anon_sftpd_selinux(8)	   SELinux Policy anon_sftpd	 anon_sftpd_selinux(8)

NAME
       anon_sftpd_selinux  - Security Enhanced Linux Policy for the anon_sftpd
       processes

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

       The  anon_sftpd	processes  execute with the anon_sftpd_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 anon_sftpd_t

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 ps

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

       The following process types are defined for anon_sftpd:

       anon_sftpd_t

       Note: semanage permissive -a anon_sftpd_t  can  be  used	 to  make  the
       process	type  anon_sftpd_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.
       anon_sftpd policy is extremely flexible and has several	booleans  that
       allow you to manipulate the policy and run anon_sftpd with the tightest
       access possible.

       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

MANAGED FILES
       The SELinux process type anon_sftpd_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.

       public_content_rw_t

	    /var/spool/abrt-upload(/.*)?

SHARING FILES
       If  you	want to share files with multiple domains (Apache, FTP, rsync,
       Samba), you can set a file context of public_content_t and  public_con‐
       tent_rw_t.   These  context  allow any of the above domains to read the
       content.	 If you want a particular domain to write to  the  public_con‐
       tent_rw_t domain, you must set the appropriate boolean.

       Allow  anon_sftpd  servers  to  read  the  /var/anon_sftpd directory by
       adding the public_content_t file type to the directory and by restoring
       the file type.

       semanage fcontext -a -t public_content_t "/var/anon_sftpd(/.*)?"
       restorecon -F -R -v /var/anon_sftpd

       Allow  anon_sftpd servers to read and write /var/anon_sftpd/incoming by
       adding the public_content_rw_t type to the directory and	 by  restoring
       the  file  type.	  You  also  need to turn on the anon_sftpd_anon_write
       boolean.

       semanage fcontext  -a  -t  public_content_rw_t  "/var/anon_sftpd/incom‐
       ing(/.*)?"
       restorecon -F -R -v /var/anon_sftpd/incoming
       setsebool -P anon_sftpd_anon_write 1

       If you want to determine whether sftpd can modify public files used for
       public file transfer services. Directories/Files must be	 labeled  pub‐
       lic_content_rw_t., you must turn on the sftpd_anon_write boolean.

       setsebool -P sftpd_anon_write 1

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 pol‐
       icy modules.

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux pol‐
       icy settings.
