Web application security

Web application security is the process of shielding websites and online services against security threats that leave an application exposed. Web application security is essential in protecting a user’s data from a malicious user who plans to cause harm to that data.

Mozilla Observatory

Once you have deployed your application, be sure to check out the Mozilla observatory. It will scan your website for potential security flaws. Once the scan is complete you will get a breakdown of what is good and what needs to be improved, as well as a cool overall score, just like when you received that ‘amazing’ math test back in high school.

DJ Checkup

Another great site to scan your website for potential security flaws is DJ checkup. It was specifically designed to test Django websites. It checks for all the issues that are typically found in insecure Django web applications and provides you with a list of problems to fix and improve upon.

SSL Trust

SSL stands for Secure Sockets Layer and it forms the basis for what we know as HTTPS (HyperText Transfer Protocol Secure). It ensures that all communication between our client and server remains encrypted and secure. Hence, an SSL certificate is used to provide our websites with HTTPS.

SSL Trust is a service that provides us with a detailed SSL security test, as well as testing our website for numerous other issues. It is very easy to interpret the results of the test since everything is either a pass or a fail.

Sucuri SiteCheck

This is one of the most popular open-source web security tools. Like the rest of the tools available, all you have to do is simply copy and paste your website's URL and the report will be generated.

The site checks for common issues such as:

- Website errors

- Old and out-of-date software

- Malware

- Blacklisting status

Of course, no web security tool will be able to catch all loopholes and find every vulnerability in a system, but you'll at least get a strong sense of what are the most important aspects to fix and consider.

Research, research, and research

No matter how much effort you put in to protect your website, it will never be 100% secure, but that doesn’t mean you can’t do some research of your own and try to make it as secure as possible.
