mysqlmanagerd_selinux: Security Enhanced Linux Policy for the mysqlmanagerd processes

NAME

mysqlmanagerd_selinux - Security Enhanced Linux Policy for the mysqlmanagerd processes

DESCRIPTION

Security-Enhanced Linux secures the mysqlmanagerd processes via flexible mandatory access control.

The mysqlmanagerd processes execute with the mysqlmanagerd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep mysqlmanagerd_t

ENTRYPOINTS

The mysqlmanagerd_t SELinux type can be entered via the mysqlmanagerd_exec_t file type.

The default entrypoint paths for the mysqlmanagerd_t domain are the following:

/usr/sbin/mysqlmanager

PROCESS TYPES

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 psP Policy governs the access confined processes have to files. SELinux mysqlmanagerd policy is very flexible allowing users to setup their mysqlmanagerd processes in as secure a method as possible.

The following process types are defined for mysqlmanagerd:

mysqlmanagerd_t

Note: semanage permissive -a mysqlmanagerd_t can be used to make the process type mysqlmanagerd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS

SELinux policy is customizable based on least access required. mysqlmanagerd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run mysqlmanagerd with the tightest access possible.

If you want to allow all daemons to write corefiles to /, you must turn on the daemons_dump_core boolean. Disabled by default.

setsebool -P daemons_dump_core 1

If you want to enable cluster mode for daemons, you must turn on the daemons_enable_cluster_mode boolean. Enabled by default.

setsebool -P daemons_enable_cluster_mode 1

If you want to allow all daemons to use tcp wrappers, you must turn on the daemons_use_tcp_wrapper boolean. Disabled by default.

setsebool -P daemons_use_tcp_wrapper 1

If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. Disabled by default.

setsebool -P daemons_use_tty 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

PORT TYPES

SELinux defines port types to represent TCP and UDP ports.

You can see the types associated with a port by using the following command:

semanage port -l

Policy governs the access confined processes have to these ports. SELinux mysqlmanagerd policy is very flexible allowing users to setup their mysqlmanagerd processes in as secure a method as possible.

The following port types are defined for mysqlmanagerd:

mysqlmanagerd_port_t

Default Defined Ports: tcp 2273

MANAGED FILES

The SELinux process type mysqlmanagerd_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.

cluster_conf_t

        /etc/cluster(/.*)?

cluster_var_lib_t

        /var/lib/pcsd(/.*)?

       /var/lib/cluster(/.*)?

       /var/lib/openais(/.*)?

       /var/lib/pengine(/.*)?

       /var/lib/corosync(/.*)?

       /usr/lib/heartbeat(/.*)?

       /var/lib/heartbeat(/.*)?

       /var/lib/pacemaker(/.*)?

cluster_var_run_t

        /var/run/crm(/.*)?

       /var/run/cman_.*

       /var/run/rsctmp(/.*)?

       /var/run/aisexec.*

       /var/run/heartbeat(/.*)?

       /var/run/corosync-qnetd(/.*)?

       /var/run/corosync-qdevice(/.*)?

       /var/run/cpglockd.pid

       /var/run/corosync.pid

       /var/run/rgmanager.pid

       /var/run/cluster/rgmanager.sk

mysqlmanagerd_var_run_t

        /var/run/mysqld/mysqlmanager.*

root_t

        /

       /initrd

FILE CONTEXTS

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 lsP Policy governs the access confined processes have to these files. SELinux mysqlmanagerd policy is very flexible allowing users to setup their mysqlmanagerd processes in as secure a method as possible.

STANDARD FILE CONTEXT

SELinux defines the file context types for the mysqlmanagerd, if you wanted to store files with these types in a diffent paths, you need to execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t mysqlmanagerd_var_run_t '/srv/mymysqlmanagerd_content(/.*)?'
restorecon -R -v /srv/mymysqlmanagerd_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for mysqlmanagerd:

mysqlmanagerd_exec_t

- Set files with the mysqlmanagerd_exec_t type, if you want to transition an executable to the mysqlmanagerd_t domain.

mysqlmanagerd_initrc_exec_t

- Set files with the mysqlmanagerd_initrc_exec_t type, if you want to transition an executable to the mysqlmanagerd_initrc_t domain.

mysqlmanagerd_var_run_t

- Set files with the mysqlmanagerd_var_run_t type, if you want to store the mysqlmanagerd files under the /run or /var/run 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.

COMMANDS

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 port can also be used to manipulate the port definitions

semanage boolean can also be used to manipulate the booleans

system-config-selinux is a GUI tool available to customize SELinux policy settings.
