6 acct_selinux - Security Enhanced Linux Policy for the acct processes
7
9 Security-Enhanced Linux secures the acct processes via flexible manda‐
10 tory access control.
11 The acct processes execute with the acct_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15 For example:
17 ps -eZ | grep acct_t
19
23 The acct_t SELinux type can be entered via the acct_exec_t file type.
24 The default entrypoint paths for the acct_t domain are the following:
26 /etc/cron.(daily|monthly)/acct, /sbin/accton, /usr/sbin/accton
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 acct policy is very flexible allowing users to setup their acct pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for acct:
40 acct_t
42 Note: semanage permissive -a acct_t can be used to make the process
44 type acct_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. acct
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run acct with the tightest access possible.
53 If you want to allow all daemons the ability to read/write terminals,
57 you must turn on the allow_daemons_use_tty boolean. Disabled by
58 default.
59 setsebool -P allow_daemons_use_tty 1
61 If you want to allow all domains to use other domains file descriptors,
65 you must turn on the allow_domain_fd_use boolean. Enabled by default.
66 setsebool -P allow_domain_fd_use 1
68 If you want to allow sysadm to debug or ptrace all processes, you must
72 turn on the allow_ptrace boolean. Disabled by default.
73 setsebool -P allow_ptrace 1
75 If you want to allow all domains to have the kernel load modules, you
79 must turn on the domain_kernel_load_modules boolean. Disabled by
80 default.
81 setsebool -P domain_kernel_load_modules 1
83 If you want to allow all domains to execute in fips_mode, you must turn
87 on the fips_mode boolean. Enabled by default.
88 setsebool -P fips_mode 1
90 If you want to enable reading of urandom for all domains, you must turn
94 on the global_ssp boolean. Disabled by default.
95 setsebool -P global_ssp 1

101 The SELinux process type acct_t can manage files labeled with the fol‐
102 lowing file types. The paths listed are the default paths for these
103 file types. Note the processes UID still need to have DAC permissions.

108 /var/log/account(/.*)?

142 SELinux requires files to have an extended attribute to define the file
143 type.
144 You can see the context of a file using the -Z option to ls
146 Policy governs the access confined processes have to these files.
148 SELinux acct policy is very flexible allowing users to setup their acct
149 processes in as secure a method as possible.
150 STANDARD FILE CONTEXT
152 SELinux defines the file context types for the acct, if you wanted to
154 store files with these types in a diffent paths, you need to execute
155 the semanage command to sepecify alternate labeling and then use
156 restorecon to put the labels on disk.
157 semanage fcontext -a -t acct_data_t '/srv/myacct_content(/.*)?'
159 restorecon -R -v /srv/myacct_content
160 Note: SELinux often uses regular expressions to specify labels that
162 match multiple files.
163 The following file types are defined for acct:
165 acct_data_t
169 - Set files with the acct_data_t type, if you want to treat the files
171 as acct content.
172 Paths:
175 /var/account(/.*)?, /var/log/account(/.*)?
176 acct_exec_t
179 - Set files with the acct_exec_t type, if you want to transition an
181 executable to the acct_t domain.
182 Paths:
185 /etc/cron.(daily|monthly)/acct, /sbin/accton, /usr/sbin/accton
186 Note: File context can be temporarily modified with the chcon command.
189 If you want to permanently change the file context you need to use the
190 semanage fcontext command. This will modify the SELinux labeling data‐
191 base. You will need to use restorecon to apply the labels.
192
195 semanage fcontext can also be used to manipulate default file context
196 mappings.
197 semanage permissive can also be used to manipulate whether or not a
199 process type is permissive.
200 semanage module can also be used to enable/disable/install/remove pol‐
202 icy modules.
203 semanage boolean can also be used to manipulate the booleans
205 system-config-selinux is a GUI tool available to customize SELinux pol‐
208 icy settings.
