Web application security: Definition and best practices you need to know

Advancements in web applications, web services, and other technology have paved the way for eCommerce business. Like any responsible website owner, you are probably well aware of the importance of web application security. If you think that your website is safe, you’re wrong.

This is the central component of any web-based business. The global nature of the Internet exposes web properties to attack from various levels of scale and complexity. Web application security deals specifically with the security surrounding web applications. So now, we would like to show you guys the definition of this term. Also, the best practices that you may need to know. Let’s get into it!

What is web application security?

Web Application Security is the process of protecting websites and online services against different security threats that exploit vulnerabilities in an application’s code. Common targets for web application attacks are content management systems (e.g., WordPress), database administration tools (e.g., phpMyAdmin), and SaaS applications.

Organizations failing to secure their web applications run the risk of being attacked as a result. Among other consequences, this can result in information theft and damaged client relationships. So, web application security defends against such defects.

What are the common web application security vulnerabilities?

As a result, attacks against web apps range from targeted database manipulation to large-scale network disruption. So, let’s explore some of the common methods of attack or “vectors” commonly exploited.

#1. SQL Injection – the most prominent web application security

SQL is a method by which an attacker exploits vulnerabilities in the way a database executes search queries. This deflection occurs when a perpetrator uses malicious SQL code to manipulate a backend database so it reveals information.

#2. Denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks

Through a variety of vectors, attackers are able to overload a targeted server. When a server is no longer able to effectively process incoming requests, it begins to behave sluggishly. Eventually, it will deny service to incoming requests from legitimate users.

#3. Cross-site request forgery (CSRF) – the monetary vulnerability of web application security

This is the attack that could result in data theft. By leveraging the account privileges of a user, an attacker is able to send a fake request as the user. Once a user’s account has been collapsed, the attacker can exfiltrate, destroy, or modify important information.

#4. Cross-site scripting (XSS)

XSS is one of the most dangerous injection attacks targeting users in order to access sensitive information. This could be done by injecting client-side scripts into a webpage. Also, reflected XSS takes place when a malicious script is reflected off of an application onto a user’s browser. This is quite dangerous if you don’t intend to update your web application security.

What are the best practices of web application security?

Knowing the most prominent, yet dangerous factors, we have to boost the security of our web application as a result. Important steps in protecting web apps from falling apart include a lot of practices instead.

So, let’s check out the best practices of this module that you may need to know. 

#1. Web Application Firewall (WAF) – the protector against Application Layer attacks

A WAF helps protect a web application against anonymous HTTP traffic. By placing a filtration barrier, the WAF is able to protect against attacks. As a result, your web application security will be much more developed, as well as your eCommerce store will be safe for users to access.

#2. DDoS mitigation

So, a commonly used method for disrupting a web application is the use of distributed DDoS attacks. Cloudflare decreases attacks through a variety of ways to properly route authorized requests without a loss of service. In recent years, with the help of this practice, the web application security won’t have to worry too much about that.

#3. DNS Security – DNSSEC web application security protection

DNS Security

The domain name system or DNS is certainly the phonebook of the Internet. It represents the way in which an Internet tool such as a web browser looks up the correct server. As a result, hackers will attempt to rob this DNS request process through a variety of methods. If DNS is the phonebook of the Internet, then DNSSEC is a shield for caller ID.

Final words

That should be it! Here is the complete definition of web application security, as well as some of the best practices that you should know for your business. All in all, you should put the proper security best practices in place. They will help ensure that your applications remain safe for everyone to use as a result.
