. logwatch_mail policy is extremely flexible and has several booleans that allow you to manipulate the policy and run logwatch_mail with the tightest access possible.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlogin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by default.
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by default.
setsebool -P domain_kernel_load_modules 1
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
If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1
If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.
setsebool -P kerberos_enabled 1
If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Disabled by default.
setsebool -P nscd_use_shm 1
If you want to support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Disabled by default.
setsebool -P use_nfs_home_dirs 1
If you want to support SAMBA home directories, you must turn on the use_samba_home_dirs boolean. Disabled by default.
setsebool -P use_samba_home_dirs 1
The SELinux process type logwatch_mail_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.
COMMANDSsemanage 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.
