<h1>Web Application Security</h1>

<p>Website security must be thought about while building every level of the web

<h2>Web security learning checklist</h2>

Read and understand the major web application security flaws that are

commonly exploited by malicious actors. These include cross-site request

forgery (CSRF), cross-site scripting (XSS), SQL injection and session

hijacking. The

<a href="https://www.owasp.org/index.php/Top_10_2013-Top_10">OWASP top 10 web application vulnerabilities list</a>

is a great place to get an overview of these topics.</p>

Determine how the framework you've chosen mitigates these vulnerabilities.</p>

Ensure your code implements the mitigation techniques for your framework. </p>

Think like an attacker and actively work to break into your own system. If

you do not have enough experience to confidently break the security consider

hiring a known white hat attacker. Have her break the application's security,

report the easiest vulnerabilities to exploit in your app and help implement

protections against those weaknesses.</p>

Recognize that no system is ever totally secure. However, the more popular

an application becomes the more attractive a target it is to attackers.

Reevaluate your web application security on a frequent basis.</p>
