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. Enabled 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.

124 SELinux requires files to have an extended attribute to define the file
125 type.
126 You can see the context of a file using the -Z option to ls
128 Policy governs the access confined processes have to these files.
130 SELinux pcscd policy is very flexible allowing users to setup their pc‐
131 scd processes in as secure a method as possible.
132 EQUIVALENCE DIRECTORIES
134 pcscd policy stores data with multiple different file context types un‐
137 der the /var/run/pcscd directory. If you would like to store the data
138 in a different directory you can use the semanage command to create an
139 equivalence mapping. If you wanted to store this data under the /srv
140 directory you would execute the following command:
141 semanage fcontext -a -e /var/run/pcscd /srv/pcscd
143 restorecon -R -v /srv/pcscd
144 STANDARD FILE CONTEXT
146 SELinux defines the file context types for the pcscd, if you wanted to
148 store files with these types in a diffent paths, you need to execute
149 the semanage command to specify alternate labeling and then use re‐
150 storecon to put the labels on disk.
151 semanage fcontext -a -t pcscd_var_run_t '/srv/mypcscd_content(/.*)?'
153 restorecon -R -v /srv/mypcscd_content
154 Note: SELinux often uses regular expressions to specify labels that
156 match multiple files.
157 The following file types are defined for pcscd:
159 pcscd_exec_t
163 - Set files with the pcscd_exec_t type, if you want to transition an
165 executable to the pcscd_t domain.
166 pcscd_initrc_exec_t
170 - Set files with the pcscd_initrc_exec_t type, if you want to transi‐
172 tion an executable to the pcscd_initrc_t domain.
173 pcscd_var_run_t
177 - Set files with the pcscd_var_run_t type, if you want to store the pc‐
179 scd files under the /run or /var/run directory.
180 Paths:
183 /var/run/pcscd(/.*)?, /var/run/pcscd.events(/.*)?, /var/run/pc‐
184 scd.pid, /var/run/pcscd.pub, /var/run/pcscd.comm
185 Note: File context can be temporarily modified with the chcon command.
188 If you want to permanently change the file context you need to use the
189 semanage fcontext command. This will modify the SELinux labeling data‐
190 base. You will need to use restorecon to apply the labels.
191
194 semanage fcontext can also be used to manipulate default file context
195 mappings.
196 semanage permissive can also be used to manipulate whether or not a
198 process type is permissive.
199 semanage module can also be used to enable/disable/install/remove pol‐
201 icy modules.
202 semanage boolean can also be used to manipulate the booleans
204 system-config-selinux is a GUI tool available to customize SELinux pol‐
207 icy settings.
