## Securing Adobe Reader

### TOMOYO

Follow the instructions here to install TOMOYO. Please note that this section describes using TOMOYO 2.5.

Note that the instructions below describe securing acroreadAUR.

- Open `/etc/tomoyo/exception_policy.conf` file and add these lines:

    path_group PDF_FILES /\{\*\}/\*.pdf
    path_group THEMES_FILES /usr/share/themes/\{\*\}/\*
    path_group THEMES_FILES /usr/share/themes/\*
    path_group FONTS_DIRS /usr/share/fonts/\{\*\}/
    path_group FONTS_FILES /usr/share/fonts/\{\*\}/\*
    path_group FONTS_FILES /usr/share/fonts/\*
    path_group ACROREAD_FILES /opt/Adobe/Reader9/\{\*\}/\*
    path_group ACROREAD_FILES /opt/Adobe/Reader9/\*
    path_group ACROREAD_FILES /home/\*/.adobe/Acrobat/\{\*\}/\*
    path_group ACROREAD_FILES /home/\*/.adobe/Acrobat/\*
    path_group ACROREAD_DIRS /home/\*/.adobe/Acrobat/\{\*\}/
    path_group ACROREAD_DIRS /home/\*/.adobe/\{\*\}/
    initialize_domain /usr/bin/acroread from any

- Then open `/etc/tomoyo/domain_policy.conf` and add the following lines:

- After finishing editing reload TOMOYO config files by executing these commands:

    # tomoyo-loadpolicy -df </etc/tomoyo/domain_policy.conf
    # tomoyo-loadpolicy -ef </etc/tomoyo/exception_policy.conf

Voilà — your Adobe Reader is sandboxed now.

Please note that this config is generated on 64-bit Arch system, and some of your ioctls and library paths may differ from mentioned above. So in order to fine-tune TOMOYO config for your Adobe Reader load `tomoyo-auditd` daemon:

    # systemctl start tomoyo-auditd

Then go to `/var/log/tomoyo` folder and start watching `reject_003.log`:

    tail -f reject_003.log

The output of this command will show you rejected actions for Adobe Reader, so you'll be able to add them to `domain_policy.conf` file if needed.

Detailed guide about TOMOYO configuring can be found here.
