6 pcscd_selinux - Security Enhanced Linux Policy for the pcscd processes
7
9 Security-Enhanced Linux secures the pcscd processes via flexible manda‐
10 tory access control.
11 The pcscd processes execute with the pcscd_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep pcscd_t
19
23 The pcscd_t SELinux type can be entered via the pcscd_exec_t file type.
24 The default entrypoint paths for the pcscd_t domain are the following:
26 /usr/sbin/pcscd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 pcscd policy is very flexible allowing users to setup their pcscd pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for pcscd:
40 pcscd_t
42 Note: semanage permissive -a pcscd_t can be used to make the process
44 type pcscd_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. pcscd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run pcscd with the tightest access possible.
53 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58 setsebool -P fips_mode 1
60 If you want to allow confined applications to use nscd shared memory,
64 you must turn on the nscd_use_shm boolean. Disabled by default.
65 setsebool -P nscd_use_shm 1
67
71 The SELinux process type pcscd_t can manage files labeled with the fol‐
72 lowing file types. The paths listed are the default paths for these
73 file types. Note the processes UID still need to have DAC permissions.

123 SELinux requires files to have an extended attribute to define the file
124 type.
125 You can see the context of a file using the -Z option to ls
127 Policy governs the access confined processes have to these files.
129 SELinux pcscd policy is very flexible allowing users to setup their
130 pcscd processes in as secure a method as possible.
131 EQUIVALENCE DIRECTORIES
133 pcscd policy stores data with multiple different file context types
136 under the /var/run/pcscd directory. If you would like to store the
137 data in a different directory you can use the semanage command to cre‐
138 ate an equivalence mapping. If you wanted to store this data under the
139 /srv dirctory you would execute the following command:
140 semanage fcontext -a -e /var/run/pcscd /srv/pcscd
142 restorecon -R -v /srv/pcscd
143 STANDARD FILE CONTEXT
145 SELinux defines the file context types for the pcscd, if you wanted to
147 store files with these types in a diffent paths, you need to execute
148 the semanage command to sepecify alternate labeling and then use
149 restorecon to put the labels on disk.
150 semanage fcontext -a -t pcscd_var_run_t '/srv/mypcscd_content(/.*)?'
152 restorecon -R -v /srv/mypcscd_content
153 Note: SELinux often uses regular expressions to specify labels that
155 match multiple files.
156 The following file types are defined for pcscd:
158 pcscd_exec_t
162 - Set files with the pcscd_exec_t type, if you want to transition an
164 executable to the pcscd_t domain.
165 pcscd_initrc_exec_t
169 - Set files with the pcscd_initrc_exec_t type, if you want to transi‐
171 tion an executable to the pcscd_initrc_t domain.
172 pcscd_var_run_t
176 - Set files with the pcscd_var_run_t type, if you want to store the
178 pcscd files under the /run or /var/run directory.
179 Paths:
182 /var/run/pcscd(/.*)?, /var/run/pcscd.events(/.*)?,
183 /var/run/pcscd.pid, /var/run/pcscd.pub, /var/run/pcscd.comm
184 Note: File context can be temporarily modified with the chcon command.
187 If you want to permanently change the file context you need to use the
188 semanage fcontext command. This will modify the SELinux labeling data‐
189 base. You will need to use restorecon to apply the labels.
190
193 semanage fcontext can also be used to manipulate default file context
194 mappings.
195 semanage permissive can also be used to manipulate whether or not a
197 process type is permissive.
198 semanage module can also be used to enable/disable/install/remove pol‐
200 icy modules.
201 semanage boolean can also be used to manipulate the booleans
203 system-config-selinux is a GUI tool available to customize SELinux pol‐
206 icy settings.
