NAMEauditadm_r − Audit administrator role - Security Enhanced Linux Policy
DESCRIPTIONSELinux supports Roles Based Access Control (RBAC), some Linux roles are login roles, while other roles need to be transition into. Note: Examples in this man page will use the staff_u SELinux user. Non login roles are usually used for administrative tasks. For example, tasks that require root privileges. Roles control which types a user can run processes with. Roles often have default types assigned to them. The default type for the auditadm_r role is auditadm_t. The newrole program to transition directly to this role. newrole -r auditadm_r -t auditadm_t sudo is the preferred method to do transition from one role to another. You setup sudo to transition to auditadm_r by adding a similar line to the /etc/sudoers file. USERNAME ALL=(ALL) ROLE=auditadm_r TYPE=auditadm_t COMMAND
sudo will run COMMAND as staff_u:auditadm_r:auditadm_t:LEVEL When using a non login role, you need to setup SELinux so that your SELinux user can reach auditadm_r role. Execute the following to see all of the assigned SELinux roles: semanage user -l You need to add auditadm_r to the staff_u user. You could setup the staff_u user to be able to use the auditadm_r role with a command like: $ semanage user -m -R 'staff_r system_r auditadm_r' staff_u SELinux policy also controls which roles can transition to a different role. You can list these rules using the following command. search --role_allow SELinux policy allows the sysadm_r, staff_r, secadm_r roles can transition to the auditadm_r role.
BOOLEANSSELinux policy is customizable based on least access required. auditadm policy is extremely flexible and has several booleans that allow you to manipulate the policy and run auditadm with the tightest access possible. If you want to deny user domains applications to map a memory region as both executable and writable, this is dangerous and the executable should be reported in bugzilla, you must turn on the deny_execmem boolean. Enabled by default. setsebool -P deny_execmem 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 execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default. setsebool -P fips_mode 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 unconfined executables to make their stack executable. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla, you must turn on the selinuxuser_execstack boolean. Enabled by default. setsebool -P selinuxuser_execstack 1
MANAGED FILESThe SELinux process type auditadm_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.
auditd_etc_t /etc/audit(/.*)?
auditd_log_t /var/log/audit(/.*)?
/var/log/audit.log.*
screen_home_t /root/.screen(/.*)?
/home/[^/]+/.screen(/.*)?
/home/[^/]+/.screenrc
/home/[^/]+/.tmux.conf
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.
