Linux has an excellent reputation as a secure and efficient operating system. That is why it is an indispensable building block in the construction of secure computer infrastructures. This course provides in-depth knowledge about the use of various security techniques based on Linux, such as the configuration and operation of Linux systems as firewalls and routers, the Secure Shell, or OpenVPN for virtual private networks. It also goes into detail about techniques you can use to secure Linux systems yourself that function as web or mail servers, for example. You will also learn the basics of using intrusion detection systems such as Snort and security scanners such as OpenVAS. (LPI 202)
