In this course, you'll learn how to properly secure your websites, data, and DNS infrastructure. You'll integrate industry-standard Linux encryption tools like OpenSSL with the X.509 public key certificate standard.
If you're responsible for the security and reliability of IT resources of any kind, then encryption is your friend. Not only is it unwise to try to manage sensitive health records or credit card transactions without using strong encryption to obscure the data, but, in many cases, it's against the law. It's not only your data that's at risk; if your website and DNS service aren't protected by some kind of public key certificates, it could be just a matter of time before your servers will be hijacked by criminal hackers. In this course, Linux Encryption Security, you'll cover everything you need to know to apply proper encryption to the Linux systems behind your website, stored and mobile data, and DNS infrastructure. First, you'll learn how to configure and administrate industry-standard packages, such as OpenSSL, X.509 certificates, SSL/TLS, BIND, Apache httpd, eCryptfs, and Cryptsetup. Next, you'll explore encrypting the files on a PC or mobile device. Finally, you'll discover how to secure the all-important DNS service connecting your customers and users to your web-facing resources. By the end of this course, you'll feel confident tackling an assortment of possible security risk and vulnerabilities.

Course Overview Your small business ecommerce website is about to go live, but you haven't yet addressed the issue of authentication and SSL certificates, and the guy from the company handling your credit card processing is on the phone. Infrastructure security is or should be on everybody's minds right now. Websites, mobile devices, even your local data drives, everything is potentially vulnerable. Obscuring sensitive data through sophisticated encryption is one of the few things that can really reduce your risk of exposure. In this course I'll show you how to configure and manage encryption on Linux-based systems. You'll learn to encrypt your website using either a well-known certificate authority or by issuing your own certificates. We'll also cover encrypting the files on a PC or a mobile device, and how to secure the all-important DNS service connecting your customers and users to your web facing resources. If you're reasonably comfortable working on the Linux command line with file systems, networks, and package management, and have at least a basic, general knowledge of TCP/IP networking protocols, then you'll enjoy taking this course. If you're responsible for resources that might be vulnerable to security risks, then you'd better take the course.
