The Best Practices Of Ruby on Rails Security

When it comes to safer web applications, ensuring the safety of the frameworks is the key. Ruby on Rails is one such framework popular among the developers for creating secure Ruby applications. It is because Rails already comes with some built-in security features that facilitate the developers in creating a secure environment. However, one may not solely rely on these features as the probabilities of vulnerabilities always exist. The other option to ensure online security is to use a VPN, but that will also keep you busy looking for answers to your query “when I connect to VPN I lose internet”, etc.

Security measures

So how would you ensure safe working? Well, things can be much safer and easier if you simply follow the best practices of Ruby on Rails. These include the security measures you should take alongside using a VPN and employing the ROR built-in security features.

  1. The first thing to look for adequate ROR security is protection against session hijacking. The bad actors are always on the hunt for ways to hijack legitimate users’ sessions to log into an app. These attacks can occur regardless of HTTP or HTTPS protocols. To hijack sessions, one of the common exploit methods employed by the attackers to steal cookies is cross-site scripting (XSS) attacks. To prevent such attacks, the developers can adopt random values for cookies. This will prevent the attacker from guessing the previous or the next cookies. Besides, they can also establish secure connections for every incoming HTTP request as well.
  2. The other common attack faced by the users is CSRF or cross-site request forgeries. Here, the attackers do not steal cookies, rather they redirect the innocent users to some CSRF vulnerable site. Such attacks are common for financial hacks. To prevent such CSRF attacks on Ruby on Rails, the developers can add authenticity_token to the HTML responses, thus enabling ROR to verify each request before processing.

Other attacks

Apart from these, the other common attacks faced by the apps include SQL injection attacks. These attacks are common for database hacks where the attacker needs to bypass login authentications. An attacker can inject a malicious code to a vulnerable site to achieve his targets. In the case of Rails, the attackers may exploit the built-in security feature ActiveRecords. This default feature compels all Rails apps to interact with a database via this ORM, where a slight carelessness can lead to SQL injection vulnerabilities. To prevent these attacks, the ROR developers should remain careful while using Rails ActiveRecord.
