7 processes
8
10 Security-Enhanced Linux secures the certwatch processes via flexible
11 mandatory access control.
12
13 The certwatch processes execute with the certwatch_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep certwatch_t
20
21
22
24 The certwatch_t SELinux type can be entered via the certwatch_exec_t
25 file type.
26
27 The default entrypoint paths for the certwatch_t domain are the follow‐
28 ing:
29
30 /etc/cron.daily/certwatch
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 certwatch policy is very flexible allowing users to setup their cert‐
40 watch processes in as secure a method as possible.
41
42 The following process types are defined for certwatch:
43
44 certwatch_t
45
46 Note: semanage permissive -a certwatch_t can be used to make the
47 process type certwatch_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. cert‐
54 watch policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run certwatch with the tightest access
56 possible.
57
58
59
60 If you want to deny any process from ptracing or debugging any other
61 processes, you must turn on the deny_ptrace boolean. Enabled by
62 default.
63
64 setsebool -P deny_ptrace 1
65
66
67
68 If you want to allow any process to mmap any file on system with
69 attribute file_type, you must turn on the domain_can_mmap_files bool‐
70 ean. Enabled by default.
71
72 setsebool -P domain_can_mmap_files 1
73
74
75
76 If you want to allow all domains write to kmsg_device, while kernel is
77 executed with systemd.log_target=kmsg parameter, you must turn on the
78 domain_can_write_kmsg boolean. Disabled by default.
79
80 setsebool -P domain_can_write_kmsg 1
81
82
83
84 If you want to allow all domains to use other domains file descriptors,
85 you must turn on the domain_fd_use boolean. Enabled by default.
86
87 setsebool -P domain_fd_use 1
88
89
90
91 If you want to allow all domains to have the kernel load modules, you
92 must turn on the domain_kernel_load_modules boolean. Disabled by
93 default.
94
95 setsebool -P domain_kernel_load_modules 1
96
97
98
99 If you want to allow all domains to execute in fips_mode, you must turn
100 on the fips_mode boolean. Enabled by default.
101
102 setsebool -P fips_mode 1
103
104
105
106 If you want to enable reading of urandom for all domains, you must turn
107 on the global_ssp boolean. Disabled by default.
108
109 setsebool -P global_ssp 1
110
111
112
114 The SELinux process type certwatch_t can manage files labeled with the
115 following file types. The paths listed are the default paths for these
116 file types. Note the processes UID still need to have DAC permissions.
117
118 auth_cache_t
119
120 /var/cache/coolkey(/.*)?
121
122
124 SELinux requires files to have an extended attribute to define the file
125 type.
126
127 You can see the context of a file using the -Z option to ls
128
129 Policy governs the access confined processes have to these files.
130 SELinux certwatch policy is very flexible allowing users to setup their
131 certwatch processes in as secure a method as possible.
132
133 The following file types are defined for certwatch:
134
135
136
137 certwatch_exec_t
138
139 - Set files with the certwatch_exec_t type, if you want to transition
140 an executable to the certwatch_t domain.
141
142
143
144 Note: File context can be temporarily modified with the chcon command.
145 If you want to permanently change the file context you need to use the
146 semanage fcontext command. This will modify the SELinux labeling data‐
147 base. You will need to use restorecon to apply the labels.
148
149
151 semanage fcontext can also be used to manipulate default file context
152 mappings.
153
154 semanage permissive can also be used to manipulate whether or not a
155 process type is permissive.
156
157 semanage module can also be used to enable/disable/install/remove pol‐
158 icy modules.
159
160 semanage boolean can also be used to manipulate the booleans
161
162
163 system-config-selinux is a GUI tool available to customize SELinux pol‐
164 icy settings.
