Course Overview
Security is always a concern, and with major security holes like Shellshock and Heartbleed being announced regularly, it’s more critical than ever to secure the data you are liable for. This course will walk you through the many risks and threats that exist, show you how to use best practices and other open-source tools to mitigate or counteract those threats, and teach you what you need to know to detect and recover from those attacks that do happen.
Who should attend
Any professional IT manager and administrator should benefit from this course. Software developers who need to improve their knowledge of security concepts and strategies will also find a great deal of information that applies to their responsibilities.
Prerequisites
Attendees should:
- Have a solid understanding of core local system administration and networking concepts equivalent to that obtained from Linux for System Administrators (LFS301) and Linux for System Engineers (LFS311).
- Be experienced with Linux (or more generally UNIX), especially at the command line level.
