AppArmor

AppArmor是一个Linux安全模块（LSM）实现基于名字的强制访问控制（MAC）。我该如何开始/停止/重新启动AppArmor的Ubuntu Linux操作系统下或openSUSE/SUSE企业级Linux服务器系统，IBM硬件上运行？

AppArmor是一个有效的和易于使用的Linux应用安全系统。 AppArmor的则保护Linux操作系统及应用程序从内部或外部的威胁，甚至零日攻击，执行良好的行为和防止甚至未知的应用程序漏洞被利用。

AppArmor security policies completely define what system resources individual applications can access, and with what privileges. You need to use the following init.d scripts to control AppArmor:

[a] Debian/Ubuntu Linux - /etc/init.d/apparmor ( or use sudo service apparmor command).

[b] OpenSUSE / Suse Enterprise Linux - /etc/init.d/boot.apparmor

Task: Stop Apparmor

Type the following command:

## debian/ubuntu 
sudo /etc/init.d/apparmor stop
 
## Suse
/etc/init.d/boot.apparmor stop
 

Task: Start Apparmor

Type the following command:

## debian/ubuntu 
sudo /etc/init.d/apparmor start
 
## Suse
/etc/init.d/boot.apparmor start
 

Task: Restart Apparmor

Type the following command:

## debian/ubuntu 
sudo /etc/init.d/apparmor restart
 
## Suse
/etc/init.d/boot.apparmor restart
 

Task: See the current Apparmor status

Type the following command:

## debian/ubuntu 
sudo /etc/init.d/apparmor status
 
## Suse
/etc/init.d/boot.apparmor status
