SuSE Firewall 2 effectively protects your computer against intruders. When you are online, this wall blocks everything you do not explicity request or send. Of course, you can still freely view web pages, download program files via FTP, update your own web pages, and transmit e-mail.
Using SuSE Firewall 2, which is included in SuSE Linux, you can define in detail who and what is permitted to access your PC.

In Linux, you can use the GPG or OpenPGP to encrypt your mail in such a way that only the recipient can read it. Thus, no unauthorized individuals can intercept your e-mail. Methods such as "Openssh" and "Openssl" make remote connections virtually impossible to crack. A highlight of SuSE Linux security technology: the "crypto file system". Secret or sensitive data is encrypted on your own PC. Using the crypto file system, you can encrypt partitions and make them unusable for unauthorized persons.

Scene: You start several programs simultaneously, e.g. you browse through the Internet while at the same time saving a larger document. Suddenly it happens: the screen turns blue and the only way out is usually a system reboot. Due to its perfect multitasking (= multiple processes can run concurrently), Linux provides a maximum of operating stability. Therefore, it comes as no surprise that Linux is frequently deployed in servers - an area where stable, uninterrupted operation is crucial.
