15 Online Courses to Become a Cyber Security Master

In this article you can find online Cyber Security courses to enhance your knowledge.

Computer security, cybersecurity (cyber security), or information technology security (IT security) is the protection of computer systems and networks from information disclosure, theft of, or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.

The field has become significant due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of “smart” devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is also one of the significant challenges in the contemporary world, due to its complexity, both in terms of political usage and technology. Its primary goal is to ensure the system’s dependability, integrity, and data privacy.

With our following 15 online courses, you’ll be able to master your Cyber Security skills.

Free Automated A+ Graded SSL Certificates with Let’s Encrypt
Nick Janetakis via Udemy
Learn How to Get a Secure Lock Icon for Your Site. Because Nowadays Hosting an Insecure Site Isn’t Good Enough. Search engines (especially Google) and major browser vendors are really cracking down on insecure sites. Google ranks insecure pages (HTTP) worse than secure pages (HTTPS). As of mid–2014 Google has openly stated that HTTPS is now part of their page rank algorithm. Simply put, insecure sites being served over HTTP will rank worse than secure sites being served over HTTPS. Chrome, FireFox and other browser vendors are adding more and more visual cues that make even non–technical folks aware that your site is dangerous to view. It won’t take long until all insecure sites are seen as being malicious and untrustworthy, even if you’re technically not doing anything wrong. Although honestly, I would classify not securing your site as doing your visitors a disservice.

Cryptography I (FREE)
Dan Boneh via Coursera
Cryptography is an indispensable tool for protecting information in computer systems. In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real–world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public–key techniques that let two parties generate a shared secret key. Throughout the course participants will be exposed to many exciting open problems in the field and work on fun (optional) programming projects. In a second course (Crypto II) we will cover more advanced cryptographic tasks such as zero–knowledge, privacy mechanisms, and other forms of encryption.
