Why Web Security Matters

[MUSIC] 0:00 Welcome I'm Alena, a teacher here at Treehouse. 0:04 Whatever your language of choice, PHP, .NET, JavaScript, 0:08 Python, Java or any other language, security is for everyone. 0:12 In this course, we're going to learn about some of the most important web security 0:18 fundamentals, including HTTPS, authentication and 0:22 authorization, patch management, and compliance. 0:27 Each of these topics is a focus in the field of web security. 0:31 Which falls beneath the larger umbrella of security in general. 0:35 Security in general, however, can be applied to nearly any technology. 0:39 As shown here, security ranges up and down the modern networking stack. 0:44 When we think of security, we may think of protecting the physical 1s and 0:49 0s running across the cable, which would be a very low level. 0:53 Or, we may think of protecting our web applications 0:57 from bad people intercepting traffic, which would be at the application level. 1:00 Regardless, it's important to realize that security is a very broad topic. 1:07 We'll only be diving into the parts of security that lie in the web protocols 1:12 at the application layer of most networking stacks. 1:17 Web security concerns the security of websites, 1:21 applications, APIs and services in general. 1:24 It covers a wide range of topics from writing secure code 1:28 to protecting your applications once they're deployed. 1:32 On the modern web, security varies widely from site to site. 1:36 Our goal is to teach you the basics. 1:40 And insure that you have the ability to explore more advance concepts 1:42 that will allow you to secure your sites, APIs, services, and 1:47 applications against malicious entities. 1:52 Without building and maintaining secure applications, your users are at risk, and 1:55 your company's assets maybe vulnerable. 2:00 Within nearly every competent organization, 2:03 someone should be responsible for security. 2:06 And at least every developer should know the basics. 2:09 As developers, we should be aware of the potential vulnerabilities 2:13 introduced into the code base with each feature and every bug fix. 2:17 No matter what your job at your company, organization, or even side project, 2:22 you should have security in mind when you deploy your web applications. 2:27 Especially if you have users you wish to protect. 2:31 By working together and putting security first, we can all reduce the impact 2:35 that data breaches and malicious entities cause to our users. 2:40
